Trachypachidae


Systolosoma
Trachypachus
The false ground beetles are a family (Trachypachidae) of beetles that generally resemble small ground beetles, but that are distinguished by the large coxae of their rearmost legs. Only six species are known in the family, with four species of Trachypachus found in northern Eurasia and northern North America, and two species of Systolosoma in Chile. Their habits are similar to those of the ground beetles; they are usually found in the leaf litter of conifer forests. To quote G. E. Ball, "the most interesting thing about this small family is its uncertain phylogenetic relationships"; it has been classified as a subfamily of Carabidae, and as a family been placed in several different positions relative to other beetle families.

See subgroups of the order Coleoptera Beetles are one of the main groups of insects. Their order, Coleoptera (meaning "sheathed wing"), has more species in it than any other order in the entire animal kingdom. Forty percent of all described insect species are beetles (about 350,000 species), and new species are regularly discovered. Estimates put the total number of species — described and undescribed — at between 5 and 8 million. This is why, when J. B. S. Haldane, a British geneticist, was asked what his studies of nature revealed about God, he replied, "An inordinate fondness for beetles". Beetles can be found in almost all habitats, but are not known to occur in the sea or in the polar regions. They have a major impact on the ecosystem in three ways: feeding on plants and fungi, breaking down animal and plant debris, and eating other invertebrates. Certain species are agricultural pests in some areas, for example the Colorado potato beetle (Leptinotarsa decemlineata), while other species are important controls of agricultural pests, for example the lady beetles (family Coccinellidae) consume aphids, fruit flies, thrips, and other plant-sucking insects that damage crops.

Anatomy

thrip Bearing in mind the wide diversity and number of species the anatomy of beetles is quite uniform. Beetles are generally characterised by a particularly hard exoskeleton, and the hard wing-cases (elytra) which tend to cover the hind part of the body and protect the second wings, the alae. The elytra are not used in flying, but generally must be raised in order to move the hindwings. In some cases the ability to fly has been lost, characteristically in families such as Carabidae and Curculionidae. After landing, the hindwings are folded below the elytra. In a few families, both the ability to fly and the wing-cases have been lost, with the best known example being the "glowworms" of the family Phengodidae, in which the females are larviform throughout their lives. The bodies of beetles are divided into three sections, the head, the thorax, and the abdomen, and these in themselves may be composed of several further segments. The eyes are compound, and may display some remarkable adabtability, as in the case of the Whirligig beetles (family Gyrinidae), in which the eyes are split to allow a view both above and below the waterline. The dorsal appendage aids the beetle in stalking prey. Antennae can vary greatly and may be filiform, claviform, flabellate or genticulate. Oxygen is taken in via a tracheal system: this takes air in through a series of tubes along the body which is then taken into increasingly finer fibres. Pumping movements of the body force the air through the system. Although beetles have blood, it is not used for oxygen transference, although a heart is present.

Development

heart Beetles are endopterygotes with complete metamorphosis. The larva of a beetle is often called a grub and represents the principal feeding stage of the life-cycle. The eggs of beetles are minute but may be brightly coloured, they are laid in clumps and there may be from several dozen to several thousand eggs laid by a single female. Once the egg hatches the larvae tend to feed voraciously, whether out in the open such as with Ladybird larvae, or within plants such as with leaf beetle larvae. As with lepidoptera, beetle larvae pupate for a period, and from the pupa emerges a fully formed beetle or imago. In some cases there are several transitory larvae stages and this is known as hypermetamorphosis; examples include the blister beetles (family Meloidae).

Physiology

There are few things that a beetle somewhere will not eat, even inorganic matter may be consumed. Some beetles are highly specialised in their diet; for example, the Colorado potato beetle (Leptinotarsa decemlineata) opts almost entirely to colonize plants of the potato family (Solanaceae). Others are generalists, eating both plants and animals. Ground beetles (family Carabidae) and rove beetles (family Staphylinidae) are entirely carnivorous and will catch and comsume small prey such as earthworms and snails. Decaying organic matter is a primary diet for many species, this can range from dung which is consumed by coprophagous species such as the scarab beetles (family Scarabaeidae), to dead animals which are eaten by necrophagous species such as the carrion beetles (family Silphidae). The beneficial impact to the general ecology of these two activities is huge. Various techniques are employed by many species for retaining both air and water supplies. Predaceous diving beetles (family Dytiscidae) may be the most common example, they employ a technique of retaining air when diving between the abdomen and the elytra.

Reproduction

The larval period of beetles varies between species but can be as long as several years. Adults have an extremely variable lifespan, again, from weeks to years. Beetles may display some extremely intricate behaviour when mating. Smell is thought to play significant importance in the location of a mate. Conflict can play a part in the mating rituals for example in species such as burying beetles (genus Nicrophorus) where localised conflicts between males and females rage until only one of each is left, thus ensuring reproduction by the strongest and fittest. Many beetles are territorial and will fiercly defend their small patch of territory from intruding males. Pairing is generally short but in some cases will last for several hours. During pairing sperm cells are transferred to the female to fertilise the egg.

Parental care

As befitting such a large order, the parental care between species varies widely. It ranges from the simple laying of eggs under a leaf to scarab beetles, which construct impressive underground structures complete with a supply of dung to house and feed their young. There are other notable ways of caring for the eggs and young, such as those employed by leaf rollers, who bite sections of leaf causing it to curl inwards and then lay the eggs, thus protected, inside. Generally the number of eggs laid is an indicator of the level of parental care subsequently employed, as they are inversely proportional.

Predation

Beetles and larvae have evolved to employ a variety of different strategies for avoiding being eaten. Many employ simple camoflage to avoid being spotted by predators. These include the leaf beetles (family Chysomelidae) that have a green colouring very similair to their habitat on tree leaves. A number of longhorn beetles (family Cerambycidae) bear a striking resemblance to wasps, thus benefitting from a measure of protection. Large ground beetles by contrast will tend to go on the attack, using their strong mandibles to forcibly persuade a predator to seek out easier prey. Many species, including lady beetles and blister beetles, can secrete poisonous substances to make them unpalatable.

Evolutionary history and classification

Beetles entered the fossil record during the Lower Permian, about 265 million years ago. The four extant suborders of beetle are these:
- Polyphaga is the largest suborder, containing more than 300,000 described species in more than 170 families, including rove beetles (Staphylinidae), scarab beetles (Scarabaeidae), blister beetles (Meloidae), stag beetles (Lucanidae), and true weevils (Curculionidae). These beetles can be identified by the cervical sclerites (hardened parts of the head used as points of attachment for muscles) absent in the other suborders.
- Adephaga contains about 10 families of predatory beetles, includes ground beetles (Carabidae), predacious diving beetles (Dytiscidae) and whirligig beetles (Gyrinidae). In these beetles the testes are tubular and the first abdominal sternum (a plate of the exoskeleton) is divided by the hind coxae (the basal joints of the beetle's legs).
- Archostemata contains four families of mainly wood-eating beetles, including reticulated beetles (Cupedidae) and telephone-pole beetles (Micromalthidae).
- Myxophaga contains about 100 described species in four families, mostly very small, including skiff beetles (Hydroscaphidae) and minute bog beetles (Sphaeriusidae). These suborders diverged in the Permian and Triassic. Their phylogenetic relationship is uncertain, with the most popular hypothesis being that Polyphaga and Myxophaga are most closely related, with Adephaga an outgroup to those two, and Archostemata an outgroup to the other three. The extraordinary number of beetle species poses special problems for classification, with some families consisting of thousands of species and needing further division into subfamilies and tribes. See the article subgroups of the order Coleoptera for a complete list of families.

Impact on humans

Pests

subgroups of the order Coleoptera There are several serious agricultural and household pests represented by the order, these include :
- The Colorado potato beetle (Leptinotarsa decemlineata) is a notorious pest of potato plants. Adults mate before overwintering deep in the soil, so that when they emerge the following spring, females can lay eggs immediately, once a suitable host plant has been found. As well as potatoes, this can be any one of a number of plants from the potato family (Solanaceae) such as nightshade, tomato, aubergine and capsicum. Crops are destroyed and the beetle can only be treated by employing expensive pesticides, many of which it has begun to develop immunity to.
- The elm bark beetles, Hylurgopinus rufipes and Scolytus multistriatus (in the family Scolytidae) attack elm trees. They are important elm pests because they carry Dutch elm disease (the fungus Ophiostoma ulmi) as they move from infected breeding sites to feed on healthy elm trees. The spread of the fungus by the beetle has led to the devastastation of elm trees in many parts of the Northern Hemisphere, notably North America and Europe.
- The death watch beetle (Xestobium rufovillosum) is of some considerable importance as a pest of wooden structures in older buildings in Britain. It attacks hardwoods such as oak and chestnut, and always where some fungal decay has taken or is taking place. It is most usual for death watch beetle attacks to originate in timber of large dimensions, and it is thought that the actual introduction of the pest into buildings takes place at the time of construction.
- Asian long-horned beetle
- Citrus long-horned beetle

Beneficial organisms


- The larvae of lady beetles (family Coccinellidae) are often found in aphid colonies. While both adult and larval lady beetles found on crops prefer aphids, they will, if aphids are scarce, use food from other sources, such as small caterpillars, young plant bugs, aphid honeydew, and plant nectar.
- Large ground beetles (family Carabidae) are predators of caterpillars and, on occasion, adult weevils, whereas smaller species attack eggs, small caterpillars, and other pest insects. Some farmers introduce beetle banks to foster and provide cover for beneficial beetles.

Scarab beetles in Egyptian culture

beetle bank The scarab beetles (family Scarabaeidae) are coprophagous beetles. It seemed to the ancient Egyptians that young scarab beetles emerged spontaneously from the burrow where they were born. Therefore they were worshipped as "Khepri", which means "he who came forth." This creative aspect of the scarab was associated with the creator god Atum. The ray-like antennae on the beetle's head and its practice of dung-rolling caused the beetle to also carry solar symbolism. The scarab beetle god Khepri was believed to push the setting sun along the sky in the same manner as the beetle with his ball of dung. Many thousands of amulets and stamp seals have been excavated that depict the scarab. In many artifacts, the scarab is depicted pushing the sun along its course in the sky. During and following the New Kingdom, scarab amulets were often placed over the heart of the mummified deceased. The amulets were often inscribed with a spell from the Book of the Dead which entreated the heart to, "do not stand as a witness against me." "Le Scarabée Sacré", the opening essay in Jean-Henri Fabre's famous Souvenirs Entomologiques, deals with the insect.

Collecting

Jean-Henri Fabre The study of beetles is called coleopterology, and its practitioners coleopterists. See the list of list of notable coleopterists for more information. There is a thriving industry in the collection of wild caught species for amateur and professional collectors.

North America

North America is a continent in the northern hemisphere bordered on the north by the Arctic Ocean, on the east by the North Atlantic Ocean, on the south by the Caribbean Sea, and on the west by the North Pacific Ocean. It covers an area of 24,497,994 km² (9,458,728 sq mi), or about 4.8% of the Earth's surface. As of July 2002, its population was estimated at more than 514,600,000. It is the third largest continent in area, after Asia and Africa, and is fourth in population after Asia, Africa, and Europe. Both North and South America are named after Amerigo Vespucci, who was the first European to suggest that the Americas were not the East Indies, but a previously undiscovered (by Europeans) New World. North America occupies the northern portion of the landmass generally referred to as the New World, the Western Hemisphere, the Americas, or simply America. North America's only land connection is to South America at the narrow Isthmus of Panama. (For geopolitical reasons, all of Panama – including the segment east of the Panama Canal in the isthmus – is often considered a part of North America alone.) According to some authorities, North America begins not at the Isthmus of Panama but at the Isthmus of Tehuantepec, with the intervening region called Central America and resting on the Caribbean Plate. Most, however, tend to see Central America as a region of North America, considering it too small to be a continent on its own. Greenland, although a part of North America geographically, is not considered to be part of the continent politically.

Physical features

Greenland, plutonic, metamorphic rock types of North America. ]] Plate tectonics recognizes the vast majority of North America as being the surface of the North American Plate. Parts of California and western Mexico are known for being the edge of the Pacific Plate, with the two plates meeting along the San Andreas fault. The continent can be divided into four great regions (each of which contains many sub-regions): the Great Plains stretching from the Gulf of Mexico to the Canadian Arctic; the geologically young, mountainous west, including the Rocky Mountains, the Great Basin, California and Alaska; the raised but relatively flat plateau of the Canadian Shield in the northeast; and the varied eastern region, which includes the Appalachian Mountains, the coastal plain along the Atlantic seaboard, and the Florida peninsula. Mexico, with its long plateaus and cordilleras, falls largely in the western region, although the eastern coastal plain does extend south along the Gulf. The western mountains are split in the middle, into the main range of the Rockies and the coast ranges in California, Oregon, Washington, and British Columbia with the Great Basin – a lower area containing smaller ranges and low-lying deserts – in between. The highest peak is Denali in Alaska. Since 1931, Rugby, North Dakota, has officially been recognized as being at the geographic center of North America. The location is marked by a 4.5 metre (15 foot) field stone obelisk. Image:North america terrain 2003 map.jpg|North America bedrock and terrain.

Territories and regions

craton On the main continent landmass, there are three large and relatively populous countries:
- Canada - many large islands off the shore of North America belong to Canada, including Vancouver Island and the Queen Charlotte Islands on the west, Prince Edward Island, Newfoundland and Cape Breton Island on the east, and the Canadian Arctic islands (including Ellesmere Island, Baffin Island, and Victoria Island) in the north
- Mexico - the Revillagigedo archipelago and numerous smaller islands off its coast belong to Mexico
- The United States - the 48 contiguous states and Alaska are part of North America, while the state of Hawaii in the Pacific Ocean is not; the Aleutian Islands south of Alaska also belong to the U.S. At the southern end of the continent, in a relatively small area known as Central America, are the countries of:
- Belize
- Costa Rica
- El Salvador
- Guatemala
- Honduras
- Nicaragua
- Panama 1 At the southeastern end of the continent lies a chain of islands territories called the Antilles, the Caribbean or the West Indies, which include the countries:
- Antigua and Barbuda
- Bahamas
- Barbados
- Cuba
- Dominica
- Dominican Republic
- Grenada
- Haiti
- Jamaica
- Saint Kitts and Nevis
- Saint Lucia
- Saint Vincent and the Grenadines
- Trinidad and Tobago 1 And the dependencies:
- Anguilla (British overseas territory)
- Aruba 2 (part of the Kingdom of the Netherlands)
- Cayman Islands (British overseas territory)
- Guadeloupe (French région d'outre-mer)
- Martinique (French région d'outre-mer)
- Montserrat (British overseas territory)
- Navassa Island (U.S. territory)
- Netherlands Antilles 1 (part of the Kingdom of the Netherlands)
- Puerto Rico (U.S. commonwealth)
- Turks and Caicos Islands (British overseas territory)
- British Virgin Islands (British overseas territory)
- U.S. Virgin Islands (territory of the USA) Lying in the Atlantic Ocean but considered part of the continent are the dependencies:
- Bermuda, a British overseas territory found about 1,072 km (670 mi.) southeast of New York City
- Greenland, the largest island in the world and a self-governing dependency of Denmark, which is located in the far north of the continent to the east of Nunavut.
- Saint Pierre and Miquelon, a French collectivité d'outre-mer off the south coast of Newfoundland, is the last of France's once vast possessions in America north of the Caribbean. 1 These states and dependencies have territory both in North and South America.
2 These dependencies lie in South America, but are considered North American because of cultural and historical reasons.
See here for details.

Usage

The United States, Canada, and the other English-speaking nations of the Americas (Belize, Guyana, and the Anglophone Caribbean) are sometimes grouped under the term Anglo-America, while the remaining nations of North and South America are grouped under the term Latin America. Alternatively, Northern America is used to refer to Canada and the U.S. together (plus Greenland and Bermuda), while Central America is mainland North America south of the United States. The West Indies generally include all islands in the Caribbean Sea. In this respect, Latin America generally includes Central America and South America and, sometimes, the West Indies. The term Middle America is sometimes used to refer to Mexico, Central America, and the Caribbean collectively. The term "North America" may mean different things to different people. The term in common usage is often taken to mean "the United States and Canada, only" by some people of the United States and Canada, excluding Mexico and the countries of Central America, unless the context makes it clear that they are to be included (such as with specific reference to Mexico, when talking about NAFTA). For example, guides to wild flora and fauna published by the National Audubon Society for "North America" frequently include only species found in Canada and the U.S. This may be attributed to the fact that culturally and economically, the U.S. and Canada are more alike to each other than they are to the rest of North America. Mexicans, however, are acutely aware that Mexico is a part of North America and object to this usage. Central Americans, however, are generally content to be called Central Americans – largely because of their shared history, which includes several attempts at supranational integration in the region and in which Mexico, their much larger northern neighbor, was never involved.

Political divisions and regions

Notes:
1 Continental regions as per UN categorisations/map.
2 Depending on definitions, Aruba, Netherlands Antilles, Panama, and Trinidad and Tobago have territory in one or both of North and South America.
3 Due to ongoing activity of the Soufriere Hills volcano beginning 1995, much of Plymouth, Montserrat's de jure capital, was destroyed and government offices relocated to Brades.

Chile

The Republic of Chile is a country in South America occupying a long coastal strip between the Andes mountains and the Pacific Ocean. It shares borders with Argentina to the east, Bolivia to the northeast and Peru to the north.

Origin of the name

There are various theories about the origin of the word Chile. According to one theory the Incas of Peru, who had failed to conquer the Araucanians, called the valley of the Aconcagua "Chili" by corruption of the name of a tribal chief ("cacique") called Tili, who ruled the area at the time of the Incan conquest. Another theory points to the similarity of the valley of the Aconcagua with that of the Casma in Peru, where there was a town and valley named Chili. Other theories say Chile may derive its name from the indigenous Mapuche word chilli, which may mean "where the land ends" or "the deepest point of the Earth," or from the Aymara tchili meaning "snow"; another meaning attributed to chilli is the onomatopoeic cheele-cheele—the Mapuche imitation of a bird call. The Spanish conquistadors heard about this name from the Incas and the few survivors of Diego de Almagro's first Spanish expedition south from Peru in 1535-36 called themselves the "men of Chilli."

History

About 10,000 years ago, migrating Native Americans settled in fertile valleys and along the coast of what is now Chile. The Incas briefly extended their empire into what is now northern Chile, but the area's remoteness and the fierce opposition of the native population prevented extensive settlement. Inca In 1520, while attempting to circumnavigate the earth, the Portuguese Ferdinand Magellan, discovered the southern passage now named after him, the Straits of Magellan. The next Europeans to reach Chile were Diego de Almagro and his band of Spanish conquistadors, who came from Peru in 1535 seeking gold but were turned back by the local population. The Spanish encountered hundreds of thousands of Indians from various cultures in the area that modern Chile now occupies. These cultures supported themselves principally through slash-and-burn agriculture and hunting. The first permanent European settlement, Santiago, was founded in 1541 by Pedro de Valdivia, one of Francisco Pizarro's lieutenants. Although the Spanish did not find the extensive gold and silver they sought, they recognized the agricultural potential of Chile's central valley, and Chile became part of the Viceroyalty of Peru. Conquest of the land that is today called Chile took place only gradually, and the Europeans suffered repeated setbacks at the hands of the local population. A massive Mapuche insurrection that began in 1553 resulted in Valdivia's death and the destruction of many of the colony's principal settlements. Subsequent major insurrections took place in 1598 and in 1655. Each time the Mapuche and other native groups revolted, the southern border of the colony was driven northward. The abolition of slavery in 1683 defused tensions on the frontier between the colony and the Mapuche land to the south, and permitted increased trade between colonists and Mapuches. The drive for independence from Spain was precipitated by usurpation of the Spanish throne by Napoleon's brother Joseph, in 1808. A national junta in the name of Ferdinand—heir to the deposed king—was formed on September 18, 1810. The junta proclaimed Chile an autonomous republic within the Spanish monarchy. A movement for total independence soon won a wide following. Spanish attempts to reimpose arbitrary rule during what was called the Reconquista led to a prolonged struggle. monarchy Intermittent warfare continued until 1817, when an army led by Bernardo O'Higgins, Chile's most renowned patriot, and José de San Martín, hero of Argentine independence, crossed the Andes into Chile and defeated the royalists. On February 12, 1818, Chile was proclaimed an independent republic under O'Higgins' leadership. The political revolt brought little social change, however, and 19th century Chilean society preserved the essence of the stratified colonial social structure, which was greatly influenced by family politics and the Roman Catholic Church. The system of presidential absolutism eventually predominated, but wealthy landowners continued to control Chile. Toward the end of the 19th century, the government in Santiago consolidated its position in the south by ruthlessly suppressing the Mapuche Indians, finally completing the conquest begun more than three centuries earlier. In 1881, the government signed a treaty with Argentina confirming Chilean sovereignty over the Strait of Magellan. As a result of the War of the Pacific with Peru and Bolivia (1879-83), Chile expanded its territory northward by almost one-third, eliminating Bolivia's access to the Pacific, and acquired valuable nitrate deposits, the exploitation of which led to an era of national affluence. The Chilean Civil War in 1891 brought about a redistribution of power between the President and Congress, and Chile established a parliamentary style democracy. However, the Civil War had also been a contest between those who favored the development of local industries and powerful Chilean banking interests, particularly the House of Edwards who had strong ties to foreign investors. Hence the Chilean economy partially degenerated into a system protecting the interests of a ruling oligarchy. By the 1920s, the emerging middle and working classes were powerful enough to elect a reformist president, Arturo Alessandri Palma, whose program was frustrated by a conservative congress. Alessandri Palma's reformist tendencies were partly tempered later by an admiration for some elements of Mussolini's Italian Corporate State. In the 1920s, Marxist groups with strong popular support arose. A military coup led by General Luis Altamirano in 1924 set off a period of great political instability that lasted until 1932. The longest lasting of the ten governments between those years was that of General Carlos Ibáñez, who briefly held power in 1925 and then again between 1927 and 1931 in what was a de facto dictatorship, although not really comparable in harshness or corruption to the type of military dictatorship that has often bedeviled the rest of Latin America, and certainly not comparable to the violent and repressive regime of Augusto Pinochet decades later. By relinquishing power to a democratically elected successor, Ibáñez del Campo retained the respect of a large enough segment of the population to remain a viable politician for more than thirty years, in spite of the vague and shifting nature of his ideology. When constitutional rule was restored in 1932, a strong middle-class party, the Radicals, emerged. It became the key force in coalition governments for the next 20 years. During the period of Radical Party dominance (1932-52), the state increased its role in the economy. In 1952, voters returned Ibáñez, now reincarnated as a sort of Chilean Perón, to office for another 6 years. Jorge Alessandri succeeded Ibáñez in 1958, bringing Chilean conservatism back into power democratically for another term. The 1964 presidential election of Christian Democrat Eduardo Frei Montalva by an absolute majority initiated a period of major reform. Under the slogan "Revolution in Liberty," the Frei administration embarked on far-reaching social and economic programs, particularly in education, housing, and agrarian reform, including rural unionization of agricultural workers. By 1967, however, Frei encountered increasing opposition from leftists, who charged that his reforms were inadequate, and from conservatives, who found them excessive. At the end of his term, Frei had accomplished many noteworthy objectives, but he had not fully achieved his party's ambitious goals. In 1970, Senator Salvador Allende Gossens, a Marxist physician and member of Chile's Socialist Party, who headed the "Popular Unity" (UP or "Unidad Popular") coalition of the Socialist, Communist, Radical, and Social-Democratic Parties, along with dissident Christian Democrats, the Popular Unitary Action Movement (MAPU), and the Independent Popular Action, won a plurality of votes in a three-way contest. Despite pressure from the government of the United States, the Chilean Congress, keeping with tradition, conducted a runoff vote between the leading candidates, Allende and former president Jorge Alessandri and chose Allende by a vote of 153 to 35. Frei refused to form an alliance with Alessandri to oppose Allende, on the grounds that the Christian Democrats were a workers party and could not make common cause with the oligarchs. Allende's program included advancement of workers' interests; a thoroughgoing implementation of agrarian reform; the reorganization of the national economy into socialized, mixed, and private sectors; a foreign policy of "international solidarity" and national independence; and a new institutional order (the "people's state" or "poder popular"), including the institution of a unicameral congress. The Popular Unity platform also called for nationalization of foreign (U.S.) ownership of Chile's major copper mines. An economic depression that began in 1967 peaked in 1970, exacerbated by capital flight, plummeting private investment, and withdrawal of bank deposits by those opposed to Allende's socialist program. Production fell and unemployment rose. Allende adopted measures including price freezes, wage increases, and tax reforms, which had the effect of increasing consumer spending and redistributing income downward. Joint public-private public works projects helped reduce unemployment. Much of the banking sector was nationalized. Many enterprises within the copper, coal, iron, nitrate, and steel industries were expropriated, nationalized, or subjected to state intervention. Industrial output increased sharply and unemployment fell during the Allende administration's first year. Other reforms undertaken during the early Allende period included redistribution of millions of hectares of land to landless agricultural workers as part of the agrarian reform program, giving the armed forces an overdue pay increase, and providing free milk to children. The Indian Peoples Development Corporation and the Mapuche Vocational Institute were founded to address the needs of Chile's indigenous population. The nationalization of U.S. and other foreign-owned companies led to increased tensions with the United States. The Nixon administration brought international financial pressure to bear in order to restrict economic credit to Chile. Simultaneously, the CIA funded opposition media, politicians, and organizations, helping to accelerate a campaign of domestic destabilization. Interestingly, a CIA plan to buy the cooperation of Chilean members of Congress failed due to the shortage of sufficiently corruptible representatives. By 1972, the economic progress of Allende's first year had been reversed and the economy was in crisis. Political polarization increased, and large mobilizations of both pro- and anti-government groups became frequent, often leading to clashes. By early 1973, inflation was out of control. The crippled economy was further battered by prolonged and sometimes simultaneous strikes by physicians, teachers, students, truck owners, copper workers, and the small business class. A military coup supported by the CIA overthrew Allende on September 11, 1973. As the armed forces bombarded the presidential palace (Palacio de La Moneda), Allende reportedly committed suicide. A military government, led by General Augusto Pinochet Ugarte, took over control of the country. The first years of the regime were marked by serious human rights violations. On October 1973, at least 70 persons were murdered by the Caravan of Death. At least a thousand people were executed during the first six months of Pinochet in office, and at least two thousand more were killed during the next sixteen years, as reported by the Valech Report. Some 30,000 were forced to flee the country. A new Constitution was approved by a highly irregular and undemocratic plebiscite characterized by the absence of registration lists, on September 11, 1980, and General Pinochet became President of the Republic for an 8-year term. In the late 1980s, the regime gradually permitted greater freedom of assembly, speech, and association, to include trade union and limited political activity. The right-wing military government pursued decidedly laissez-faire economic policies. During its nearly 17 years in power, Chile moved away from economic statism toward a largely free market economy that fostered an increase in domestic and foreign private investment, although the copper industry and other important mineral resources were not returned to foreign ownership. In a plebiscite on October 5, 1988, General Pinochet was denied a second 8-year term as president. Chileans elected a new president and the majority of members of a two-chamber congress on December 14, 1989. Christian Democrat Patricio Aylwin, the candidate of a coalition of 16 political parties called the Concertación, received an absolute majority of votes. President Aylwin served from 1990 to 1994. In December 1993, Christian Democrat Eduardo Frei Ruiz-Tagle, the son of previous president Eduardo Frei Montalva, led the Concertación coalition to victory with an absolute majority of votes. President Frei's administration was inaugurated in March 1994. A presidential election was held on December 12, 1999, but none of the six candidates obtained a majority, which led to an unprecedented runoff election on January 16, 2000. Ricardo Lagos Escobar of the Socialist Party led the Concertación coalition to a narrow victory, with 51.31% of the votes. He was sworn in March 11, 2000, for a 6-year term.

Politics

Chile's Constitution was approved in a tightly controlled national plebiscite in September 1980, under the military government of Augusto Pinochet. It entered into force in March 1981. After Pinochet's defeat in the 1988 plebiscite, the Constitution was amended to ease provisions for future amendments to the Constitution. In 2005 over 50 reforms were approved, which eliminated the remaining undemocratic areas of the text, such as the existence of non-elected Senators (institutional senators, or senators for life) and the inability of the President to remove the Commander in Chief of the Armed Forces. These reforms led the President to controversially declare Chile's transition to democracy as complete. Chile's bicameral Congress has a 48-seat Senate—38 elected, 9 appointed, 1 for life—and a 120-member Chamber of Deputies. Deputies are elected every 4 years. Senators serve for 8 years with staggered terms. The current Senate is evenly split 24-24 between pro-government and opposition Senators. Nine institutional senators were appointed in 1999, and two "senators for life," former Presidents Pinochet (who resigned in 2002) and Frei. (Chile's Constitution provided that former presidents who have served at least 6 years shall be entitled to a lifetime senate seat.) The last congressional elections were held in December 2001. The current lower house—the Chamber of Deputies—contains 60 members of the governing center-left coalition and 56 from the center-right opposition. Currently 4 Deputies have their voting rights suspended on legal grounds. The Congress is located in the port city of Valparaíso, about 140 kilometers (84 mi.) west of the capital, Santiago. Chile's congressional elections are governed by a unique binomial system that rewards coalition slates. Each coalition can run two candidates for the two Senate and two lower chamber seats apportioned to each chamber's electoral districts. Typically, the two largest coalitions split the seats in a district. Only if the leading coalition ticket out-polls the second-place coalition by a margin of more than 2-to-1 does the winning coalition gain both seats. In the 2001 congressional elections, the conservative Independent Democratic Union surpassed the Christian Democrats for the first time to become the largest party in the lower house. The Communist Party again failed to gain any seats in the 2001 elections. The next presidential and congressional elections are set for December 2005. (See Chilean presidential election, 2005.) Chile's judiciary is independent and includes a court of appeal, a system of military courts, a constitutional tribunal, and the Supreme Court. Chile will complete in mid-2005 a multi-year overhaul of its criminal justice system. The reform has replaced inquisitorial proceedings with an adversarial system more similar to that of the United States.

Regions

Chile is divided into 13 regions, each of which is headed by an intendente. Every region is further divided into provinces with a Gobernador Provincial. Finally each province is divided into various Comunas each with its own mayor. Intendentes and gobernadores are appointed by the president, mayors are elected by popular vote. Each region is designated by a name and a Roman numeral. Numbers are assigned from north to south. In general the Roman numeral is used, rather than the name. The only exception is the region where Santiago is situated, which is designated RM, that stands for Región Metropolitana, Metropolitan Region.

Geography

Roman numeral Roman numeral A long and narrow coastal region on the west side of the Andes Mountains, Chile stretches over 4,630 km (2,880 miles) north to south, but only 430 km (265 mi) at its widest point east to west. The northern Atacama desert contains great mineral wealth, primarily copper and nitrates. The relatively small Central Valley, which includes Santiago, dominates the country in terms of population and agricultural resources. This area also is the historical center from which Chile expanded in the late 19th century, when it integrated the northern and southern regions. Southern Chile is rich in forests and grazing lands and features a string of volcanoes and lakes. The southern coast is a labyrinth of fjords, inlets, canals, twisting peninsulas, and islands. The Andes Mountains are located on the eastern border. Chile is the longest (N-S) country in the world (over 4,200km), and also claims a large section of Antarctica as part of its territory. Chile controls Easter Island, the easternmost island of Polynesia, which it incorporated to its territory in 1888, and Robinson Crusoe Island, more than 600 km from the mainland, in the Juan Fernández archipelago.

Economy

Juan Fernández After a decade of impressive growth rates, Chile experienced a moderate downturn in 1999 brought on by the global economic slowdown. The economy remained sluggish until 2003, when it began to show clear signs of recovery, achieving 3.3% real GDP growth. The Chilean economy finished 2004 with growth of 6.1%. Most experts expect GDP growth of around 6% in 2005. Chile has pursued generally sound economic policies for nearly three decades. The 1973-90 military government sold many state-owned companies, and the three democratic governments since 1990 have continued privatization at a slower pace. The government's role in the economy is mostly limited to regulation, although the state continues to operate copper giant Codelco and a few other enterprises. Chile is strongly committed to free trade and has welcomed large amounts of foreign investment. Chile has signed Free Trade agreements (FTAs) with several important economies, including an FTA with the United States, which was signed in 2003 and implemented in January 2004. High domestic savings and investment rates also helped propel Chile's economy to average growth rates of 8% during the 1990s. The privatized national pension system has encouraged domestic investment and contributed to an estimated total domestic savings rate of approximately 21% of GDP in 2003. Unemployment has hovered in the 8%-10% range in recent years, well above the 5%-6% average for the 1990s. Unemployment remained at 8.8% at the end of 2004 in spite of strong economic growth. Wages have risen faster than inflation as a result of higher productivity, boosting national living standards. The share of Chileans with incomes below the poverty line--defined as twice the cost of satisfying a person's minimal nutritional needs--fell from 46% of the population in 1987 to 18.8% in 2003. Chile's independent Central bank pursues a policy of maintaining inflation between 2% and 4%. Inflation has not exceeded 5% since 1998. Chile registered inflation of 2.4% in 2004 and is expected to see a 2.5% increase in 2005. Most wage settlements and spending decisions are indexed, reducing inflation's volatility. Under the compulsory private pension system, most formal sector employees pay 10% of their salaries into privately managed funds. Total foreign direct investment rose to $7.1 billion in 2004, up from $2.5 billion in 2003. Both foreign and domestic investment in Chile had declined during the country’s period of slower economic growth from 1999-2003, but appear to be recovering strongly. The Chilean Government committed, in early 2002, to undertake a series of microeconomic reforms designed to create new incentives for private investment. The government also has encouraged the use of Chile as an "investment platform" for multinational corporations planning to invest in the region. Chile's welcoming attitude toward foreign direct investment is codified in the country's Foreign Investment Law, which gives foreign investors the same treatment as Chileans. Registration is simple and transparent, and foreign investors are guaranteed access to the official foreign exchange market to repatriate their profits and capital. The U.S.-Chile Free Trade Agreement offers a number of other investor protections.

Foreign Trade

Chile's economy is highly dependent on international trade. In 2004, exports accounted for about 34% of GDP. Chile has traditionally been dependent upon copper exports; the state-owned firm Codelco is the world's largest copper-producing company. Nontraditional exports have grown faster than those of copper and other minerals. In 1975, non-mineral exports made up just over 30% of total exports, whereas now they account for about 60%. The most important non-mineral exports are forestry and wood products, fresh fruit and processed food, fishmeal and seafood, and wine. The trade balance for 2004 showed a historic surplus $9 billion, considerably higher than 2003. Total exports in 2004 were $32 billion, a 52.1% increase from $20.4 billion in 2003. Chile's export markets are fairly balanced among Europe (25.1%), Asia (33.1%), Latin America (15.7%), and North America (19%). The U.S., the largest national market, takes in 17.3% of Chile's exports. Asia has been the fastest-growing export market in recent years. Chilean imports increased 30% in 2004, to $23 billion, reflecting a positive change in consumer demand and economic recovery. Capital goods made up about 66% of total imports. The United States represented 14.6% of Chilean imports in 2004. As a bloc, the European Union (EU) in 2004 supplied 16.3% of Chile's imports, while Argentina contributed 16%. Chile unilaterally lowered its across-the-board import tariff for all countries with which it does not have a trade agreement to 6% in 2003. Higher effective tariffs are charged only on imports of wheat, wheat flour, and sugar as a result of a system of import price bands. The price bands were ruled inconsistent with Chile's WTO obligations in 2002 and the government has introduced legislation to modify them. Chile will have to phase out the price bands within 12 years under the terms of the U.S.-Chile FTA. Successive Chilean governments have actively pursued liberalizing trade agreements. During the 1990s, Chile signed FTAs with Canada, Mexico, and Central America. Chile also concluded preferential trade agreements with Venezuela, Colombia, and Ecuador. An association agreement with Mercosur--Argentina, Brazil, Paraguay, and Uruguay--went into effect in October 1996. Chile, a member of the Asia-Pacific Economic Cooperation (APEC) organization, is seeking to boost commercial ties to Asian markets. Continuing its export-oriented development strategy, Chile completed landmark free trade agreements in 2002 with the European Union and South Korea. After two years of negotiations, the United States and Chile signed an agreement in June 2003. The agreement will lead to completely duty free bilateral trade within 12 years. The U.S.-Chile FTA entered into force January 1, 2004 following approval by the U.S and Chilean congresses. Chile is a strong proponent of pressing ahead on negotiations for a Free Trade Area of the Americas (FTAA). Chile also has signed trade agreements with China, as well as a four -partite agreement with Singapore, New Zealand and the Kingdom of Brunei Darussalam (P4). Currently it is negotiating with India.

Finance

Chile's financial sector has grown faster than other areas of the economy over the last few years; a banking reform law approved in 1997 broadened the scope of permissible foreign activity for Chilean banks. The Chilean government implemented a further liberalization of capital markets in 2001. Chileans have enjoyed the recent introduction of new financial tools such as home equity loans, currency futures and options, factoring, leasing, and debit cards. The introduction of these new products has been accompanied by increased use of traditional instruments such as loans and credit cards. Chile's private pension system, with assets worth roughly $54 billion in late 2004, has provided an important source of investment capital for the capital market. Chile maintains one of the best credit ratings (Standard & Poor's A+) of countries in Latin America. There are three main ways Chilean firms raise funds abroad: bank loans, bond issue, and the selling of stock on U.S. markets through American Depository Receipts (ADR's). Nearly all of the funds raised go to finance investment. The government is paying off its foreign debt. The combined public and private foreign debt was roughly over 50% of GDP at the end of 2004—low by Latin American standards.

Defense

Standard & Poor's Chile's Armed Forces are subject to civilian control exercised by the President through the Minister of Defense. Under the 1980 Constitution, the services enjoyed considerable autonomy, and the President could not remove service commanders on his own authority. However, reforms made in 2005 to the Constitution now give the President the right to remove the Commanders in Chief of the Armed Forces.

Army

The commander in chief of the Chilean Army is Maj. Gen. Juan Emilio Cheyre. The Chilean Army is 45,000 strong and is organized with an Army headquarters in Santiago, seven divisions throughout its territory, an Air Brigade in Rancagua, and a Special Forces Command in Colina. The Chilean Army is one of the most professional armies in the world and has one of the most technologically advanced armies in Latin America. It also operates Leopard I and AMX-30 main battle tanks.

Navy

Adm. Rodolfo Codina Díaz directs the 25,000-person Navy, including 5,000 Marines. Of the fleet of 29 surface vessels, only six are operational major combatants (destroyers and frigates). Those ships are based in Valparaíso. The Navy operates its own aircraft for transport and patrol; there are no Navy fighter or bomber aircraft. The Navy also operates three submarines based in Talcahuano.

Air Force (FACH)

Gen. Osvaldo Sarabia heads a force of 12,500. Air assets are distributed among five air brigades headquartered in Iquique, Antofagasta, Santiago, Puerto Montt, and Punta Arenas. The Air Force also operates an airbase on King George Island, Antarctica. The FACH will begin taking delivery of 10 U.S. F-16 aircraft in 2006.

Carabineros

After the military coup in September 1973, the Chilean national police (Carabineros) were incorporated into the Defense Ministry. With the return of democratic government, the police were placed under the operational control of the Interior Ministry but remained under the nominal control of the Defense Ministry. Gen. Alberto Cienfuegos is the head of the national police force of 30,000 men and women who are responsible for law enforcement, traffic management, narcotics suppression, border control, and counter-terrorism throughout Chile.

Foreign relations

Since its return to democracy in 1990, Chile has been an active participant in the international political arena. Chile completed a 2-year non-permanent position on the UN Security Council in January 2005. Chile is an active member of the UN family of agencies and participates in UN peacekeeping activities. Chile hosted the Defense Ministerial of the Americas in 2002 and the APEC summit and related meetings in 2004. Chile hosted the Community of Democracies ministerial in April 2005. An associate member of Mercosur and a full member of APEC, Chile and has been an important actor on international economic issues and hemispheric free trade. The Chilean Government has diplomatic relations with most countries. It settled its territorial disputes with Argentina during the 1990s. Chile and Bolivia severed diplomatic ties in 1978 over Bolivia's desire to reacquire territory it lost to Chile in 1879-83 War of the Pacific. The two countries maintain consular relations.

Demographics

War of the Pacific Unlike some of its South American neighbours, Chile is a relatively homogenous country. Around 95% of Chileans descend from early Spanish colonists, with the overwhelming part also possessing Native American ancestry in varying degrees - thus deeming the population majority as mestizo. During the colonial period, Spain found it necessary to maintain a continual influx of soldiers to protect its distant American colonies. Spaniards arrived from all regions of Spain, including: Andalucia, Extremadura and the Basque country, and many of them ended up settling in Chile. The combination of an economy based on temperate-zone agriculture, Amerindian resistance to Spanish occupation, and a continuous influx of Spaniards from the mid-sixteenth century to the end of the colonial period defined the main body of Chile's mestizo majority population to one where the average Spanish input is greater than in neighbouring Andean mestizo populations. People of relatively unmixed Spanish ancestry are not uncommon. Those of unmixed European ancestry are estimated between 5 to 10 percent. People that self-identify solely as members of any of the country's many indigenous groups number around 700,000 individuals, or 5% of the country's total population. Of that 700,000, around 80% are Mapuche that reside mainly in the south-central area of the country. Aymara and Quechua-speaking populations live along the northern border with Peru and Bolivia. There are also around 5,000 polynesian people who are indigenous to the Chilean territory of Easter Island (Rapanui) in the Pacific. Chileans descended from non-Spanish European nationalities are not very numerous, and they include a small but influential number of descendants of Irish immigrants which arrived in Chile during the Spanish colonial period, descendants of English immigrants (mainly merchants and sailors). A small scale government-sponsored immigration from Germany began in 1848, and in time, changed the cultural makeup of the southern provinces of Valdivia, Llanquihue, and Osorno, which still show a strong German influence. Other historically significant immigrant groups include people of Italian ancestry (Valparaíso Region) , Croatian (Antofagasta and Punta Arenas), French, Polish and peoples from Middle Eastern backgrounds (including the second largest Palestinian colony outside of the Middle East). In the last decade there has been an influx of Koreans who settled in small sections of Santiago. In recent years, the difficult economic situation in neighbouring Peru and Argentina has resulted in work-related trans-Andean migration to Chile.

Culture

Northern Chile was an important center of culture in the medieval and early modern Inca empire. Afterwards, their culture was dominated by the Spanish during the Colonial and early Republican period. Other European influences, primarily English and French, began in the 19th century and have continued until today, as in other Western societies. The national dance is the cueca. Another form of traditional Chilean song, though not a dance, is the tonada. Arising from music imported by the Spanish colonists, it is distinguished from the cueca by an intermediate melodic section and a more prominent melody. In the mid-1960s native musical forms were revitalized by the Parra family with the Nueva Canción Chilena, which was associated with political activists and reformers. Chileans call their country País de Poetas which means land of poets.

National symbols

Nueva Canción Chilena The national flower is the copihue (Lapageria rosea, Chilean bellflower), which grows in the woods of southern Chile. copihue The coat of arms depicts the two national animals: the condor (Vultur gryphus, a very large bird that lives in the mountains) and the huemul (Hippocamelus bisulcus, an endangered white tail deer). It also has the legend Por la razón o la fuerza (By right or might or By reason or by force).

Vojnovskyales †
Voltziales † The conifers, division Pinophyta, are one of 13 or 14 division level taxa within the Kingdom Plantae. They are cone-bearing seed plants with vascular tissue; all extant conifers are woody plants, the great majority being trees with just a few being shrubs. Typical examples of conifers include cedars, cypresses, douglas-firs, firs, junipers, kauris, larches, pines, redwoods, spruces, and yews. Species of conifers can be found growing naturally in almost all parts of the world, and are frequently dominant plants in their habitats, as in e.g. the taiga. Conifers are of immense economic value, primarily for timber and paper production; the wood of conifers is known as softwood.

Taxonomy and naming

The division name Pinophyta conforms with the rules of the ICBN, which state (Art 16.1) that the names of higher taxa in plants (above the rank of family) are either based on the name of the type genus, in this case, Pinus (pines), or are descriptive. In the latter case the name for the conifers is Coniferae (Art 16 Ex 2), which is in widespread use as well. Older scientific names (no longer allowed) are Coniferophyta and Coniferales. In an older, broader sense of the name, the conifers were often considered equivalent to the Gymnosperms, although this grouping is polyphyletic as it includes distinct, only distantly related plants like the cycads and ginkgos not in the Pinophyta, but excludes the Magnoliophyta (flowering plants), equally or perhaps more closely related. The division contains just one class of living plants, class Pinopsida. Subdivision of the conifers into two or more orders has been proposed from time to time. The most commonly seen in the past was a split into two orders, Taxales (Taxaceae only) and Pinales (the rest), but recent genetic evidence has shown that this interpretation leaves the Pinales without Taxales as polyphyletic, and the latter order is no longer regarded as distinct. A more accurate division would be to split the division into three orders, Pinales containing only Pinaceae, Araucariales containing Araucariaceae and Podocarpaceae, and Cupressales (including Taxales) containing the remaining families, but there has not been any significant support for any division, with the majority of opinion preferring retention of all the families within a single order Pinales, despite their antiquity and diverse morphology. polyphyletic The conifers are now accepted as comprising six to eight families, with a total of 65-70 genera and 600-650 species. The seven most distinct families are linked in the box above right and phylogenetic diagram left. In other interpretations, the Cephalotaxaceae may be better included within the Taxaceae, and some authors additionally recognise Phyllocladaceae as distinct from Podocarpaceae (in which it is included here). A further family Taxodiaceae was widely recognised in the past, but is now normally included within Cupressaceae. The conifers are an ancient group, with a fossil record extending back about 300 million years to the Paleozoic in the late Carboniferous period; even many of the modern genera are recognisable from fossils 60-120 million years old. Other classes and orders, now long extinct, also occur as fossils, particularly from the late Paleozoic and Mesozoic eras. Fossil conifers included many diverse forms, the most dramatically distinct from modern conifers being some herbaceous conifers with no woody stems. Major fossil orders of conifers or conifer-like plants include the Cordaitales, Vojnovskyales, Voltziales and perhaps also the Czekanowskiales (possibly more closely related to the Ginkgophyta).

Morphology

All living conifers are woody plants, and most are trees, the majority having monopodial growth form (a single, straight trunk with side branches). The size of mature conifers varies from less than one metre, to over 100 metres. The world's tallest, largest, thickest and oldest living things are all conifers. The tallest is a Coast Redwood (Sequoia sempervirens), with a height of 112.34 metres. The largest is a Giant Sequoia (Sequoiadendron giganteum), with a volume 1486.9 cubic metres. The thickest, or tree with the greatest trunk diameter, is a Montezuma Cypress (Taxodium mucronatum), 11.42 metres in diameter. The oldest is a Great Basin Bristlecone Pine (Pinus longaeva), 4,700 years old.

Foliage

Great Basin Bristlecone Pine (Pseudotsuga menziesii)]] Great Basin Bristlecone Pine (Chamaecyparis lawsoniana); scale in mm]] The leaves of many conifers are long, thin and needle-like, but others, including most of the Cupressaceae and some of the Podocarpaceae, have flat, triangular scale-like leaves. Some, notably Agathis in Araucariaceae and Nageia in Podocarpaceae, have broad, flat strap-shaped leaves. In the majority of conifers, the leaves are arranged spirally, exceptions being most of Cupressaceae and one genus in Podocarpaceae, where they are arranged in decussate opposite pairs or whorls of 3 (-4). In many species with spirally arranged leaves, the leaf bases are twisted to present the leaves in a flat plane for maximum light capture (see e.g. photo of Grand Fir Abies grandis). Leaf size varies from 2 mm in many scale-leaved species, up to 400 mm long in the needles of some pines (e.g. Apache Pine Pinus engelmannii). The stomata are in lines or patches on the leaves, and can be closed when it is very dry or cold. The leaves are often dark green in colour which may help absorb a maximum of energy from weak sunshine at high latitudes or under forest canopy shade. Conifers from hotter areas with high sunlight levels (e.g. Turkish Pine Pinus brutia) often have yellower-green leaves, while others (e.g. Blue Spruce Picea pungens) have a very strong glaucous wax bloom to reflect ultraviolet light. In the great majority of genera the leaves are evergreen, usually remaining on the plant for several (2-40) years before falling, but three genera (Larix, Taxodium and Metasequoia) are deciduous, shedding the leaves in autumn and leafless through the winter. The seedlings of many conifers, including most of the Cupressaceae, and Pinus in Pinaceae, have a distinct juvenile foliage period where the leaves are different, often markedly so, from the typical adult leaves.

Reproduction

deciduous See conifer cones for a more detailed discussion. Most conifers are monoecious, but some are subdioecious or dioecious; all are wind-pollinated. Conifer seeds develop inside a protective cone called a strobilus (or, very loosely, "pine cones", which technically occur only on pines, not other conifers!). The cones take from four months to three years to reach maturity, and vary in size from 2 mm to 600 mm long. In Pinaceae, Araucariaceae, Sciadopityaceae and most Cupressaceae, the cones are woody, and when mature the scales usually spread open allowing the seeds to fall out and be dispersed by the wind. In some (e.g. firs), the cones disintegrate to release the seeds, and in others (e.g. the pines that produce pine nuts) the nut-like seeds are dispersed by birds (mainly nutcrackers and jays) which break up the specially adapted softer cones. Ripe cones may remain on the plant for a varied amount of time before falling to the ground; in some fire-adapted pines, the seeds may be stored in closed cones for up to 60-80 years, being released only when a fire kills the parent tree. jay In the families Podocarpaceae, Cephalotaxaceae, Taxaceae, and one Cupressaceae genus (Juniperus), the scales are soft, fleshy, sweet and brightly coloured, and are eaten by fruit-eating birds, which then pass the seeds in their droppings. These fleshy scales are (except in Juniperus) known as arils. In some of these conifers (e.g. most Podocarpaceae), the cone consists of several fused scales, while in others (e.g. Taxaceae), the cone is reduced to just one seed scale or (e.g. Cephalotaxaceae) the several scales of a cone develop into individual arils, giving the appearance of a cluster of berries. The male cones have structures called microsporangia which produce yellowish pollen. Pollen is released and carried by the wind to female cones. Pollen grains from living pinophyte species produce pollen tubes, much like those of angiosperms. When a pollen grain lands near a female gametophyte, it undergoes meiosis and fertilizes the female gametophyte. The resulting zygote develops into an embryo, which along with its surrounding integument, becomes a seed. Eventually the seed may fall to the ground and, if conditions permit, grows into a new plant. In forestry, the terminology of flowering plants has commonly though inaccurately been applied to cone-bearing trees as well. The male cone and unfertilized female cone are called "male flower" and "female flower", respectively. After fertilization, the female cone is term "fruit", which undergoes "ripening" (maturation).

Life cycle

# To fertilize the ovum, the male cone releases pollen that is carried on the wind to the female cone. # A fertilized female gamete (called a zygote) develops into an embryo. # Along with integument cells surrounding the embryo, a seed develops containing the embryo. # Mature seed drops out of cone onto the ground. # Seed germinates and seedling grows into a mature plant. # When mature, the adult plant produces cones.

Other facts

seed Although the total number of species is relatively small, conifers are of immense ecological importance. They are the dominant plants over huge areas of land, most notably the boreal forests of the northern hemisphere, but also in similar cool climates in mountains further south. Many conifers have distinctly scented resin, secreted to protect the tree against insect infestation and fungal infection of wounds. Fossilised resin hardens into amber.

Ross H. Arnett, Jr.

Ross Harold Arnett, Jr. (April 13, 1919 - July 16, 1999) was an American entomologist noted for his studies of beetles, and as founder of the Coleopterist's Bulletin. Born in Medina, New York, he was a star student at Cornell University, where he became interested in beetles and started on a revision of the Nearctic Silphidae. He graduated in 1942, the same year that he married his high school sweetheart Mary Ennis. His first job was at the New York State Conservation Department, studying the stomach contents of game birds, but in July 1942 he joined the US Army (as a private) and was sent to Lowry Air Force Base to study the Sperry bombsight. After this diversion into non-insect work, he went to Avon Park Bombing Range in Florida to survey the mosquito population and control it, and from there to the Army School of Malariology in Panama to teach mosquito taxonomy. In October 1945 he was discharged and returned to Cornell for graduate study, where he studied under Robert Matheson and Walter Muenscher, receiving a master's degree in 1946 and the doctorate in 1948, where he returned to beetle work, revising the Oedemeridae. He started the Coleopterist's Bulletin in 1947, while still a grad student. In July 1948, the newly-minted Dr. Arnett moved to Arlington, Virginia and went to work for the USDA as a beetle taxonomist. He returned to academia in 1954 however, as head of the biology department of Saint John Fisher College in Fairview, New York, then to the Catholic University of America in 1958, where he published his best-known work Beetles of the United States (1963). In 1966 Arnett moved to Purdue University, later spending three years as Henry L. Beadel Fellow at the Tall Timbers Research Station near Tallahassee, Florida, and then in 1973 moving to Siena College in Loudonville, New York. In 1979 he resigned his position to write fulltime, publishing several books, then in 1982 founding Flora and Fauna Publications in Gainesville, Florida. The company was bought by E.J. Brill Publishers, but in 1989 they stopped doing biology, and he formed Sandhill Crane Press to continue with his work. He also founded the Center for Systematic Entomology during this time. He died at his home in Gainesville, while working on a new handbook American Beetles, which was published posthumously.

American Beetles

American Beetles is the single most comprehensive description of the beetles of North America north of the tropical area of Mexico. It was started by Ross H. Arnett, Jr. as an update of his classic The Beetles of the United States; along with Michael C. Thomas, he enlisted more than 60 specialists to write treatments of each family. The work outlived Arnett, and was published by
