Cyatta
''Cyatta'' is a genus of ant in the subfamily Myrmicinae containing the single species ''Cyatta abscondita''. It is considered the most recent ancestor of all fungus-farming ants and a living fossil. Etymology ''Cyatta'' is a neologism constructed in part from the Brazilian Tupi language word ''Cy'', meaning "sister," referring to its status, along with the genus '' Kalathomyrmex'', as the sister clade to the remaining genera of the informal clade Neoattini, to which the genus ''Atta'', the most conspicuous member of the Neoattini, belongs. The specific name ''abscondita'' refers to the exceedingly secretive nature of this species, which, after being recognized from a few rare specimens, proved frustratingly elusive during multiple attempts to locate it in the field. Discovery history In 2003, a single stray worker of ''C. abscondita'' was taken in a pitfall trap as part of an ant survey conducted at the Reserva Particular do Patrimônio Natural Serra das Almas, Crateús, Cea ...

Myrmicinae
Myrmicinae is a subfamily of ants, with about 140 extant genera; their distribution is cosmopolitan. The pupae lack cocoons. Some species retain a functional sting. The petioles of Myrmicinae consist of two nodes. The nests are permanent and in soil, rotting wood, under stones, or in trees.Goulet, H & Huber, JT (eds.) (1993) Hymenoptera of the world: an identification guide to families. Agriculture Canada. p. 224 Identification Myrmicine worker ants have a distinct postpetiole, i.e., abdominal segment III is notably smaller than segment IV and set off from it by a well-developed constriction; the pronotum is inflexibly fused to the rest of the mesosoma, such that the promesonotal suture is weakly impressed or absent, and a functional sting is usually present. The clypeus is well-developed; as a result, the antennal sockets are well separated from the anterior margin of the head. Most myrmicine genera possess well-developed eyes and frontal lobes that partly conceal the an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Living Fossil
A living fossil is an extant taxon that cosmetically resembles related species known only from the fossil record. To be considered a living fossil, the fossil species must be old relative to the time of origin of the extant clade. Living fossils commonly are of species-poor lineages, but they need not be. While the body plan of a living fossil remains superficially similar, it is never the same species as the remote relatives it resembles, because genetic drift would inevitably change its chromosomal structure. Living fossils exhibit stasis (also called "bradytely") over geologically long time scales. Popular literature may wrongly claim that a "living fossil" has undergone no significant evolution since fossil times, with practically no molecular evolution or morphological changes. Scientific investigations have repeatedly discredited such claims. The minimal superficial changes to living fossils are mistakenly declared as an absence of evolution, but they are examples of s ...

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...

Atta (genus)
''Atta'' is a genus of New World ants of the subfamily Myrmicinae. It contains at least 17 known species. ''Atta'' leaf-cutter ants are relatively large, rusty red or brown in colour, and have a spiny body and long legs. The three main castes within a nest are the queen, worker, and soldier. Only the queens and males have wings (alate), and these ants are also known as reproductives or swarmers. Although most of the ants in the nest are female, only the queens produce eggs. Queens are usually over long. Overview Ants of the genus ''Atta'' are leafcutter ants that comprise one of the two genera of leafcutting ants within the tribe Attini, along with ''Acromyrmex''. They have no sting, thus inject no venom, although they are known as strong biters. ''Atta'' spp. exhibit a high degree of polymorphism, with four castes being present in established colonies: minims (or garden ants), minors, mediae, and majors (also called soldiers or dinergates). Their immature development underg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Federal District (Brazil)
The Federal District ( pt, Distrito Federal ) is one of 27 federative units of Brazil. Located in the Center-West Region, it is the smallest Brazilian federal unit and the only one that has no municipalities, being divided into 31 administrative regions. The federal capital of Brazil, Brasília, which is also the seat of government of the Federal District, is located in its territory. History From the first republican constitution there was already a device that foresaw the move of the federal capital from Rio de Janeiro, at that time in the former Federal District (1889-1960), to the interior of the country. In 1891 the Exploration Commission of the Central Highlands of Brazil was appointed, led by astronomer Luiz Cruls and composed of doctors, geologists and botanists, who made a study on topography, climate, geology, flora, fauna and other material resources of the region of the Central Highlands The area was known as Quadrilateral Cruls and was presented in 1894 to t ...

Brasília
Brasília (; ) is the federal capital of Brazil and seat of government of the Federal District. The city is located at the top of the Brazilian highlands in the country's Central-West region. It was founded by President Juscelino Kubitschek on 21 April 1960, to serve as the new national capital. Brasília is estimated to be Brazil's third-most populous city. Among major Latin American cities, it has the highest GDP per capita. Brasília was a planned city developed by Lúcio Costa, Oscar Niemeyer and Joaquim Cardozo in 1956 in a scheme to move the capital from Rio de Janeiro to a more central location. The landscape architect was Roberto Burle Marx. The city's design divides it into numbered blocks as well as sectors for specified activities, such as the Hotel Sector, the Banking Sector, and the Embassy Sector. Brasília was inscribed as a UNESCO World Heritage Site in 1987 due to its modernist architecture and uniquely artistic urban planning. It was named "City of ...

Caatinga
Caatinga (, ) is a type of semi-arid tropical vegetation, and an ecoregion characterized by this vegetation in interior northeastern Brazil. The name "Caatinga" is a Tupi word meaning "white forest" or "white vegetation" (''caa'' = forest, vegetation, ''tinga'' = white). The Caatinga is a xeric shrubland and thorn forest, which consists primarily of small, thorny trees that shed their leaves seasonally. Cacti, thick-stemmed plants, thorny brush, and arid-adapted grasses make up the ground layer. Most vegetation experiences a brief burst of activity during the three-month long rainy season. Caatinga falls entirely within earth's tropical zone and is one of 6 major ecoregions of Brazil. It covers 850,000 km², nearly 10% of Brazil's territory. It is home to 26 million people and over 2000 species of plants, fish, reptiles, amphibians, birds, and mammals. The Caatinga is the only exclusively Brazilian biome, which means that a large part of its biological heritage cannot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
