Dinoponera Quadriceps
''Dinoponera quadriceps'' is a queenless species of ants in the subfamily Ponerinae. The species, known from Brazil, is similar to ''Dinoponera mutica'' and uses venom for subduing large live prey and defense. Its venom could be of use to the pharmaceutical industry. Distribution ''Dinoponera quadriceps'' is found in the Caatingas, Cerrados, upland humid forest and Atlantic forest in the northeastern Brazilian states of Alagoas, Bahia, Ceará, Paraiba, Pernambuco and Rio Grande do Norte. Of all ''Dinoponera'', ''Dinoponera quadriceps'' has the largest colonies with an average of 80 workers (range 26–238). ''Dinoponera quadriceps'' usually nest at the base of trees. Observations of ''Dinoponera quadriceps'' nests show that in more arid Caatinga and Cerrado habitats, nests are predominantly constructed under trees, whereas in Atlantic forest 60% of nests were 3 m away from any tree. Nests are deeper in ''Dinoponera quadriceps'' (and ''Dinoponera australis'') than in ''Dinoponer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

States Of Brazil
The federative units of Brazil ( pt, unidades federativas do Brasil) are subnational entities with a certain degree of autonomy (self-government, self-regulation and self-collection) and endowed with their own government and constitution, which together form the Federative Republic of Brazil. There are 26 states (') and one federal district ('). The states are generally based on historical, conventional borders which have developed over time. The states are divided into municipalities A municipality is usually a single administrative division having corporate status and powers of self-government or jurisdiction as granted by national and regional laws to which it is subordinate. The term ''municipality'' may also mean the go ..., while the Federal District (Brazil), Federal District assumes the competences of both a state and a municipality.

Tocantins
Tocantins () is one of the 26 states of Brazil. It is the newest state, formed in 1988 and encompassing what had formerly been the northern two-fifths of the state of Goiás. Tocantins covers and had an estimated population of 1,496,880 in 2014. Construction of its capital, Palmas, began in 1989; most of the other cities in the state date to the Portuguese colonial period. With the exception of Araguaína, there are few other cities with a significant population in the state. The government has invested in a new capital, a major hydropower dam, railroads and related infrastructure to develop this primarily agricultural area. The state has 0.75% of the Brazilian population and is responsible for 0.5% of the Brazilian GDP. Tocantins has attracted hundreds of thousands of new residents, primarily to Palmas. It is building on its hydropower resources. The Araguaia and Tocantins rivers drain the largest watershed that lies entirely inside Brazilian territory. The Rio Tocantins ...

Petiole (insect Anatomy)
In entomology, petiole is the technical term for the narrow waist of some hymenopteran insects, especially ants, bees, and wasps in the suborder Apocrita. The petiole can consist of either one or two segments, a characteristic that separates major subfamilies of ants. Structure The term 'petiole' is most commonly used to refer to the constricted first (and sometimes second) metasomal (posterior) segment of members of the hymenopteran suborder Apocrita (ants, bees, and wasps). It is sometimes also used to refer to other insects with similar body shapes, where the metasomal base is constricted. The petiole is occasionally called a pedicel, but in entomology, that term is more correctly reserved for the second segment of the antenna; while in arachnology, 'pedicel' is the accepted term to define the constriction between the cephalothorax and abdomen of spiders. The plump portion of the abdomen posterior to the petiole (and postpetiole in the Myrmicinae) is called the gaster ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Setae
In biology, setae (singular seta ; from the Latin word for "bristle") are any of a number of different bristle- or hair-like structures on living organisms. Animal setae Protostomes Annelid setae are stiff bristles present on the body. They help, for example, earthworms to attach to the surface and prevent backsliding during peristaltic motion. These hairs make it difficult to pull a worm straight from the ground. Setae in oligochaetes (a group including earthworms) are largely composed of chitin. They are classified according to the limb to which they are attached; for instance, notosetae are attached to notopodia; neurosetae to neuropodia. Crustaceans have mechano- and chemosensory setae. Setae are especially present on the mouthparts of crustaceans and can also be found on grooming limbs. In some cases, setae are modified into scale like structures. Setae on the legs of krill and other small crustaceans help them to gather phytoplankton. It captures them and allows ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pronotum
The prothorax is the foremost of the three segments in the thorax of an insect, and bears the first pair of legs. Its principal sclerites (exoskeletal plates) are the pronotum (dorsal), the prosternum (ventral), and the propleuron (lateral) on each side. The prothorax never bears wings in extant insects (except in some cases of atavism), though some fossil groups possessed wing-like projections. All adult insects possess legs on the prothorax, though in a few groups (e.g., the butterfly family Nymphalidae) the forelegs are greatly reduced. In many groups of insects, the pronotum is reduced in size, but in a few it is hypertrophied, such as in all beetles (Coleoptera). In most treehoppers (family Membracidae, order Hemiptera), the pronotum is expanded into often fantastic shapes that enhance their camouflage or mimicry. Similarly, in the Tetrigidae, the pronotum is extended backward to cover the flight wings, supplanting the function of the tegmina. See also *Glossary of entomolo ...

Dinoponera Australis
''Dinoponera australis'' is a species of ant notable for its lack of distinct queen caste. Subspecies ''Dinoponera australis'' is divided into three subspecies: * ''Dinoponera australis australis'' Emery, 1901 * ''Dinoponera australis bucki'' Borgmeier, 1937 * ''Dinoponera australis nigricolor'' Borgmeier, 1937 Description Studies have shown that fat storage in this species is related to the division of labour in the colony and non-reproductive individuals are characterized with a lower lipid count than reproductives. ''Dinoponera australis'' has been found to exhibit marked differences in the degree of polyploidy across its tissues, ranging from 2 to 64 copies of the nuclear genome. Distribution ''Dinoponera australis'' has the widest known range of the ''Dinoponera''. This species is found in the department of Santa Cruz in Bolivia, southern Brazil in the states of Mato Grosso, Goiás, Minas Gerais, São Paulo, Mato Grosso do Sul, Paraná, Santa Catarina and Rio G ...

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] |
