Oxyepoecus Mandibularis
''Oxyepoecus'' is a Neotropical genus of ant in the subfamily Myrmicinae. The genus is a member of the tribe Solenopsidini and currently includes 20 species. Distribution The genus of is known from the Neotropics, from Colombia to Chile, where it is collected infrequently. Identification ''Oxyepoecus'' is differentiated from other Solenopsidini by the 11-segmented antennae with a three-segmented apical club, the clypeus with four teeth, and the dentate propodeum. In addition, the petiole and postpetiole nodes are high and often anteroposteriorly compressed. Biology The biology of the genus is poorly known, but three species ('' O. inquilinus'', '' O. daguerrei'', and '' O. bruchi'') are suspected to be inquilines of ''Pheidole'' or '' Solenopsis'', although the exact nature of the relationship is unclear. These three species are considered as " Vulnerable D2" by IUCN, meaning they are suspected to be "facing a high risk of extinction in the wild in the medium-term future ...

Paraguay
Paraguay (; ), officially the Republic of Paraguay ( es, República del Paraguay, links=no; gn, Tavakuairetã Paraguái, links=si), is a landlocked country in South America. It is bordered by Argentina to the south and southwest, Brazil to the east and northeast, and Bolivia to the northwest. It has a population of seven million, nearly three million of whom live in the capital and largest city of Asunción, and its surrounding metro. Although one of only two landlocked countries in South America (Bolivia is the other), Paraguay has ports on the Paraguay and Paraná rivers that give exit to the Atlantic Ocean, through the Paraná-Paraguay Waterway. Spanish conquistadores arrived in 1524, and in 1537, they established the city of Asunción, the first capital of the Governorate of the Río de la Plata. During the 17th century, Paraguay was the center of Jesuit missions, where the native Guaraní people were converted to Christianity and introduced to European culture. ...

Propodeum
The propodeum or propodium is the first abdominal segment in Apocrita Hymenoptera (wasps, bees and ants). It is fused with the thorax to form the mesosoma. It is a single large sclerite, not subdivided, and bears a pair of spiracles. It is strongly constricted posteriorly to form the articulation of the petiole, and gives apocritans their distinctive shape. There may be a suture between the propodeum and the thorax, like in Symphyta Sawflies are the insects of the suborder Symphyta within the order Hymenoptera, alongside ants, bees, and wasps. The common name comes from the saw-like appearance of the ovipositor, which the females use to cut into the plants where they lay ... or not, and the presence or absence of such suture can aid in identifying specimens. In molluscs Propodium is the anterior (frontal) part of the foot of a mollusk. References Insect anatomy Gastropod anatomy {{insect-anatomy-stub ...

Oxyepoecus Bidentatus
''Oxyepoecus bidentatus'' is a Neotropical species of ant in the genus '' Oxyepoecus''. The species is only known from workers from Paraguay. Distribution ''Oxyepoecus bidentatus'' is known from three localities of the Paraguayan dry Chaco. Because the maximal distance between localities was 340 km, ''O. bidentatus'' is suspected to be widely distributed in xeromorphic Chacoan forests, even if rarely found. Description Its worker morphology places the species within the ''rastratus'' species-group. ''Oxyepoecus bidentatus'' is the only species of the genus to have both the dorsal surface of the head entirely covered by sculpture and a bidentate subpostpetiolar process. The anterior subpostpetiolar process of '' O. bruchi'' of the ''vezenyii'' species-group is also prominent and bidentate, but the dorsal surface of the head is mainly smooth and shining except for two patches of fine, longitudinal rugulae which do not reach posteriorly to the vertex margin nor laterally to ...

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vulnerable Species
A vulnerable species is a species which has been Conservation status, categorized by the International Union for Conservation of Nature as being threatened species, threatened with extinction unless the circumstances that are threatened species, threatening its survival and reproduction improve. Vulnerability is mainly caused by habitat loss or destruction of the species' home. Vulnerable habitat or species are monitored and can become increasingly threatened. Some species listed as "vulnerable" may be common in captivity (animal), captivity, an example being the military macaw. There are currently 5196 animals and 6789 plants classified as Vulnerable, compared with 1998 levels of 2815 and 3222, respectively. Practices such as cryoconservation of animal genetic resources have been enforced in efforts to conserve vulnerable breeds of livestock specifically. Criteria The International Union for Conservation of Nature uses several criteria to enter species in this category. A tax ...

Pheidole
''Pheidole'' is a genus of ants that belongs to the ant subfamily Myrmicinae. The genus is widespread and ecologically dominant. It probably includes more than 1000 species. The genus first evolved in the Americas, eventually spreading across the globe. Colony structure Most species of ''Pheidole'' are dimorphic, which means that colonies contain two castes of workers, the "minor" workers, and the "major" workers, or "soldiers". The latter generally have much larger heads and mandibles in comparison to their usually fairly modest body size. In addition, as in other ant species, a colony may contain one or several queens, and also in mature colonies, alates - virgin winged females and males. Pheidole_xerophila-major_minors.jpg, major and minor workers of ''P. xerophila'' Major workers The distinctive major workers have earned the genus ''Pheidole'' the nickname of "big-headed ants". The major workers of a ''Pheidole'' colony, while they may look fierce, are often quite sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inquiline
In zoology, an inquiline (from Latin ''inquilinus'', "lodger" or "tenant") is an animal that lives commensally in the nest, burrow, or dwelling place of an animal of another species. For example, some organisms such as insects may live in the homes of gophers or the garages of humans and feed on debris, fungi, roots, etc. The most widely distributed types of inquiline are those found in association with the nests of social insects, especially ants and termites – a single colony may support dozens of different inquiline species. The distinctions between parasites, social parasites, and inquilines are subtle, and many species may fulfill the criteria for more than one of these, as inquilines do exhibit many of the same characteristics as parasites. However, parasites are specifically ''not'' inquilines, because by definition they have a deleterious effect on the host species, while inquilines have not been confirmed to do so. In the specific case of termites, the term "'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
