Pristionchus Boliviae
''Pristionchus'' is a genus of nematodes (roundworms) in the family Diplogastridae that currently includes more than 50 described species. They are known mainly as non-parasitic associates of insects, especially beetles, while others have been reported from soil, organic matter, or rotting wood. The genus includes '' P. pacificus'', a satellite model organism to the well-studied nematode ''Caenorhabditis elegans''. Ecology and mouth dimorphism In ''Pristionchus'' species associated with insects, the nematodes usually live on their hosts in a dormant stage (the dauer larva). After the death of the host insect, the nematodes resume development, feeding and reproducing on the decaying host carcass. Most species of ''Pristionchus'' show a polyphenism in their feeding structures, which allows the nematodes to access different food resources in this rapidly changing environment. In one form (the "stenostomatous" form), the mouth is elongated, narrow, and equipped with one small tooth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pristionchus Pacificus
''Pristionchus pacificus'' is a species of free-living nematodes (roundworms) in the family Diplogastridae. The species has been established as a satellite model organism to '' Caenorhabditis elegans'', with which it shared a common ancestor 200–300 million years ago. The genome of ''P. pacificus'' has been fully sequenced, which in combination with other tools for genetic analysis make this species a tractable model in the laboratory, especially for studies of developmental biology. Mouth dimorphism Like other species of '' Pristionchus'' and many other free-living nematodes, ''P. pacificus'' exhibits a polyphenism in its mouthparts that allows individual nematodes to specialize on different food sources, which has made the species a case study in phenotypic plasticity. The polyphenism has two forms (morphs). The most common type, at least in wild-type lab strains, is the "eurystomatous" morph, which can feed on both bacteria and other nematode species. The "stenostomat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Staphylinidae
The rove beetles are a family (Staphylinidae) of beetles, primarily distinguished by their short elytra (wing covers) that typically leave more than half of their abdominal segments exposed. With roughly 63,000 species in thousands of genera, the group is currently recognized as the largest extant family of organisms. It is an ancient group, with fossilized rove beetles known from the Triassic, 200 million years ago, and possibly even earlier if the genus ''Leehermania'' proves to be a member of this family. They are an ecologically and morphologically diverse group of beetles, and commonly encountered in terrestrial ecosystems. One well-known species is the devil's coach-horse beetle. For some other species, see list of British rove beetles. Anatomy As might be expected for such a large family, considerable variation exists among the species. Sizes range from <1 to , with most in the 2–8 mm range, and the form is generally elongated, with some rove beetles being ovoid i ...

Réunion
Réunion (; french: La Réunion, ; previously ''Île Bourbon''; rcf, label= Reunionese Creole, La Rényon) is an island in the Indian Ocean that is an overseas department and region of France. It is located approximately east of the island of Madagascar and southwest of the island of Mauritius. , it had a population of 868,846. Like the other four overseas departments, Réunion also holds the status of a region of France, and is an integral part of the French Republic. Réunion is an outermost region of the European Union and is part of the eurozone. Réunion and the fellow French overseas department of Mayotte are the only eurozone regions located in the Southern Hemisphere. As in the rest of France, the official language of Réunion is French. In addition, a majority of the region's population speaks Réunion Creole. Toponymy When France took possession of the island in the seventeenth century, it was named Bourbon, after the dynasty that then ruled France. To break ...

Species Complex
In biology, a species complex is a group of closely related organisms that are so similar in appearance and other features that the boundaries between them are often unclear. The taxa in the complex may be able to hybridize readily with each other, further blurring any distinctions. Terms that are sometimes used synonymously but have more precise meanings are cryptic species for two or more species hidden under one species name, sibling species for two (or more) species that are each other's closest relative, and species flock for a group of closely related species that live in the same habitat. As informal taxonomic ranks, species group, species aggregate, macrospecies, and superspecies are also in use. Two or more taxa that were once considered conspecific (of the same species) may later be subdivided into infraspecific taxa (taxa within a species, such as bacterial strains or plant varieties), that is complex but it is not a species complex. A species complex is in most cas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
