Pristionchus Occultus
''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 "stenostomatous" mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Erotylidae
''Ischyrus quadripunctatus'' Erotylidae, or the pleasing fungus beetles, is a family of beetles belonging to Cucujoidea containing over 100 genera. In the present circumscription, it contains 6 tribes ( Tritomini, Dacnini, Megalodacnini, Erotylini, Cryptophilini, and Languriini) and 10 subfamilies ( Cryptophilinae, Dacninae, Encaustinae, Erotylinae, Languriinae, Loberinae, Megalodacninae, Pharaxonothinae, Tritominae, and Xenoscelinae). In other words, the narrowly circumscribed Erotylidae correspond to the subfamily Erotylinae in the definition '' sensu lato''. There are doubts on the monophyly of lower ranked taxa within Erotylidae, with further phylogenetic studies requiring better sampling and studies of unexplored character sets, for example the metendosternite and penile flagellum, which are generally lacking detailed morphological studies within the Coleoptera literature. The Eroytlina taxonomy is based on traits such as their different colors and not off mor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Staphylinidae
The rove beetles are a family (biology), family (Staphylinidae) of beetles, primarily distinguished by their short elytra (wing covers) that typically leave more than half of their abdominal segments exposed. With over 66,000 species in thousands of genera, the group is one of the largest families in the beetle order, and one of the largest families of organisms. It is an ancient group that first appeared during the Middle Jurassic based on definitive records of fossilized rove beetles, with the Late Triassic taxon ''Leehermania'' more likely belonging to Myxophaga. 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 (''Ocypus olens''). For some other species, see List of rove beetle (Staphylinidae) species recorded in Britain, list of British rove beetles.

Part of the Mascarene Islands, it is located approximately east of the island of Madagascar and southwest of the island of Mauritius. , it had a population of 896,175. Its capital and largest city is Saint-Denis, La Réunion, Saint-Denis. Réunion was uninhabited until French immigrants and colonial subjects settled the island in the 17th century. Its tropical climate led to the development of a plantation economy focused primarily on sugar; slaves from East Africa were imported as fieldworkers, followed by Malays, Annamite, Vietnamese, Chinese, and Indians as indentured laborers. Today, the greatest proportion of the population is of mixed descent, while the predominant language is Réunion Creole, though French remains the sole official language. Since 1946, Réunion has been governed as a regions of France, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ficus Auriculata
''Ficus auriculata'' (the Roxburgh fig, ''Elephant ear tree'') is a type of fig tree, native to subtropical and tropical mainland Asia. It is noted for its big and round leaves and edible fruit. Description This plant is a small tree of high with numerous bristle-covered branches. The leaves are big and round, and are up to long and wide, with cordate or rounded base, acute apex, and 5–7 main veins from the leaf base. Its petioles are up to long, and it has stipules of about long. The plant has oblate syconium that are up to wide, covered with yellow pubescence, and emerge from the trunk or old branches of the tree. ''Ficus auriculata'' is dioecious, with male and female flowers produced on separate individuals. On ripening, the fruits turn from light yellow to purple. The fruit is a fleshy receptacle. The fruits form as large clusters on the trunk, on branches and also on the roots. Fruit extracts contain many phenolic compounds (Gaire et al. 2011). Taxonomy It was firs ...
