Caridina Plicata
''Caridina'' is a genus of freshwater atyid shrimp. They are widely found in tropical or subtropical water in Asia, Oceania and Africa. They are filter-feeders and omnivorous scavengers. They range from 0.9 to 9.8 mm ('' C. cantonensis'') to 1.2–7.4 mm ('' C. serrata'') in carapace length. Taxonomy and species There is evidence for hybridization between sympatric taxa, requiring care when interpreting molecular phylogenetic analyses that do not use a large number of specimens. As of March 2022, the Integrated Taxonomic Information System lists the genus ''Caridina'' as having 340 species. These include the following species: *''Caridina ablepsia'' Guo, Jiang & Zhang, 1992 *''Caridina acuta'' Liang, Chen & W.-X.

Caridina Multidentata
''Caridina multidentata'' is a species of shrimp in the family Atyidae. It is native to Japan and Taiwan.De Grave, S., Shy, J. & Cai, X. 2013''Caridina multidentata''. The IUCN Red List of Threatened Species 2013. Downloaded on 14 June 2016. Its common names include Yamato shrimp, Japanese shrimp, Amano shrimp, and algae shrimp. Description ''Caridina multidentata'' are freshwater shrimp in the family Atyidae and are commonly found in southwestern Japan. They typically grow to 25-35 millimetres. This species of shrimp is amphidromous. Oviposition and hatching occurs in freshwater, and newly hatched larvae drift to saltwater and develop as juveniles, returning to freshwater in their adult forms. The eggs of ''Caridina multidentata'' are rich in yolk and are oval-shaped. The species has adapted to live in fast-flowing water, having a wide and short Rostrum (anatomy), rostrum. ''Caridina multidentata'' begin to take in food in the third Crustacean larva, zoeal stage, relying on in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Integrated Taxonomic Information System
The Integrated Taxonomic Information System (ITIS) is an American partnership of federal agencies designed to provide consistent and reliable information on the taxonomy of biological species. ITIS was originally formed in 1996 as an interagency group within the US federal government, involving several US federal agencies, and has now become an international body, with Canadian and Mexican government agencies participating. The database draws from a large community of taxonomic experts. Primary content staff are housed at the Smithsonian National Museum of Natural History and IT services are provided by a US Geological Survey facility in Denver. The primary focus of ITIS is North American species, but many biological groups exist worldwide and ITIS collaborates with other agencies to increase its global coverage. Reference database ITIS provides an automated reference database of scientific and common names for species. it contains over 839,000 scientific names, synonyms, and ...

Molecular Phylogenetic
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Taxon
In biology, a taxon (back-formation from ''taxonomy''; : taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sympatric
In biology, two closely related species or populations are considered sympatric when they exist in the same geographic area and thus frequently encounter each other. An initially interbreeding population that splits into two or more distinct species sharing a common range exemplifies sympatric speciation. Such speciation may be a product of reproductive isolation – which prevents hybrid offspring from being viable or able to reproduce, thereby reducing gene flow – that results in genetic divergence. Sympatric speciation may, but need not, arise through secondary contact, which refers to speciation or divergence in allopatry followed by range expansions leading to an area of sympatry. Sympatric species or taxa in secondary contact may or may not hybrid (biology), interbreed. Types of populations Four main types of population pairs exist in nature. Sympatric populations (or species) contrast with parapatric populations, which contact one another in adjacent but not sh ...
