Podocopida Genera
The Podocopida are an order of ostracods in the subclass Podocopa. It is the most diverse of the five orders of ostracods, and the only one with freshwater species. The group also has a rich fossil record. The superfamily Cytheroidea in the suborder Cytherocopina consists of non-swimming crawlers and burrowers. Most species are marine, but at least seven extant lineages have independently adapted to freshwater. The largest freshwater family is Limnocytheridae, with about 150 species in 20 genera. Taxonomy The following suborders and unassigned taxa are contained in the order Podocopida: * Superfamily Carbonitacea * Suborder Bairdiocopina * Suborder Cypridocopina * Suborder Cytherocopina * Suborder Darwinulocopina * Suborder Sigilliocopina See also * Cyprididae Cyprididae is "the most diverse group of freshwater ostracods". It contains over 1000 species, which represents 50% of the known species of freshwater ostracods (other speciose families include Candonidae, ...

Georg Ossian Sars
Prof Georg Ossian Sars HFRSE (20 April 1837 – 9 April 1927) was a Norway, Norwegian marine biology, marine and freshwater biology, freshwater biologist. Life Georg Ossian Sars was born on 20 April 1837 in Kinn (former municipality), Kinn, Norway (now part of Flora, Norway, Flora), the son of Pastor Michael Sars and Maren Sars; the historian Ernst Sars was his elder brother, and the singer and women's skiing pioneer Eva Nansen was his younger sister.Google Translate He grew up in Manger, Norway, Manger, Hordaland, where his father was the local priest. He studied from 1852 to 1854 at Bergen Cathedral School, from 1854 at Oslo Cathedral School, Christiania Cathedral School, and joined the university at Christiana (now the University of Oslo) in 1857. He indulged his interest in natural history while studying medicine; having collected water fleas in local lakes with Wilhelm Lilljeborg's works, he discovered new species, and this resulted in his first scientific publication.

Order (biology)
Order () is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between family and class. In biological classification, the order is a taxonomic rank used in the classification of organisms and recognized by the nomenclature codes. An immediately higher rank, superorder, is sometimes added directly above order, with suborder directly beneath order. An order can also be defined as a group of related families. What does and does not belong to each order is determined by a taxonomist, as is whether a particular order should be recognized at all. Often there is no exact agreement, with different taxonomists each taking a different position. There are no hard rules that a taxonomist needs to follow in describing or recognizing an order. Some taxa are accepted almost universally, while others are recognized only rarely. The name of an order is usually written with a capital letter. For some groups of organisms, their orders may follow consist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ostracod
Ostracods, or ostracodes, are a Class (biology), class of the crustacean, Crustacea (class Ostracoda), sometimes known as seed shrimp. Some 33,000 species (only 13,000 of which are extant taxon, extant) have been identified,Brandão, S.N.; Antonietto, L.S; Nery, D.G.; Santos, S.G.; Karanovic, I. (2023). World Ostracoda Database.

They are small crustaceans, typically around in size, but varying from , the latter in the case of the marine ''Gigantocypris.'' The largest known freshwater species is ''Megalocypris princeps'', which reach 8 mm in length. In most cases, their bodies are flattened from side to side and protected by a bivalve-like valve or "shell" made of chitin, and often calcium carbonate. The family Entocytheridae and many planktonic forms do not have calcium carbonate. The hinge of the two valves is in the upper (dorsal) region of the body. Ostracods are grouped toget ...

Podocopa
The Podocopa are a subclass of ostracods. Members of the subclass Podocopa can be differentiated from the other subclass of ostracods ( Myodocopa) by the morphology of the second antenna: the Podocopa have a relatively long endopod, whereas the Myodocopa have a relatively long exopod. The seventh limb of the Podocopa has a variety of forms or is absent, but is never an annulated worm-like limb (as seen in some Myodocopa). Taxonomy The following orders and unplaced families are recognised in the subclass Podocopa: * Order Palaeocopida * Order PlatycopidaBrandão, S.N.; Antonietto, L.S; Nery, D.G.; Santos, S.G.; Karanovic, I.

Fossil Record
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Though the fossil record is incomplete, numerous studies have demonstrated that there is enough information available to give a good understanding of the pattern of diversification of life on Earth. In addition, the record can predict and fill gaps such as the discovery of '' Tiktaalik'' in the arctic of Canada. Paleontology includes the study of fossils: their age, method of formation, and evolutionary significance. Specimens are sometimes considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years to 4.1 billion years old. Early edition, published online before print. Th ...

Hydrobiologia
''Hydrobiologia'', ''The International Journal of Aquatic Sciences'', is a peer-reviewed scientific journal publishing 21 issues per year, for a total of well over 4000 pages per year. ''Hydrobiologia'' publishes original research, reviews and opinions investigating the biology of freshwater and marine habitats, including the impact of human activities. Coverage includes molecular-, organism-, community -and ecosystem-level studies dealing with biological research in limnology and oceanography, including systematics and aquatic ecology. In addition to hypothesis-driven experimental research, it presents theoretical papers relevant to a broad hydrobiological audience, and collections of papers in special issues covering focused topics. History ''Hydrobiologia'' changed on the appointment of Henri Dumont to be its editor-in-chief. He introduced peer review, and expanded production from 6 issues per year to more than 20 per year. Koen Martens took over the responsibility as editor-i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
