Bicosoecida
Bicosoecida ( ICZN) or Bicosoecales/Bicoecea (ICBN) is an order of Bikosea, a small group of unicellular flagellates, included among the heterokonts. Informally known as bicosoecids, they are a small group of unicellular flagellates. The cells are free-living, with no chloroplasts, and in some genera are encased in a lorica. The name of the type genus ''Bicosoeca'' described by James-Clark in 1866 is derived from Greek roots (, vase, bowl, plus ''oekein'', inhabit). The philologically preferable compound would be ''Bicoeca'', as "corrected" by Stein in 1878 and followed by most subsequent authors. However, according to the ICBN and ICZN, the original spelling of the name cannot be considered incorrect and it must be used in its original form. The group was formerly considered to be related to the Chrysophyceae. Some authors use the vernacular term "bicosoecid" (or "bicoecid") in a narrower sense, only for ''Bicosoeca'', applying "bicoeceans" to ''Bicosoeca'' and related g ...

Cafeteria Roenbergensis
''Cafeteria roenbergensis'' is a small bacterivorous marine flagellate. It was discovered by Danish marine ecologist Tom Fenchel and named by him and taxonomist David J. Patterson in 1988. It is in one of three genera of bicosoecids, and the first discovered of two known ''Cafeteria'' species. Bicosoecids belong to a broad group, the stramenopiles, also known as heterokonts (Heterokonta) that includes photosynthetic groups such as diatoms, brown, and golden algae, and non-photosynthetic groups such as opalinids, actinophryid "heliozoans", and oomycetes. The species is found primarily in coastal waters where there are high concentrations of bacteria on which it grazes. Its voracious appetite plays a significant role in regulating bacteria populations. Physiology ''Cafeteria roenbergensis'' is a slightly flattened, kidney-shaped bicosoecid. Its cell typically measures between 3 and 10 μm and it has a volume of around 20 μm³. It is colorless and has two unequally sized ...

Flagellate
A flagellate is a cell or organism with one or more whip-like appendages called flagella. The word ''flagellate'' also describes a particular construction (or level of organization) characteristic of many prokaryotes and eukaryotes and their means of motion. The term presently does not imply any specific relationship or classification of the organisms that possess flagella. However, the term "flagellate" is included in other terms (such as "dinoflagellate" and "choanoflagellata") which are more formally characterized. Form and behavior Flagella in eukaryotes are supported by microtubules in a characteristic arrangement, with nine fused pairs surrounding two central singlets. These arise from a basal body. In some flagellates, flagella direct food into a cytostome or mouth, where food is ingested. Flagella often support hairs, called mastigonemes, or contain rods. Their ultrastructure plays an important role in classifying eukaryotes. Among protoctists and microscopic anima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heterokont
Heterokonts are a group of protists (formally referred to as Heterokonta, Heterokontae or Heterokontophyta). The group is a major line of eukaryotes. Most are algae, ranging from the giant multicellular kelp to the unicellular diatoms, which are a primary component of plankton. Other notable members of the Stramenopiles include the (generally) parasitic oomycetes, including ''Phytophthora'', which caused the Great Famine of Ireland, and ''Pythium'', which causes seed rot and damping off. The name "heterokont" refers to the type of motile life cycle stage, in which the flagellated cells possess two differently arranged flagella (see zoospore). History In 1899, Alexander Luther created the term "Heterokontae" for some algae with unequal flagella, today called Xanthophyceae. Later, some authors (e.g., Copeland, 1956) included other groups in Heterokonta, expanding the name's sense. The term continues to be applied in different ways, leading to Heterokontophyta being applie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cafeteria (bicosoecid)
''Cafeteria'' is a genus of marine bicosoecid described in 1988 by Tom Fenchel and D. J. Patterson. It was created after the discovery of a new species, ''Cafeteria roenbergensis'', a tiny (5–10 μm) eukaryotic organism that is eaten by protozoa and small invertebrates. The name is meant to indicate the importance of the genus in the food web. At least three species are recognised: * ?''

Samuel Friedrich Stein
Samuel Friedrich Nathaniel Ritter von Stein (November 3, 1818 – January 9, 1885) was a German entomologist. He was Professor at the Royal Saxon Academy of Forestry in Tharandt from 1850–55; and Professor, and later Rector, at the Charles University in Prague, from 1855–76. His scientific work focused on invertebrates, and mainly on ''Diptera''. Early life, education, and family Stein was born in Niemegk, near Potsdam, Brandenburg. He completed his studies in 1841, conducting doctoral work at the University of Berlin. On May 29, 1844, in Berlin, he married Emma Johanne Couard Ottilie (born December 30, 1823, in Berlin; died 2 September 1903, in Asch). The couple had nine children. The next to last, daughter Adelheid von Stein (born May 25, 1859), married Joseph Neuwirth. Career Stein's scientific work focused on invertebrates, and mainly on ''Diptera'', as well as single-celled animals. His work on ''infusoria'' became the basis for all subsequent research in this area. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

International Commission On Zoological Nomenclature
The International Commission on Zoological Nomenclature (ICZN) is an organization dedicated to "achieving stability and sense in the scientific naming of animals". Founded in 1895, it currently comprises 26 commissioners from 20 countries. Organization The ICZN is governed by the "Constitution of the ICZN", which is usually published together with the ICZN Code. Members are elected by the Section of Zoological Nomenclature, established by the International Union of Biological Sciences (IUBS). The regular term of service of a member of the Commission is six years. Members can be re-elected up to a total of three full six-year terms in a row. After 18 continuous years of elected service, a break of at least three years is prescribed before the member can stand again for election. Activities Since 2014, the work of the Commission is supported by a small secretariat based at the National University of Singapore, in Singapore. Previously, the secretariat was based in London and fu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
