Ceratoperidinium Margalefii
''Ceratoperidinium margalefii'', also known as ''Ceratoperidinium yeye,'' is a species of dinoflagellates. This species has two flagella A flagellum (; ) is a hairlike appendage that protrudes from certain plant and animal sperm cells, and from a wide range of microorganisms to provide motility. Many protists with flagella are termed as flagellates. A microorganism may have f .... Their resemblance to the legs of a girl dancing inspired its original name, ''Ceratoperidinium yeye'', in reference to the female-dominated yé-yé pop music and dance of the 1960s.

SAR Supergroup
The SAR supergroup, also just SAR or Harosa, is a clade that includes stramenopiles (heterokonts), alveolates, and Rhizaria. The name is an acronym derived from the first letters of each of these clades; it has been alternatively spelled "RAS". The term "Harosa" (at the subkingdom level) has also been used. The SAR supergroup is a node-based taxon. Note that as a formal taxon, "Sar" has only its first letter capitalized, while the earlier abbreviation, SAR, retains all uppercase letters. Both names refer to the same group of organisms, unless further taxonomic revisions deem otherwise. Members of the SAR supergroup were once included under the separate supergroups Chromalveolata (Chromista and Alveolata) and Rhizaria, until phylogenetic studies confirmed that stramenopiles and alveolates diverged with Rhizaria. This apparently excluded haptophytes and cryptomonads, leading Okamoto ''et al.'' (2009) to propose the clade Hacrobia to accommodate them. Phylogeny Based on a compi ...

Gymnodiniales
The Gymnodiniales are an order of dinoflagellates, of the class Dinophyceae. Members of the order are known as gymnodinioid or gymnodinoid (terms that can also refer to any organism of similar morphology). They are athecate, or lacking an armored exterior, and as a result are relatively difficult to study because specimens are easily damaged. Many species are part of the marine plankton and are of interest primarily due to being found in algal blooms. As a group the gymnodinioids have been described as "likely one of the least known groups of the open ocean phytoplankton." Of the families in the order, the Polykrikaceae and Warnowiaceae are well known for possessing exceptionally complex assemblies of organelles, such as nematocysts, trichocysts, and pistons. The Warnowiaceae uniquely possess an ocelloid, an extremely complex light-sensitive subcellular structure composed of mitochondria and plastid The plastid (Greek: πλαστός; plastós: formed, molded – plural plastids ...

Ceratoperidiniaeceae
''Ceratoperidiniaeceae'' is a family of unarmored dinoflagellates in the order Gymnodiniales The Gymnodiniales are an order of dinoflagellates, of the class Dinophyceae. Members of the order are known as gymnodinioid or gymnodinoid (terms that can also refer to any organism of similar morphology). They are athecate, or lacking an armore ..., first described in 2013. The family is named for the first described species, '' Ceratoperidinium margalefii''. Members of the family were found to have morphological similarities, particularly the acrobase structure which was found to be common among the species included in the family. Member species possess chloroplasts. References {{Taxonbar, from=Q42266377 Taxa described in 2013 Gymnodiniales Dinoflagellate families ...

Ceratoperidinium
''Ceratoperidinium'' is a genus of dinoflagellates in the order Gymnodiniales. The genus contains two species. It was first created in 1969 by Margalef, with ''Ceratoperidinium yeye'' as the type species In zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological type specimen .... However, because it was not correctly described it was considered invalid, as was ''C. yeye''. In 1980, Lobelich III described the genus as ''Ceratoperidinium'' Margalef ''ex'' Loeblich III, renaming ''C. yeye'' as ''C. margalefii''. In 2014, ''Gyrodinium falcatum'' was reassigned to ''Ceratoperidinium'' based on genetic analysis. References {{Taxonbar, from=Q20676923 Dinoflagellate genera Gymnodiniales ...

Dinoflagellate
The dinoflagellates (Greek δῖνος ''dinos'' "whirling" and Latin ''flagellum'' "whip, scourge") are a monophyletic group of single-celled eukaryotes constituting the phylum Dinoflagellata and are usually considered algae. Dinoflagellates are mostly marine plankton, but they also are common in freshwater habitats. Their populations vary with sea surface temperature, salinity, and depth. Many dinoflagellates are photosynthetic, but a large fraction of these are in fact mixotrophic, combining photosynthesis with ingestion of prey (phagotrophy and myzocytosis). In terms of number of species, dinoflagellates are one of the largest groups of marine eukaryotes, although substantially smaller than diatoms. Some species are endosymbionts of marine animals and play an important part in the biology of coral reefs. Other dinoflagellates are unpigmented predators on other protozoa, and a few forms are parasitic (for example, ''Oodinium'' and ''Pfiesteria''). Some dinoflagellates pro ...

Flagella
A flagellum (; ) is a hairlike appendage that protrudes from certain plant and animal sperm cells, and from a wide range of microorganisms to provide motility. Many protists with flagella are termed as flagellates. A microorganism may have from one to many flagella. A gram-negative bacterium ''Helicobacter pylori'' for example uses its multiple flagella to propel itself through the mucus lining to reach the stomach epithelium, where it may cause a gastric ulcer to develop. In some bacteria the flagellum can also function as a sensory organelle, being sensitive to wetness outside the cell. Across the three domains of Bacteria, Archaea, and Eukaryota the flagellum has a different structure, protein composition, and mechanism of propulsion but shares the same function of providing motility. The Latin word means " whip" to describe its lash-like swimming motion. The flagellum in archaea is called the archaellum to note its difference from the bacterial flagellum. Eukaryoti ...

Yé-yé
''Yé-yé'' () (''yeyé'' in Spanish) was a style of pop music that emerged in Western-Southern Europe in the early 1960s. The French term "''yé-yé''" was derived from the English "yeah! yeah!", popularized by British beat music bands such as the Beatles. The style expanded worldwide as the result of the success of figures such as French singer-songwriters Sylvie Vartan, Serge Gainsbourg and Françoise Hardy. Yé-yé was a particular form of counterculture that derived most of its inspiration from British and American rock and roll. Additional stylistic elements of ''yé-yé'' song composition include baroque, exotica, pop, jazz and the French ''chanson.'' History The movement had its origins in the radio program (loosely translated as "hello mates" or "hello pals"), created by Jean Frydman and hosted by Daniel Filipacchi and Frank Ténot, which first aired in December 1959. The phrase "''Salut les copains''" dates back to the title of a 1957 song by Gilbert Bécaud and Pier ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Described In 1969
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
