Xenistius Californiensis
''Xenistius'' is a genus of grunts native to the eastern Pacific Ocean. Species The currently recognized species in this genus are: * '' Xenistius californiensis'' (Steindachner, 1876) (Californian salema) * '' Xenistius peruanus'' Hildebrand, 1946 Systematics The genus ''Haemulon'' was determined to be paraphyletic in molecular studies which showed ''Haemulon chrysargyreum'' clustered with ''Xenistius californianus''. The genus '' Brachygenys'' which had been created by Felipe Poey in 1868 was revived to include these species and ensure the monophyly of ''Haemulon''. The genus also includes the other species in ''Xenistius'' and ''Xenocys''. These changes are recognised by ''Catalog of Fishes'', making ''Xenistius'' a synonym of ''Brachygenys'', but not yet by Fishbase FishBase is a global species database of fish species (specifically finfish). It is the largest and most extensively accessed online database on adult finfish on the web. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
David Starr Jordan
David Starr Jordan (January 19, 1851 – September 19, 1931) was the founding president of Stanford University, serving from 1891 to 1913. He was an ichthyologist during his research career. Prior to serving as president of Stanford University, he had served as president of Indiana University from 1884 to 1891. Starr was also a strong supporter of eugenics, and his published views expressed a fear of "race-degeneration" and asserted that cattle and human beings are "governed by the same laws of selection". He was an antimilitarist since he believed that war killed off the best members of the gene pool, and he initially opposed American involvement in World War I. Early life and career Jordan was born in Gainesville, New York, and grew up on a farm in upstate New York. His parents made the unorthodox decision to educate him at a local girls' high school. His middle name, Starr, does not appear in early census records, and was apparently self-selected; he had begun using ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brachygenys
''Brachygenys'' is a genus of marine ray-finned fish, grunts belonging to the family Haemulidae. The species within the genus are found in the eastern Pacific Ocean and western Atlantic Ocean. It is not yet recognised by Fishbase but is by the Catalog of Fishes. Species The following species are classified within the genus ''Brachygenys'': * '' Brachygenys californiensis'' (Steindachner, 1875) (California salema) * '' Brachygenys chrysargyrea'' ( Gũnther, 1860) (Smallmouth grunt) * '' Brachygenys jessiae'' Jordan & Bollman, 1890 (Black-striped salema) * '' Brachygenys peruanus'' (Hildebrand, 1856) Systematics The type species of ''Brachygenys'' is ''Haemulon chrysargyreum'' which as ''H. taeniatum'' was described by the Cuban zoologist Felipe Poey (1799-1891) but that taxon is a junior synonym of ''H. chrysargyreum''. Fishbase still places ''H. chrysargyreum'' in the genus ''Haemulon'', molecular studies now suggest that ''Haemulon'' ''sensu lato'' is paraphyletic because ''H. ...

Haemulinae
Haemulinae is a subfamily of the Haemulidae and consists of the genera of that family which are regarded as being of New World origin, although they are now widespread. The subfamily is distinguished from the Plectorhynchinae by having a short dorsal fin which contains 13-16 soft rays, as opposed to the long dorsal fin with 17-26 soft rays of the subfamily Plectorhynchinae. Genera The following genera are included in the Haemulinae: * ''Anisotremus'' Gill 1861 * '' Boridia'' Cuvier, 1830 * ''Brachydeuterus'' Gill, 1862 * '' Conodon'' Cuvier, 1830 * '' Emmelichthyops'' Schultz, 1945 * ''Haemulon'' Cuvier, 1829 * '' Haemulopsis'' Steindachner, 1869 * ''Isacia'' Jordan & Fesler, 1893 * '' Microlepidotus'' Gill, 1862 * ''Orthopristis'' Girard, 1858 * '' Parakuhlia'' Pellegrin, 1913 * ''Pomadasys'' Lacépède, 1802 * '' Xenichthys'' Gill, 1862 * ''Xenistius'' Jordan & Gilbert, 1883 * '' Xenocys'' Jordan & Bollman, 1890 The genus '' Brachygenys'' is recognised by some auth ...

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Catalog Of Fishes
Catalog of Fishes is a comprehensive on-line database and reference work on the scientific names of fish species and genera. It is global in its scope and is hosted by the California Academy of Sciences. It has been compiled and is continuously updated by the curator emeritus of the CAS fish collection, William N. Eschmeyer. The taxonomy maintained by the Catalog of Fishes is considered authoritative and it is used as a baseline reference for instance by the broader global fish database FishBase, which involves cross-references to the Catalog's information for all accepted taxa. , the searchable catalogue contains entries for about 58,300 fish species names, about 33,400 of which are currently accepted (valid), and for some 10,600 genera (5,100 valid).

Xenocys
''Xenocys jessiae'', the black-striped salema, is a species of marine ray-finned fish, a grunt belonging to the family Haemulidae. It is endemic to the eastern Pacific Ocean. Description ''Xenocys jessiae'' has a relatively slender, elongated body, notably different from most related species. The head is conical in shape and has large eyes and a short diagonal mouth with a protruding lower jaw. It has very small teeth which are set in bands on the flaws and the palate. The dorsal fin is not continuous, the anterior spiny portion is completely divided from the posterior soft- rayed part. The dorsal fin contains 10 spines in the anterior portion and a single spine and 13-14 soft rays. The anal fin has 3 small spines and 10-11 soft rays. This species attains a maximum total length of . The back is dark silvery-grey in colour, frequently showing yellowish green, yellowish blue or blue-green tints. The colour shades to paler silver on the flanks and to silvery-white on the underparts. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monophyly
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have taken ...

Felipe Poey
Felipe Poey (May 26, 1799 – January 28, 1891) was a Cuban zoologist. Biography Poey was born in Havana, the son of French and Spanish parents. He spent several years (1804 to 1807) of his life in Pau then studied law in Madrid. He became a lawyer in Spain but was forced to leave due to his liberal ideas, returning to Cuba in 1823. He began to concentrate on the study of the natural science and traveled to France in 1825 with his wife. He began writing on the butterflies of Cuba and acquiring knowledge on fish, later supplying Georges Cuvier and Valenciennes with fish specimens from Cuba. He took part in the foundation, in 1832, of the Société Entomologique de France. Poey returned to Cuba in 1833 where he founded the Museum of Natural History in 1839. In 1842 he became the first professor of zoology and comparative anatomy at the University of Havana The University of Havana or (UH, ''Universidad de La Habana'') is a university located in the Vedado district of Hava ...

Charles Henry Gilbert
Charles Henry Gilbert (December 5, 1859 in Rockford, Illinois – April 20, 1928 in Palo Alto, California) was a pioneer ichthyologist and Fisheries science, fishery biologist of particular significance to natural history of the western United States. He collected and studied fishes from Central America north to Alaska and described many new species. Later he became an expert on Pacific salmon and was a noted conservation movement, conservationist of the Pacific Northwest. He is considered by many as the intellectual founder of American fisheries biology. He was one of the 22 "pioneer professors" (founding faculty) of Stanford University. Early life and education Born in Rockford, Illinois, Gilbert spent his early years in Indianapolis, Indiana, where he came under the influence of his high school teacher, David Starr Jordan (1851‒1931). When Jordan became Professor of Natural History at Butler University in Indianapolis, Gilbert followed and received his B.A. degree in 187 ...

Paraphyletic
In taxonomy (general), taxonomy, a group is paraphyletic if it consists of the group's most recent common ancestor, last common ancestor and most of its descendants, excluding a few Monophyly, monophyletic subgroups. The group is said to be paraphyletic ''with respect to'' the excluded subgroups. In contrast, a monophyletic group (a clade) includes a common ancestor and ''all'' of its descendants. The terms are commonly used in phylogenetics (a subfield of biology) and in the tree model of historical linguistics. Paraphyletic groups are identified by a combination of Synapomorphy and apomorphy, synapomorphies and symplesiomorphy, symplesiomorphies. If many subgroups are missing from the named group, it is said to be polyparaphyletic. The term was coined by Willi Hennig to apply to well-known taxa like Reptilia (reptiles) which, as commonly named and traditionally defined, is paraphyletic with respect to mammals and birds. Reptilia contains the last common ancestor of reptiles a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
