Stanley Howard Weitzman
Stanley Howard Weitzman (born March 16, 1927, in Mill Valley, California; died February 16, 2017) was a Research Scientist Emeritus at Division of Fishes, National Museum of Natural History, Washington, D.C. Life and career He received his Bachelor's (1951) and Master's (1953) degrees in biology from the University of California, Berkeley, and his PhD (1960) from Stanford University as a student of the venerable killifish expert, George Sprague Myers. Weitzman began his long and distinguished career as a Curator in the Division of Fishes, National Museum of Natural History, in 1962. At that time he moved from California with his wife Marilyn and their two children. Awards and recognition Weitzman's outstanding research was recognized by his peers: he received the Robert H. Gibbs, Jr. Memorial Award for Excellence in Systematic Ichthyology for an outstanding body of published work in systematic ichthyology from the American Society of Ichthyologists and Herpetologists in 1991, and ...

Taxa Named By Stanley Howard Weitzman
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 still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Characini
Characidae, the characids, is a family of freshwater subtropical and tropical fish belonging to the order Characiformes. They are found throughout much of Central and South America, including such major waterways as the Amazon and Orinoco Rivers.Nelson (2006) These fish vary in length; many are less than . The name " characins" is a historical one, but scientists today tend to prefer "characids" to reflect their status as a, by and large, monophyletic group (at family rank). This family includes some of the first characiforms to be described to science, such as '' Charax'' and '' Tetragonopterus'', and thus lend their name to the order, as well as to common names such as "characin" and " tetra". Past taxonomic treatments had a much more expansive definition of the family, including numerous South American fish families such as the piranhas and dorados, as well as the African alestids. Following multiple taxonomic revisions, this was eventually restricted to just the American ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
