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 served as president of Indiana University Bloomington, Indiana University from 1885 to 1891. Jordan was also a strong supporter of eugenics, and his published views expressed a fear of "race-degeneration", asserting 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 education Jordan was born in Gainesville (town), New York, Gainesville, New York, and grew up on a farm in upstate New York. His parents made an unorthodox decision to educate him at a local girls' high school. His middle name, Starr, does not appear in early census records, ...

Johann Jakob Von Tschudi
Johann Jakob von Tschudi (25 July 1818 – 8 October 1889) was a Switzerland, Swiss naturalist, explorer, and diplomat. He is known for his travels in South America, his scientific contributions to zoology and anthropology, and his diplomatic service for Switzerland. Early life and education Tschudi was born in Glarus to Johann Jakob Tschudi, a merchant, and Anna Maria Zwicky. He studied natural sciences and medicine at the universities of Neuchâtel, Leiden, and Paris. Exploration and scientific work In 1838, Tschudi travelled to Peru, where he remained for five years exploring and collecting plants in the Andes. He moved to Vienna in 1843. In 1845, he described 18 new species of South American reptiles. Between 1857 and 1859, he visited Brazil and other countries in South America. Tschudi wrote a textbook on Peru titled ''Peruvian Antiquities'' in which he recorded various aspects of Peruvian life and history. In the book, he explained the various skull angles of Peruvians in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Ray-finned Fish
Actinopterygii (; ), members of which are known as ray-finned fish or actinopterygians, is a class of bony fish that comprise over 50% of living vertebrate species. They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines called '' lepidotrichia'', as opposed to the bulkier, fleshy lobed fins of the sister clade Sarcopterygii (lobe-finned fish). Resembling folding fans, the actinopterygian fins can easily change shape and wetted area, providing superior thrust-to-weight ratios per movement compared to sarcopterygian and chondrichthyian fins. The fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the articulation between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). The vast majority of actinopterygians are teleosts. By species count, they dominate the subphylum Vertebrata, and constitute nearly 99% of the over 30,000 extant ...

Family (biology)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community ...

Sciaenidae
Sciaenidae is a family (biology), family of ray-finned fishes belonging to the Order (biology), order Acanthuriformes. They are commonly called drums or croakers in reference to the repetitive throbbing or drumming sounds they make. The family consists of about 293 to 298 species in about 66 or 67 genera. Taxonomy Sciaenidae was first proposed as a family in 1829 by the French zoologist Georges Cuvier. The 5th edition of ''Fishes of the World'' classifies the family in the suborder Sciaenoidei, alongside the rover family Emmelichthyidae, in the order Acanthuriformes. Other authorities classify the Sciaenidae and the Emmelichthyidae as ''incertae sedis'' within the series Eupercaria. The ''Catalog of Fishes'' retains this family within the Acanthuriformes but does not recognise the suborder Sciaenoidei. The 5th edition of ''Fishes of the World'', ''FishBase, Fishbase'' and ''Catalog of Fishes'' do not recognise Subfamily, subfamilies within the Sciaenidae but many workers on these ...

Taxa Named By David Starr Jordan
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] |
