Trachemys Gaigeae
The Big Bend slider (''Trachemys gaigeae''), also called commonly the Mexican Plateau slider and ''la jicotea de la meseta mexicana'' in Mexican Spanish, is a species of aquatic turtle in the family Emydidae. The species is native to the Southwestern United States and northern Mexico. Taxonomy The species ''Trachemys gaigeae'' was first described by professor of zoology at the University of Michigan, Dr. Norman Edouard Hartweg, in 1939, as a subspecies, ''Pseudemys scripta gaigeae''. Later, it was assigned to the genus ''Chrysemys'', then to the genus ''Trachemys''. Most recently, it was granted full species status, though many sources still refer to it by its various synonyms. The Nazas slider (''T. hartwegi)'' of the Nazas River in northern Mexico was formerly considered a subspecies of ''T. gaigeae'', but was reclassified as a distinct species by the Turtle Taxonomy Working Group and the Reptile Database in 2021. Geographic range ''T. gaigeae'' is native to the United Stat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norman Edouard Hartweg
Norman Edouard "Kibe" Hartweg (August 20, 1904 – February 16, 1964) was an American herpetologist, Curator of Herpetology for the Museum of Zoology at the University of Michigan, and president of the American Society of Ichthyologists and Herpetologists. He was a specialist in the taxonomy and distribution of turtles, and is honored by having a subspecies of turtle named after him: the western spiny softshell turtle, '' Apalone spinifera hartwegi''. He is also credited with having described several new species, including the Big Bend slider, '' Trachemys gaigeae'', the Oaxacan patchnose snake, '' Salvadora intermedia'', and Dunn's hognose pit viper, '' Porthidium dunni''. The scientific exploits of Hartweg also led him to discover a corpse of a murdered lady in 1932, in an area that later became the Pymatuning Reservoir. The case was never solved. Career Hartweg attained his doctorate at the University of Michigan in 1934 under the direction of Dr. Alexander Grant Ruthven a ...

Turtle Taxonomy Working Group
The Turtle Taxonomy Working Group (TTWG) is an informal working group of the IUCN/SSC Tortoise and Freshwater Turtle Specialist Group (TFTSG). It is composed of a number of leading turtle taxonomists, with varying participation by individual participants over the years, some dropping out and others joining. Works The TTWG has produced an annual checklist of living and recently extinct turtles since 2007, deliberates on proposed changes to turtle taxonomy, and describes its consideration whether to accept, reject, or suspend adoption of proposed changes in a series of annotations to the checklist. Recent versions of the checklist have included full primary synonymies and citations to all original descriptions of recent turtle taxa, as well as CITES CITES (shorter acronym for the Convention on International Trade in Endangered Species of Wild Fauna and Flora, also known as the Washington Convention) is a multilateral treaty to protect endangered plants and animals from the thre ...

Nazas River
The Nazas River is a river located in northern Mexico, in the states of Coahuila and Durango. It is part of the endorheic Bolsón de Mapimí. It is only long, but irrigates an area of in the middle of the desert. The Nazas is also nurtured by the San Juan, Ramos, Potreritos, del Oro, Nazas, Santiago, Tepehuanes and Peñón Blanco rivers. The river starts at the Sierra Madre Occidental. The aboriginal title for this stream is ''Tlahualilo'', coming from the Nahuatl words ''tlalli'' meaning "fertile land" and ''ahualila'', meaning "water for irrigation". Etymology The Nazas took its name when the Spaniards, during the conquest of Mexico in the early 1500s, saw the original inhabitants on the shore of the river fishing with fish traps, whose Spanish name is 'nasa', for that reason it became known as the 'river of nazas'. Ecology The Nazas watershed contains considerable desertic habitat, outside of the immediate riparian zone. A large variety of flora and fauna populate the ...

Nazas Slider
The Nazas slider (''Trachemys hartwegi'') is a species of turtle in the family Emydidae. It is endemic to northern Mexico. Taxonomy It was formerly considered a subspecies of the Big Bend slider (''T. gaigeae''), but in 2021 it was reclassified as a distinct species by the Turtle Taxonomy Working Group and the Reptile Database. Both ''hartwegi'' and ''gaigeae'' may have originally evolved in endorheic basins until their respective basins were captured by the Pecos- Grande system. Distribution It is endemic to Mexico, where it is only found in the main channel of the Nazas River in northeastern Durango and southwestern Coahuila. Status Although presently considered conspecific with ''T. gaigeae'' on the IUCN Red List, with ''T. gaigeae'' as a whole classified as Vulnerable, ''T. hartwegi'' qualifies for Endangered An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdicti ...

Zoology
Zoology ( , ) is the scientific study of animals. Its studies include the anatomy, structure, embryology, Biological classification, classification, Ethology, habits, and distribution of all animals, both living and extinction, extinct, and how they interact with their ecosystems. Zoology is one of the primary branches of biology. The term is derived from Ancient Greek , ('animal'), and , ('knowledge', 'study'). Although humans have always been interested in the natural history of the animals they saw around them, and used this knowledge to domesticate certain species, the formal study of zoology can be said to have originated with Aristotle. He viewed animals as living organisms, studied their structure and development, and considered their adaptations to their surroundings and the function of their parts. Modern zoology has its origins during the Renaissance and early modern period, with Carl Linnaeus, Antonie van Leeuwenhoek, Robert Hooke, Charles Darwin, Gregor Mendel a ...

Emydidae
Emydidae (Latin (freshwater tortoise) + Ancient Greek (, "appearance, resemblance")) is a family of testudines (turtles) that includes close to 50 species in 10 genera. Members of this family are commonly called terrapins, pond turtles, or marsh turtles. Several species of Asian box turtles were formerly classified in the family; however, revised taxonomy has separated them to a different family ( Geoemydidae). As currently defined, the Emydidae are entirely a Western Hemisphere family, with the exception of two species of pond turtle. Description The upper shell (carapace) of most emydids is the shape of a low arch, although in some species, it is domed. The upper shell may have one or two ridges that run from front to the back of the animal (a projection commonly called a "keel"), or such a feature may be absent. A prominent bridge often connects the top shell to the bottom shell (plastron). Emydids have large bottom shells, and some members of the family have a movable ...

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 ...
