Northern Spiny Softshell Turtle
The northern spiny softshell turtle (''Apalone spinifera spinifera'') is a subspecies of soft-shelled turtle in the family Trionychidae. The subspecies is native to the United States and can be found from Montana at the western edge of its range to Vermont and Quebec on the eastern edge. Introduced populations have also been found in Massachusetts, New Jersey, Arizona, and Virginia. Etymology ''Apalone spinifera spinifera'' has sometimes been used only to designate populations east of the Mississippi Populations, while populations west of the Mississippi have been designated ''Apalone spinifera hartwegi''. The subspecific name ''hartwegi'' is in honor of Dr. Norman Edouard Hartweg (1904-1964), who was a specialist in turtles and professor of zoology at the University of Michigan. While some morphological differences exist between northeastern and northwestern populations, a phylogeographic study found little genetic support for a distinction between eastern and western populatio ...

Charles Alexandre Lesueur
Charles Alexandre Lesueur (1 January 1778 in Le Havre – 12 December 1846 in Le Havre) was a French naturalist, artist, and explorer. He was a prolific natural-history collector, gathering many type specimens in Australia, Southeast Asia, and North America, and was also responsible for describing numerous species, including the spiny softshell turtle ('' Apalone spinifera''), smooth softshell turtle ('' A. mutica''), and common map turtle ('' Graptemys geographica''). Both Mount Lesueur and Lesueur National Park in Western Australia are named in his honor. Early life Charles Alexandre Lesueur was born on January 1, 1778, to Jean-Baptiste Denis Lesueur and Charlotte Thieullent. Charlotte died when Charles was sixteen years old, and Charles' maternal grandmother took care of him and his siblings. Charles attended the Collège du Havre and possibly the Ecole publique des mathématiques et d'hydrographie. He was in military service in a cadet battalion at age fifteen and w ...

Fauna Of The Plains-Midwest (United States)
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is ''funga''. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reptiles Of The United States
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates ( lizards and snakes) and rhynchocephalians ( tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles origina ...

Turtles Of North America
Turtles are an order of reptiles known as Testudines, characterized by a special shell developed mainly from their ribs. Modern turtles are divided into two major groups, the Pleurodira (side necked turtles) and Cryptodira (hidden necked turtles), which differ in the way the head retracts. There are 360 living and recently extinct species of turtles, including land-dwelling tortoises and freshwater terrapins. They are found on most continents, some islands and, in the case of sea turtles, much of the ocean. Like other amniotes (reptiles, birds, and mammals) they breathe air and do not lay eggs underwater, although many species live in or around water. Turtle shells are made mostly of bone; the upper part is the domed carapace, while the underside is the flatter plastron or belly-plate. Its outer surface is covered in scales made of keratin, the material of hair, horns, and claws. The carapace bones develop from ribs that grow sideways and develop into broad flat plates ...

Apalone
''Apalone'' is a genus of turtles in the family Trionychidae. Species of ''Apalone'' are native to North America. Geographic range Most ''Apalone'' species are restricted to the United States, though the range of the spiny softshell, ''A. spinifera'', extends into southern Canada and northern Mexico. Taxonomy ''Apalone'' is a fairly new classification, resurrected by Meylan in 1987, assigned to North American species of the genus ''Trionyx''. They are still listed as ''Trionyx'' in some texts. (''Trionyx'' now refers specifically to certain softshell species found mainly in Africa.) Sexual dimorphism Turtles of the genus ''Apalone'' exhibit marked sexual dimorphism. In carapace length, females grow to about twice the size of males. In males, the claws on the front feet are longer than those on the back feet, but in females, the claws on the back feet are longer. In males, the stout tail extends well beyond the posterior edge of the carapace, but in females, the relatively thinn ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roger Conant (herpetologist)
Roger Conant (May 6, 1909 – December 19, 2003) was an American herpetologist, author, educator and conservationist. He was Director Emeritus of the Philadelphia Zoo and adjunct professor at the University of New Mexico. He wrote one of the first comprehensive field guides for North American reptiles in 1958 entitled: ''A Field Guide to Reptiles and Amphibians of Eastern and Central North America'', in the Peterson Field Guide series. Biography Born in Mamaroneck, New York, Conant lost his father when he was young. When he was a teenager he took a job at a local zoo to help his mother make ends meet, which, along with participating in the Boy Scouts of America, began his lifelong passion for reptiles. He was the first Eagle Scout in Monmouth County Council, New Jersey in 1924. He moved to Toledo, Ohio in 1929 and worked as Curator of Reptiles, and later General Curator at the Toledo Zoo from 1929 to 1935. In 1935 he returned to Philadelphia and became the Curator of Reptiles at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Taxonomy (biology), taxonomists, with varying participation by individual participants over the years, some dropping out and others joining. 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 and IUCN Red List status of each species as applicable.

Zoology
Zoology ()The pronunciation of zoology as is usually regarded as nonstandard, though it is not uncommon. is the branch of biology that studies the animal kingdom, including the structure, embryology, evolution, classification, habits, and distribution of all animals, both living and extinct, and how they interact with their ecosystems. 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 made use of 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. The Greek physician Galen studied human anatomy and was one of the greatest surgeons of the ancient world, but after the fall of the Western Roman Empire ...

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 Pymatuning Reservoir is a man-made lake in Crawford County, Pennsylvania and Ashtabula County, Ohio in the United States, on land that was once a very large ...
