Japanese Pond Turtle
The Japanese pond turtle (''Mauremys japonica''), also called commonly the Japanese pond terrapin and the Japanese pond tortoise, is a species of turtle in the family Geoemydidae endemic to Japan. Its Japanese name is ''nihon ishigame'', Japanese stone turtle. Its population has decreased somewhat due to habitat loss, but it is not yet considered a threatened species. This species is known to hybridize with the Chinese pond turtle ''Mauremys reevesii'', commonly known as the Chinese pond turtle, the Chinese three-keeled pond turtle, or Reeves' turtle, is a species of turtle in the family (biology), family Geoemydidae, a family which was formerly called Bataguridae. The sp ..., the Chinese stripe-necked turtle, and the Chinese box turtle (and possibly other Geoemydidae) in captivity. As these three species are much rarer and strongly declining in the wild, this should be avoided. The Japanese pond turtle is an aquatic species found in many freshwater bodies of water. Thes ...

Coenraad Jacob Temminck
Coenraad Jacob Temminck (; 31 March 1778 – 30 January 1858) was a Dutch people, Dutch patrician, Zoology, zoologist and museum director. Biography Coenraad Jacob Temminck was born on 31 March 1778 in Amsterdam in the Dutch Republic. From his father, Jacob Temminck, who was treasurer of the Dutch East India Company with links to numerous travellers and collectors, he inherited a large collection of bird specimens. His father was a good friend of Francois Levaillant who also guided Coenraad. Temminck's ''Manuel d'ornithologie, ou Tableau systématique des oiseaux qui se trouvent en Europe'' (1815) was the standard work on European birds for many years. He was also the author of ''Histoire naturelle générale des Pigeons et des Gallinacées'' (1813–1817), illustrated by Pauline Rifer de Courcelles, Pauline Knip. He wrote ''Nouveau Recueil de Planches coloriées d'Oiseaux'' (1820–1839), and contributed to the mammalian sections of Philipp Franz von Siebold's ''Fauna jap ...

Threatened Species
A threatened species is any species (including animals, plants and fungi) which is vulnerable to extinction in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of ''critical depensation'', a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment without direct reference to human activity. IUCN definition The International Union for Conservation of Nature (IUCN) is the foremost authority on threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened: *Vulnerable species *Endangered species *Critically endangered species Less-than-threatened categories are near threatened, least concern, and the no longer assigned category of conservation dependent. Species that have not been evaluated (NE), or do not have sufficient data ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Endemic Reptiles Of Japan
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Chinese Box Turtle
The Chinese box turtle (), also known as the yellow-margined box turtle, or golden-headed turtle, is a species of Asian box turtle. Taxonomy (biology), Taxonomically, it is called ''Cuora flavomarginata''. Anatomy ''C. flavomarginata'' has a highly domed shell, the carapace and plastron of which are a dark brown with a cream-yellow stripe on the vertebral keel. The edge of the plastron is lightly pigmented due to the marginal scutes' and plastral scutes' lighter pigmentation near their edges. The skin on the limbs is brown, while the top of the head is pale green. Each side of the head has a yellow line extending from behind the eye backward. The skin beneath the head and between the limbs is a lighter pinkish color. The name ''box turtle'' refers to ''C. flavomarginatas ability to bring the plastron to the edges of the carapace. This is enabled by a hinge on the plastron and ligaments connecting the carapace and plastron, which allows for limited movement. The forefeet have fi ...

Chinese Stripe-necked Turtle
The Chinese stripe-necked turtle (''Mauremys sinensis'') or golden thread turtle, is a species of turtle in the family Geoemydidae. They are widely distributed in the subtropical regions of Taiwan. Like many other Geoemydidae, this species hybridizes vigorously with related and not-so-closely related members of its family. It is one of the two most commonly found species used for divination that have been recovered from Shang dynasty sites, despite the Shang capital being over 1000 km north of its modern-day distribution range.Keightley (1979), see especially pp. 160, 189-194. Description Chinese-stripe-necked turtles have a green body. As a juvenile, its carapace is grayish green and there are three distinctive ridges. As an adult, the color fades to a brown color and the two ridges gradually disappear. The plastron is ivory in color with small black spots. The male's tail is more coarse and long, while adult females will be larger than the males. Habitat Chinese strip ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinese Pond Turtle
''Mauremys reevesii'', commonly known as the Chinese pond turtle, the Chinese three-keeled pond turtle, or Reeves' turtle, is a species of turtle in the family (biology), family Geoemydidae, a family which was formerly called Bataguridae. The species is native to East Asia. It is one of the two most commonly found species used for Oracle bone#Shang divination, divination that have been recovered from Shang dynasty sites. Description While the species typically appears to have a brown shell, dark grey skin, with yellow markings on the neck and yellow irises, melanism is well documented in males, where the entirety of the animal including the eyes becomes completely black and the yellow markings are lost. Melanism only occurs in mature males over 7 years old. Old females may sometimes also develop darker shells and fewer markings. Certain populations of Reeve's turtles may exhibit Turtle#Megacephaly, megacephaly. Megacephalic turtles have much larger and broader heads, and hype ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different varieties, subspecies, species or genera through sexual reproduction. Generally, it means that each cell has genetic material from two different organisms, whereas an individual where some cells are derived from a different organism is called a chimera. Hybrids are not always intermediates between their parents such as in blending inheritance (a now discredited theory in modern genetics by particulate inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridization, which include genetic and morph ...

Habitat Loss
Habitat destruction (also termed habitat loss or habitat reduction) occurs when a natural habitat is no longer able to support its native species. The organisms once living there have either moved elsewhere, or are dead, leading to a decrease in biodiversity and Abundance (ecology), species numbers. Habitat destruction is in fact the leading cause of biodiversity loss and species extinction worldwide. Humans contribute to habitat destruction through the Exploitation of natural resources, use of natural resources, agriculture, industrial production and urbanization (urban sprawl). Other activities include mining, logging and trawling. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, introduced species, introduction of invasive species, ecosystem nutrient depletion, water pollution, water and noise pollution are some examples. Loss of habitat can be preceded by an initial habitat fragmentation. Fragmentation and lo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Name
In biology, a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life; and is often contrasted with the scientific name for the same organism, which is often based in Latin. A common name is sometimes frequently used, but that is not always the case. In chemistry, IUPAC defines a common name as one that, although it unambiguously defines a chemical, does not follow the current systematic naming convention, such as acetone, systematically 2-propanone, while a vernacular name describes one used in a lab, trade or industry that does not unambiguously describe a single chemical, such as copper sulfate, which may refer to either copper(I) sulfate or copper(II) sulfate. Sometimes common names are created by authorities on one particular subject, in an attempt to make it possible for members of the general public (including s ...
