Aneides
Climbing salamanders is the common name for plethodontid (lungless) salamanders of the genus ''Aneides''. It contains 10 species native to North America, distributed between the Pacific Coast (7 species), Sacramento Mountains (1 species), and Appalachian Mountains (2 species). As their common name suggests, most of these species have prehensile tails and are quite mobile in trees. Taxonomy The green salamander (''A. aeneus'') and the Hickory Nut Gorge green salamander (''A. caryaensis'') are now considered to belong to their own subgenus ''Castaneides'', which diverged from the '' Aneides hardii'' lineage between 27.2 and 32.3 million years ago, during the Oligocene. ''Castaneides'' contains significant cryptic diversity and may contain more as-of-yet undescribed species. All other western ''Aneides'' including ''A. hardii'' are considered ''Aneides sensu stricto'', and belong to the subgenus of the same name. Distribution All ten known species in this genus inhabit mountain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aneides Aeneus
The green salamander (''Aneides aeneus'') is a species of lungless salamander in the family Plethodontidae. It and the Hickory Nut Gorge green salamander (''A. caryaensis'') are the only currently-described members of the genus ''Aneides'' that inhabit any areas in the eastern half of United States (all other ''Aneides'' salamanders are found west of the Mississippi River). Rarely seen in the field, the green salamander is an extremely habitat-specific species that is seldom found away from its preferred surroundings: moist, shaded rock crevices. Description and taxonomy The green salamander is small and notably flat. ''Aneides aeneus''‘ green, lichen-like blotches against a darker dorsum make it the only salamander in North America with green markings. ''A. aeneus'' possesses squared toe-tips, large, conspicuous eyes, and a light blue to yellow ventral surface. Adults range from 8–12 cm (3 to 5 in) with 14 to 15 costal grooves. ''Aeneus'' was formerly consi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hickory Nut Gorge Green Salamander
The Hickory Nut Gorge green salamander (''Aneides caryaensis'') is a species of lungless salamander in the family Plethodontidae. It is endemic to the Hickory Nut Gorge in the state of North Carolina in the United States. Taxonomy It is a member of the subgenus ''Castaneides'', which contains the only members of the genus ''Aneides'' that inhabit the eastern half of North America, including the green salamander (''Aneides aeneus'') and two undescribed taxa. It was formerly considered a population of the green salamander until a study in 2019 found it to represent a distinct species and described it as such. Based on genetic evidence, it is the most basal member of the subgenus ''Castaneides'', and forms a clade entirely distinct from the other three likely species in the subgenus. A distinct population of ''A. aeneus'' of the Blue Ridge Escarpment (possibly another ''Castaneides'' cryptic species) can be found just 25 km west of ''A. caryaensis'''s range in the Hickory ...

Sacramento Mountain Salamander
The Sacramento Mountain salamander (''Aneides hardii'') is a species of salamander in the family Plethodontidae. It is endemic to mountainous regions of New Mexico in the United States. Its natural habitat is temperate forests where it is threatened by habitat loss. Distribution and habitat The Sacramento Mountain salamander occurs in three separate mountainous areas in New Mexico, the Capitan Mountains, the Sierra Blanca range and the Sacramento Mountains. It is found at heights of at least above sea level in mixed forests. It typically occurs on north or east facing slopes among Douglas fir, Engelmann spruce and white fir, often with an understory of Rocky Mountain maple. It often hides in the leaf litter or rotten logs, under rocks, fallen branches or vegetation. Above the tree line it is found in stony areas with mosses and lichens. The only other salamander occurring in this area is the tiger salamander (''Ambystoma tigrinum'') and that is more of a lowland species and p ...

Prehensile Tail
A prehensile tail is the tail of an animal that has adapted to grasp or hold objects. Fully prehensile tails can be used to hold and manipulate objects, and in particular to aid arboreal creatures in finding and eating food in the trees. If the tail cannot be used for this it is considered only partially prehensile - such tails are often used to anchor an animal's body to dangle from a branch, or as an aid for climbing. The term ''prehensile'' means "able to grasp" (from the Latin ''prehendere'', to take hold of, to grasp). Evolution One point of interest is the distribution of animals with prehensile tails. The prehensile tail is predominantly a New World adaptation, especially among mammals. Many more animals in South America have prehensile tails than in Africa and Southeast Asia. It has been argued that animals with prehensile tails are more common in South America because the forest there is denser than in Africa or Southeast Asia. In contrast, less dense forests such as in S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lungless Salamander
Plethodontidae, or lungless salamanders, are a family of salamanders. Most species are native to the Western Hemisphere, from British Columbia to Brazil, although a few species are found in Sardinia, Europe south of the Alps, and South Korea. In terms of number of species, they are by far the largest group of salamanders. Biology Adult lungless salamanders have four limbs, with four toes on the fore limbs, and usually with five on the hind limbs. Within many species, mating and reproduction occur solely on land. Accordingly, many species also lack an aquatic larval stage, a phenomenon known as direct development in which the offspring hatch as fully-formed, miniature adults. Direct development is correlated with changes in the developmental characteristics of plethodontids compared to other families of salamanders including increases in egg size and duration of embryonic development. Additionally, the evolutionary loss of the aquatic larval stage is related to a diminishing dep ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

International Union For Conservation Of Nature
The International Union for Conservation of Nature (IUCN; officially International Union for Conservation of Nature and Natural Resources) is an international organization working in the field of nature conservation and sustainable use of natural resources. It is involved in data gathering and analysis, research, field projects, advocacy, and education. IUCN's mission is to "influence, encourage and assist societies throughout the world to conserve nature and to ensure that any use of natural resources is equitable and ecologically sustainable". Over the past decades, IUCN has widened its focus beyond conservation ecology and now incorporates issues related to sustainable development in its projects. IUCN does not itself aim to mobilize the public in support of nature conservation. It tries to influence the actions of governments, business and other stakeholders by providing information and advice and through building partnerships. The organization is best known to the wider pu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spencer Fullerton Baird
Spencer Fullerton Baird (; February 3, 1823 – August 19, 1887) was an American naturalist, ornithologist, ichthyologist, Herpetology, herpetologist, and museum curator. Baird was the first curator to be named at the Smithsonian Institution. He eventually served as assistant Secretary of the Smithsonian from 1850 to 1878, and as Secretary from 1878 until 1887. He was dedicated to expanding the natural history collections of the Smithsonian which he increased from 6,000 specimens in 1850 to over 2 million by the time of his death.

Green Salamanader From Breaks Interstate Park
Green is the color between cyan and yellow on the visible spectrum. It is evoked by light which has a dominant wavelength of roughly 495570 nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content. During post-classical and early modern Europe, green was the color commonly associated with wealth, merchants, bankers, and the gentry, whi ...
