Northern America
Northern America is the northernmost subregion of North America. The boundaries may be drawn slightly differently. In one definition, it lies directly north of Middle America (including the Caribbean and Central America).Gonzalez, Joseph. 2004"Northern America: Land of Opportunity"(ch. 6). ''The Complete Idiot's Guide to Geography.'' () New York: Alpha Books; pp. 57–8 Northern America's land frontier with the rest of North America then coincides with the Mexico–United States border. Geopolitically, according to the United Nations' scheme of geographical regions and subregions, Northern America consists of Bermuda, Canada, Greenland, Saint Pierre and Miquelon and the United States (the contiguous United States and Alaska only, excluding Hawaii, Navassa Island, Puerto Rico, the United States Virgin Islands, and other minor U.S. Pacific territories). From a geographical perspective, Mexico would also be part of Northern America as it is on the same land as the United State ...

Taricha Rivularis
The red-bellied newt (''Taricha rivularis'') is a newt that is native to coastal woodlands in northern California and is terrestrial for most of its life. Description When full grown, the red-bellied newt measures between from its nose to its vent, and between from its nose to its tail. It has grainy skin, and is brownish-black on top with a tomato-red underbelly.Californiaherps.co''Taricha rivularis – Red-bellied Newt'' californiaherps.com The male red-bellied newt often has a dark, broad coloring across the vent, while females do not. Breeding males develop smooth skin and a flattened tail. The red-bellied newt can be distinguished from other coastal newts by its red belly and a lack of yellow in its eyes. Distribution and habitat The red-bellied newt is found in California along the coast from Bodega in Sonoma County, inland to Lower Lake, and north to Honeydew, Humboldt County.Stebbins, Robert C.; ''Amphibians and Reptiles of California''; University of California Pres ...

Aneides Flavipunctatus
The speckled black salamander (''Aneides flavipunctatus''), previously known as just the black salamander, is a species of salamander in the family Plethodontidae. It is endemic to the U.S. state of California. Its natural habitats are temperate forests and temperate grassland. It is threatened by habitat loss. Taxonomy Previously, it was referred to as the black salamander, and was thought to have a fragmented range across most of California and southern Oregon. However, a 2019 taxonomic study found it to represent a species complex of multiple species: the speckled black salamander (''A. flavipunctatus sensu stricto''), the Shasta black salamander (''A. iecanus''), the Santa Cruz black salamander (''A. niger''), and the Klamath black salamander (''A. klamathensis''). These were thus split off as distinct species. Description The speckled black salamander can grow to long. The color varies, black with coarse can be the color or fine white spots, black with yellow spots, o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aneides Ferreus
The clouded salamander (''Aneides ferreus'') is a species of salamander in the family Plethodontidae. It is endemic to the Pacific Northwest. Its natural habitat is temperate forests and it is probable that many nest in trees. It is threatened by habitat loss. Description The clouded salamander can grow to about total length. It is long and slim with relatively long legs, square ends to its toes and a prehensile tail. It has two naso-labial grooves joining its nostrils to its mouth and sixteen costal grooves down its flank. The upper side is pale grey variously blotched with gold, olive green or dull red. The juvenile has a brass-colored streak down the center of its back. Distribution and habitat The clouded salamander is found in the Cascadian bioregion of North America at heights up to . Its range extends from the Columbia River southwards through the Cascade Mountains, along the Oregon coast to the northern tip of California in Del Norte County. It lives in forested areas ...

Aneides Caryaensis
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 Hicko ...

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 considered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydromantes Wintu
The Wintu Shasta salamander (''Hydromantes wintu'') is a species of salamander in the family Plethodontidae. It is endemic to Shasta County in California. Taxonomy It was previously thought to be a population of the Shasta salamander (''H. shastae'') and is not physically distinguishable, but a 2018 phylogenetic study found it to be a genetically distinct species. It is named in honor of the Winnemem Wintu people who originally inhabited the area until being displaced by early European settlers, and had many of their cultural sites inundated by Shasta Lake. Distribution It is found in a very small area on the McCloud River arm on the north shore of Shasta Lake, near the vicinity of the former Shasta Iron Mine. Habitat Its distribution was likely fragmented by the creation of the lake and the construction of the Shasta Dam. Proposals to raise the water levels of the lake would likely flood more habitats and further threaten it. However, in 2021 the U.S. Fish and Wildlife ...

Hydromantes Shastae
The Shasta salamander (''Hydromantes shastae'') is a species of salamander in the family Plethodontidae. It is endemic to Shasta County in California. Taxonomy Formerly considered to be a single species with a rather small distribution in the vicinity of Shasta Lake, a 2018 study found it to comprise three species, including ''H. shastae sensu stricto'', and two new species: the Samwel Shasta salamander (''H. samweli''), found in the north-central and northwest sides of the lake, and the Wintu Shasta salamander (''H. wintu'') on the northern shore of the lake near the McCloud River. Both species are physically similar to ''H. shastae'' and can only be distinguished by range and genetics. Distribution and habitat It is found in the Cascade Range in areas around Shasta Lake with limestone substrate, primarily between Squaw Creek and the Pit River, but also on the south side of Shasta Lake and in the vicinity of Ingot. Its natural habitats are temperate forests, freshwater s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydromantes Samweli
The Samwel Shasta salamander (''Hydromantes samweli'') is a species of salamander in the family Plethodontidae. It is endemic to Shasta County in California. Taxonomy It was previously thought to be a population of the Shasta salamander (''H. shastae'') and is not physically distinguishable, but a 2018 phylogenetic study found it to be a genetically distinct species. It is named after its type locality, Samwel Cave, which originates from ''Sa-Wal'', the Wintu name for grizzly bear. Distribution It is found in a fairly small area around the north-central and northwest sides of Shasta Lake, but possibly extending 20 km further to the west. Threats Its distribution was likely fragmented by the creation of the lake and the construction of the Shasta Dam. Proposals to raise the water levels would likely flood more habitats and further threaten it. However, in 2021 the U.S. Fish and Wildlife Service found the species to not warrant Endangered Species Act The Endanger ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plethodontinae
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] |
