Bufo Boreas 10562
''Bufo'' is a genus of true toads in the amphibian family Bufonidae. As traditionally defined, it was a wastebasket genus containing a large number of toads from much of the world, but following taxonomic reviews most of these have been moved to other genera, leaving only seventeen extant (living) species from Europe, northern Africa and Asia in this genus, including the well-known common toad (''B. bufo''). Some of the genera that contain species formerly placed in ''Bufo'' are '' Anaxyrus'' (many North American species), '' Bufotes'' ( European green toad and relatives), '' Duttaphrynus'' (many Asian species, including the Asian common toad introduced elsewhere), ''Epidalea The natterjack toad (''Epidalea calamita'') is a toad native to sandy and heathland areas of Europe.

Cheatgrass
''Bromus tectorum'', known as downy brome, drooping brome or cheatgrass, is a winter annual grass native to Europe, southwestern Asia, and northern Africa, but has become invasive in many other areas. It now is present in most of Europe, southern Russia, Japan, South Africa, Australia, New Zealand, Iceland, Greenland, North America and western Central Asia. In the eastern US ''B. tectorum'' is common along roadsides and as a crop weed, but usually does not dominate an ecosystem. It has become a dominant species in the Intermountain West and parts of Canada, and displays especially invasive behavior in the sagebrush steppe ecosystems where it has been listed as noxious weed. ''B. tectorum'' often enters the site in an area that has been disturbed, and then quickly expands into the surrounding area through its rapid growth and prolific seed production. The reduction of native plants and the increased fire frequency caused by ''B. tectorum'' prompted the United States Fish and Wil ...

Newt
A newt is a salamander in the subfamily Pleurodelinae. The terrestrial juvenile phase is called an eft. Unlike other members of the family Salamandridae, newts are semiaquatic, alternating between aquatic and terrestrial habitats. Not all aquatic salamanders are considered newts, however. More than 100 known species of newts are found in North America, Europe, North Africa and Asia. Newts metamorphose through three distinct developmental life stages: aquatic larva, terrestrial juvenile (eft), and adult. Adult newts have lizard-like bodies and return to the water every year to breed, otherwise living in humid, cover-rich land habitats. Newts are threatened by habitat loss, fragmentation and pollution. Several species are endangered, and at least one species, the Yunnan lake newt, has become extinct recently. Etymology The Old English name of the animal was , (of unknown origin), resulting in Middle English ; this word was transformed irregularly into , , or . The initial "n ...

Rough-skinned Newt
The rough-skinned newt or roughskin newt (''Taricha granulosa'') is a North American newt known for the strong toxin exuded from its skin. Appearance A stocky newt with rounded snout, it ranges from light brown to olive or brownish-black on top, with the underside, including the head, legs, and tail, a contrasting orange to yellow. The skin is granular, but males are smooth-skinned during breeding season. They measure 6 to 9 cm in snout-to-vent length, and 11 to 18 cm overall. They are similar to the California newt (''Taricha torosa'') but differ in having smaller eyes, yellow irises, V-shaped tooth patterns, and uniformly dark eyelids. Males can be distinguished from females during breeding season by large swollen vent lobes and cornified toe pads. Distribution and subspecies Habitats of rough-skinned newts are found throughout the Pacific Northwest. Their range extends south to Santa Cruz, California, and north to Alaska. They are uncommon east of the Cascade ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Extant Taxon
Neontology is a part of biology that, in contrast to paleontology, deals with living (or, more generally, '' recent'') organisms. It is the study of extant taxa (singular: extant taxon): taxa (such as species, genera and families) with members still alive, as opposed to (all) being extinct. For example: * The moose (''Alces alces'') is an extant species, and the dodo (''Raphus cucullatus'') is an extinct species. * In the group of molluscs known as the cephalopods, there were approximately 600 extant species and 7,500 extinct species. A taxon can be classified as extinct if it is broadly agreed or certified that no members of the group are still alive. Conversely, an extinct taxon can be reclassified as extant if there are new discoveries of living species ("Lazarus species"), or if previously-known extant species are reclassified as members of the taxon. Most biologists, zoologists, and botanists are in practice neontologists, and the term neontologist is used large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plethodontidae
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] |
Salmon River (Idaho)
The Salmon River, also known as "The River of No Return", is a river located in the U.S. state of Idaho in the western United States. It flows for through central Idaho, draining a rugged, thinly populated watershed of . The river drops more than from its headwaters, near Galena Summit above the Sawtooth Valley in the Sawtooth National Recreation Area, to its confluence with the Snake River. Measured at White Bird, its average discharge is . The Salmon River is the longest undammed river in the contiguous United States and the longest within a single state outside Alaska. Settlements located along the Salmon River include Stanley, Clayton, Challis, Salmon, Riggins, and White Bird. Redfish Lake and Little Redfish Lake, which flow into the river via Redfish Lake Creek, are the termini of the longest Pacific sockeye salmon migration in North America. The lower half of the river provides the time zone boundary for the state, with northern Idaho on Pacific Time an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coastal Giant Salamander
The coastal giant salamander (''Dicamptodon tenebrosus'') is a species of salamander in the family Dicamptodontidae (Pacific giant salamanders). It is endemic to the Pacific Northwest of North America. There are three closely related species to this taxon: ''D. ensatus'' (California giant salamander), ''D. copei'' ( Cope's giant salamander), and ''D. aterrimus'' ( Idaho giant salamander). Description The coastal giant salamander can reach up to 34 cm (13 inches) in total length, making it the largest terrestrial salamander in North America. The coastal giant salamander has stout limbs with four toes on the front feet and five toes on the back feet. The species tail is around 40 percent of the total length of the salamander and is laterally compressed. The head, back, and sides have a marbled or reticulate pattern of dark blotches on a light brown or brassy-colored background. The head is broad with a shovel-like snout and a fold of skin across the throat called the gular ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cope's Giant Salamander
Cope's giant salamander (''Dicamptodon copei'') is a species of salamander in the family Dicamptodontidae, the Pacific giant salamanders.Behler, J. L. and F. W. King. (1979) ''National Audubon Society Field Guide to Reptiles and Amphibians'', Knopf, It is native to Washington and Oregon in the Pacific Northwest region of the United States. Description This species up to 19.5 centimeters in length. It exhibits neoteny rarely undergoing metamorphosis to the adult form, and it resembles the larvae of similar salamander species. It usually becomes sexually, but not physically, mature. It is gold and brown in color. The costal grooves are inconspicuous. It has a rounded snout and the laterally compressed, finlike tail of a typical larva. It retains its gills.Hallock, L. A. and McAllister, K. R. 2009Cope's Giant Salamander. Washington Herp Atlas.

California Giant Salamander
The California giant salamander (''Dicamptodon ensatus'') is a species of salamander in the family Ambystomatidae. ''Dicamptodon ensatus'' is endemic to California, in the western United States. The species once additionally included individuals now belonging to the species ''D. aterrimus'' (Idaho giant salamander) and ''D. tenebrosus'' ( coastal giant salamander), under the common name Pacific giant salamander, which now refers to the genus and family. Taxonomy The Pacific giant salamander (''D. ensatus'') was thought to consist of three geographic populations, an Idaho isolates, a group in northern California, and a group in Oregon and Washington. In 1989 genetic studies showed that the ''D. ensatus'' populations consisted of three species: the Idaho giant salamander (''Dicamptodon aterrimus'') in Idaho, and two highly divergent species with a narrow hybrid zone in California, the coastal giant salamander (''Dicamptodon tenebrosus'') (ranging from northern California to Washi ...

Idaho Giant Salamander
The Idaho giant salamander, ''Dicamptodon aterrimus'', is a species of salamander. There are three closely related species to this taxon: ''D. ensatus'', (California giant salamander), ''D. copei'' (Cope's giant salamander) and ''D. tenebrosus'' (coastal giant salamander) also known as the (Pacific giant salamander). Description The Idaho giant salamander is the darkest and most intricately blotched of the giant salamanders. They vary between brown, purple, tan, grey, and a copperish color. Tiger salamanders and Idaho giant salamanders have superficial resemblance pertaining to size and shape, but the costal grooves and foot tubercles are significantly different between the two species. This salamander has a defining thick head and body and a fourth toe on the hind foot with only three segments. Adults are typically 20 cm (7.8 inches) in lengthRichard Cannings. 2007 but often vary between 7 and 11.75 inches long and may be observed around 13 inches at maximum le ...
