Squamata
Squamata (, Latin ''squamatus'', 'scaly, having scales') is the largest order of reptiles, comprising lizards, snakes, and amphisbaenians (worm lizards), which are collectively known as squamates or scaled reptiles. With over 10,900 species, it is also the second-largest order of extant (living) vertebrates, after the perciform fish. Members of the order are distinguished by their skins, which bear horny scales or shields, and must periodically engage in molting. They also possess movable quadrate bones, making possible movement of the upper jaw relative to the neurocranium. This is particularly visible in snakes, which are able to open their mouths very wide to accommodate comparatively large prey. Squamata is the most variably sized order of reptiles, ranging from the dwarf gecko (''Sphaerodactylus ariasae'') to the Reticulated python (''Malayopython reticulatus'') and the now-extinct mosasaurs, which reached lengths over . Among other reptiles, squamates are most close ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Diadophis Punctatus Edwardsii
''Diadophis punctatus edwardsii'', commonly known as the northern ringneck snake, is a subspecies of ''Diadophis punctatus'', a snake in the family Colubridae. The subspecies is endemic to North America. Etymology The subspecific name, ''edwardsii'', is in honor of English ornithologist George Edwards, who described it, without giving it a binomial name, from a specimen he had received from William Bartram. Description The northern ringneck snake has a body color from bluish grey to black, with a complete narrow yellow or orange ring around its neck and an underside matching the ring and generally lacking any dark spotting or patterning. The complete ring and lack of large dark spots on the belly differentiate it from other subspecies of ''D. punctatus''. In some regions, there are areas of intergradation with other subspecies. Generally from in total length (including tail) as an adult, it can reach more than two feet (61 cm) in length. Conant R (1975). ''A Field ...

Alberta
Alberta ( ) is one of the thirteen provinces and territories of Canada. It is part of Western Canada and is one of the three prairie provinces.

Local Extinction
Local extinction, also known as extirpation, refers to a species (or other taxon) of plant or animal that ceases to exist in a chosen geographic area of study, though it still exists elsewhere. Local extinctions are contrasted with global extinctions. Local extinctions mark a change in the ecology of an area. In recent times, local extinction has sometimes been followed by a replacement of the species taken from other locations; wolf reintroduction is an example of this. The term "local extinction" is highly vernacular. The more proper biological term is ''extirpation''. Discussion Glaciation can lead to local extinction. This was the case during the Pleistocene glaciation event in North America. During this period, most of the native North American species of earthworm were killed in places covered by glaciation. This left them open for colonization by European earthworms brought over in soil from Europe. Species naturally become extirpated from islands over time. The number ...
