Bufo Boreas 10565
''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.

Montane
Montane ecosystems are found on the slopes of mountains. The alpine climate in these regions strongly affects the ecosystem because temperatures fall as elevation increases, causing the ecosystem to stratify. This stratification is a crucial factor in shaping plant community, biodiversity, metabolic processes and ecosystem dynamics for montane ecosystems. Dense montane forests are common at moderate elevations, due to moderate temperatures and high rainfall. At higher elevations, the climate is harsher, with lower temperatures and higher winds, preventing the growth of trees and causing the plant community to transition to montane grasslands, shrublands or alpine tundra. Due to the unique climate conditions of montane ecosystems, they contain increased numbers of endemic species. Montane ecosystems also exhibit variation in ecosystem services, which include carbon storage and water supply. Life zones As elevation increases, the climate becomes cooler, due to a decrease in a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 Californi ...

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 ...

Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residues. Proteins perform a vast array of functions within organisms, including catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells and organisms, and transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the nucleotide sequence of their genes, and which usually results in protein folding into a specific 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called peptides. The individual amino acid residues are bonded together by peptide bonds and adjacent amino acid residues. The sequence of amino acid residue ...

Hibernate
Hibernation is a state of minimal activity and metabolic depression undergone by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It most commonly occurs during winter months. Although traditionally reserved for "deep" hibernators such as rodents, the term has been redefined to include animals such as bears and is now applied based on active metabolic suppression rather than any absolute decline in body temperature. Many experts believe that the processes of daily torpor and hibernation form a continuum and utilise similar mechanisms. The equivalent during the summer months is aestivation. Hibernation functions to conserve energy when sufficient food is not available. To achieve this energy saving, an endothermic animal decreases its metabolic rate and thereby its body temperature. Hibernation may last days, weeks, or months—depending on the species, ambient temperat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Breeding In The Wild
Breeding in the wild is the natural process of animal reproduction occurring in the natural habitat of a given species. This terminology is distinct from animal husbandry or breeding of species in captivity. Breeding locations are often chosen for very specific requirements of shelter and proximity to food; moreover, the breeding season is a particular time window that has evolved for each species to suit species anatomical, mating-ritual, or climatic and other ecological factors. Many species migrate considerable distances to reach the requisite breeding locations. Certain common characteristics apply to various taxa within the animal kingdom, which traits are often sorted among amphibians, reptiles, mammals, avafauna, arthropods and lower life forms. Amphibians For many amphibians, an annual breeding cycle applies, typically regulated by ambient temperature, precipitation, availability of surface water and food supply. This breeding season is accentuated in temperate regions, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...
