List Of Mammals Of Germany
This list shows the IUCN Red List status of mammal species recorded in Germany. One of them is critically endangered, three are endangered, and several are near threatened. One of the species listed for Germany can no longer be found in the wild. The following tags are used to highlight each species' IUCN Red List status as published by the International Union for Conservation of Nature: Order: Rodentia (rodents) Rodents make up the largest order of mammals, with over 40% of mammalian species. They have two incisors in the upper and lower jaw which grow continually and must be kept short by gnawing. Most rodents are small though the capybara of South America can weigh up to . *Suborder: Sciurognathi **Family: Castoridae (beavers) ***Genus: '' Castor'' **** American beaver, ''C. canadensis'' introduced **** Eurasian beaver, ''C. fiber'' **Family: Sciuridae (squirrels) ***Subfamily: Sciurinae ****Tribe: Sciurini *****Genus: ''Sciurus'' ****** Red squirrel, ''S. vulgaris'' ...

IUCN Red List
The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is the world's most comprehensive inventory of the global conservation status of biological species. It uses a set of precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. With its strong scientific base, the IUCN Red List is recognized as the most authoritative guide to the status of biological diversity. A series of Regional Red Lists are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The aim of the IUCN Red List is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to reduce species extinction. According to IUCN the formally stated goals of the Red List are to provi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beaver
Beavers are large, semiaquatic rodents in the genus ''Castor'' native to the temperate Northern Hemisphere. There are two extant species: the North American beaver (''Castor canadensis'') and the Eurasian beaver (''C. fiber''). Beavers are the second-largest living rodents after the capybaras. They have stout bodies with large heads, long chisel-like incisors, brown or gray fur, hand-like front feet, webbed back feet and flat, scaly tails. The two species differ in the shape of the skull and tail and fur color. Beavers can be found in a number of freshwater habitats, such as rivers, streams, lakes and ponds. They are herbivorous, consuming tree bark, aquatic plants, grasses and sedges. Beavers build dams and lodges using tree branches, vegetation, rocks and mud; they chew down trees for building material. Dams impound water and lodges serve as shelters. Their infrastructure creates wetlands used by many other species, and because of their effect on other organisms in the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alpine Marmot
The alpine marmot (''Marmota marmota'') is a large ground-dwelling squirrel, from the genus of marmots. It is found in high numbers in mountainous areas of central and southern Europe, at heights between in the Alps, Carpathians, Tatras and Northern Apennines. In 1948 they were reintroduced with success in the Pyrenees, where the alpine marmot had disappeared at end of the Pleistocene epoch. Evolution The alpine marmot originates as an animal of Pleistocene cold steppe, exquisitely adapted to this ice-age climate. As such, alpine marmots are excellent diggers, able to penetrate soil that even a pickaxe would have difficulty with, and spend up to nine months per year in hibernation. Since the disappearance of the Pleistocene cold steppe, the alpine marmot persists in the high altitude alpine meadow. During the colonisation of Alpine habitat, the alpine marmot has lost most of its genetic diversity through a bottleneck effect. It could not rebuild its genetic diversity eve ...

Xerinae
The Xerinae comprise a subfamily of squirrels, many of which are highly terrestrial. It includes the tribes Marmotini (marmots, chipmunks, prairie dogs, and other Holarctic ground squirrels), Xerini (African and some Eurasian ground squirrels), and Protoxerini (African tree squirrels).Thorington, R. W. and R. S. Hoffmann (2005). "Family Sciuridae". pp. 754–818 in Wilson, E. D. and Reeder, D. M. (eds.), Mammal Species of the World: A Taxonomic and Geographic Reference', Vol. 2.

Red Squirrel
The red squirrel (''Sciurus vulgaris'') is a species of tree squirrel in the genus ''Sciurus'' common throughout Europe and Asia. The red squirrel is an arboreal, primarily herbivorous rodent. In Great Britain, Ireland, and in Italy numbers have decreased drastically in recent years. This decline is associated with the introduction by humans of the eastern grey squirrel (''Sciurus carolinensis'') from North America. However, the population in Scotland is stabilising due to conservation efforts, awareness and the increasing population of the pine marten, a European predator that selectively controls grey squirrels. Description The red squirrel has a typical head-and-body length of , a tail length of , and a mass of . Males and females are the same size. The red squirrel is somewhat smaller than the eastern grey squirrel which has a head-and-body length of and weighs between . The long tail helps the squirrel to balance and steer when jumping from tree to tree and running ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sciurus
The genus ''Sciurus'' contains most of the common, bushy-tailed squirrels in North America, Europe, temperate Asia, Central America and South America. Species The number of species in the genus is subject to change. In 2005, Thorington & Hoffman- whose taxonomic interpretation is followed by the IUCN website- accepted 28 species in the genus: Genus ''Sciurus'' *Subgenus ''Sciurus'' **Allen's squirrel, ''Sciurus alleni'' **Arizona gray squirrel, ''Sciurus arizonensis'' **Mexican gray squirrel, ''Sciurus aureogaster'' **Eastern gray squirrel, ''Sciurus carolinensis'' **Collie's squirrel, ''Sciurus colliaei'' **Deppe's squirrel, ''Sciurus deppei'' **Japanese squirrel, ''Sciurus lis'' **Calabrian black squirrel, ''Sciurus meridionalis'' **Mexican fox squirrel, ''Sciurus nayaritensis'' **Fox squirrel, ''Sciurus niger'' ** Peters's squirrel, ''Sciurus oculatus'' **Variegated squirrel, ''Sciurus variegatoides'' **Eurasian red squirrel, ''Sciurus vulgaris'' **Yucatan squirrel, ''Sciur ...

Sciurini
Sciurini is a tribe (taxonomy), tribe that includes about forty species of squirrels,Thorington and Hoffmann, 2005, p. 754 mostly from the Americas. It includes five living genera—the American dwarf squirrels, ''Microsciurus''; the Bornean ''Rheithrosciurus''; the widespread American and Eurasian tree squirrels of the genus ''Sciurus'', which includes some of the best known squirrel species; the Central American ''Syntheosciurus''; and the American pine squirrels, ''Pine squirrel, Tamiasciurus''. Like other arboreal squirrels, they are sometimes referred to as tree squirrels. Taxonomy The name "Sciurini" was first employed by Hermann Burmeister in 1854, who used it for the entire squirrel family. In his influential 1945 classification of mammals, George Gaylord Simpson included four genus, genera of squirrels in Sciurini, which he recognized as one of eight tribe (taxonomy), tribes within the subfamily Sciurinae (including all squirrels except the flying squirrels): ''Sciuru ...

Sciurinae
Sciurinae is a subfamily of squirrels (in the family Sciuridae), uniting the flying squirrels with certain related tree squirrels. Older sources place the flying squirrels in a separate subfamily (Pteromyinae) and unite all remaining sciurids into the subfamily Sciurinae, but this has been strongly refuted by genetic studies.
