This list shows the IUCN Red List status of the 93 mammal species occurring in Portugal. One of them is critically endangered, three are endangered, eleven are vulnerable, and one is near threatened. The following tags are used to highlight each species' status as assessed on the respective IUCN Red List 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. *Suborder: Sciurognathi **Family: Sciuridae (squirrels) ***Subfamily: Sciurinae ****Genus: ''Sciurus'' ***** Red squirrel, ''S. vulgaris'' **Family: Gliridae (dormice) ***Subfamily: Leithiinae ****Genus: ''Eliomys'' ***** Garden dormouse, ''E. quercinus'' **Family: Cricetidae (hamsters, voles, lemmings) ***Subfamily: Arvicolinae ****Genus: ''Arvicola'' *****Southwestern water vole, ''A. sapidus ...

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] |
Sciurus
The genus ''Sciurus'' contains most of the common, bushy-tailed squirrels in North America, Europe, temperate Asia, Central America and South America.

Field Vole
The short-tailed field vole, short-tailed vole, or simply field vole (''Microtus agrestis'') is a grey-brown vole, around 10 cm in length, with a short tail. It is one of the most common mammals in Europe, with a range extending from the Atlantic coast to Lake Baikal. These voles are found in moist grassy habitats, such as woodland, marsh or on river banks. Although they make shallow burrows, they usually build nests above ground. They are an important food source for owls and some other predators and their population size tends to peak and trough cyclically. Field voles breed prolifically, mainly in summer, but often all year round, even under snow. Females produce up to seven litters a year, each averaging from four to six young which are weaned after about fourteen days. The short-tailed field vole is both widespread and common and is listed as being of "Least Concern" by the IUCN. Description The short-tailed field vole is a small, dark brown rodent with a short tail, dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cabrera's Vole
Cabrera's vole (''Microtus cabrerae'') is a species of vole native to Spain and Portugal. It is named for Ángel Cabrera, a mammalogist then working at the Museo Nacional de Ciencias Naturales in Madrid. It is the only living member of the subgenus ''Iberomys'', although two fossil species are also known, including ''M. brecciensis'', the likely direct ancestor of the living species. Description Cabrera's vole is one of the largest voles in the genus ''Microtus'', with a body length of and a tail in length. Adults weigh between , up to five times more than other voles native to Spain and Portugal. They have long, thick fur which is brownish olive over most of the body and yellowish in colour on the underparts. The guard hairs are particularly long, reaching as far as out from the body, greater than that in any other ''Microtus'' species. Internally, the caecum is longer than that in most other voles, relative to body size, a feature that may be related to its specialised diet. ...
