Three are considered endangered, one is vulnerable, eight are listed as data deficient, and one has not yet been evaluated. [1] Domesticated species, such as the dogs formerly present, [2] are not ...
Although there are very few species, those that do inhabit Antarctica have high population densities. In the more extreme areas of the mainland, such as the cold deserts, food webs are sometimes restricted to three nematode species, only one of which is a predator . [ 13 ]
Bergmann's rule - Penguins on the Earth (mass m, height h) [1] Bergmann's rule is an ecogeographical rule that states that, within a broadly distributed taxonomic clade, populations and species of larger size are found in colder environments, while populations and species of smaller size are found in warmer regions.

Antarctica contains research stations and field camps that are staffed seasonally or year-round, and former whaling settlements. [1] Approximately 12 nations, all signatory to the Antarctic Treaty , send personnel to perform seasonal (summer) or year-round research on the continent and in its surrounding oceans.
Lists of mammals by region cover mammals found in different parts of the world. They are organized by continent, region, and country, and in some places by sub-national region. Most are full species lists, while those for Australia and the Caribbean have links to more specific species lists.
The most common lichens are Usnea and Bryoria species. Antarctica's two flowering plant species, the Antarctic hair grass (Deschampsia antarctica) and Antarctic pearlwort (Colobanthus quitensis) are found on the northern and western parts of the Antarctic Peninsula, including offshore islands, where the climate is relatively mild.
Today, the species is kept at just a few zoos and public aquariums in North America and Asia. Emperor penguins were first successfully bred at SeaWorld San Diego; more than 20 birds have hatched there since 1980. [94] [95] Considered a flagship species, 55 individuals were counted in captivity in North American zoos and aquaria in 1999. [96]
