The continent of Antarctica itself has been too cold and dry to support any other vascular plants for millions of years. The scanty vegetation of Antarctica is a result of the chilling temperature, lack of sunlight, little rainfall, relatively poor soil quality , and a lack of moisture due to the inability of the plants to absorb water in the ...
In physical geography, tundra (/ ˈ t ʌ n d r ə, ˈ t ʊ n-/) is a type of biome where tree growth is hindered by frigid temperatures and short growing seasons. There are three regions and associated types of tundra: Arctic , [ 2 ] Alpine , [ 2 ] and Antarctic .

These islands have a somewhat milder climate than Antarctica proper, and support a greater diversity of tundra plants, although they are all too windy and cold to support trees. Antarctic krill is the keystone species of the ecosystem of the Southern Ocean , and is an important food organism for whales , seals , leopard seals , fur seals ...
Antarctica has around 400 lichen species, plants and fungi living symbiotically. [3] They are highly adapted, and can be divided into three main types; crustose lichens, forming thin crusts on the surface, foliose lichens, forming leaf-like lobes, and fruticose lichens , which grow like shrubs.
This species is one of only two flowering plants native to Antarctica, the other one being Antarctic pearlwort (Colobanthus quitensis). Throughout its history, Antarctica has seen a wide variety of plant life. In the Cretaceous, it was dominated by a fern-conifer ecosystem, which changed into a temperate rainforest by the end of that period.
Category:Flora of Antarctica — (the only area within the WGSRPD region of "Antarctic Continent") Native taxa of the lowest rank are included if they occur widely in the botanical continent, otherwise they should be included in the flora of one or more of the constituent regions. Higher taxa are included only if endemic
This is a list of terrestrial ecoregions as compiled by the World Wildlife Fund (WWF). The WWF identifies terrestrial , freshwater , and marine ecoregions . The terrestrial scheme divides the Earth's land surface into 8 biogeographic realms , containing 867 smaller ecoregions.
