Antarctica is one of the most physically and chemically extreme terrestrial environments to be inhabited by lifeforms. [1] The largest plants are mosses, and the largest animals that do not leave the continent are a few species of insects.
The abiotic factors that environmental gradients consist of can have a direct ramifications on organismal survival. Generally, organismal distribution is tied to those abiotic factors, but even an environmental gradient of one abiotic factor yields insight into how a species distribution might look.
They are sensitive to environmental changes due to the specificity of the symbiotic microbial communities within them. As a result, they function as indicators of environmental health. [58] The largest is the whitish or dull yellowish Anoxycalyx joubini, sometimes called the giant volcano sponge in reference to its shape. It can reach a height ...

It established property rights and gave special privileges to seven claimant states – including the UK. Focus later shifted from possible resource extraction to environmental protection, the CRAMPA was shelved and in 1998 the Protocol on Environmental Protection to the Antarctic Treaty (Madrid Protocol) [3] came into force. Therefore, the ...
An invasive species is a species not native to a particular location which can spread to a degree that causes damage to the environment, human economy or human health. [19] In 2008, Molnar et al. documented the pathways of hundreds of marine invasive species and found shipping was the dominant mechanism for the transfer of invasive species in ...
The continent of Antarctica is so cold that it has supported only 2 vascular plants for millions of years, and its flora presently consists of around 250 lichens, 100 mosses, 25–30 liverworts, and around 700 terrestrial and aquatic algal species, which live on the areas of exposed rock and soil around the shore of the continent.
Polar ecology is the relationship between plants and animals in a polar environment. Polar environments are in the Arctic and Antarctic regions. Arctic regions are in the Northern Hemisphere, and it contains land and the islands that surrounds it.
