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. Microbiome on the High Antarctic Plateau

Abiotic stress is the negative impact of non-living factors on the living organisms in a specific environment. [1] The non-living variable must influence the environment beyond its normal range of variation to adversely affect the population performance or individual physiology of the organism in a significant way.

The oceans themselves are a more stable environment for life, both in the water column and on the seabed. There is relatively little diversity in Antarctica compared to much of the rest of the world. Terrestrial life is concentrated in areas near the coast. Flying birds nest on the milder shores of the Peninsula and the subantarctic islands.
It is a simple relationship between a host (the forest), an agent (the beetle) and the environment (the weather and temperature). [89] However, as climate change causes mountain areas to become warmer and drier, pine beetles have more power to infest and destroy the forest ecosystems, such as the whitebark pine forests of the Rocky Mountains. [89]
Habitat can be defined as the natural environment of an organism, the type of place in which it is natural for it to live and grow. [ 4 ] [ 5 ] It is similar in meaning to a biotope ; an area of uniform environmental conditions associated with a particular community of plants and animals.
