Lewis SMITH 1 Summary. Terrestrial ecosystems throughout much of Antarctica are exhibiting local changes in their environment which are, either directly or indirectly, influencing biological processes. Central to these changes is the present climatic warming being experienced, especially in the more northerly regions, which is causing substantial recession of glaciers and ice fields and creating new surfaces on which biota may become established. Other temporal changes occur as a function of the natural process of colonisation, growth and ecosystem development but which may be strongly influenced by minor variations in climate or other components of the environment.

By comparison with most other terrestrial biomes worldwide, ecological processes in Antarctic ecosystems are generally considered to proceed slowly. Thus, despite the strong prevailing westerly wind circulation, immigration of organisms from more northerly continental landmasses is inhibited because of the physical barriers to dispersal, mainly because of the great distances to be traversed. When aerobiological input is successful and viable organisms or propagules are deposited on ice-free land, notably in coastal areas, colonisation proceeds slowly because most environmental conditions combine to create a situation which is unfavourable for rapid establishment.
