The process of colonization in Antarctic terrestrial and freshwater ecosystems
Abstract: Severe and depauperate ecosystems provide excellent sites for studies of colonization. Energy and resource limitations act as effective filters to establish-ment and development of conlmunities. Propagule availability must be considered from both local and long-distance sources with conseq...
