Both short- and long-term changes in ecosystems and community structures caused by natural and human factors were discussed to help understand the ecological processes taking place in a changing environment.

These distribution patterns all suggest a relatively slow interchange of plankton between the oceanic and shelf systems, which may cause relict distributions of species over the South Georgia shelf.

No seasonal trends could be identified. The limitation of the methods used are discussed, and spatial and temporal variability in Antarctic lakes is considered.
