PELAGIC BIOGEOGRAPHY AND TEMPERATURE

The influence of recent temperature changes on plankton biogeography a nd vertical distribution are compared with temperature variations and biogeographical distributions in the geological past. The combination of food supply and temperature is determinant for vertical and horizon tal distribution patterns. From studies of paleo-biogeography we have predicted patterns of changes that might take place as a result of pos sible future climate change. Special attention has been given to likel y changes in the Vertical distribution of deep-sea animals.
