This volume comprises invited contributions on aspects of plant-animal interactions in Mediterranean-type ecosystems, which was the subject of the Sixth International Conference on Mediterranean Climate Ecosystems held in Crete, Greece, from September 23 - 27, 1991.

The present volume includes papers presented in the International Symposium on Adaptations to Terrestrial Environment, held in Halkidiki, Greece from September 26th to October 2nd, 1982, as well as some invited ones from well known scientists working in the same field.
