The Sixth International Conference on Mediterranean Climate ecosystems was held at Maleme (Crete), Greece, from September 23 to September 27, 1991. This conference had as its theme 'Plant-Animal Interactions in Mediterranean-type Ecosystems'. Most of the papers presented to that meeting have already been published (see Thanos, C.A. ed., 1992, Proceedings of the VI International Conference on Mediterranean Climate Ecosystems, Athens, 389 pp.). These 57 papers were all necessarily short. But the theme of plant-animal interactions was considered by the Organizing Committee to be so important to a fundamental understanding of the ecology of Mediterranean-climate ecosystems and to an enhanced management ·of those systems that various international research scientists were invited to prepare longer contributions on major aspects of the overall theme. The Book that follows represents the result of those invitations. All five regions of Mediterranean climate are represented - Chile, California, southern Australia and the Cape Province of South Africa, as well as the Mediterranean Basin itself.
