Opis

Early research on ant-plant interactions in Australia was largely confined to the economically important problem of ants harvesting surface-sown pasture seed (e. g. Campbell 1966). The report by Berg (1975) of widespread myrmecochory in Australia, and a burst of overseas research, stimulated research on a range of ant-plant interactions in Australia. This book summarizes such research and presents reeent and current work on seed harvesting, myrmecochory, ant-epiphytes, extrafloral nectaries, ant-plant-homopteran systems, and the influence of vegetation on ant faunas. I hope that it will encourage further work in these and related areas, and that the review and bibliography of ant-plant interactions in the rest ofthe world will serve as a useful source for those entering the field. The richness of Australia's flora and ant fauna render it a particularly interesting continent for the study of interactions between them. As immediately apparent from the list of contents, ant-seed interactions are particularly significant in Australia. This is not surprising for a relatively dry continent bearing a largely sc1erophyllous plant cover. Future research, however, especially in the tropical north, is like1y to reveal further types of interaction, perhaps corresponding to those characteristic of the tropics elsewhere, or perhaps distinctively Australian. Some of the chapters have been shortened and modified considerably from the original manuscripts, but the ideas and results presented are, of course, those of the individual authors.
