Animal populations in relation to their food resources

The Committee considered early on that there were two possibilities for this Symposium. The result of the second approach, given in this volume, is therefore a mixture of preliminary progress reports on new or current lines of work, general reviews, and detailed reviews of long-term research projects. Papers were also invited from agriculturalists, nutritionists and behaviourists since each can contribute towards a better understanding of the role of food in influencing populations.
