The University of Chicago Press Food Webs
Although it was first published twenty years ago, Stuart Pimm's Food Webs remains the clearest introduction yet to the study of food webs, diagrams depicting which species interact - in other words, who eats whom. Reviewing various hypotheses in light of theoretical and empirical evidence, Pimm shows that even the most complex food webs follow certain patterns, and that those patterns are shaped by a limited number of biological processes - processes he provides mathematical tools for unraveling (and concrete examples of those tools' application). This edition adds a new foreword covering recent developments in the study of food webs and demonstrating their continuing importance to conservation biology, particularly attempts to predict which communities are most vulnerable to disturbance.

The University of Chicago Press The Balance of Nature? – Ecological Issues in the Conservation of Species and Communities
Ecologists, although they acknowledge the problems involved, generally conduct their research on too few species, in too small an area, over too short a period of time. In The Balance of Nature?, a work sure to stir controversy, the distinguished theoretical ecologist Stuart L. Pimm argues that ecology therefore fails in many ways to address the enormous ecological problems now facing our planet. Ecologists describing phenomena on larger scales often use terms like "stability," "balance of nature," and "fragility," and Pimm begins by considering the various specific meanings of these terms. He addresses five kinds of ecological stability--stability in the strict sense, resilience, variability, persistence, and resistance--and shows how they provide ways of comparing natural populations and communities as well as theories about them. Each type of stability depends on characteristics of the species studied and also on the structure of the food web in which the species is embedded and the physical features of the environment. The Balance of Nature? provides theoretical ecology with a rich array of questions--questions that also underpin pressing problems in practical conservation biology. Pimm calls for nothing less than new approaches to ecology and a new alliance between theoretical and empirical studies.
