In "Parasitism, " Claude Combes explores the fascinating adaptations parasites have developed through their intimate interactions with their hosts. He begins with the biology of parasites--their life cycles, habitats, and different types of associations with their hosts. Next he discusses genetic interactions between hosts and parasites, and he ends with a section on the community ecology of parasites and their role in the evolution of their hosts. Throughout the book Combes enlivens his discussion with a wealth of concrete examples of host-parasite interactions.
