Lemurs -

Résumé :
Lemurs: Ecology and Adaptation brings together information from recent research, and provides new insight into the study of lemur origins, and the ecology and adaptation of both extant and recently extinct lemurs. In addition, it addresses issues of primate behavioral ecology and how environment can play a major role in explaining species variation. Moreover, in a larger context, the information contained in this volume expands our knowledge of primate ecology and allows us further insight into mammalian adaptations to unusual and often harsh environmental conditions that arise from both natural and anthropogenic factors. The book is divided into two sections. The first section is a background to lemurs and their ecology and it includes chapters on origins of lemurs, history of ecological studies on lemurs in Madagascar, theories relating to the evolution of lemur traits, and ecology of the recently extinct (sub-fossil) lemurs. Section two is comprised of chapters focusing on the ecology and adaptations of many species of extant lemurs to the diverse habitats found on Madagascar, and in some cases, adaptations to extreme climatic variability and natural disasters.
