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.
