• Synthesis of orangutan biology from all existing study sites, adopting a novel comparative approach.
• Analysis and comparison of the latest data, developing a theoretical framework to explain demographic and behavioural variation.
• Emphasis of the crucial impact of human settlement on orangutans and the future prospects for the survival of natural populations.
• Contribution of top names in the field.

Readership: This accessible text is suitable for both graduate level students and professional researchers in the fields of primatology, behavioural ecology, biological anthropology and conservation biology.
