Gorillas are one of our closest living relatives, the largest of all living primates, and teeter on the brink of extinction. These fascinating animals are the focus of this in-depth and comprehensive examination of gorilla biology. Gorilla Biology combines recent research in morphology, genetics and behavioral ecology to reveal the complexity and diversity of gorilla populations. The first section focuses on morphological and molecular variation and underscores the importance of understanding diverse biological patterns at all levels in testing evolutionary and adaptive hypotheses and elucidating subspecies and species diversification. Following are discussions of the ecological constraints that influence gorilla social organization and highlight their surprising flexibility. The book ends with discussions of the conservation status of gorillas and the many and increasing threats to their continued survival. Giving insight into the evolutionary biology of these unique primates, this book will be essential reading for primatologists, anthropologists and evolutionary biologists.
