DOWNLOAD EBOOKThis book explores the factors affecting the survival of small populations. As the human impact on Earth expands, populations of many wild species are being squeezed into smaller and smaller habitats. As a consequence, they face an increasing threat of extinction. The authors review these theoretical ideas, the existing data, and explore the question: how well do small and isolated populations actually perform?
