Warder C. Allee brought attention to the possibility of a positive relationship between
aspects of fitness and population size 50 years ago. Until recently, however, this concept …

From the snub-nosed monkeys of China to the mountain gorillas of central Africa, our closest
nonhuman relatives are in critical danger worldwide. A recent report, for example, warns that …

Allee effects are (broadly) defined as a decline in individual fitness at low population size or
density. They can result in critical population thresholds below which populations crash to …

This topical and exciting textbook describes fisheries exploitation, biology, conservation and
management, and reflects many recent and important changes in fisheries science. These …

This concise introductory text provides a complete overview of biodiversity-what it is, how it
arose, its distribution, why it is important, human impact upon it, and what should be done to …

To understand modern principles of sustainable management and the conservation of
wildlife species requires intimate knowledge about demography, animal behavior, and …

We examine a database of over 700 spawner-recruitment series to search for parameters
that are constant, or nearly so, at the level of a species or above. We find that the number of …

Textbooks on the principles of conservation biology abound. Yet, how does one put this
theoretical knowledge into practice? The aim of The Conservation Handbook is to provide …

Anthropogenic factors constitute the primary deterministic causes of species declines,
endangerment and extinction: land development, overexploitation, species translocations …

To select appropriate recovery strategies for endangered populations, we must understand
the dynamics of small populations and distinguish between the possible causes that drive …
