Habitat fragmentation and global climate change are the two major environmental threats to the persistence of species and ecosystems. The probability of a species surviving such changes is strongly dependent on its ability to track shifts in the environmental, either by moving between patches of habitat or by rapidly adapting to local condition. These 'solutions' to problems posed by environmental change depend on dispersal propensity, motivating our desire to better understand this important behavior. This book is a comprehensive overview of the new developments in the study of dispersal and the state-of-the-art research on the evolution of this trait. The causes, mechanisms, and consequences of dispersal at the individual, population, and species levels are considered. The promise of new techniques and models for studying dispersal, drawn from molecular biology and demography is explored. Perspectives on the study of dispersal are offered from evolution, conservation biology, and genetics. Throughout the book, theoretical approaches are combined with empirical data, and examples are included from as wide a range of species as possible.

Why are some species monogamous while others are polygamous? Why are males usually more ornamented than females? What makes one organism the hunter and another the hunted? Why do some creatures stick together in groups while others prefer to go it alone? Can we talk of animal culture? Behavioural Ecology provides a fascinating insight into the evolutionary and ecological processes that underpin animal behaviour. Opening with an overview of the evolutionary and methodological framework of behavioural ecology, the book goes on to explore behaviours in terms of the selective pressures involved in their design. It addresses natural selection, sexual selection, and gene selection, before closing with an investigation of the human impact on behavioural ecology. Featuring chapters written by university teachers, each with research expertise in their respective fields, Behavioural Ecology has been moulded by Danchin, Giraldeau, and Cezilly to give a uniform voice throughout: it is a text with all the qualities of a multi-author book, but without the potential drawbacks. Behavioural Ecology offers a fresh, contemporary account of a field re-invigorated by advances in the last decade, making it the ideal teaching and learning text.

The ability of species to migrate has interested ecologists for many years. Now that so many species and ecosystems face major environmental change, the ability of species to adapt to these changes by dispersing, migrating, or moving between different patches of habitat can be crucial to ensuring their survival. This book provides a timely and wide-ranging overview of the study of dispersal and incorporates much of the latest research. The causes, mechanisms, and consequences of dispersal at the individual, population, species and community levels are considered. The potential of new techniques and models for studying dispersal, drawn from molecular biology and demography, is also explored. Perspectives and insights are offered from the fields of evolution, conservation biology and genetics. Throughout the book, theoretical approaches are combined with empirical data, and care has been taken to include examples from as wide a range of species as possible.
