No species occurs everywhere. Indeed, the majority are absent from most places, and where they do occur they are usually quite rare. Gaston discusses the structure of these distributions - the structure of the geographic ranges of species.
Gaston is particularly concerned with the factors that determine the limits to a species' geographic range, how the sizes of those ranges vary, and patterns in that variation. Also considered are the distribution of individuals amongst those sites where a species does occur and what determines that distribution, and some of the practical implications of...

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 maintain it.

• Timely overview of the serious attempts made to quantify and describe biodiversity in a scientific way
• Acts as an easy entry point into the primary literature
• Provides real-world examples of key issues, including illustrations of major temporal and spatial patterns in biodiversity
• Designed...

Population and community biology have been based largely on studies of abundant and widespread species. Most species are neither. This study draws together information from different disciplines on rarity. It draws general principles, focusing on the definition and measurement of rarity, its spatial and temporal dynamics, and its causes and interactions with conservation. Rare species are of particular concern to conservation because they tend to have a greater probability of extinction. This book should be of interest to conservation biologists, ecologists, environmental scientists and...

Issues of scale have become increasingly important to ecologists. This book addresses the structure of regional (large-scale) ecological assemblages or communities, and the influence this has at a local (small-scale) level. This macroecological perspective is essential for the broader study of ecology because the structure and function of local communities cannot be properly understood without reference to the region in which they are situated.

The book reviews and synthesizes the issues of current importance in macroecology, providing a balanced summary of the field that will be...

To say you are writing about rarity is to invite two kinds of response. Either one provokes a discussion of what rarity is, or some comment on the complex ity of the subject. The objective of this book is to explore the nature of rarity, its complexity if you like, from one particular perspective on what rarity is. Primarily, it is an opportunity to review, to synthesize, and to question. The book is an attempt to draw together a vast body of literature, to extract from it some general principles, and to raise question marks over areas the founda tions of which appear to be either absent or...
