Download or read book The Structure and Dynamics of Geographic Ranges written by Kevin J. Gaston and published by OUP Oxford. This book was released on 2003-05-01 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 all these. Both in a pure and applied context, ecologists need a broader perspective on their subject matter than has historically prevailed. This book provides one such perspective. A must have book for any researchers and graduate students studying macroecology, biogeography and conservation biology.
