▪ Abstract The latitudinal gradient of decreasing richness from tropical to extratropical areas
is ecology's longest recognized pattern. Nonetheless, notable exceptions to the general …

Despite two centuries of exploration, our understanding of factors determining the
distribution of life on Earth is in many ways still in its infancy. Much of the disagreement …

Understanding the causes of spatial variation in species richness is a major research focus
of biogeography and macroecology. Gridded environmental data and species richness …

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 …

Aim We conducted the most extensive quantitative analysis yet undertaken of the form taken
by the island species–area relationship (ISAR), among 20 models, to determine:(1) the best …

Most studies examining continental-to-global patterns of species richness rely on the
overlaying of extent-of-occurrence range maps. Because a species does not occur at all …

This pioneering graduate textbook provides readers with the concepts and practical tools
required to understand the maximum entropy principle, and apply it to an understanding of …

Species–area relationships (SAR) are fundamental in the understanding of biodiversity
patterns and of critical importance for predicting species extinction risk worldwide. Despite …

While horizontal gradients of biodiversity have been examined extensively in the past,
vertical diversity gradients (elevation, water depth) are attracting increasing attention. We …

The appropriateness of species richness as an ecological indicator or decision variable for
setting conservation and management priorities depends on many assumptions. Most …
