The number of species found at a given point on the planet varies by orders of magnitude, yet large-scale gradients in biodiversity appear to follow some very general patterns. Little mechanistic theory has been formulated to explain the emergence of observed gradients of biodiversity both on land and in the oceans. Based on a comprehensive empiric

The question "Why are there so many species?" has puzzled ecologist for a long time. Initially, an academic question, it has gained practical interest by the recent awareness of global biodiversity loss. Species diversity in local ecosystems has always been discussed in relation to the problem of competi- tive exclusion and the apparent contradiction between the competitive exclu- sion principle and the overwhelming richness of species found in nature. Competition as a mechanism structuring ecological communities has never been uncontroversial. Not only its importance but even its existence...

The global loss of biodiversity has led to a renewed interest in the underlying mechanisms that explain spatial differences and temporal change of diversity. This book synthesises recent advances in our understanding of interactions that enhance or diminish coexistence among competing species. It features a spatial view of competition and coexistence. The chapters are logically grouped and stitched together by the central organizing principle of spatial distribution and mobility of competing species and their resources. The text also covers ecological modelling and experimental evidence in...
