Between geometry and biology: How and why does the number of species depend on area
Date:11/10/2011

increase with area, and under which conditions it takes place.

Within these constraints, there is a room for biological effects such as the spatial aggregation of individuals within each species to affect the relationship. The species-area relationship is thus driven by the interplay of purely geometrical constraints and biological effects concerning patterns of distribution of individual species. Consequently, even though the shape of the species-area relationship shows pronounced regularities, its variation can reflect ecological differences between groups.
