Empirical and theoretical approaches to understanding diversity patterns across multiple spatial scales

摘要: Patterns of variation in species richness are some the oldest known ecological phenomena. Centuries research into their causes have revealed surprisingly few general insights, one which is that factors control depend on spatial scale. At large scales, processes such as dispersal, speciation and extinction though to be most important, while biological interactions can important at small scales. The abiotic environment affects all these processes. For example, high temperatures promote speciation, small-scale environmental heterogeneity slow competitive exclusion.
