In an era of environmental change, the need to understand the factors that shape the distribution and abundance of organisms on our planet is of paramount importance. At a local scale, community composition can be influenced by both the characteristics of the local habitat, as well as by biological processes such as competition and predation. At the regional scale, rates of species dispersal and the composition of the regional species pool can determine which species are available to colonize local habitats. Incorporating information on the role of regional factors is important for evaluating how communities might respond to environmental change, as dispersal rates can influence the speed at which a species range shifts, as well as the rate at which species can evolve in response to changes in their environment (through the intake of new alleles to a population).

在一个环境变化的时代，了解影响地球上生物分布和丰度的因素至关重要。在局部范围内，群落的组成既受当地生境特点的影响，也受竞争和捕食等生物过程的影响。在区域一级，物种扩散的速度和区域物种库的组成可以决定哪些物种可以在当地生境定居。阐明区域因素作用的信息对于评估社区如何应对环境变化很重要，因为扩散率可以影响物种范围转移的速度，以及物种应对环境变化的进化速度（通过种群吸收新的等位基因）。
