种群间表型分布的空间异质性对于物种进化和生态系统功能至关重要。长期以来，人们一直认为扩散通过产生不适应的基因流来使结构化景观中的种群同质化，从而使表型的空间异质性传统上被认为是局部适应或可塑性的结果。然而，越来越多的证据表明，个体并不是在景观中随机分散，而是根据其表型和环境条件调整其分散决策。具体来说，个体可能会在景观中移动，寻找并定居在最适合其表型的环境条件中，从而最大限度地提高其适应度，这一假设称为栖息地匹配。尽管栖息地匹配和相关的非随机基因流可以产生空间表型异质性，但它们对集合种群和元群落功能的潜在影响仍然知之甚少。在这里，我们讨论了栖息地匹配的种内和种间驱动因素的证据，并强调了这一过程对集合种群和元群落功能的潜在影响。我们得出的结论是，栖息地匹配可能会深刻影响元系统的生态进化动态，并指出需要对其发生率及其对环境变化下物种和群落进化的影响进行进一步的实证和理论研究。
Spatial heterogeneity in the distribution of phenotypes among populations is of major importance for species evolution and ecosystem functioning. Dispersal has long been assumed to homogenise populations in structured landscapes by generating maladapted gene flows, making spatial heterogeneity of phenotypes traditionally considered resulting from local adaptation or plasticity. However, there is accumulating evidence that individuals, instead of dispersing randomly in the landscapes, adjust their dispersal decisions according to their phenotype and the environmental conditions. Specifically, individuals might move in the landscape to find and settle in the environmental conditions that best match their phenotype, therefore maximizing their fitness, a hypothesis named habitat matching. Although habitat matching and associated non-random gene flows can produce spatial phenotypic heterogeneity, their potential consequences for metapopulation and metacommunity functioning are still poorly understood. Here, we discuss evidence for intra and interspecific drivers of habitat matching, and highlight the potential consequences of this process for metapopulation and metacommunity functioning. We conclude that habitat matching might deeply affect the eco-evolutionary dynamics of meta-systems, pointing out the need for further empirical and theoretical research on its incidence and implications for species and communities evolution under environmental changes.
