Humans are drastically changing the spatial configuration of habitats. The associated changes in habitat connectedness impose strong selection on dispersal, and dispersal related traits. Evolutionary responses do, however, strongly feedback on the metapopulation dynamics, by further constraining or improving connectivity and impacting local population and food web dynamics. Because these spatial eco-evolutionary interactions occur at contemporary time scales, unique evidence on its importance is especially emerging in the field of entomology as many insects have short generation times and a huge reproductive potential. We review the ecological feedbacks originating from the evolution of dispersal rate, dispersal syndromes and genetic diversity on metapopulation dynamics and range expansions. We thus close the eco-evolutionary loop for insect and arachnid spatial dynamics.
人类正在剧烈地改变栖息地的空间配置。这种生境连接性的变化对扩散和扩散相关特征施加了强烈的选择压力。然而，进化反应通过进一步限制或改善连通性并影响局部种群和食物网动态，强烈地反馈到了复合种群动态中。由于这些空间生态进化相互作用发生在当代的时间尺度上，因此在昆虫学领域中，特别出现了关于其重要性的独特证据，因为许多昆虫具有较短的世代时间和巨大的繁殖潜力。我们回顾了源于扩散率、扩散综合征和遗传多样性进化对复合种群动态和分布范围扩展的生态反馈。因此，我们为昆虫和蛛形纲动物的空间动态闭合了生态进化循环。
