1.关于改变一个局部物种的遗传变异的进化过程如何影响与其他物种的互动，影响群落和生态系统的结构或功能，以及随着时间的推移影响相互作用的物种之间的进化反馈的信息相对较少。由于进化可以在生态时间尺度上发生，因此重要的是要了解气候变化等重大选择性事件如何通过改变种内遗传变异来影响相互作用的物种群落和生态系统过程。将遗传变异和进化与群落变化和反馈联系起来的证据来自几种不同的方法，这些方法的结果还没有被综合到一个概念框架中，它们的共性可能也没有得到充分的理解。这篇综述综合了几种不同的关于进化如何影响群落和生态系统的实验方法，重点放在五个主要问题上：(1)群落和生态系统的遗传基础；(2)种群间遗传分化的群落和生态系统后果；(3)局部适应和共同进化的作用；(4)跨代反馈和生态环境动态的影响；(5)群落和生态系统遗传学和多水平选择的整合。进化可以改变种内遗传变异，从而影响间接遗传效应和反馈。未来的研究应该调查当进化导致反馈强度改变时，社区和生态系统是如何受到影响的。
P>1. There is relatively little information on how evolutionary processes that alter genetic variation in a focal species may affect interactions with other species, impact the structure or function of the community and ecosystem, and affect evolutionary feedbacks among interacting species through time.2. Because evolution can occur at ecological time-scales, it is important to understand how major selective events, such as climatic changes, can impact the community of interacting species and ecosystem processes by changing intraspecific genetic variation.3. The evidence linking genetic variation and evolution to community change and feedbacks has arisen from several different approaches whose results have not been synthesized into one conceptual framework, and whose commonalities may not be fully understood.4. This review synthesizes several different experimental approaches on how evolution may impact communities and ecosystems and focuses on five main issues: (i) the genetic basis to communities and ecosystems; (ii) the community and ecosystem consequences of among-population genetic differentiation; (iii) the role of local adaptation and co-evolution; (iv) the effects of trans-generational feedbacks and the eco-evo dynamic and; (v) the integration of community and ecosystem genetics and multi-level selection.5. Evolution can alter intraspecific genetic variation to affect indirect genetic effects and feedbacks. Future studies should investigate how communities and ecosystems are affected when evolution causes the strength of feedbacks to change.
