There is increasing interest in understanding the processes that maintain phenotypic variation in groups, populations, or communities. Recent studies have investigated how the phenotypic composition of groups or aggregations (e.g., its average phenotype or phenotypic variance) affects ecological and social processes, and how multi-level selection can drive phenotypic covariance among interacting individuals. However, we argue that these questions are rarely studied together. We present a unified framework to address this gap, and discuss how group phenotypic composition (GPC) can impact on processes ranging from individual fitness to population demography. By emphasising the breadth of topics affected, we hope to motivate more integrated empirical studies of the ecological and evolutionary implications of GPC.
人们对理解维持群体、种群或群落中表型变异的过程越来越感兴趣。最近的研究调查了群体或聚集体的表型组成（例如其平均表型或表型方差）如何影响生态和社会过程，以及多层次选择如何驱动相互作用个体之间的表型协方差。然而，我们认为这些问题很少被一起研究。我们提出了一个统一的框架来填补这一空白，并讨论群体表型组成（GPC）如何影响从个体适合度到种群统计学等一系列过程。通过强调受影响主题的广度，我们希望激发更多关于GPC生态和进化意义的综合实证研究。
