系统发生群落生态学试图通过分析物种的系统发生结构来解释物种组合形成的过程，迄今为止主要侧重于地方规模的群落。另一方面，宏观生态学关注的是大地理尺度上的群落结构，但在很大程度上仍然是非系统发育的。分析大规模生物组合的系统发育结构为这两个研究方案提供了联系。在本文中，我问我们是否应该期待大规模的组合，以显示显着的系统发育结构，通过概述一些生态和宏观进化过程中可能发挥作用的组合形成。作为一个案例研究，我然后探讨非洲的陆地生态区内的食肉动物组合的系统发育结构。许多组合在这些尺度上确实是非随机的（集群或过度分散）。观察到的模式的系统发育结构的一种解释是，许多分支经历了快速的生物群填充辐射，其次是多样化放缓和竞争性排序的生态位空间变得饱和。
Phylogenetic community ecology seeks to explain the processes involved in the formation of species assemblages by analysing their phylogenetic structure, and to date has focused primarily on local-scale communities. Macroecology, on the other hand, is concerned with the structure of assemblages at large geographical scales, but has remained largely non-phylogenetic. Analysing the phylogenetic structure of large-scale assemblages provides a link between these two research programmes. In this paper, I ask whether we should expect large-scale assemblages to show significant phylogenetic structure, by outlining some of the ecological and macroevolutionary processes that may play a role in assemblage formation. As a case study, I then explore the phylogenetic structure of carnivore assemblages within the terrestrial ecoregions of Africa. Many assemblages at these scales are indeed phylogenetically non-random (either clustered or overdispersed). One interpretation of the observed patterns of phylogenetic structure is that many clades underwent rapid biome-filling radiations, followed by diversification slowdown and competitive sorting as niche space became saturated.
