在早期植物演替过程中，群落的系统发育结构会因重要的环境过滤器和新兴物种相互作用而发生变化。我们追踪了流域土壤初级演替的前 7 年温带植物群落的发展，以探索初始物种组装的模式。我们发现邻近植物组合的系统发育组成存在明显的小规模差异，并且存在大规模系统发育均匀性的趋势。这种小规模的变化似乎是由土壤特性（特别是碳酸盐含量）介导的。因此，非生物环境条件可能会抵消甚至取代密切相关的物种之间种间竞争的影响，而这些物种通常被预测会表现出系统发育均匀性的模式。我们的结论是，系统发育群落组成的理论需要考虑环境因素小规模变异的影响。
During early plant succession, the phylogenetic structure of a community changes in response to important environmental filters and emerging species interactions. We traced the development of temperate-zone plant communities during the first 7 years of primary succession on catchment soils to explore patterns of initial species assembly. We found pronounced small-scale differences in the phylogenetic composition of neighbouring plant assemblages and a large-scale trend towards phylogenetic evenness. This small-scale variability appears to be mediated by soil properties, particularly carbonate content. Therefore, abiotic environmental conditions might counteract or even supersede the effects of interspecific competition among closely related species, which are usually predicted to exhibit patterns of phylogenetic evenness. We conclude that theories on phylogenetic community composition need to incorporate effects of small-scale variability of environmental factors.
