摘要1.生态学家越来越多地使用功能和系统发育的方法来量化随机的，非生物过滤和生物过滤过程的相对重要性，塑造物种共存的模式。在热带树木群落的功能和系统发育分析的一个剩余的挑战是成功地整合在一个单一的分析的空间和大小尺度和栖息地的树木群落的功能和系统发育结构。2.我们分析了在中国西南部的20公顷的热带森林动态图树组合的功能和系统发育结构。由于生物相互作用的影响可能会变得更加明显，随着队列年龄的增长，在当地尺度上，在资源丰富的环境中，我们在三个大小类，六个空间尺度和六个不同的栖息地类型进行分析，使用10种植物功能性状和分子遗传学中发现的>400个树木分类群。3.所有的性状，除了叶面积和茎特异性电阻，有显着的，虽然弱的系统发育信号。对于林冠物种，系统发育聚类在小型和中型的大小类转向系统发育过度分散在最大的大小类，这种变化的分散与大小被发现在每个栖息地类型，并在所有的空间尺度。在精细的空间尺度上，随着大小类的增加，功能分散从聚集到过度分散。然而，在更大的空间尺度组合功能聚类的所有大小类和栖息地。4.跨越空间和大小尺度和生境的系统发育和功能结构为物种共生的确定性模型而不是中性模型提供了强有力的支持。研究结果也支持了这一假设，即非生物决定论是更重要的，在较大的尺度，而生物决定论是更重要的栖息地内较小的尺度。
Summary 1. Increasingly, ecologists are using functional and phylogenetic approaches to quantify the relative importance of stochastic, abiotic filtering and biotic filtering processes shaping the pattern of species co-occurrence. A remaining challenge in functional and phylogenetic analyses of tropical tree communities is to successfully integrate the functional and phylogenetic structure of tree communities across spatial and size scales and habitats in a single analysis. 2. We analysed the functional and phylogenetic structure of tree assemblages in a 20-ha tropical forest dynamics plot in south-west China. Because the influence of biotic interactions may become more apparent as cohorts age, on local scales, and in resource-rich environments, we perform our analyses across three size classes, six spatial scales and six distinct habitat types, using 10 plant functional traits and a molecular phylogeny for the >400 tree taxa found in the plot. 3. All traits, except leaf area and stem-specific resistance, had significant, albeit weak phylogenetic signal. For canopy species, phylogenetic clustering in small and medium size classes turned to phylogenetic overdispersion in the largest size class and this change in dispersion with size was found in each habitat type and across all spatial scales. On fine spatial scales, functional dispersion changed from clustering to overdispersion with increasing size classes. However, on larger spatial scales assemblages were functionally clustered for all size classes and habitats. 4. Phylogenetic and functional structure across spatial and size scales and habitats gave strong support for a deterministic model of species co-occurrence rather than for a neutral model. The results also support the hypothesis that abiotic determinism is more important at larger scales, while biotic determinism is more important on smaller scales within habitats.
