“…However, in our study, the diversity pattern of the understory strata (shrubs and herbs) and the phylogenetic structure of the shrub layer were not significantly affected by climatic factors (Table 1). This finding contrasts with the work of Yuan et al (2013), who found the phylogenetic structure of shrub communities was affected by annual precipitation. The NRI and NTI measures of the phylogenetic structure showed a strong positive correlation with average dry season precipitation in the herb layer (Table 1; Figure 5), suggesting that climate variables are the key drivers of community assembly, at least in herbs.…”

Disentangling the distribution patterns of biodiversity along altitudinal gradients and their drivers has been a hot topic in ecological research. Different forest strata show multiple distribution patterns influenced by different community assembly mechanisms. Here, we measure the dominant ecological processes affecting three forest strata (tree, shrub, and herb layers) along altitudinal gradients. We sampled plants with different forest strata in 21 plots located from 2500 to 3700 m in Lasha Mountain, northwestern Yunnan. The taxonomic alpha diversity of the herb layer showed a monotonic decreasing trend with increasing altitude, while the shrub layer was characterized by a single peak, and the tree layer showed no significant change with increasing altitude. We observed a decreasing pattern of phylogenetic diversity with increasing altitude in the herb layer, whereas phylogenetic diversity did not change in the tree and shrub layers. The phylogenetic structure of these three layers showed the same pattern: phylogenetic clustering at low altitudes and overdispersion at middle and high altitudes. The diversity and phylogenetic structure of the herb layer were driven by climate (average dry season precipitation) and topographic (slope and aspect) factors, while shrub layer diversity was mainly influenced by tree layer richness. Overall, the phylogenetic structure pattern of the three forest strata changed from clustered to overdispersed with increasing altitude, indicating that environmental filtering was the main driver at low altitudes, while interspecific competition dominated at middle and high altitudes.

Phylogenetic structure of a community could effectively reflect underlying ecological processes of a community. Understanding phylogenetic structure of a community will help reveal the ecological processes associated with community dynamics. Data in a 1-ha plot were divided into quadrats at three spatial scales (10 m×10 m, 20 m×20 m, and 25 m×25 m) and three DBH sizes (1 cm ≤ DBH＜5 cm, 5 cm ≤ DBH＜10 cm, DBH ≥ 10 cm) to compare phylogenetic structures and to infer ecological processes of the community in a deciduous broad-leaved forest in the Baotianman National Nature Reserve. It was shown that NRI (net relatedness index) and NTI (net nearest taxa index) decreased with increasing spatial scales and DBH sizes. These results indicated that, phylogenetic structure of this community were overdispersed at different spatial scales and DBH sizes; and phylogenetic density dependence exerted higher effect on lager DBH classes than smaller ones. Our results suggested that phylogenetic density dependence is an important mechanism in regulating species diversity and shaping community structure of the deciduous broad-leaved for
