The study found that along elevational gradients, phylogenetic and functional traits show inconsistent changes closely related to the abiotic environment. The community assembly of woody plants is significantly affected by both deterministic processes and the stochastic hypothesis, with the relationship between phylogenetic and functional traits changing according to different rules. These results enhance our understanding of forest community assembly mechanisms.
Explaining community assembly mechanisms along elevational gradients dominated by deterministic processes or stochastic processes is a pressing challenge. Many studies suggest that phylogenetic and functional diversity are significant indicators of the process. In this study, we analyzed the structure and beta diversity of phylogenetic and functional traits along an elevational gradient and discussed the effects of environmental and spatial factors. We found that the phylogenetic and functional traits showed inconsistent changes, and their variations were closely related to the abiotic environment. The results suggested that the community assembly of woody plants was obviously affected by the combined effect of deterministic processes and the stochastic hypothesis (primarily by the latter). Phylogenetic and functional traits had a certain relationship but changed according to different rules. These results enhance our understanding of the assembly mechanism of forest communities by considering both phylogenetic and functional traits.
