相邻树种的功能多样性对树液流动密度和重点树种的径向生长有促进作用，但常绿阔叶树种和落叶阔叶树种的作用方式不同

树木的功能是由邻近物种通过种间相互作用和当地环境形成的。邻近树种的功能性状组成可以为了解邻近树种对焦点树种资源策略的影响提供机理上的启示。在本研究中，我们在大规模森林生物多样性操纵实验（BEF-China）中对12个物种48棵树的树液流动密度（SFD）和径向生长进行了自动高频测量，以研究邻近物种的功能性状组成对焦点树树液流动和径向生长的影响及其内在机制。我们发现SFD与生长之间存在正相关，反映了树液流动在树木生长中的重要支持作用。当考虑到所有树种时，邻近树种的高功能多样性（FD）会抑制SFD，但会促进生长，从而提高水分利用效率。邻近树木的习得性对生长有积极影响，表明种间具有促进作用。此外，邻近 FD 有利于常绿乔木的生长。然而，在落叶焦点树中，邻近FD降低了SFD，但对生长没有显著影响。我们的研究结果表明，考虑邻近群落的功能性状组成将有助于有效的植树造林和森林管理。在期刊博客上免费阅读本文的通俗摘要。

期刊介绍： Functional Ecology publishes high-impact papers that enable a mechanistic understanding of ecological pattern and process from the organismic to the ecosystem scale. Because of the multifaceted nature of this challenge, papers can be based on a wide range of approaches. Thus, manuscripts may vary from physiological, genetics, life-history, and behavioural perspectives for organismal studies to community and biogeochemical studies when the goal is to understand ecosystem and larger scale ecological phenomena. We believe that the diverse nature of our journal is a strength, not a weakness, and we are open-minded about the variety of data, research approaches and types of studies that we publish. Certain key areas will continue to be emphasized: studies that integrate genomics with ecology, studies that examine how key aspects of physiology (e.g., stress) impact the ecology of animals and plants, or vice versa, and how evolution shapes interactions among function and ecological traits. Ecology has increasingly moved towards the realization that organismal traits and activities are vital for understanding community dynamics and ecosystem processes, particularly in response to the rapid global changes occurring in earth’s environment, and Functional Ecology aims to publish such integrative papers.
