Functional traits of species, which are responsible for demographic characteristics, environmental preferences, and competitive abilities, may have essential linkages with species abundance in a community, but we lack a general understanding of trait–abundance relationships in tree communities. This study investigated three questions: (a) is the relative abundance of tree species monotonically correlated with their functional traits; (b) are abundant species functionally similar or dissimilar to each other; and (c) do trait–abundance relationships change along temperature or successional gradients?

温度和演替梯度下树木群落的性状-丰度关系

物种的功能性状与人口特征，环境偏好和竞争能力有关，可能与社区中物种的丰富度有本质联系，但是我们对树木社区的性状-丰度关系缺乏普遍的了解。这项研究调查了三个问题：（a）树种的相对丰度与它们的功能性状单调相关；（b）在功能上彼此相似或不相似的丰富物种；（c）性状-丰度关系是否随温度或连续梯度变化？
