Differentiation in leaf and branch traits of angiosperms and their relationships between species abundance in the Thousand Island Lake Region(千岛湖被子植物枝叶性状分化及其与种多度的关系)
种间生态位分化是物种共存的重要原因，了解种间生态位分化特征对于推测物种多样性维持机制具有重要意义.植物的种间功能性状分化在一定程度上能够反映其生态位分化，进而导致植物在群落内的适合度差异.据此，本研究针对千岛湖地区75种常见木本被子植物，分析了8个与水分输导、资源获取和利用策略相关的功能性状分化，及其与物种多度的关系.主成分分析表明，种间功能性状的分化主要发生在比叶面积、叶绿素含量以及叶气孔密度上.8个性状中有5个，即叶绿素含量、叶片厚度、叶面积、比叶面积和最大树高具有一定程度的系统发育保守性（即Blomberg's K的p<0.05）.功能性状间的相关性广泛存在，且在使用系统...
