环境过滤还是生物竞争对亚热带常绿阔叶次生林群落的影响更显著?
[目的]种内变异不仅是群落功能性状多样性的主要来源,具有与种间变异相似的生态效应,可以深刻地理解群落构建和生态系统功能的内在机制。[方法]本研究选取了浙江省亚热带常绿阔叶次生林 30块固定监测样地中 79个物种,3546个DBH≥10cm个体的 9种性状(比叶面积、叶干物质含量、木材密度、叶面积、叶绿素含量、叶片氮含量、叶片磷含量、叶片钾含量和氮磷比)数据和群落数据。利用性状梯度法将物种功能性状分解成alpha(群落内)和beta(群落间)组分,…查看全部>>
Intra-specific variation is the main source of functional trait diversity and has similar ecological effects as inter-specific variation.We studied 79 species and 3546 individuals from 30 fixed monitoring plots in subtropical evergreen broad-leaved secondary forests in Zhejiang Province,China.Using trait gradient analysis,we examined nine traits(specific leaf area,leaf dry matter content,wood density,leaf area,chlorophyll content,leaf nitrogen content,leaf p…查看全部>>
