Effects of plant traits and the relative abundance of common woody species on seedling herbivory in the Thousand Island Lake region
Online published: 2017-12-24
植食性动物取食植物(植食作用)一直是生物多样性和生态系统功能研究的热点问题。植食作用能够显著影响植物幼苗的生长, 从而决定种群更新动态。以往的研究较少讨论植物的不同性状对幼苗植食作用差异的重要性, 也较少将之与物种相对多度对植食作用的影响进行比较。该文以千岛湖地区的16种常见木本被子植物幼苗为研究对象, 调查植物的11种功能性状和相对多度, 并运用回归模型和方差分解方法, 研究植物功能性状和物种相对多度对幼苗叶片受昆虫植食损伤(虫食率)的相对重要性, 探讨虫食率对植物功能性状的依赖性以及物种相对多度对虫食率的影响。结果表明叶片功能性状(即叶片碳氮比、叶片厚度)和物种相对多度对虫食率有重要影响, 二者共解释了种间虫食率变异的54%。在这些性状中, 有更高的防御能力、更低的营养成分和更高相对多度的物种虫食率更低。我们建议在未来的植食作用研究中, 应考虑基于个体水平的功能性状和基于群落水平的相对多度。

Aims Plant-herbivore interaction is a hot topic in the study of biodiversity and ecosystem functions. Herbivores can negatively affect seedling growth and therefore can alter the dynamics of plant recruitment. However, previous studies do not fully reveal the relative importance of different plant functional traits on herbivory intensity and rarely link herbivory to the relative abundance of plant species.Methods Here, we measured 11 plant functional traits and the relative abundance of seedlings of 16 common woody species in the subtropical forests on 29 islands in Thousand Island Lake, East China. We then used multivariate regression and variance partitioning to test the contribution of functional traits and the relative abundance to interspecific differences of insect herbivory intensity.Important findings Our study found that both plant functional traits (e.g. carbon nitrogen ratio, leaf thickness) and the relative abundance of woody species played important roles in herbivory intensity, and they jointly contributed 54% of the variance of the interspecific differences. Among these factors, species with higher defensive ability, lower nutrient content and higher relative abundance had lower herbivory intensity. We suggest to consider both individual level traits (functional traits) and community level attributes (the relative abundance) in future herbivory studies.
