Abstract

The ecology of plant species relies on the synchronous functioning of leaves and roots, but few studies have simultaneously examined the community trait dispersion patterns (CTD) of both organs. We measured 16 analogous leaf and root traits on 44 co-occurring woody species in a subtropical forest in southern China, examining whether leaf and root traits were coordinated, organized into parallel trait axes, exhibited similar CTD, and displayed consistent responses in CTD and community-weighted means of (CWM) traits over environmental gradients. While the first axes of leaf and root trait variation similarly exhibited a fast – slow continuum, leaf traits covered a secondary ‘carbon economics’ axis, contrasting to root traits depicting a collaboration axis reflecting species’ mycorrhizal dependency. Analogous leaf and root chemical traits were generally coordinated but less so for morphological traits. At the community level, changes in the CWM of the first axes were generally consistent among organs with more conservative traits found as increasing elevation but not for the second axis. While root traits became thinner and more conservative as soil phosphorus decreased, leaf traits rarely varied. When different trait axes were combined, leaf traits were overdispersed but tended to converge with increased elevation and soil potassium and phosphorus levels, whereas root traits were clustered but tended to diverge along the same gradients. Our study highlights fine filtering of different suites of traits above- and below-ground, which in turn might reduce overall niche overlap among species and promote coexistence with diverse functional designs.
在亚热带森林中,叶片和根的性状部分协调,但它们显示出截然不同的基于多性状的群落性状分散模式
植物物种的生态依赖于叶和根的同步功能,但很少有研究同时考察这两个器官的群落性状离散模式(CTD)。我们测量了中国南方亚热带森林中44种共生木本植物的16个类似叶片和根的性状,考察了叶片和根的性状是否协调,是否组成平行的性状轴,是否表现出相似的群落性状扩散模式(CTD),以及在环境梯度上CTD和群落加权平均性状(CWM)是否表现出一致的响应。虽然叶片和根系性状变异的第一轴同样表现出快-慢的连续性,但叶片性状覆盖了次要的 "碳经济学 "轴,而根系性状则是反映物种菌根依赖性的协作轴。类似的叶片和根系化学性状通常是协调的,但形态性状则不太协调。在群落水平上,随着海拔的升高,第一条轴的化学成分变化在各器官之间基本一致,且性状更为保守,但第二条轴则不然。根的性状随着土壤磷的减少而变得更细、更保守,而叶的性状却很少变化。当把不同的性状轴结合在一起时,叶片性状过于分散,但随着海拔高度和土壤钾、磷水平的增加,叶片性状趋于一致,而根系性状则集中在一起,但沿着相同的梯度趋于分化。我们的研究强调了对地上和地下不同性状的精细过滤,这反过来又可能减少物种间的总体生态位重叠,促进具有不同功能设计的物种共存。

期刊介绍: Journal of Plant Ecology (JPE) serves as an important medium for ecologists to present research findings and discuss challenging issues in the broad field of plants and their interactions with biotic and abiotic environment. The JPE will cover all aspects of plant ecology, including plant ecophysiology, population ecology, community ecology, ecosystem ecology and landscape ecology as well as conservation ecology, evolutionary ecology, and theoretical ecology.
