Cyrille Violle

个人简介：

Cyrille Violle(PhD, 2007, Univ. Montpellier) is a CNRS senior researcher in the Center for Functional and Evolutionary Ecology (CEFE) at Montpellier, France. He is a functional ecologist who has gained extensive experience and international recognition in ecology, in particular functional ecology (his 2007 Oikos paper on functional traits has been cited 4,000 times) and community ecology (his 2012 Trends in Ecology and Evolution paper on intraspecific trait variability in community ecology has been cited 1,500 times). He has done both empirical and theoretical work. He has long had expressed strong interests in developing concepts, very often beyond his primary research area, as well as in coordinating field work, special issues, international workshops and networks. He has developed three main research axes: (i) investigating macroecological laws; (ii) investigating community assembly processes; (iii) investigating the ecological and evolutionary drivers of species traits, trade-offs and ecological strategies in both wild and cultivated species.

Exploring diversity through a functional lens: from dominant strategies to individual specialization

报告摘要：

I will give an overview of 30 years of research on functional diversity. I will demonstrate how the field of functional ecology has moved from a focus on dominant ecological strategies to a focus on individual specialization and rare phenotypes (so-called functional rarity). A mean field approach to biodiversity, by characterizing species with phenotypic averages, has been very successful to establish general patterns of biological diversification, in plants in particular. However, today, the maintenance of rare phenotypes in communities is puzzling for many ecologists. Intriguingly, taxonomic rarity (based on species frequency or abundance) is most often totally decoupled from functional rarity across taxa and ecosystems, which opens major theoretical and applied (conservation) avenues. I will also demonstrate that these rare phenotypes can have major impacts on ecosystem functioning, beyond well-known diversity effects. Altogether, I call for bridging functional ecology and evolutionary biology, which should help elucidating the long quest for mechanisms that regulate the diversification of life.

报告题目：

群落构建：从种内性状变异到动态生态位

报告摘要：

基于假设种内性状变异及其作用远小于种间差异，群落生态位理论致力于以种间生态位的不同，解释和预测物种共存和群落生物多样性的形成、维持和变化机理。近年来，随着随机过程和生态-演化动态在群落构建中的重要性被广泛认可，一些学者试图检验、更新和发展群落生态位理论。以报告者长期的方法摸索和在青藏高原高寒草地的实践验证，本讲座将：(1) 说明种内性状变异（而非物种多样性变化）驱动高寒草地群落功能结构时空变化；（2）论证群落水平种内变异是否有模式可循；（3）探讨群落种内变异形成中环境筛选、生物相互作用等生态环境因素的相对重要性。基于此，报告者试图放宽生态位理论的基本假设，以动态生态位（dynamic niche）概念重建群落构建的基本理论。
