嘉宾简介：Sergio Rasmann博士现任瑞士纳沙泰尔大学生物系助理教授兼功能生态实验室PI，Rasmann博士毕业于纳沙泰尔大学，博士毕业后先后以博士后、助理研究员和助理教授身份在康奈尔大学Agrawal实验室、瑞士洛桑大学和加州大学欧文分校开展工作或任教。Rasmann博士的研究方向主要涉及植物化学通讯介导的地上/地下部三级营养级间的相互作用；植物化学防御的进化与生态功能；生态因子对植物适应性和驯化的作用。Rasmann首次证实了根系挥发性气体介导的生态防虫效应，是当今国际上非常活跃年轻的生态学学者之一，现担任Fucntional Ecology副主编、Frontiers in Plant Sciences 和Frontiers in Ecology and Evolution期刊的Review Editor。在Nature、PNAS、Ecology Letters、Journal of Ecology、New Phytologist、Plant Physiology、Annual Review of Entomology等期刊上发表80余篇SCI论文，H指数30，近5年引用超过2800多次。

报告内容简介：Plants and their associate higher trophic levels organisms continuously exchange positive and negative information-rich signals in order to survive. Plants cannot escape herbivore attack, and have thus to defend via the production of so-called secondary metabolites. Such metabolites can reduce plant digestibility, poison the herbivore, or signal predators the presence of herbivores. I will here discuss how the chemically mediated plant-herbivore-predator communication is strongly influenced by the context dependency associate with each system. Particularly I will focus on how ecological factors drive genotypic variation of these interactions, and I will expand on how ecological gradients are used to address the questions related to context-dependency.
