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PIRasmann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 Frontiers in Ecology and Evolution期刊的Review Editor。在NaturePNASEcology LettersJournal of EcologyNew PhytologistPlant PhysiologyAnnual 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.
