二、报告人介绍

谈家祺

【个人简介】Dr. Jiaqi Tan is an Assistant Professor in the Department of Biological Sciences at Louisiana State University. His research focuses on the ecological and evolutionary mechanisms that drive biodiversity and ecosystem functioning,with a particular emphasis on host-associated microbial communities. Combining laboratory experiments,field studies,and molecular approaches,his work explores how host-microbiome interactions respond to environmental change and contribute to the stability of ecosystems. Dr. Tan received his Ph.D. from the Georgia Institute of Technology.

【报告题目】Eco-evolutionary dynamics in experimental microbial communities

【报告摘要】Microorganisms actively shape host fitness and evolutionary outcomes. In this talk,I will examine how interactions with microbial partners—both antagonistic and beneficial—influence the predictability and consequences of host adaptation. I will first discuss experimental work showing that the timing of microbial interactions, such as early exposure to parasites, can introduce historical contingency into host diversification, thereby reducing its repeatability. I will then highlight how eco-evolutionary feedback within microbiomes—where microbial evolution reshapes community structure and functional outputs—can alter host fitness across generations. Together,these studies reveal the dynamic and reciprocal nature of host–microbiome evolution and underscore the importance of incorporating microbial processes into our understanding of host adaptation and diversification.

【个人简介】邓美凤，中国科学院植物研究所，副研究员，主要研究领域为陆地生态系统养分循环及对全球变化响应。共发表相关SCI论文20余篇，其中以第一作者发表的代表性论文包括Nature Ecology & Evolution，Science Advances, Global Change Biology, New Phytologist等国际期刊。主持国家自然科学基金青年基金、面上基金及国家重点研发计划项目子课题，并担任植物生态学报的青年编委。

【报告题目】植物养分获取策略与植物-土壤互作协同调控植物多样性和生态系统功能

【报告摘要】本报告聚焦植物-土壤反馈（PSF）与养分循环在生物多样性维持与生产力调控中的作用，基于亚热带森林和海拔梯度两个系统，探讨不同菌根类型在养分获取和植物-土壤互作中的功能差异，以及PSF 在短程高程变化中对植物分布与群落结构的影响。通过整合微生物过程与植物策略，揭示多样性与生态功能耦合的生态机制，为理解全球变化背景下生态系统的稳定性与恢复潜力提供理论支持。
