György Barabás
【个人简介】Dr. György Barabás (Linköping University, Sweden) is a community ecologist. He specializes in theoretical community ecology, focusing on species interactions and their influence on coexistence, ecosystem stability, robustness, and diversity. His research employs mathematical models and computational simulations to explore mechanisms of species coexistence and the dynamics of complex ecological networks. He enjoys collaborating with researchers across various disciplines and has experience integrating theoretical and empirical approaches in ecology.
【报告题目】Trait-based higher-order interactions and species coexistence
【报告摘要】A higher-order interaction between three species means that the presence of a third species modifies the interaction between the first two. A trait-based higher-order interaction is the same except between phenotypes instead of species. In this talk I discuss the effects of trait-based higher-order interactions on species coexistence in model communities. I use one-dimensional traits, such as root depth in the case of soil nutrient competition or height in the case of competition for light. On the surface, a confusing array of possibilities emerge which can be summed up as "adding higher-order interactions may have a positive, negative, or no effect on coexistence". However, I argue that by analyzing the relative widths of the pairwise and higher-order interaction kernels, we will understand which outcome to expect in any given scenario.

【报告题目】Complex responses of biodiversity to multiple environmental drivers
【报告摘要】主要介绍具有竞争-定殖权衡集合群落理论框架的构建，并利用该框架探讨多环境因素(如生境损失、生境破碎化、外来干扰以及资源生产力等)与生物多样性之间的关系，发现生物多样性对多环境因素产生了复杂的非线性波动响应，提出生物多样性‒生境破碎化存在单峰关系，从而为生物多样性保护提供了新的理论视角与决策依据。
