Title
Diversity, propagation and evolution of mutualistic species’ community: a mathematical perspective.
Abstract
Mutualisms—ecological interactions between two or more species in which all partners benefit—are ubiquitous. For instance, most species in northern hardwood forests and grasslands rely on arbuscular mycorrhizal (AM) fungi for survival and persistence through reciprocal resource exchanges. Conversely, AM fungi depend on the colonization of plant roots for their own growth and survival. In this symbiosis, the symbionts—the AM fungi—inhabit a dynamic and changing environment—the host plant—whose properties are directly modified by the fungi themselves, creating feedback loops that shape the behaviour and dynamics of both partners.
These reciprocal feedbacks between species and environment raise fundamental questions that I will address in this talk: How do mutualisms emerge and evolve, and under what conditions can mutualistic interactions persist? Is mutualism maintained during range expansion? Finally, how resilient are mutualistic systems to invasion by other species?
Biography
Jimmy Garnier is a mathematician working at the interface of ecology and evolution. After completing a PhD on the mathematical analysis of population dynamics models based on partial differential equations, followed by a postdoctoral fellowship in Mark Lewis’s laboratory at the University of Alberta, he has been a junior researcher at the French National Centre for Scientific Research (CNRS) since 2013.
His research bridges applied mathematics and theoretical ecology. He develops and analyzes mathematical models based on partial differential equations, integro-differential equations, and stochastic processes to gain insight into ecological and evolutionary dynamics. The main objective of his research is to understand how species adapt to changing environments.
One-on-one meeting
Jimmy Garnier will be visiting UBC Okanagan from February 3 to 6. If you would like a one-on-one meeting, please contact tanja.voegel@ubc.ca.
