Maxime Clenet - Integrating the temporal dimension of habitats into the study of metapopulations

Theoretical Ecology Seminar from the IITE (https://iite.info) by Maxime Clenet (Sherbrooke, Canada). Recorded 27th May 2025. Abstract: Habitat fragmentation, driven by natural events or human land use, is a major cause of biodiversity loss. Metapopulation models help explain how species facing local extinction can persist through colonization–extinction dynamics across a network of habitat patches. Much research, both empirical and theoretical, has focused on how habitat properties influence species survival. A key concept in this framework is metapopulation capacity, a metric derived from network structure that predicts species persistence. However, traditional models typically assume static landscapes, neglecting temporal changes in habitat connectivity. Here, using tools from Markov processes and multilayer networks, we extend the concept of metapopulation capacity to dynamic landscapes. By analyzing sequences of habitat snapshots, we can assess species persistence under changing conditions and inform strategies to mitigate fragmentation. This temporal extension provides a unified, theoretically grounded framework for understanding species survival in time-varying habitats.
