Minisymposium Talk Population Dynamics, Ecology & Evolution Population Dynamics in Disturbed Landscapes

Speaker

Daniel Franco (Universidad Nacional de Educación a Distancia, Spain)

Description

Habitat fragmentation, driven by human activities, poses a major threat to biodiversity by isolating populations and disrupting ecological processes. Metapopulation models are essential for understanding these dynamics, but they often assume temporally homogeneous environments. This assumption overlooks the reality that abiotic and biotic factors, such as temperature or resource availability, fluctuate over time, altering growth and competition. In this talk, we will show that such temporal heterogeneity can alter the impact of dispersal on total population size, leading to new response patterns not observed in constant environments using a discrete-time two-patch model.
