The effect of temporal variability on the stability of species interactions

Theoretical Ecology Seminar from the IITE (https://iite.info) by Violeta Calleja-Solanas (Doñana Biological Station, Spain). Recorded 18th Nov 2025. Abstract: Despite increasing evidence of temporal variation in species interactions as a response to environmental conditions, most theoretical frameworks remain rooted in static assumptions. Little is known about the feedbacks between demographic and ecological processes that structure the temporal dynamics of communities, but understanding these processes is fundamental to better predict the fate of ecological communities under continuous variation of external drivers. Here, I will present an ecological framework with temporal networks thanks to rich multi-annual datasets subjected to interannual changes in rainfall, obtaining signed directed and weighted interactions. Environmental anomalies produce contrasting effects on the temporal networks' structure, the opportunities to coexist, and the species' overall performance.
