Lack of synchronized breeding success in a seabird community: extreme events, niche separation, and environmental variability
International audience Synchrony in ecological systems, the degree to which elements respond similarly over time or space, can inform our understanding of how ecosystems function and how they are responding to global change. While studies of ecological synchrony are often focused on within-species d...
