Less resilient ecosystems are prone to losing species and function following disturbance. This species loss is not independent – losing some species can lead to losing others, making ecological networks essential to measure when evaluating ecosystem resilience. Until recently, ecological networks provided mostly local assessments of ecosystem resilience to species loss (i.e., network robustness). As regional metawebs of species interactions become available, they can be coupled with projections of species distributions to ‘spatialize’ ecological networks, quantify their robustness to environmental change, and provide large-scale assessments of ecosystem resilience. We exemplify this with a regional trophic metaweb and climate change.
