We applied a lottery model that considers landscape alteration and species dispersal abilities to analyse biodiversity resilience to increasing intensity wildfire disturbances in a pond macroinvertebrate metacommunity. We evaluated metacommunity recovery across gradients of wildfire size (area) and intensity (% of burned communities). Our simulated responses reported a highly resilient system. However, our model identified non-linear relationships between fire intensity and resilience. When fire intensity affects more than half of the landscape the network becomes fragmented, breaking stepping-stone recolonization dynamics for some dispersal groups and compromising recolonization from unburned or recolonized sites.
