Successional patterns of terrestrial wildlife following deglaciation
Abstract Disturbance is a key driver of community assembly and patterns of diversity. Whereas successional changes in vegetation have been well‐studied, postdisturbance successional patterns of wildlife communities remain poorly understood. Here, we investigated the roles of site age and habitat in...

Abstract Disturbance is a key driver of community assembly and patterns of diversity. Whereas successional changes in vegetation have been well‐studied, postdisturbance successional patterns of wildlife communities remain poorly understood.
