Abstract: Changes in abundance and the risk of extinction of the rock partridge Alectoris graeca saxatilis in the Dolomitic Alps were investigated using a density-dependent model that incorporated dispersal and environmental stochasticity. The study was based on spring and summer counts collected from sample areas in geographically distinct mountain groups. Extinction probability was investigated by simulating a discrete population and a metapopulation consisting of local populations connected by dispersal. Persistence…
