Density-dependent reproduction causes winter crashes in a common vole population
International audience Common voles in western France exhibit threeyearpopulation cycles with winter crashes after largeoutbreaks. During the winter of 2011–2012, we monitoredsurvival, reproduction, recruitment and population growthrate of common voles at different densities (from low tooutbreak den...
