Journal of Applied Ecology doi:10.1111/j.1365-2664.2009.01696.x Wolf survival and population trend using non-invasive capture–recapture techniques in the Western Alps
1. Reliable estimates of population parameters are often necessary for conservation management but these are hard to obtain for elusive, rare and wide-ranging species such as wolves Canis lupus. This species has naturally recolonized parts of its former habitat in Western Europe; however, an accurat...
