Climate and spatio‐temporal variation in the population dynamics of a long distance migrant, the white stork
Summary A central question in ecology is to separate the relative contribution of density dependence and stochastic influences to annual fluctuations in population size. Here we estimate the deterministic and stochastic components of the dynamics of different European populations of white stork Cico...
