Spatial gradients in country‐level population trends of European birds
Abstract Aim Population trends reflect influence of environmental drivers acting upon species' population dynamics. As the strength of this influence may change predictably in space, we test multiple hypotheses about spatial gradients in the effects of environmental drivers on bird population t...
