Shifts in species' distribution and abundance in response to climate change have been well
documented, but the underpinning processes are still poorly understood. We present the …

From the red grouse to the Ethiopian bush-crow, bird populations around the world can
provide us with vital insights into the effects of climate change on species and ecosystems …

Background The migratory patterns of animals are changing in response to global
environmental change with many species forming resident populations in areas where they …

In most long‐distance migratory birds, juveniles migrate without their parents and so are
likely to lack detailed knowledge of where to go. This suggests the potential for stochasticity …

Aim Global declines in the populations of migratory species have been attributed largely to
climate change and anthropogenic habitat change. However, the relative contribution of …

A major question in ecology is how age-specific variation in demographic parameters
influences population dynamics. Based on long-term studies of growing populations of birds …

Climate is a major extrinsic factor affecting the population dynamics of many organisms. The
Broad‐Scale Climate Hypothesis (BSCH) was proposed by Elton to explain the large‐scale …

Aim Recent, rapid population declines in many Afro‐Palaearctic migratory bird species have
focussed attention on changing conditions within Africa. However, processes influencing …

Human‐induced changes in the climate and environment that occur at an unprecedented
speed are challenging the existence of migratory species. Faced with these new challenges …

Climate change affects both the mean and variability of climatic variables, but their relative
impact on the dynamics of populations is still largely unexplored. Based on a long‐term …
