Behavioural plasticity and trophic niche shift: How wintering geese respond to habitat alteration
Abstract The accelerated rate of human‐induced environmental change poses a significant challenge for wildlife. The ability of wild animals to adapt to environmental changes has important consequences for their fitness, survival, and reproduction. Behavioural flexibility, an immediate adjustment of...
