Wintering French mallard and teal are heavier and in better body condition than 30 years ago : effects of a changing environment?
Animal populations are exposed to large-scale anthropogenic impact from e.g. climate change, habitat alteration and supplemental stocking. All of these may affect body condition in wintering dabbling ducks, which in turn may affect an individual's survival and reproductive success. The aim of t...
