Winter activity patterns in an invading Mediterranean population of American mink (Neovison vison)

摘要: Patterns of daily activity and the factors affecting it were studied in an invading Mediterranean population American mink, Neovison vison, radiotracked northeast Spain during post breeding season (winter - half year). We distinguished between local activity, defined as active behaviour without spatial displacement, locomotion while foraging or travelling, inactivity. effect sex, age, daylight (nocturnal diurnal), month, river flow average rainfall on eight males three females. Male mink presented more than females subadult had adult mink. Average per day a negative locomotion, no either total activity. Studied spent most their time inactive in-den. These results are accordance with patterns shown by other native invasive populations.
