Diet of Arctic Foxes (Alopex lagopus) in Greenland
The gastrointestinal tracts of 254 arctic foxes (Alopex lagopus) trapped or shot in Greenland, mainly during winter, were examined for the presence of food items. The occurrence of different food categories in the gastrointestinal tracts differed significantly between the geographical areas. Overall...
