Seasonal food habits of marten in south-central Alaska
Studies of the diet of marten (Martes americana) and the abundance and habitat associations of small mammals were conducted in south-central Alaska for 2 years. Marten were found to eat primarily arvicolid (= microtine) rodents. Other important food items were sciurid rodents, fruits, and birds. Str...
