Helminths of grizzly bears ( Ursus arctos ) and American black bears ( Ursus americanus ) in Alberta and British Columbia, Canada
Between May 2011 and June 2013, we collected the carcasses and gastrointestinal tracts of 40 American black bears (Ursus americanus Pallas, 1780) and 13 grizzly bears (Ursus arctos L., 1758) from populations of Alberta and British Columbia, Canada. Specimens were examined for helminths, which were i...
