Natural infection by intestinal cestodes: variability and effect on growth in Greater Snow Goose goslings ( Chen caerulescens atlantica )
We determined the species of intestinal helminths in Greater Snow Goose (Chen caerulescens atlantica) goslings and examined annual variability in infection levels over a 5-year period on Bylot Island, Nunavut. The intestines of 112 wild goslings collected when near fledging were examined. We also ev...
