| associations between body composition and helminths of lesser snow geese during winter and spring migration. | costs of parasitism are predicted to be higher with greater parasite intensities and higher inter-parasite competition (diversity). we tested whether greater helminth intensities and diversity were associated with poorer body composition (whole-body fat, protein, mineral and true body mass) in lesser snow geese, chen caerulescens caerulescens. as part of a larger study on nutritional ecology, 828 wintering or migrating geese were shot between january and may 1983 in 27 different date-locations ( ... | 2012 | 22713759 |
