Data from: Little impact of over-winter parasitism on a free-ranging ungulate in the high Arctic
1.Macroparasites have a central place in wildlife ecology because they have the potential to regulate host populations through effects on reproduction and/or survival. However, there remains a paucity of studies that have demonstrated the regulatory role of these parasites in free-ranging animals. 2...
