Temporal dynamics of helminth infections in eastern grey kangaroos (Macropus giganteus) in Victoria

Abstract

Parasite infection is increasingly recognised as a factor shaping the population dynamics, life history and behaviour of hosts. However, before the impacts of parasites on wildlife hosts can be investigated, seasonal patterns in host exposure to parasitic agents must be determined. We examined infection patterns at three sites in Victoria, and combined field experiments and observations to construct a generalised life cycle of the helminth community in eastern grey kangaroos (Macropus giganteus). Kangaroo populations in Victoria had very similar helminth communities, with 20-25 species detected at each site. Despite examining relatively few hosts in this study, at least 87% of all gastrointe..
