Determinants of parasite distribution in Arctic charr populations: catchment structure versus dispersal potential
Abstract Parasite distribution patterns in lotic catchments are driven by the combined influences of unidirectional water flow and the mobility of the most mobile host. However, the importance of such drivers in catchments dominated by lentic habitats are poorly understood. We examined parasite popu...

Abstract Parasite distribution patterns in lotic catchments are driven by the combined influences of unidirectional water flow and the mobility of the most mobile host. However, the importance of such drivers in catchments dominated by lentic habitats are poorly understood.

Our results demonstrated that the abundance of most parasite taxa increased from the upper to lower catchment.
