Exploring trophic niches and parasite communities of sympatric Arctic charr and brown trout populations of southern Norway
Catchment-scale variation between lake habitats has the potential to simultaneously influence the trophic niche and parasite community of fish hosts. In this study, we investigated the trophic niche and parasite community of sympatric Arctic charr and brown trout populations from two inter-connected...
