Temporal stability of polymorphic Arctic charr parasite communities reflects sustained divergent trophic niches
Polymorphic Arctic charr Salvelinus alpinus populations frequently display distinct differences in habitat use, diet, and parasite communities. Changes to the relative species densities and composition of the wider fish community have the potential to alter the habitat niche of sympatric Arctic char...
