Behavioural responses of benthic and pelagic Arctic charr to substratum heterogeneity
Responses to environmental heterogeneity were studied in laboratory‐reared offspring of two morphs of Arctic charr Salvelinus alpinus from Loch Rannoch, Scotland, one occupying the pelagic zone and feeding predominantly on zooplankton and the other being benthic in habit and feeding mainly on macroi...
