Potential climate change impacts on Arctic char Salvelinus alpinus L. in Ireland
Abstract Climate change has been identified as a global threat to Arctic char Salvelinus alpinus L. populations. Bayesian statistical models were used to identify important physical and ecological factors explaining Arctic char presence and persistence in Irish lakes. Maximum lake depth and the pres...
