This study is aimed at forecasting the changes in the suitability of brown trout habitat (Salmo trutta L.), caused by alterations in the stream temperature and the flow regime under climate change scenarios. The stream temperature and instantaneous flow in several streams in Central Spain were modelled from daily temperature and precipitation data. Logistic models were used for stream temperature modelling whereas M5? model trees were used to develop the precipitation-runoff models. These models were utilized to simulate the running flows under the climate change scenarios RCP4.5 and RCP8.5 (5thIPCC). The resulting forecasts suggested a different response of the stream temperature to the atmospheric warming in accordance with the geologic nature of basins. At the same time, significant decreases in summer flow and increases in the frequency of zero-flow events were predicted. In the future, significant declines in summer flow could exacerbate the negative impact on trout populations of increased water temperature by reducing both the suitable spatial habitat and the warming resistance of the water mass.
