Thermal and hydrologic responses to climate change predict marked alterations in boreal stream invertebrate assemblages
Abstract Air temperature at the northernmost latitudes is predicted to increase steeply and precipitation to become more variable by the end of the 21st century, resulting in altered thermal and hydrological regimes. We applied five climate scenarios to predict the future (2070–2100) benthic macroin...
