Be cool: hydro-physical changes and fish responses in winter in hydropower-regulated northern streams
Heggenes, Jan; Alfredsen, Knut; Adeva Bustos, Ana; Huusko, Ari (Research report, 2016-06-21)In the seasonal climates of northern Europe and North America, winter is considered a particularly ecologically challenging season for aquatic organisms in natural streams. They experience reduced flow and freezing in ... -
Hydropower‐driven thermal changes, biological responses and mitigating measures in northern river systems
Heggenes, Jan; Stickler, Morten; Alfredsen, Knut; Brittain, John Edward; Adeva Bustos, Ana; Huusko, Ari (Peer reviewed; Journal article, 2021)Water temperatures control life histories and diversity of aquatic species. Hydropower regulation, particularly in high head systems, alters natural water temperature regimes, which may have profound and long‐term impacts ... -
Stay cool : temperature changes and biological responses in hydropower-regulated northern stream systems
Heggenes, Jan; Alfredsen, Knut; Brittain, John E.; Adeva Bustos, Ana; Huusko, Ari; Stickler, Morten (Publication series from University College of Southeast Norway;21, Research report, 2018-01-17)In the seasonal climates of northern Europe and North America, water temperature variations are ecologically challenging for aquatic organisms in natural streams. In winter, low water temperature and ice conditions becall ...
