   Abstract : Night work is vital for maintaining our 24/7 society; however, in the long run, it may have adverse health consequences like obesity and Alzheimer’s disease. By performing one of the most extensive experimental in-laboratory studies to date, I sought to investigate how sleep deprivation impacts important features like how a person responds to others and how well a person can sustain attention and wakefulness during simulated night work.

7. 5. Winter behaviour of stream salmonids: effects of temperature, light, and ice cover

   Author : Johan Watz; Larry Greenberg; Eva Bergman; John Piccolo; Svein Jakob Saltveit; Karlstads universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; stream salmonids; winter behaviour; efftect of temperatur; light; ice cover; environment; fish populations; Biology; Biologi;

   Abstract : In boreal streams, stream salmonids typically face low water temperatures and variable ice conditions during winter, and thus stream salmonids are expected to use different behavioural strategies to cope with these environmental conditions. The studies presented in this thesis explore how temperature, light intensity, and surface ice affect salmonid behaviour, with focus on drift-feeding and ventilation rates. READ MORE
