1. 1. How does hydropeaking and geological substrate affect aquatic macroinvertebrates in a regulated river?

   Master-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

   Författare :Andreas Vernby; [2021]
   Nyckelord :Hydropeaking; geological substrate; aquatic macroinvertebrates; EPT species; Hester-Dendy samplers; Korttidsreglering; geologiskt substrat; akvatiska makroevertebrater; EPT; Hester-Dendy-provtagare;

   Sammanfattning : Hydropower is an important source of renewable energy, but is often a cause of degradation to river ecosystems. Hydropeaking, i.e. the frequent alteration of discharge, is a process involved in hydropower generation and has been proven to affect aquatic organisms negatively. LÄS MER

3. 2. Effekter av höjd inkubationstemperatur på ventilationshastighet, som ett mått på metabolism, hos öring (Salmo trutta)

   Kandidat-uppsats, Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

   Författare :Andreas Vernby; [2019]
   Nyckelord :brown trout; salmo trutta; ventilation rate; incubation temperature; global warming; öring; salmo trutta; ventilationshastighet; inkubationstemperatur; global uppvärmning;

   Sammanfattning : The average global temperature is expected to rise by 3-5 °C at the end of the century, as a consequence of global warming. Negative effects are expected on poikilothermic animals, including fish, with changes in their physiology including metabolism. LÄS MER
