1. Experimental removal of anoxic hypolimnion conditions in a lake increases perch growth
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Global warming leads to an increased browning of lakes across the northern hemisphere. This browning can due to benthic light-limitation cause hypoxic bottom conditions which can have negative impact on the fish production in the northern lakes. LÄS MER
2. Diet variability in Eurasian perch (Perca fluviatilis) as a response to environmental variables along a latitudinal gradient
Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildningSammanfattning : Climate change is expected to have a profound impact on freshwater fish communities, especially at higher latitudes. In this study I investigated potential effects of climate change on the niche structure of Eurasian perch (Perca fluviatilis) by looking at their diet across a latitudinal gradient and at varying light climate.

3. Effects of global warming on Eurasian perch (Perca fluviatilis) in the Baltic Sea : does the growth response to increased temperatures differ along a latitudinal gradient?
Master-uppsats, SLU/Dept. Of Aquatic ResourcesSammanfattning : Anthropogenically caused climate change, i.e. global warming, is anticipated to affect all living organisms. Particularly ectotherms are predicted to show strong responses to the increased warming, as their body temperature closely tracks ambient temperatures and because body temperature profoundly affects many physiological functions e.

4. Remotely monitoring heart-rate and feeding behaviour of fish by using electronic sensor-tags
Master-uppsats, SLU/Dept. of Wildlife, Fish and Environmental StudiesSammanfattning : Modern electronic sensor tags (BioLoggers) can collect high resolution data on movement and physiology of fish. These tools make it possible to remotely monitor physiological stress responses as well as complex behaviours, such as feeding and hunting, in free swimming wild fish, data that often is difficult to collect by other means.

5. The influence of northern pike on the diet of Eurasian perch
Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskapSammanfattning : Top predators in aquatic ecosystems often have strong top-down effects on the ecosystem. Northern pike (Esox lucius) has been documented to cause whitefish (Coregonus lavaretus) populations to diverge into different ecomorphs. LÄS MER
