Karl Filipsson

I study the effects of warmer winters, as a consequence of climate change, on predator-prey interactions and early life-history performance in fish, mainly brown trout (Salmo trutta) and burbot (Lota lota). My main focus is behavioral ecology, but I am also interested in physiological stress responses and molecular changes, such as mRNA activity. In addition, I have been involved in projects examining the effects of parasitic larvae of the endangered freshwater pearl mussel (Margaritifera margaritifera) on brown trout.

I am responsible for the River Ecology and Management research group’s blog, nrrv.se. If you want to read more about our work, check out the blog here!
