Karl Filipsson

I study how warmer winters, as a consequence of climate change, affect predator-prey interactions and early life-history performance in fish, mainly brown trout (Salmo trutta), Atlantic salmon (Salmo salar) and burbot (Lota lota). My main focus is fish behavior, but I am also interested in physiological stress responses and gene expressions. In addition, I have also been involved in projects aimed to examine the effects that parasitic larvae of the endangered freshwater pearl mussel (Margaritifera margaritifera) have 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!
