I’m interested in understanding how and why organism respond to human-induced environmental changes the way they do, and what the consequences are for populations, communities and ecosystems. The research topics range from effects of eutrophication and climate change on shallow water communities to the impact of light pollution on insects. In addition, I attempt to synthesise the field through reviews, both traditional and systematic, and build conceptual frameworks to generate predictions and guide empirical and theoretical work.

I am investigating the impact of climate change on host-parasite interactions using the three-spined stickleback and its cestode parasite Schistocephalus solidus. By combining field observations with lab experiments and theoretical models, I aim to build up a real-world picture of how population structure and individual-variability determine the impact of parasitism on population viability in unpredictable environments.

My research interests are related to zooplankton and their adaptation to rapid human induced environmental changes, such as eutrophication and climate change. I am currently interested in the size and diversity of the zooplankton resting egg bank in the Baltic Sea, and the possibility to resurrect eggs that are produced during different periods of the Baltic eutrophication history.

Linnea Kivelä did her Master’s work on the impact of light pollution on reproduction in glow-worms, focussing on the impact of different qualities of artificial light. She is now continuing as a PhD student, investigating the role of artificial ligth as an ecological trap and the the degree to which this depends on the characteristics of the light,
