Stress interactions under climate change

Global climate change is predicted to increase the frequency and intensity of extreme weather conditions, such as summer heat waves. The effects of such extreme weather events on natural populations may, however, depend on their interactions with other stressors, such as natural enemies and chemical pollution. In this project, we examine the consequences of heat waves using a freshwater snail Lymnaea stagnalis as a model. The specific aims of the project are to test (1) the interacting effects of high temperature, chemical stress and parasitism on organismal performance, (2) their long‐term consequences on survival and lifetime fitness, and (3) the role of the above effects on ecosystem processes that snails mediate through consumer‐resource interactions.
