Main profile:

Plankton play a central role in aquatic ecosystems, by representing the main primary producers (phytoplankton) and a key link of energy transfer to higher trophic levels (zooplankton). Our research group is motivated to understand how planktonic communities respond to environmental gradients, and how changes in community composition are linked to ecosystem functioning. By combining empirical and experimental research (micro-and mesocosm experiments), as well as taxonomic and functional approaches, we seek for a more mechanistic understanding on the consequences of planktonic community shifts as a response to multiple stressors under global change. Another focus of our group lies in the ecology and conservation of small aquatic habitats, such as ponds and pools. While these habitats maintain exceptionally high biodiversity and are excellent model systems to test basic ecological theories, their global decline highlights the need of their evidence-based conservation.

Recent research suggests that ectothermic organisms with an omnivorous diet adapt by changing their food preference to accommodate their metabolic processes, which vary with the increasing temperature. Our research aims to understand how this change in food preference affects the dynamics of communities and the associated functioning of the ecosystem. To achieve our goal, we will examine the change in temperature-dependent food preference for the widespread invasive shrimp, Limnomysis benedeni, and its effects on the dynamics of plankton communities and the functioning of the ecosystem. We plan to achieve this by combining experimental (laboratory and mesocosm) and empirical field approaches and state-of-the-art methods used in nutritional ecology studies (stable isotope studies and molecular analyses of intestinal content).

Aims:
Our research's primary goal is to understand better the changing food preference of invasive species due to global warming. Within this, we will examine the temperature dependence of the food preference of a widespread invasive shrimp species; its effects on the temporal composition of the planktonic community and the functioning of the ecosystem; and the dependence of the effects on different climatic conditions (constant temperature difference and extreme climatic events)."
