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.

Planned duration: 2021-2025
Summary: 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 […]
