Casper van LeeuwenDr. Casper H.A. van Leeuwen

Aquatic Ecologist studying species movement and species interactions in freshwater ecosystems. In my Junior Group we aim to understand how, why and when organisms move – and how their presence or absence affects aquatic food webs, populations and communities. We study phytoplankton, zooplankton, aquatic invertebrates, a wide range of plant species, fish and waterbirdsin the context of species interactions. We ask questions on both ecological and evolutionary timescales. Methods include field- and lab-based experiments, population genetic analyses, acoustic telemetry and advanced statistics. Welcome to my website! Please do not hesitate to contact me.
