Marcel Visser

Marcel Visser was one of the first researchers to demonstrate how climate change disrupts the plant and animal food chain. One of his discoveries is that when oaks bear leaves earlier in spring, the food supply of winter moth caterpillars also peaks before time and the great tits that depend on them arrive too late to find caterpillars to feed their fledglings. Visser’s research is exceptional in that it combines different biological disciplines, from the genetics of organisms to populations and ecosystems, and from field trials to lab experiments and models.
