RESEARCH INTEREST

I try to understand and predict patterns at the population level (i.e., animal distribution and abundance) from processes acting at the individual level. Within an optimality framework, I study decisions of where and when to move: how animals (should) explore their surroundings and exploit their resources. The scale of movement varies from 10^0-10^7 body lengths. In the course of time, my main study system has changed from otters foraging on bottom-dwelling fish, beavers foraging on willows, swans foraging on pondweeds to, more recently, geese foraging on (sea)grass. Currently the focus is on arctic-breeding waterbirds, which migrate through and to the Netherlands in numbers of international importance (Bewick’s Swan, Pink-footed Goose, Brent Goose). How will these birds respond to climatic changes in the Arctic and land-use changes in the temperate region? The approach taken is a combination of field, experimental and modelling work.
