Foraging and Movement Ecology
Scaling up from processes at the individual level to patterns at the population level.
Research
We try to understand patterns at the population level from foraging and movement processes acting at the individual level. We use optimality principles, which are founded in foraging theory and migration theory, to model animal migration and site use. The approach taken is a combination of field work, experiments and modelling. Our main study species are herbivorous birds (geese and swans), that migrate between the arctic tundra and the temperate region, and of which a large proportion of the flyway population winters in the Netherlands (Bewick’s swan, barnacle goose, dark-bellied brent goose, pink-footed goose, white-fronted goose).
Climate change is expected to be prominent in the Arctic and at the same time land-use changes are continuing in the temperate region; we study how these birds are responding to these changes. The idea behind using optimality principles is that these will still be valid under new conditions, so we might be able to predict future population distribution and abundance from these principles. In that sense we are developing tools that can be used in environmental impact assessments and adaptive management.
