Polar Benthic Ecology

Research Interest

The Arctic is warming about twice the rate than the global average, most prominently visible in the drastic decrease of sea ice extent and thickness. We are interested how these changes affect specifically the benthic macro- and megafauna communities. By applying a biological trait approach on a pan-Arctic scale we aim to get insight in the benthic functional variability, identify the functions and regions most susceptible to change, and predict benthic ecosystem functioning in a future, seasonally ice-free Arctic Ocean.
