Station manager of the Netherlands Arctic Station on Spitsbergen (


Automatic flower detection and phenology monitoring using time-lapse cameras and deep learning

Five decades of terrestrial and freshwater research at Ny-Ålesund, Svalbard

Nest defence behaviour is similar between pair members but only male behaviour predicts nest survival in barnacle geese

Environmental change reduces body condition, but not population growth, in a high-arctic herbivore

Judging a reindeer by its teeth: A user-friendly tooth wear and eruption pattern recording scheme to estimate age-at-death in reindeer (Rangifer tarandus)

State dependence explains individual variation in nest defence behaviour in a long-lived bird

Contrasting consequences of climate change for migratory geese: Predation, density dependence and carryover effects offset benefits of high-arctic warming

High-Arctic family planning: Earlier spring onset advances age at first reproduction in barnacle geese

Parasitoids indicate major climate-induced shifts in arctic communities

Climate warming may affect the optimal timing of reproduction for migratory geese differently in the low and high Arctic
