I am an ecologist with a passion for migratory birds and the Arctic, with a special focus on the African-Eurasian flyway. My research revolves around the effects of climate warming on fitness and movement of migratory species. I study how climate warming impacts reproduction and offspring growth of migratory species, both directly via increasing temperatures as well as via changing interactions with their food, and whether species are able to compensate for such changes by adapting their movement and migration behaviour. Based on this knowledge I identify which conservation actions are needed along the flyway to safeguard migratory bird populations in a warming climate, and engage with conservation organisations to disseminate this information. I use tracking techniques in combination with long-term datasets, field experiments and theoretical models to link individual-level responses to predictions at the population level. I capitalize on a large international network to study the effects of climate warming in a range of migratory birds across the entire Arctic region, in order to maximise the potential use of my results for conservation management.
Specialist Group work
The main aim for our group is to update the information on population status of Northern Hemisphere goose populations. This includes the compilation of population counts as well as counts of juvenile production. This information is vital to understand the changes in conservation status of goose populations. Besides this main goal, we have several projects aimed at specific conservation issues regarding specific species.
Understanding threats to Goose
Geese face both known and emerging threats. GSG studies these at local and global levels.
Geese on the IUCN Red List
GSG contributes information and expertise to status assessments for the IUCN Red List of Threatened Species to inform conservation efforts.
