Background and activities
I am a PhD student from the Netherlands working on the project 'Evolution in a Changing Climate' (EVOCLIM), where we ask the question: how are populations able to adapt to a changing environment? Using a unique set of long-term studies on European hole-nesting passerines, I explore how population demography, phenotypic selection and life-history traits vary in space and to what degree temporal variation in those ecological parameters can be explained by temporal variation in the environment.
I am also involved in:
- SPI-Birds Network & Database, an initiative to create a community-defined, standardized method for formatting data on hole-nesting passerines (and other birds) making it much easier to exchange data and ideas within the network.
- sTraitChange, a sDiv collaborative project with the focus on: how do trait responses to climate change translate into demographic rates and population dynamics?
I have participated in the organization of three conferences in Trondheim and Røros:
- EvoDemo7, the 7th Annual Meeting of the Evolutionary Demography Society (Røros, Oct 6 - 11, 2020)
- Nordic Oikos conference (Trondheim, Feb 19 - 22, 2018)
- Eighth International Hole-Nesting Birds Conference (Trondheim, Oct 30 - Nov 2, 2017)
