We study the population, community and behavioral ecology of interacting species in fragmented and changing landscapes. Our main research system has been the parasitoids associated with the Glanville fritillary butterfly Melitaea cinxia in Finland.
Highlights from recent publications
The genetic signature of introduced wasp lineages gives us a window into what has happened in an island archipelago over the 25 years since their accidental introduction, including persistence through population bottlenecks, dispersal and interbreeding, as well as sorting among lineages depending on interaction between a hyperparasitoid and bacterial symbiont. @duplouy_anne @abhevo @Saskyavn @ParasitoidEcol

Duplouy A., Nair A., Nyman T., and van Nouhuys S. (2021. Long-term spatio-temporal genetic structure of an accidental parasitoid introduction, and local changes in prevalence of its associated Wolbachia symbiont. Molecular Ecology. doi: 10.1111/mec.16065
We assessed the potential long term and landscape-level effects of plant-pathogen herbivore-parasitoid interactions on their dynamics. We found that while there are strong and weak interactions between species, most are swamped out by spatial and temporal variation of host plant quality.
