I study natural selection on the molecular level in a closely monitored wild population of great reed warblers Acrocephalus arundinaceus in Kvismaren in south Central Sweden. Previous results from this study system have shown that the condition and health of individual birds may be important for social mate choice and thus fitness. My primary focus is on immune system genes, in particular diversity of the genes in the major histocompatibility complex (MHC), as these are good candidates to both influence health and provide genetic advantages because of their central role in the function of adaptive immunity. I compare MHC diversity to individual fitness and a number of fitness related life-history parameters, and also to telomere attrition and known (malaria) infection status. I’m also very interested in studying sexual dimorphism in the effects of within-individual MHC variation.

As a side project, I study the mate attraction song of male great reed warblers. Previous analyses of recordings from this population have revealed a correlation between the size of the song repertoire and the relative offspring survival, which implies that the song might be an indicator of genetic quality and that females may select males with a large song repertoire to achieve indirect benefits to their offspring. I will do more field recordings and try to characterize the song in more detail to see if I can identify the specific benefits related to song quality.
