The Glanville fritillary (Melitaea cinxia) study system in the Åland Islands is exceptional in terms of the resources available for research. The ecological study has been continued since 1991, and the annual large-scale survey of the entire metapopulation provides unique long-term ecological data at a landscape level. The butterfly laboratory at the Lammi Biological stationmakes it possible to rear butterflies and host plants in a large scale and conduct experiments throughout the year. Finally, the recently developed genomic resources make genome-wide studies feasible. The primary aim of this project is to find genetic loci associated with life history traits in the Glanville fritillary, with a special focus on larval development and flight metabolic rate. Currently, another line of research compares the well-studied metapopulation in the Åland Islands with a small, completely isolated population on the small island of Pieni Tytärsaari (PT) in the Gulf of Finland. This population has persisted in spite of large genetic load accumulated over the past 100 years.
