Here, we use a metapopulation model to predict the distribution of the Glanville fritillary butterfly during 22 years across a large heterogeneous landscape with 4,415 small dry meadows. The majority (74%) of the 125 networks into which the meadows were clustered are below the extinction threshold for long-term persistence. Among the 33 networks above the threshold, spatial configuration and habitat quality rather than the pooled habitat area predict metapopulation size and persistence, but additionally allelic variation in a SNP in the gene Phosphoglucose isomerase (Pgi) explains 30% of variation in metapopulation size. The Pgi genotypes are associated with dispersal rate and hence with colonizations and extinctions. Associations between Pgi genotypes, population turnover and metapopulation size reflect eco-evolutionary dynamics, which may be a common feature in species inhabiting patch networks with unstable local dynamics.11engcc_byinfo:eu-repo/semantics/openAccessHABITAT FRAGMENTATIONMELITAEA-CINXIAAREA RELATIONSHIPSLARVAL DEVELOPMENTFLIGHT METABOLISMATLANTIC FORESTDISPERSAL RATEDYNAMICSEXTINCTIONSEVOLUTIONEcology, evolutionary biologyArticleopenAccess21d1f0ab-9648-4e2e-bb7b-4f2925dad43685013202260000394222600001
