- The study of the factors structuring genetic variation can help to infer the neutral and adaptive processes shaping the demographic and evolutionary trajectories of natural populations. Here, we analyse the role of isolation-by distance (IBD), isolation-by-resistance (IBR, defined by landscape composition), and isolation by environment (IBE, estimated as habitat and elevation dissimilarity) in structuring genetic variation of 25 blue tit (Cyanistes caeruleus) populations. We typed 1385 individuals at 26 microsatellite loci classified in two groups by considering whether they are located into genomic regions that are actively (TL; 12 loci) or not (NTL; 14 loci) transcribed to RNA. Population genetic differentiation was mostly detected using the panel of NTL. Landscape genetic analyses showed a pattern of IBD for all loci and the panel of NTL, but genetic differentiation estimated at TL was only explained by IBR models considering high resistance for natural vegetation and low resistance for agricultural lands. Finally, the absence for IBE suggests a lack of divergent selection pressures associated with differences in habitat and elevation. Overall, our study shows that markers located in different genomic regions can yield contrasting inferences on landscape-level patterns of realised gene flow in natural populations.
- "This file contains the genotypes for 26 microsatellite loci and 1385 individuals collected in 25 populations of blue tit (Cyanistes caeruleus)"Data file contains genotyping of 1385 individuals at 26 microsatellite loci classified in two groups by considering whether they are located into genomic regions that are actively (TL; 12 loci: Cca-Tgu28, PIJ14, Tg05-053, Tg05-046, CcaTgu15, Tg13-017, CcaTgu19, CcaTgu11, CcaTgu8, Tgu07, CcaTgu14, CcaTgu7) or not (NTL; 14 loci: PK11, Pca3, Pca9, Pocc1, Pocc6, Pat-mp2-43, PK12, Ase18, Pdo5, Pca7, Pca4, Pca2, Mcyμ4, Pca8) transcribed to RNA. These individuals were captured in 25 populations located in fragmented woodlands scattered within an area of 1200 km2 in Montes de Toledo, central of Spain.MicrosatelliteDataCyanistesCaeruleus.xlsx
