STRUCTURE analysis for all species. STRUCTURE results for a) Spinturnix myoti, b) Myotis myotis c) Spinturnix bechsteini d) Myotis bechsteinii. Colony names correspond to the abbreviations given in Tab. 2. Results are shown for the number of subpopulations with the best ΔK and highest log likelihood (S. bechsteini K = 7, M. myotis K =3). In S. myoti and M. bechsteinii no discernable population sub-structuring was found, with strongest support being found for K = 1. For these species K = 2 is shown to illustrate the lack of structuring when multiple subpopulations are assumed.
