Values for nuclear and mitochondrial pairwise fixation index (FST - Wright, 1951) between individuals of different roosts are shown below the diagonal with the associated p-value (based on 1000 permutations) indicated above the diagonal. Significant values are marked with*. Nuclear indexes are based on analyses of 12 microsatellites. Mitochondrial indexes are calculated using sequences of concatenated HVI and HVII fragments. Between colonies mean nuclear distance is indicated below the diagonal as calculated with MEGA 6 using T92 model of nucleotide substitution with the standard error indicated above the diagonal.
