Microsatellite markers

This Table lists the alleles found in each sampled individual (specified by ID numbers) on the Basis of six microsatellite marker

Genetic structure within the R and L genome

Genetic differentiation within the R and L genome of water frogs of the Pelophylax esculentus complex, according to Bayesian analyses implemented in the program STRUCTURE. The proportion of membership (parameter q according to Pritchard et al. 2000) of each individual in each of the two (R genome) and four (L genome) inferred clusters is shown

Samples for microsatellite and mt DNA analysis

The Table summarizes which samples have been analyzed with microsatellites and/or mtDNA sequencing. Given are ID numbers, names and coordinates of samples sites an genotypes of frog

Origin and number of frogs used for mtDNA analysis

Populations, geographic coordinates and sample sizes of samples used for mtDNA analysis. The column “Microsat No.*” refers to the numbering of populations in Table S1 (new), where only populations used in microsatellite analyses are listed. Types of mtDNA are abbreviated as follows: les = lessonae-type, rid = ridibundus-type, ber = bergeri-type, cf. bed = cf. bedriagae-type

mt DNA haplotypes across genotypes and populations

Supplement to Figure 8, showing the distribution of mtDNA haplotypes across genotypes and population types. Asterisks (*, **) indicate novel findings of the respective type of mtDNA in mixed-ploidy populations [24]* (Untermassfeld, Germany) and [52]** (Gaidary Iskov, Ukraine)

Study sites, sample sizes and population composition

Geographic coordinates, sample sizes and genotypic composition of water frog populations sampled for microsatellite analysis. Classification was based on microsatellite results and was complemented by additional information on the population through personal observation (e.g. on presence of parental genotypes even though none were captured for sampling). nL represents the number of individuals used for the L genome data set, nR stands for the number of individuals used for the R genome data set. N represents the number of individuals used in total from the respective population. Percentages account for the proportion of genotypes within N. Please note that the population marked with * is a subsample from a larger sample. Individuals from this population used in this study were selected to represent the proportion of genotypes in the larger original sample, which partly resulted in a deviation in sample size between nL and nR
