Résumé
Supplementary material. Figure S1. Summary of the log-likelihood values from the 20 independent runs conducted with Structure for the number of genetic clusters (K) set to a minimum of 1 and a maximum of 10. The left graph shows the log-likelihood results of the runs for each K, whereas the right graph shows Delta K plotted against K. The most likely number of genetic clusters is three using both methods. Figure S2. Comparisons of the STRUCTURE runs for K = 3 with (top) or without (bottom) the LOCPRIOR option. Table S1. Table of sampling times and associated screening for astroviruses. AstV = astrovirus, BY = Bavaria, MV = Mecklenburg Western Pomerania, NRW = North Rhine Westphalia. AstV positive samples with a length of less than 279 nt could not be assigned to a specific haplotype, but are nevertheless included in the number of AstV positive samples presented here. Database S1. R-script used for the permutation test. With this script we tested how likely it is to have no overlap in virus haplotypes across regions and whether virus haplotypes are more different between regions than expected by chance. (DOCX 318 kb)
