  1. * (incl. Toxotrypana curvicauda).
  2. **) using the empirically established threshold of 1.50 differentiates between R. cingulata and R. turpiniae, increasing the N OTUs of Rhagoletis ‘Including Singletons’ to 13.
  3. “N OTUs” indicates the number of OTUs obtained using the corresponding threshold. “mix low”, “mix high”: the corresponding thresholds for each group were taken to establish the number of OTUs for the combined data set (All).
