Floral hosts of leaf-cutter bees (Megachilidae) in a biodiversity hotspot revealed by pollen DNA metabarcoding of historic specimens

Fig 3. Model-adjusted means for plant species OTUs detected in pollen samples in the three regions studied. The mean number of species detected on bees from the Succulent Karoo (M. karooensis and M. murina) and the Savanna (M. felina and M. maxillosa) are lower than those on widespread bee species (M. niveofasciata and M. venusta). Means sharing a letter do not differ significantly at a 95% significance level after Sequential Dunn-Sidak post-hoc testing. https://doi.org/10.1371/journal.pone.0244973.g003 PLOS ONE Floral hosts of Megachilidae revealed by metabarcoding PLOS ONE | https://doi.org/10.1371/journal.pone.0244973 January 21, 2021 9 / 16
