Rarefaction curve (bold, solid line) and the estimators Chao2 (thin solid line) and ICE (dashed line) of yeast operational taxonomic unit (OTU) richness found in the floral nectar of 20 Linaria vulgaris populations sampled across an urbanization gradient in the vicinity of Leuven, Belgium. The sequences were grouped into OTUs based on 97 % identity at the large ribosomal subunit gene
