Fig. 3 in Diversity and ecological relationships of Cestoda and Monogenoidea parasites of freshwater stingrays (Myliobatiformes, Potamotrygonidae), in the upper Paran´a River, Brazil

Fig. 3. Rarefaction and extrapolation of component community richness and meta-community richness of helminths species in potamotrygonids from the upper Parana´River. Sample-size-based diversity accumulation curves (with 95% confidence intervals of lower and upper limits) using hosts as unit of sampling and Hill numbers. Diversity metrics were species richness (0), Shannon Index (1) and Simpson Index (2) values.
