The majority of identifiable genera were found at multiple locations in the park but their relative abundance varies. (A) The relative distribution of the phyla at each sample site. (B) Three Venn diagrams were prepared to show the distribution of genera amongst the sample sites, represented into groupings of ‘all’, ‘photosynthetic’ and ‘heterotrophic’. See Figure 1 legend for lists of algal and heterotrophic protist phyla. Diagrams were produced using InteractiVenn (Heberle et al. 2015).
