Fig. 7

Principal component scores for individual ponds are coloured according to conductivity, while loadings, representing the distributions of A steranes and B 18S rRNA genes, are coloured in dark purple. Certain 18S rRNA gene variables plotted very closely together near the origin and their names are abbreviated. Cr is short for Cryptophyceae, Ce is short for Centrohelida, and Ha is short for Haptophyta.
