Phylogenetic trees of the parasites used in this study shaded according to their host and metabolic strategy. Green indicates plant parasites that obtain energy from carbohydrate catabolism (low nitrogen availability, L N ). Yellow indicates animal parasites that obtain energy from carbohydrate catabolism (medium nitrogen availability, M N ). Orange indicates animal parasites that obtain energy from amino acid and/or amino sugar catabolism (high nitrogen availability, H N )
