*OTU, operational taxonomic unit; TERF, University of Sydney’Tropical Ecology Research Facility (New South Wales, Australia).
†Body condition scores are residuals calculated from regression of ln-transformed body mass on ln-transformed body length.
‡Colonic lesion severity is a conglomerate statistical measure (principal component) of 4 scores of lesion severity. Higher values indicate increased severity.
