   Notes: P values were calculated based on 9,999 randomizations. Other P values given are based on analyses of Bray-Curtis (B-C), Chord (Chd), and Euclidean (Eucl) distance metrics. Bolded P values are statistically significant at  = 0.05. Treatments include nutrient ratio (R, three levels), nutrient supply (S, two levels), light (L, two levels), and trophic structure (T, two levels).
