Frequency and extent of macroalgal contact with corals in Marine Protected Areas (MPAs) versus non-MPAs associated with three sites in Fiji.

(a) Percentage of individual corals in contact with macroalgae (letters indicate significant groupings) and (b) the proportion of coral colony perimeter (for 5 common coral species pooled) in contact with macroalgae. Numbers provide sample sizes for pooled samples at each location (data by coral type available in Fig. S1). Letters indicate significant groupings (p<0.001 for all contrasts).

(a) 与大型藻类（macroalgae）接触的单个珊瑚占比（字母标注代表存在显著分组差异）；(b) 汇总5种常见珊瑚物种后，与大型藻类接触的珊瑚群落周缘占比。各采样地点合并样本的样本量以数字标注（按珊瑚类型分类的详细数据可参见补充图S1），字母用于标注显著分组（所有组间对比的p值均小于0.001）。
