δ15N values from Reynard islet and Surprise islets in coral tissues and zooxanthellae. Stars denote significantly higher values compared to the reference station (0.05 significance level, statistical results for coral and zooxanthellae are the same). Note that the distances of sampled sites from the shore are different between islets.
