Figure 1From: Coral bleaching under thermal stress: putative involvement of host/symbiont recognition mechanismsZooxanthellae density measured during the temperature stress. Dark grey histograms refer to the stressed set, light grey histograms to the control set. The Kruskal-Wallis H-test shows significant differences in the stressed set (P < 0.05). The significant differences (P < 0.05) were identified using the Mann-Whitney U-test and indicated by a star.Back to article page
