Fig. 4From: High tolerance of symbiotic larvae of Pocillopora damicornis to thermal stressLabeling index of TUNEL-positive cells in Pocillopora damicornis planulae. Planulae exposed to 27, 31, or 32 °C for 2 weeks were subjected to TUNEL assay. The labeling indices of the gastrodermis and epidermis were analyzed separately. Mean ± SD (n = 3). The asterisks show significant difference between the epidermis and the gastrodermis at each temperatureBack to article page
