Mean coral larval settlement of brooding species in response to CYPRO. Settlement was monitored after one and two days. Note that CYPRO has a very low water solubility and thus the concentration of the pigment is specified in µg cm− 2. Pictures in the upper right corner of each graph show a corresponding coral recruit after 2 days. Error bars represent standard error (SE). Differences within each time point between the negative control and the different CYPRO treatments as well as the positive control were evaluated per experiment using non-parametric Kruskal-Wallis tests, followed by pairwise Dunn tests (α = 0.05). Asterisk indicate the level of significance difference between NEG control and CYPRO treatment or POS control within each timepoint, with n.s. = not significant; * = p > 0.05; ** = p > 0.005 and *** = p > 0.001. Leptastrea transversa and purpurea: 3 replicates with 5 larvae each, Pocillopora acuta: 3 replicates with 3 larvae each and Favia fragum: 6 replicates with 5 larvae each.
