From: In situ changes of tropical crustose coralline algae along carbon dioxide gradients
Violin plot showing changes in the frequency of settlement tiles with CCA present on their bottom-sides, along the pH gradient.
The dark and light grey areas indicate the densities of observations of tiles with and without CCA, respectively, both after 5 month (5 M.: N = 120) and after 13 month of deployment (13 M.: N = 116). The rugs indicate the median pH for each tile, i.e. the pH to which the tiles were exposed to in the field. The transition from CCA presence to absence is steep at a pH of ~7.8.
