| Experimental clearing and routine cleaning of oil platforms favored increased abundance of Watersipora subatra, recruitng in the cleared area (Viola et al. 2018). Viola et al. (2018) suggest the retention of oil platforms as artificial reefs could favor W. subatra. Removal of the upper portions of the platforms might reduce their potential as a source for coastal populations of the bryozoan. | ||
