•Abundance counts determined as follows:

•

•

•whole gastropod shells and fragments with the top of the spire preserved were counted as individuals; valves (left or right) and umbonal fragments were counted and their number divided by 2. parietal plates of barnacles were counted and their number divided by 6 when dealing with Balanus and 4 when dealing with Verruca
