FIGURE 4. Sediment characteristics (a) and dotillid density (b) on the shore in Shui Hau, Hong Kong, where Scopimera intermedia, S. curtelsona and Dotilla wichmanni coexist. H = high (~ 2.1 m + C.D.), M = mid (~ 1.8 m + C.D.) and L = low tidal height (~ 1.5 m + C.D.). n = 6 replicates for sediment characteristics and n = 8 replicates for crab density along each height. Error bars are SE. No D. wichmanni were found along the high shore during the survey in 2013. Pie charts show the relative abundance of the three dotillids along each height during the qualitative sampling in 2018 (white = S. intermedia, black = S. curtelsona, grey = D. wichmannii), numbers next to the charts are total number of crabs collected along each tidal height.
