Parameters estimated under the selective neutrality tests and the sudden expansion model for the East African giant mud crab (Scylla serrata) based on cytochrome oxidase subunit I sequences.

D = Tajima's D, FS = Fu's FS, HRI = Harpending's raggedness index, SSD = sum of squared deviations, p = p-values. For sample sites, see Table 1 and Fig 1.D为塔吉马D统计量（Tajima's D），FS为傅氏F统计量（Fu's FS），HRI为哈彭登崎岖度指数（Harpending's raggedness index），SSD为平方偏差和（sum of squared deviations），p为p值。采样位点详见表1与图1。
