Mangrove assemblage was the most important spatial factor affecting the distribution
and abundance of these species. Perisesarma sp. was most abundant in mid- and low-intertidal assemblages,
whereas N. meinerti and Episesarma sp. were largely limited to high intertidal assemblages.
In many cases, crab species occurrence and abundance were specific
to certain assemblages, areas, aspects, and times during the two-year study period,
which probably reflects the specificity of species to particular environmental conditions
