Abstract

The genetic structure of Uca arcuata in Tanshui mangrove swamp of northern Taiwan was examined. Using as genetic markers, isozymes identified through starch gel electrophoresis indicate that there was moderate genetic differentiation among subpopulations within the population (F ST = .085). Gene flow appeared high when estimated indirectly (Nm = 2.69). The results suggest that the patterns of genetic structure of Uca arcuata were influenced by the interaction of local selection due to microhabitat differences and gene flow among fiddler crab colonies in the mangrove swamp.
