Costa Biología fiddler crab reproductive cycle Brazilian mangroves population structure Population and reproductive biology were studied in three populations of the crab Uca burgersiHolthuis, 1967, in the Indaiá, Cavalo and Ubatumirim mangrove forests (Ubatuba, São Paulo State, Brazil).Crabs were collected during low tide (August 2001 through July 2002), by digging the sediment, with a standardcapture effort (two persons for 30 min.). Carapace width was measured, and gonad developmental stage wasrecorded from all specimens. U. burgersi was most abundant in the Cavalo mangrove, where the largest malewas found. Juvenile crabs were found year-round at all three sites. However, the ratio of ovigerous femaleswas very low, even null in the Cavalo mangrove. The gonad development rate indicated that U. burgersi wasreproducing continuously, but more intensively during spring and summer, with recruitment occurring in winter.The synchrony between the populational and reproductive biology in the three areas showed that local featureswere not the limiting factors. It is suggested that this species is a habitat generalist. Rev. Biol. Trop. 55 (Suppl.1): 55-70.
