dc.description.abstract A spatio-temporal study of the brachyuran assemblages at five marine habitats at Maavah Island, Laamu atoll, Maldives, was conducted for a period of two years from April 2001 to March 2003. Forty-seven species and a sub-species were collected from the study sites. An analysis of the species diversity of the study sites revealed that distributions of families and species were site-specific although some species have wider distributions than others and that there were seasonal variations at some of the sites. The highest species richness (S = 32) and the highest diversity index was shown by a site at north lagoon, which has complex and heterogeneous habitats. The south-east beach brachyuran community, which was low in species richness, exhibited the lowest evenness. An analysis of the constancy index of the different brachyuran communities revealed that the ratio of the species number and abundance of the constant species were considerably higher than the accessory and accidental species. To get a clearer idea about the taxocenosis of the brachyuran fauna of the atoll, the brachyuran fauna of the study sites were compared to the Laamu atoll collections of Borradaile in 1903. en_US
