“…Mangrove ecosystems have been proposed as an ideal location to study relationships between biodiversity and ecosystem functioning because of their relatively low plant species diversity and density (Osborn & Polsenberg 1996). Intact mangrove ecosystems provide valuable ecological and socio-economic goods and services to man 1 Corresponding author.…”

Baseline ecological studies of pristine mangroves are important for monitoring, management and conservation of mangrove ecosystems. Diversity, density, biomass and community structure of crab and molluscan macrofauna were studied in a near-pristine mangrove forest in Sematan, Sarawak. In each of the nine 100-m2 plots, six 15-min catching periods were used to collect crabs and three 1-m2 quadrats were sampled for molluscan epifauna. Environmental variables and vegetation were also recorded in each 100-m2 plot. Thirty-one crab species and 44 molluscan species were recorded, including a few species not previously reported from Sarawak. Crab community structure was correlated with topographical height and surface water pH and salinity. Gastropod community structure was correlated with redox potential of water at depth, topographical height, surface water pH and leaf litter. Crab community structure and species number were positively correlated with tree and seedling community structure and diversity, suggesting that the mangrove vegetation is important to the crab fauna as a habitat and food supply. Molluscan abundance was positively correlated with sapling diversity and negatively correlated with the numbers of mangrove associates and tree species. The young leaves on mangrove saplings may provide a better food source than those on mature trees or mangrove associates. The data from this study provide a valuable baseline for future use at this site and for comparison with more degraded mangrove habitats elsewhere in South-East Asia.

“…Tan and Ng (1994) suggested that the maintenance of high crab species diversity is integral to the health of the mangroves. Natural and human-induced disturbances pose serious threats to the functioning of mangrove ecosystems (Osborn and Polsenberg 1996). The reaction of natural ecosystem to disturbances is often discontinuous, determined inadvertently and hence unpredictable (Holling et al 1995).…”

Summary:The present study investigates the effect of different habitat attributes on brachyuran crab diversity in two different study sites in the Sundarban mangrove, India. The two sites differ in the level of anthropogenic intrusion and in the age of the mangrove forest. Seasonal changes in the environment and in brachyuran faunal abundance were recorded for three years. Species composition varied between the two habitats irrespective of season. The habitat heterogeneity and the recorded crab community was analysed by several univariate and multivariate statistical techniques. The newly replanted mangrove site showed lesser diversity than the natural one. Ocypodid crabs, mainly Uca rosea, dominated both study sites, whereas Uca triangularis was totally absent from the replanted site. Canonical correspondence analysis showed that the total acidity, total alkalinity, pH content of water, total dissolved solids, inorganic phosphate content of water, soil specific gravity, soil density and the physical constructions of the habitat play a crucial role in moderating the crab community structure. This study reveals that brachyuran crab diversity can be used as a potential indicator of the alterations of mangrove habitats.Keywords: crab diversity; canonical correspondence analysis; edaphic qualities; habitat heterogeneity; hydrological parameters; mangroves. Cambios temporales en la diversidad de los cangrejos braquiuros a lo largo de un hábitat heterogéneo del manglar indio de SundarbanResumen: El presente estudio investiga el efecto de las diferentes características de hábitat sobre la diversidad de los cangrejos braquiuros en dos lugares diferentes del manglar Sundarban, India. Los dos sitios difieren en el nivel de intrusión antropogénica, así como en la edad del bosque de manglar. Se registraron cambios estacionales en el medio y en la abundancia de la fauna de braquiuros durante tres años. A pesar de las diferencias estacionales, la composición de especies difiere en los dos hábitats. Se analizó la heterogeneidad del hábitat y la comunidad de cangrejos mediante técnicas estadísticas univariantes y multivariantes. La zona de manglares replantada recientemente mostró menor diversidad que la zona natural. Los cangrejos ocipódidos, principalmente Uca rosea, dominaron en ambas zonas de estudio, mientras que Uca triangularis estuvo totalmente ausente en la zona replantada. El análisis de Correspondencia Canónica (CCA) mostró que la acidez total, la alcalinidad total, el contenido de pH del agua, los sólidos totales disueltos (TDS), el contenido de fosfato inorgánico del agua, el peso específico del suelo, la densidad del suelo, junto con las construcciones físicas del hábitat desempeñan un papel fundamental en la estructura de la comunidad de cangrejos. Este estudio revela que la diversidad de los cangrejos braquiuros puede ser utilizada como un potencial indicador de las alteraciones de los hábitats de manglares.Palabras clave: diversidad de cangrejos; análisis de correspondencia canónica; cualidades edáficas; hetero...
