Several studies conducted at the scale of islands, or small sections of continental coastlines, have suggested that mangrove habitats serve to enhance fish abundances on coral reefs, mainly by providing nursery grounds for several ontogenetically-migrating species. However, evidence of such enhancement at a regional scale has not been reported, and recently, some researchers have questioned the...

Reclaimed coastal areas were mostly used for agricultural purposes in the past, while land-use conversion was initiated recent decades eastern China. Elucidation of effects on soil properties and stoichiometry is essential addressing climate change ecological conservation. In this study, five types a reclaimed area chosen to compare differences stoichiometry, which comprised paddy, upland, upla...

Stomach contents from 449 schoolmaster snapper, Lutjanus apodus, from southwestern Puerto Rico were examined. Hierarchical cluster analysis identified two primary trophic groups: ::;70 mm FL and >70 mm FL. Small L. apodus (::;70 mm) fed almost exclusive]y on crustaceans (89% by weight; 95% by numbcr; 98% frequency of occurrence), particularly amphipods and crabs, By contrast, L. apodus greater ...

heavy metals in the surface sediments of the two coastal ecosystems of cochin, southwest india were assessed. the study intends to evaluate the degree of anthropogenic influence on heavy metal concentration in the sediments of the mangrove and adjacent estuarine stations using enrichment factor and geoaccumulation index. the inverse relationship of cd and zn with texture in the mangrove sedimen...

Overlying water, sediment, rhizosphere sediment and mangrove seedlings in the Futian mangrove forest were analyzed for heavy metals. The results showed that mangrove plant acidified sediment and increased organic matter contents. Except for chromium (Cr), nickel (Ni) and copper (Cu) in Aegiceras corniculatum sediment, heavy metals in all sediments were higher than in overlying water, rhizospher...

The mangrove environment is not globally homogeneous, but involves many environmental gradients to which mangrove species must adapt and overcome to maintain the familiar structure and physiognomy associated with the mangrove ecosystem. The stature of mangroves, measured by tree height, decreases along the following environmental gradients from low to high salinity, low to high wind speed, high...

To assess the occurrence, spatial distribution and species composition of small infauna on a mangrove shore, core samples were taken along a transect in Missionary Bay at Hinchinbrook Island, north-east Australia. Three sites were arranged within the mangrove forest and one site was located in an adjacent mudflat. The sites were surveyed four times between November 1988 and October 1989. Based ...
