The effects of mangrove forests on the flow structure in estuaries have been studied in this paper. An existing two-dimensional depth-integrated mathematical model has been refined to include both the effects of drag force induced by mangrove trees and the blockage effects on the mass fluxes through mangrove forests. To investigate the influence of mangrove trees on the flow structure two ideal...

The responses of major meiofaunal taxa and nematode species assemblage to the decaying leaf litter of the mangrove Kandelia candel were investigated through a field colonization experiment in subtropical Hong Kong. Sixty-four replicate azoic and organic-free sediment cores were treated with leaf litter additions of 0x, 0.5x, 1x and 2x natural sediment organic concentration, respectively, and re...

Thirty-one sediment samples collected from 1996-2003 from the Gulf of Nicoya estuary on the northwestern coast of Costa Rica, have been obtained for PCB analyses. This is part of the first study to evaluate the PCB contamination in coastal Costa Rica. Overall, the concentrations are low, especially when compared to sediments from more temperate climates and/or sediments from more heavily indust...

Mangroves found in the intertidal zone are considered as a very productive area with high rates of organic carbon accumulation due to the presence of highly diverse marine and terrestrial flora, fauna including microbes. Organic carbon concentration and composition are closely linked to the biogeochemistry of the substrate, which occurs on the earth surface and in deep-sea sediments in various ...

Estuaries are highly degraded ecosystems throughout the world. The primary aim of this study was to investigate the biology and ecology, and the effects of contaminants on mangrove-associated micro and macroalgae, and assess their suitability in the biological assessment of estuaries. Ecological surveys over two seasonal cycles, in four estuaries in New South Wales, Austraba, the Cooks, Parrama...

Palynomorph concentrations for water-column and sediment-water interface samples are presented for two coastal deltaic systems influenced by the range of tidal regimes to assess whether any taphonomic bias exists in pollen assemblages. The localities are the microtidally influenced Mobile-Tensaw River Delta, Alabama, United States, and the mesoto macrotidally influenced Rajang River Delta, Sara...
