Mangroves play an important role in the storage of carbon (C) and nitrogen (N) within estuarine systems, yet are being lost at an alarming rate throughout the tropics. In contrast, temperate mangroves have increased in area at many locations in recent decades. Field surveys, sediment sampling, allometry, and C and N analysis were used to determine total C and N stocks in five temperate Avicenni...
introduction estuaries are very important aquatic systems as they preserve the coastal biota, are considered as a highly dynamic ecotones that include the mixing or transition zone between freshwater saline water and are fairly appropriate places for living a wide variety of fauna and flora. an estuary is a semi- enclosed coastal area where freshwater from rivers and stream mixes with saltwater...
The U.S. Geological Survey is contributing scientific findings and synthesized results from its South Florida Ecosystem Program toward development and implementation of the Comprehensive Everglades Restoration Plan. Findings derived from hydrological and ecological studies and extensive data collected to monitor and characterize the Everglades ecosystem are being integrated into the development...
BACKGROUND Oysters play important roles in estuarine ecosystems but have suffered recently due to overfishing, pollution, and habitat loss. A tradeoff between growth rate and disease prevalence as a function of salinity makes the estuarine salinity transition of special concern for oyster survival and restoration. Estuarine salinity varies with discharge, so increases or decreases in precipitat...
The present research article highlights the metal (Cd, Cu, Pb, Zn and Fe)distribution pattern in the RSPM generated in different hot spot sites located at Kochi, theQueen of Arabian Sea. These sampling sites are categorized under three different zonesas estuarine, riverine, and coastal. Two sampling phases are selected in order to check theconsistency in pollution trend after a two year gap and...
Time series of environmental measurements are essential for detecting, measuring and understanding changes in the Earth system and its biological communities. Observational series have accumulated over the past 2-5 decades from measurements across the world's estuaries, bays, lagoons, inland seas and shelf waters influenced by runoff. We synthesize information contained in these time series to ...
