In total 17 families comprising more than 29 species of larval teleost fishes were recorded in the Kromme Estuary during the study period. Dominant species included Atherina breviceps, Caffrogobius gilchristi, Diplodus sargus capensis, Gilchristella aestuaria, Glossogobius callidus, Rhabdosargus holubi and Rhabdosargus globiceps. The larval fish catch in the estuary indicated a marine dominance...

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...

To examine the relationship between lipid-degrading enzyme activities and lipid composition in estuarine sediments, lipase activities and fatty acids in surface sediments at di€erent stations along the Altamaha River were determined during a high discharge period. Freshwater sandy sediments from upstream stations were characterized by low organic carbon and low lipid contents. Sediments from th...

A three-dimensional hydrodynamic model that includes a Lagrangian particle-tracking simulation was applied to the Danshuei River estuarine system in northern Taiwan. The model’s accuracy was validated with data from1999; the results from themodel agreedwellwith empirical observations ofwater surface elevation, tidal currents, and salinity. The validatedmodelwas then used to investigate the resi...

The cycling of dissolved inorganic carbon (DIC) and the role of tidal marshes in estuarine DIC dynamics were studied in a Virginia tidal freshwater marsh and adjacent estuary. DIC was measured over diurnal cycles in different seasons in a marsh tidal creek and at the junction of the creek with the adjacent Pamunkey River. In the creek, DIC concentrations around high tide were controlled by the ...

In many European estuaries, extensive areas of intertidal habitats consist of bare mudflats and sandflats that harbour a very high abundance and biomass of macrobenthic invertebrates. The high stocks of macrobenthos in turn provide important food sources for the higher trophic levels such as fish and shorebirds. Climate change and associated sea-level rise will have potential to cause changes i...
