Effects of shoreline development and freshwater discharge on nekton assemblage and trophic structure in a northern Gulf of Mexico estuary
… and their responses to abiotic shifts along an estuarine gradient. Overall, I noted a decrease in richness and diversity during HFD and a more homogenous nekton assemblage along the estuarine gradient. No benefit to nekton assemblage was detected along LS, although habitat type was broadly less …

Interactions of Trace Metals with Plastic Production Pellets in the Marine Environment
… added to suspensions of pellets in seawater and estuarine water were performed in order to understand the extent and rates of trace metal adsorption to pellets. Langmuir modelling of adsorption isotherms in seawater indicated a range of maximum values for the accumulation of trace metals on …

The Distribution and Reactivity of Organochlorines in Estuaries
… the behaviour of these organochlorines (OCs) in estuarine systems. Field surveys were conducted at UK estuarine (Humber, Clyde and Dee) and coastal locations. Sediments were analysed for OCs and a range of chemical and physicochemical properties (trace metals, organic carbon content, specific …

Investigations of Phytoplankton Diversity in Chesapeake Bay
… flora and spatial heterogeneity along the estuarine gradient with high species turnover between salinity regions. Alpha-diversity was greatest in freshwater and polyhaline regions, and minimal in lower mesohaline waters. Multivariate ordination analysis identified regional differences …

Estudio de las interacciones microbianas de comunidades planctónicas en gradientes ambientales
… por las variables ambientales es estudiando los gradientes ecológicos, que son cambios espaciotemporales progresivos de características bióticas y / o abióticas dentro de un ecosistema. Muchos ecosistemas presentan notables gradientes ambientales, en los que las interacciones entre las …
