Integrity of benthic assemblages along the arctic estuarine-coastal system

Spatial and Temporal Changes in Subtidal Benthic Crustaceans Along a Coastal River-Estuarine Gradient in Mississippi

Benthic crustaceans were collected monthly between 24 August 1985 and 20 September 1986 from tidal freshwater (TFW), oligohaline (OH) and mesohaline (h4H) sites in Old Fort Bayou, a black-water tidal river of the Biloxi Bay estuary, Mississippi. Salinity varied seasonally and spatially and was primarily related to variations in rainfall during this study. Reduced rainfall after October 1985 res...

Trace metal contamination and benthic assemblages in Subaé estuarine system, Brazil.

Biomass spectra in benthic fish assemblages in the Benguela System

B~ornass spectra in the different benthic fish assemblages at depths between 100 and 800 m off the coast of Namibia were studied over a p e r ~ o d of 3 yr These assemblages were located in areas spanning active upwelling centres on the shelf and zones of lower productiv~ty on the lower slope. The slopes of the curves for the normallzed size distributions were related to zonal productivity and ...

An Estuarine Benthic Index of Biotic Integrity for the Mid-Atlantic Region of the United States. I. Classification of Assemblages and Habitat Definition

An objective of the Mid-Atlantic Integrated Assessment Program (MAIA) of the U.S. Environmental Protection Agency is to develop an index for assessing benthic community condition in estuaries of the mid-Atlantic region of the United States (Delaware Bay through Pamlico Sound). To develop such an index, natural unimpaired communities must first be identified and variability related to natural fa...

Coastal urbanization and the integrity of estuarine waterbird communities: Threshold responses and the importance of scale

Estuarine ecosystems are becoming increasingly altered by the concentration of human populations near the coastline, however a robust indicator of this change is lacking. We developed an index of waterbird community integrity (IWCI) and tested its sensitivity to anthropogenic activities within 28 watersheds and associated subestuaries of Chesapeake Bay, USA. The IWCI was used as a tool to gain ...
