| the macrobenthic community along a mercury contamination in a temperate estuarine system (ria de aveiro, portugal). | mercury is a widely distributed environmental pollutant and a toxic element to all living organisms. this study represents an attempt to evaluate its correlation with the macrobenthic community structure in a temperate estuarine system, the ria de aveiro (portugal). the macrobenthic community structure showed significant differences along the mercury gradient. overall, the increase of mercury contamination was associated with reduced total abundance, lower species richness, and dominance of tole ... | 2008 | 18765161 |
| distribution and structure of the upper sublittoral macrobenthic communities of tróia sand beaches (setúbal, portugal) and their relationship with environmental factors. | the present study dealt with the spatial and temporal variability of the distribution of the upper sublittoral benthic macrofauna of the tróia peninsula sand beaches and its relationship with abiotic environmental factors. the existence of a relationship between the data set of macrobenthic species distribution and community structure in the sado estuary (432 individual samples) and the environmental factors in analysis was investigated. morpho-sedimentary data analysis revealed an environmental ... | 2010 | 20383379 |
| a short-term laboratory and in situ sediment assay based on the postexposure feeding of the estuarine isopod cyathura carinata. | in situ assays based on feeding depression have been proposed as sublethal assays able to assess immediate contaminant effects on key ecosystem functions, long before effects on life-history traits can be detected. the in situ peculiarities provide more realistic exposure scenarios than laboratory-controlled conditions, which is particularly relevant for estuarine ecosystems where environmental conditions are highly variable. in this context, we developed a short-term cost-effective in situ assa ... | 2014 | 25173058 |
