The Estuarine Quality Paradox, Environmental Homeostasis and the difficulty of detecting anthropogenic stress in naturally stressed areas.
TLDR
It is argued that functional characteristics either as well as or rather than structural ones should be used in detecting environmental perturbations in estuaries because over-reliance on ecosystem structural features makes the detection of the anthropogenic stress more difficult. Expand
The derivation, performance and role of univariate and multivariate indicators of benthic change : Case studies at differing spatial scales
TLDR
The present study indicates the value of indicators of benthic change for making management decisions at the various scales, and further validation is required especially, for example, where one indicator over-estimates the ecological status for poor areas and underestimates it for good areas.

Spatial variability of intertidal rocky shore assemblages in the northwest coast of Portugal
Abstract The spatial variability of rocky shore assemblages of the northwest Portuguese coast was studied in a total of 12 transects, visited twice between March and August 2003. Each transect wasExpand
Spatial patterns of benthic macroinvertebrates in intertidal areas of a Southern European estuary: the Tagus, Portugal
This study characterizes the composition and spatial distribution patterns of the benthic macrofauna in the intertidal mudflats of the Tagus estuary, western Portugal. A total of 68 species, moreExpand
Diopatra (Annelida: Onuphidae) diversity in European waters with the description of Diopatra micrura , new species
This study describes a new species of the genus Diopatra Audouin and Milne-Edwards, 1833. Diopatra micrura sp. nov., was found on the western and the southern coast of Portugal and can beExpand
Benthic biotopes remote sensing using acoustics
TLDR
Results suggest that the acoustic system provides very valuable and important data for mapping soft sediment biotopes, even in areas of relative bottom monotony such as the one analysed, but careful ground-truth is required to ensure that theoustic class splits are biologically relevant. Expand
Spiking sediment with organochlorines for toxicity testing
Sediment toxicity testing integrates responses to sediment variables and hence does not directly indicate cause and effect. One tool for determining cause and effect is sediment spiking, in whichExpand
Molecular Analysis of Bacterial Communities and Detection of Potential Pathogens in a Recirculating Aquaculture System for Scophthalmus maximus and Solea senegalensis
TLDR
Assessment of bacterial composition in the water of a recirculating aquaculture system (RAS) with a shallow raceway system for turbot and sole revealed pronounced differences in bacterial community composition, suggesting that in the systems studied there is a strong species-specific effect on water bacterial communities. Expand
Deep macrobenthic communities from Nazaré Submarine Canyon (NW Portugal)
Macrofauna community structure within Nazare Submarine Canyon is analysed and used to assess the potential effects of natural enrichment in this area subjected to accumulation of coastal sediments. AExpand
Looking for suitable biomarkers in benthic macroinvertebrates inhabiting coastal areas with low metal contamination: comparison between the bivalve Cerastoderma edule and the Polychaete Diopatra
TLDR
Assessment of wild Diopatra neapolitana and Cerastoderma edule aimed to determine the applicability of currently used biomarkers in benthic species exposed to a range of low metal and As concentrations, and showed strong species-specific responses to metals and differences in the ability to sequester metals.
