The Biodiversity of the Mediterranean Sea: Estimates, Patterns, and Threats
The Mediterranean Sea is a marine biodiversity hot spot. Here we combined an extensive literature analysis with expert opinions to update publicly available estimates of major taxa in this marineExpand

The Magnitude of Global Marine Species Diversity
BACKGROUND The question of how many marine species exist is important because it provides a metric for how much we do and do not know about life in the oceans. We have compiled the first register ofExpand

Development of a tool for assessing the ecological quality status of intertidal coastal rocky assemblages, within Atlantic Iberian coasts
Abstract The aim of this paper is to develop a new methodology for assessing the quality of coastal waters along the Atlantic Iberian coasts, based upon Basque coast rocky intertidal assemblages,Expand

Extreme variation in the concentration of trace metals in sediments and bivalves from the Bilbao estuary (Spain) caused by the 1989-90 drought.
Intertidal sediments and bivalves Scrobicularia plana from Bilbao estuary (Spain) were repeatedly sampled during and after the 1989-90 drought. The organic content (OC) and the concentration of mostExpand

Biomonitoring of metals under the water framework directive: detecting temporal trends and abrupt changes, in relation to the removal of pollution sources.
Temporal trends in metal concentrations, i.e. Ag, Cd, Cu, Cr, Hg, Ni, Pb and Zn, measured in soft tissues of Mytilus galloprovincialis mussels and Crassostrea gigas oysters collected from estuarineExpand

Detecting human mitigation intervention: effects of sewage treatment upgrade on rocky macrofaunal assemblages.
The effectiveness of secondary vs primary treatments of wastewaters in mitigating the effects of sewage discharge on the multivariate structure and diversity of rocky invertebrate assemblages wasExpand

Concordance degrees in macrozoobenthic monitoring programmes using different sampling methods and taxonomic resolution levels.
In summer 1997, an intensive survey on the hard bottoms of the 'Abra de Bilbao' (N. Iberian Peninsula) was carried out in the context of the macrozoobenthic monitoring programmes developed to assessExpand

Reducing effort in the use of benthic bioindicators
Abstract Hard-bottom invertebrates were visually sampled in a man-modified bay during a harbour enlargement scheme. Several environmental variables were repeatedly measured. Faunal assemblages wereExpand

Intertidal macrofaunal communities in an intensely polluted estuary
The Bilbao estuary (northern Spain) has suffered a serious environmental deterioration due to industrial and domestic discharges during decades. A total of 21 sampling stations were selected in orderExpand

Changes in the sublittoral faunal biomass induced by the discharge of a polluted river along the adjacent rocky coast (N. spain)
Sublittoral hard bottom assemblages in the 'Abra de Bilbao' bay (N. Spain) were described in terms of biomass in order to record spatial changes on scales of a few km that reflect they prevalence ofExpand
