Condizione ecologica di Ruditapes decussatus (Veneridae) e sua presenza in aree di raccolta nel Golfo di Olbia = Ecological status and occurrence of Ruditapes decussatus (Veneridae) in harvested sites within the Gulf of Olbia [PDF]

open access: yes, 2010
A pilot study was performed in order to evaluate the ecological status of the clam Ruditapes decussatus and its occurrence in specific harvested areas within the Gulf of Olbia. Indeed, since 1998, stocks of this clam seems to be decreased, due to intense

In situ potential use of metallothionein as a biomarker of cadmium contamination in Ruditapes decussatus

open access: yesEcotoxicology and Environmental Safety, 2009
Cadmium (Cd) and metallothionein (MT) concentrations were analysed in the gills and digestive gland of clams Ruditapes decussatus collected from two sites of the Gulf of Gabès (Tunisia) which differ by their degree of pollution. The effect of biotic (maturity stages, protein, sex and body mass) and abiotic factors (temperature, salinity, site and ...

Cloning and characterization of cDNA probes for the analysis of metallothionein gene expression in the Mediterranean bivalves: Ruditapes decussatus and Cerastoderma glaucum

open access: yes, 2009
International audiencecDNA probes have been developed for subsequent use in monitoring the cadmium exposure of the clam Ruditapes decussatus and the cockle Cerastoderma glaucum using metallothionein (MT) gene expression in different tissues of these ...

Polycyclic aromatic hydrocarbons concentrations and biomarker responses in the clam Ruditapes decussatus transplanted in the Ria Formosa lagoon

open access: yes, 2009
Clams Ruditapes decussatus were transplanted in the Ria Formosa lagoon and the variation of PAH concentrations in the whole soft tissues measured, along with a suite of biomarkers, including the following: (a) phase I and phase II metabolism of ...

Physiological responses and scope for growth of Ruditapes decussatus from Ria Formosa, southern Portugal, exposed to increased ambient ammonia

open access: yesScientia Marina, 2004
In this study we investigate the effects of exposure to increased ambient ammonia-N concentrations as a cause of decreased scope for growth and mortality of R.decussatus during the summer months in Ria Formosa, southern Portugal.

Physiological Plasticity of Ruditapes decussatus in Response to Short-Term Changes in Substrate Availability

open access: yesFishes
Substrate availability is a key environmental factor for burrowing bivalves, yet its physiological importance in adult clams remains poorly understood.

Routes of TBT uptake in the clam Ruditapes decussatus. II. Food as vector of TBT uptake

open access: yes, 2002
Marine bivalves are exposed to contaminants via the aqueous phase, sediments and food. Nevertheless, the relative importance of these phases as uptake vectors of contaminants in these marine organisms has not been well studied.
