Some properties of habituation of siphon withdrawal in the slimy clam (Ruditapes decussatus)
Abstract Over the last decades the comparative study of the intelligence of invertebrate animals has shown the psychological complexity of these species. Although significant research has been carried out on the phyla of mollusks in gastropods and cephalopods, there has been little research concerning bivalves.

Recruitment of the clam Ruditapes decussatus in the Lagoon of Thau, mediterranean
The spatial and temporal patterns of recruitment of juvenile clams Ruditapes decussatus were investigated in the Mediterranean lagoon of Thau. The periods of release of clam larvae were determined by monitoring the gonad maturity index in samples of adult females. Two massive spawnings were detected. Recruitment, deduced from spat density, was abundant

Heterozygote deficiency and population structure in the bivalve Ruditapes decussatus [PDF]
The genetic structure of the bivalve Ruditapes decussatus from a Mediterranean lagoon was investigated at seven enzymatic loci. Samples of adults collected at the same period in different localities were genetically homogeneous. Slight allele frequency differences were observed between two annual cohorts of spat.

Ruditapes decussatus (Linnaeus, 1758) (Veneridae) is an Atlanto-Mediterranean bivalve whose populations have experienced reductions and, in some instances, hybridisation with allochthonous R. philippinarum.

The spatial and seasonal variation of total and subcellular distribution of Cd, Cu, and Zn was followed in different tissues (gills, digestive gland, and remaining tissues) of the clam Ruditapes decussatus collected along a metal contamination gradient in the Ria Formosa lagoon (southern Portugal) and compared with metallothionein (MT) concentrations ...

Hermaphroditism in Ruditapes decussatus (L.) (Bivalvia) from the Galician coast (Spain)
Inmature individuals of Ruditapes decussatus, collected from the Galician coast (Spain), were maintained in a laboratory open-flow seawater system over a 76-day period at a temperature of 18-20ºC and fed with Isochrysis galbana clone T-ISO.

Involvement of Metallothionein in Zn Accumulation and Elimination Strategies in Ruditapes decussatus
The aim of this study was to identify the involvement of metallothionein (MT) in Zn accumulation and elimination strategies in different tissues (gills, digestive gland, and remaining tissues) of Ruditapes decussatus. Clams were exposed to two Zn concentrations (100 and 1000 microg/L) for 40 days, followed by a depuration period of 50 days.

In the 80ies, in Southern Europe and in particular in Ria Formosa there was an episode of heavy mortality of the economically relevant clam Ruditapes (R.) decussatus associated with a debilitating disease (Perkinsosis) caused by Perkinsus olseni.
