Energetic parameters of a population of Chlamys varia (Bivalvia: Pectinidae)

Interspecific comparison of Cd bioaccumulation in European Pectinidae (Chlamys varia and Pecten maximus)

Delineation of Pb contamination pathways in two Pectinidae: the variegated scallop Chlamys varia and the king scallop Pecten maximus.

Bioaccumulation of Pb was determined in Chlamys varia and Pecten maximus exposed to (210)Pb via seawater, food and sediment. Both scallops readily concentrated dissolved Pb with whole-body 7-d concentration factors of 250+/-40 and 170+/-70, respectively. In both species, more than 70% of Pb taken up from seawater was strongly retained within tissues (biological half-life>1.5 month) whereas Pb i...

Mitochondrial genome of the Peruvian scallop Argopecten purpuratus (Bivalvia: Pectinidae).

The mitochondrial genome of the Peruvian scallop Argopecten purpuratus was determined. The length of the mitochondrial coding region is 15,608 bp. A typical bivalve mitochondrial composition was detected with 12 protein-coding genes, 2 ribosomal RNA genes and 21 transfer RNA genes, with the absence of the atp8 gene. Fifty percent of the protein-coding genes use typical ATG start codon, whereas ...

A new species of Pecten (Mollusca: Bivalvia: Pectinidae) from northern Western Australia

Pecten dijkstrai n. sp. is described from several localities in northern Western Australia. It represents a new, rare example of a tropical member of the genus Pecten. The new species most closely resembles P. excavatus Anton, 1838, previously reported from southern Japan to Indonesia, differing in its smaller size, greater length (antero-posterior dimension), more numerous, lower radial costae...
