The banded carpet shell Polititapes rhomboides is a fishery resource and suitable candidate for the development of native clam aquaculture in Europe. Here, we analyzed nine microsatellite loci wild samples to provide estimates genetic diversity population differentiation NW Spain, main production area this clam. We also wild-caught broodstock hatchery-reared seed investigate consequences stock ...

Doubly Uniparental Inheritance (DUI) is one of the most striking exceptions to the common rule of standard maternal inheritance of metazoan mitochondria. In DUI, two mitochondrial genomes are present, showing different transmission routes, one through eggs (F-type) and the other through sperm (M-type). In this paper, we report results from a multiplex real-time quantitative polymerase chain rea...

The striped venus clams Chamelea gallina and C. striatula are commercially important bivalves inhabiting European and North African coastal waters. The taxonomic status of these taxa has been the subject of debate for decades. In order to elucidate this issue, we generated 5S and 28S ribosomal RNA and H3 histone gene probes and mapped them by fluorescent in situ hybridization to the chromosomes...

The aim of this study was to characterize the reproductive cycle of Anomalocardia brasiliana, typical of the estuarine region of the Cachoeira River, Ilhéus, Bahia, Brazil. For this purpose, 20 specimens were collected biweekly between August 2005 and August 2006 on an intertidal bank (14º 48' 23" S and 39º 02' 47" W). The animals were measured on the anteroposterior axis (length), examined mac...
