Genetic background effects contribute to the phenotypic consequences of mutations, and are pervasive across all domains of life that have been examined, yet little is known about how they modify genetic systems. In part this is due to the lack of tractable model systems that have been explicitly developed to study the genetic and evolutionary consequences of background effects. In this study we...

This paper describes, for the first time, that scallops can be attracted into static fishing gear using LED lights. novel finding presents an opportunity development of a new, low impact method scallops. Traditionally, wild caught are primarily fished dredges and trawls. Due to their penetrative nature, interaction this towed with seabed cause significant damage sensitive marine habitats specie...

The unique, double-retina, concave mirror eyes of scallops are abundant along the valve mantle margins. Scallops have the most acute vision among the bivalve molluscs, but little is known about how eyes vary between scallop species. We examined eye morphology by immunofluorescent labeling and confocal microscopy and calculated optical resolution and sensitivity for the swimming scallops Amusium...

Calmodulin has been isolated and characterized from the gill of the bay scallop aequipecten irradians. Quantitative electrophoretic analysis of epithelial cell fractions show most of the calmodulin to be localized in the cilia, specifically in the detergent- solubilized membrane-matrix fraction. Calmodulin represents 2.2 +/- 0.3 percent of the membrane-matrix protein or 0.41 +/- 0.5 percent of ...

Great scallop (Pecten maximus) is a bivalve species belonging to the Pectinidae family that deeply linked well-known network of pilgrimages in Spain (The Way Saint James), becoming gourmet product Galician cuisine. The goal this study was fill gaps currently exist specific inventory dedicated capture and processing great scallop, as well assess environmental burdens derived from system. constru...

Arcobacter sp. strain LFT 1.7 was isolated from great scallop (Pecten maximus) larvae. Analysis of the 16S rRNA gene sequence showed that strain LFT 1.7 formed an independent lineage in the genus Arcobacter The draft genome of LFT 1.7 was sequenced to determine the taxonomic position and ecological function of this strain.

18 propellers is investigated, using the cusp (scallop) height as the objective function. This technique allow one to end mill a surface, while the tool is not necessarily oriented along the surface normal, stressing the need for better techniques to solve the accessibility problem in 5-axis modes.

We report here the 5.167-Mbp draft genome sequence of Vibrio VPAP30, isolated from an Argopecten purpuratus larval culture. Vibrio VPAP30 is the etiological agent of a vibriosis outbreak causing a complete collapse of a larval culture of the scallop A. purpuratus, which occurred in a commercial hatchery in Chile.

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 ...

We conducted a 5-month experiment at Turpialito in the Golfo de Cariaco, Venezuela, to examine whether the previously reported more rapid growth of scallop Euvola ziczac in bottom compared to suspended culture can be attributed to more abundant or higher quality food resources near the sediment/water interface. The various body components (shell, muscle, digestive gland, gonad and remaining tis...
