Bacterias en la hemolinfa de Argopecten purpuratus (Lamark, 1819) (Bivalvia: Pectinidae) [PDF]

Revista de biología marina y oceanografía, 2002
Twenty three strains of bacteria were isolated from the hemolymph of Argopecten purpuratus. Our results point out to the predominance of asporogenous Gram-negative rods. We suggest that the presence of these bacteria in the hemolymph is a natural phenomenon.

Characterization of the immune response of the north scallop Argopecten purpuratus (Lamarck, 1819) (Mollusca: Bivalvia)

Ciencias Marinas, 2002
The immune response in mollusks has an important role as a defense against bacteriae, fungi, protozoa and metazoans. The hemocytes are responsible for generating different kinds of innate responses such as: phagocytosis, encapsulation and production of ...

Size matters: Physiological sensitivity of the scallop Argopecten purpuratus to seasonal cooling and deoxygenation upwelling-driven events

Frontiers in Marine Science, 2022
Environment imposes physiological constraints which are life-stage specific as growth-maintenance and/or growth-reproduction energetic requirements are size and volume-dependent.

Genomic characterization of interspecific hybrids between the scallops Argopecten purpuratus and A. irradians irradians. [PDF]

PLoS One, 2013
The Peruvian scallop (Argopecten purpuratus) has been introduced to China and has successfully been hybridized with the bay scallop (A. irradians irradians). The F1 hybrids of these two scallops exhibited a large increase in production traits and some other interesting new characteristics. To understand the genetic basis of this heterosis, nuclear gene

Population biology of the sea star Anasterias minuta (Forcipulatida: Asteriidae) threatened by anthropogenic activities in rocky intertidal shores of San Matías Gulf, Patagonia, Argentina [PDF]

, 2017
In Patagonian coastal areas, intertidal benthic communities are exposed to extreme physical conditions. The interaction between harsh environment and anthropogenic pressure can generate changes in population biology of marine invertebrates, like density ...

BIOINCRUSTANTES EN ESTRUCTURAS DE CULTIVO DE Argopecten purpuratus EN BAHÍA SAMANCO, PERÚ

Ecología Aplicada, 2016
Los bioincrustantes, son organismos que se adhieren sobre estructuras duras que se sumergen o estan en contacto continuo con el agua de mar. Con el objetivo de dar a conocer la composicion de especies bioincrustantes en el cultivo suspendido de Argopecten purpuratus, el dia 20 de Octubre de 1998 se realizo un muestreo de diferentes materiales y sobre ...

Latitudinal variation in the reproductive cycle of two bivalves with contrasting biogeographical origin along the Humboldt Current Upwelling Ecosystem

Scientia Marina, 2012
Argopecten purpuratus (Lamarck, 1819) and Mesodesma donacium (Lamarck, 1818) are bivalves that inhabit the Humboldt Current Upwelling Ecosystem. They have contrasting biogeographical origins, suggesting that their responses to exogenous factors should ...

Potential roles of MEK1 on aging in Argopecten scallops

Frontiers in Marine Science, 2022
Dual specificity mitogen-activated protein kinase kinase 1 (MEK1) has been found to regulate aging through the Ras/Raf/MEK/ERK cascade in terrestrial animals. However, few reports have focused on MEK1 promoting aging in marine bivalves. In this study, we

CRECIMIENTO COMPARATIVO DE LA CONCHA DE ABANICO (Argopecten purpuratus ) EN SISTEMAS SUSPENDIDOS

Ecología Aplicada, 2008
Con el objetivo de determinar diferencias en el crecimiento de la concha de abanico  Argopecten purpuratus procedentes de diferentes lugares, se realizaron dos experimentos de cultivo comparativo en sistemas suspendidos, tales como “pearl-nets” y linternas.
