Impacts of Deepwater Horizon oil and associated dispersant on early development of the Eastern oyster Crassostrea virginica

Impacts of Deepwater Horizon oil and associated dispersant on early development of the Eastern oyster Crassostrea virginica.

The explosion of the Deepwater Horizon (DWH) oil platform resulted in large amounts of crude oil and dispersant Corexit 9500A® released into the Gulf of Mexico and coincided with the spawning season of the oyster, Crassostrea virginica. The effects of exposing gametes and embryos of C. virginica to dispersant alone (Corexit), mechanically (HEWAF) and chemically dispersed (CEWAF) DWH oil were ev...

Status of the Eastern Oyster (Crassostrea virginica): March 2007

Genetic linkage map of the eastern oyster Crassostrea virginica Gmelin.

Amplified fragment length polymorphisms (AFLPs), along with some microsatellite and Type I markers, were used for linkage analysis in Crassostrea virginica Gmelin, the eastern oyster. Seventeen AFLP primer combinations were selected for linkage analysis with two parents and their 81 progeny. The 17 primer combinations produced 396 polymorphic markers, and 282 of them were segregating in the two...

Shell hardness and compressive strength of the Eastern oyster, Crassostrea virginica, and the Asian oyster, Crassostrea ariakensis.

The valves of oysters act as a physical barrier between tissues and the external environment, thereby protecting the oyster from environmental stress and predation. To better understand differences in shell properties and predation susceptibilities of two physiologically and morphologically similar oysters, Crassostrea virginica and Crassostrea ariakensis, we quantified and compared two mechani...

Modeling the MSX Parasite in Eastern Oyster (Crassostrea virginica) Populations. I. Model Development, Implementation, and Verification

A mathematical model simulating tile hos1-parasi1e-envi ronmentaJ imeractions of eas1em oys1ers (Cra.tsos1rea ,,irginica) and the pathogen, Haplo,poridi1111111elso11i. which cause~ MSX disease, has been deve loped. The model ha~ 1 components. One replica1es the infec1ion process within the oys1er and 1he other si1nulaies transmis,ion. The infection-development co1nponcnt re lies on basic physio...
