Lethal and sublethal effects of sediment burial on the eastern oyster Crassostrea virginica

Sublethal cellular effects of short-term raphidophyte and brevetoxin exposures on the eastern oyster Crassostrea virginica

The susceptibility of shellfish to raphidophyte toxicity is not well resolved. This study examined the sublethal cellular responses of eastern oysters Crassostrea virginica exposed to 2 raphidophyte blooms (Chattonella subsalsa or Fibrocapsa japonica). Also, based on the hypothesis that raphidophyte toxicity is related to brevetoxin production, we determined the cellular responses of oysters to...

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...

Predator effects on host−parasite interactions in the eastern oyster Crassostrea virginica

Both parasitism and predation may strongly influence population dynamics and community structure separately or synergistically. Predator species can influence host−parasite interactions, either by preferentially feeding on infected (or uninfected) hosts — and thus altering parasite prevalence patterns — or by affecting host behavior in ways that increase host susceptibility to parasites. In thi...

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...
