Restoration of eastern oyster populations with positive density dependence [PDF]
Ecological Applications, 2017 Abstract Positive density dependence (i.e., Allee effects) can create a threshold of population states below which extinction of the population occurs. The existence of this threshold, which can often be a complex, multi‐dimensional surface, rather than a single point, is of particular importance in degraded ...

Drone lidar-derived surface complexity metrics as indicators of intertidal oyster reef condition
Ecological Indicators, 2023 Eastern oysters (Crassostrea virginica) generate structurally complex reef systems that offer diverse ecosystem services. However, there is limited understanding of how reef structure translates into reef condition.

Chitin Facilitated Mineralization in the Eastern Oyster [PDF]
Frontiers in Marine Science, 2018 Chitin is often reported in molluscan shells, where it likely contributes to the mechanical strength of the biomineral. However, the role of this polysaccharide in relation to the process of shell formation is not well understood. We investigated the deposition of chitin during shell repair in the Eastern oyster, Crassostrea virginica, by inserting ...

Use of natural trophic resources by Eastern oysters and Pacific oysters of different ploidy
Aquaculture and Fisheries, 2021 Ploidy manipulation, such as triploidy, in farmed oysters has been used as a tool to enhance oyster quality throughout all seasons because triploid oysters allocate less energy to gametogenesis, and therefore are deemed better performers than fertile diploids.

Metagenomic Assessment of the Eastern Oyster-Associated Microbiota
Genome Announcements, 2014 ABSTRACT Bacteria associated with the Eastern oysters ( Crassostrea virginica ) native to Apalachicola Bay, FL, were investigated using 16S rRNA gene amplicon metagenomic sequencing which revealed that the oyster microbiome was predominated by Cyanobacteria and ...

Frontiers in Aquaculture, 2023 Demand for oysters in the premium half-shell market drives the need for research to optimize and improve oyster aquaculture production methods. After setting, oysters are typically maintained in nursery upwellers that provide nutrients and oxygen while ...

Harmful Algae, 2021 Harmful algal bloom (HAB) dinoflagellate species Karlodinium veneficum and Prorocentrum cordatum (prev. P. minimum) are commonly found in Chesapeake Bay during the late spring and early summer months, coinciding with the spawning season of the eastern oyster (Crassostrea virginica).

Quantitative validation of a habitat suitability index for oyster restoration
Frontiers in Marine Science, 2016 Habitat suitability index (HSI) models provide spatially explicit information on the capacity of a given habitat to support a species of interest, and their prevalence has increased dramatically in recent years.

Spatial Dynamics of Two Host-Parasite Relationships on Intertidal Oyster Reefs
Diversity, 2021 Intertidal reefs comprised of the eastern oyster (Crassostrea virginica) have long experienced habitat loss, altering habitat patch characteristics of size and distance from edge to interior, potentially influencing spatial dynamics of host-parasite ...
