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.

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 ...

Oyster hatchery breakthrough of two HABs and potential effects on larval eastern oysters (Crassostrea virginica)

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).

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 ...

Fluxomics of the Eastern Oyster for Environmental Stress Studies [PDF]

Metabolites, 2014
The metabolism of 2-13C/15N-glycine and U-13C-glucose was determined in four tissue blocks (adductor muscle, stomach and digestive gland, mantle, and gills) of the Eastern oyster (Crassostrea virginica) using proton (1H) and carbon-13 (13C) nuclear magnetic resonance (NMR) spectroscopy. The oysters were treated in aerated seawater with three treatments

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.

SURVIVAL OF TOXOPLASMA GONDII OOCYSTS IN EASTERN OYSTERS (CRASSOSTREA VIRGINICA) [PDF]

Journal of Parasitology, 2004
Toxoplasma gondii has recently been recognized to be widely prevalent in the marine environment. It has previously been determined that Eastern oysters (Crassostrea virginica) can remove sporulated T. gondii oocysts from seawater and that oocysts retain their infectivity for mice. This study examined the long-term survival of T.

Overcoming restoration paradigms: value of the historical record and metapopulation dynamics in native oyster restoration

Frontiers in Marine Science, 2015
Restoration strategies for native oyster populations rely on multiple sources of information, which often conflict due to time- and space-varying patterns in abundance and distribution.

Nursery upweller type has minimal impact on subsequent grow-out of Eastern oysters (Crassostrea virginica)

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 ...

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.
