Filter feeding by oysters reduces disease transmission in a marine host–parasite system

Ecology, Volume 107, Issue 1, January 2026.
Abstract As a mechanism of the dilution effect, predation and filter feeding on parasitic propagules are hypothesized to reduce transmission to susceptible hosts and alter host–parasite interactions. In marine systems, the effect of other community members on the disease dynamics of microparasites in their suitable hosts is poorly known.

Assessment of recent eastern oyster (Crassostrea virginica) reef restoration projects in the Great Bay Estuary, New Hampshire: Planning for the future [PDF]

, 2016
Current oyster populations in New Hampshire total less than 10% of what they were in the 1980s, and the causal factors for the declines include disease, sedimentation, and human harvest.

High‐Resolution Metabarcoding Reveals the Microbiome Dynamics of Mangrove Oysters (Crassostrea gasar) and Their Habitat

Marine Ecology, Volume 47, Issue 1, January/February 2026.
ABSTRACT The mangrove oyster (Crassostrea gasar) plays a key ecological role in Amazonian estuaries by filtering suspended organic particles, microalgae, phytoplankton, and bacteria, contributing to water quality and nutrient cycling. Its gut microbiota is shaped by complex interactions with the surrounding aquatic environment, reflecting the ...

Cultured eastern oysters (Crassostrea virginica): retention and assimilation of picophytoplankton using a multi-biomarker approach

Aquatic Living Resources, 2017
In this study, we investigated the food sources of eastern oysters Crassostrea virginica cultivated in Atlantic Canada. Stable isotopes (13C and 15N) and fatty acid biomarkers were used to identify these sources under in situ conditions for suspended (∼0.

Evaluating the Growth and Survival of Diploid and Triploid Blue Mussel (Mytilus edulis) Larvae From Different Sources Reared at Constant and Fluctuating Thermal Regimes

Aquaculture Research, Volume 2026, Issue 1, 2026.
Farming triploid bivalves has gained favor due to their enhanced growth rate and effective sterility; however, they may exhibit lower thermal tolerance, a concern due to climate change. Environmental conditions influence ectotherm performance, resulting in natural intraspecific variation across geographic regions through local adaptation, developmental

Alkaloids Isolated From the Gastropod Reishia clavigera: Their Antibacterial and Cytotoxic Activities

Journal of Chemistry, Volume 2026, Issue 1, 2026.
Reishia clavigera, an edible marine gastropod consumed in Asia and used in traditional medicine, was investigated for its secondary metabolite content. Despite its widespread consumption and ethnomedicinal use, no comprehensive study has examined the secondary metabolites from whole‐body extracts.
