Long-term assessments are critical to determining persistence and shoreline protection from oyster reef nature-based coastal defenses Long-term assessments are critical to determining persistence and shoreline protection from oyster reef nature-based coastal defenses
Nature-based coastal defense using bivalve reefs provides a potentially self-sustaining approach for regions facing high coastal land loss, relative sea level rise and increasing frequency and intensity of storms. Success of such nature-based coastal defense depends on the reef-building species' life history, habitat requirements, and ability to thrive through short-term and longer-term

Local populations of eastern oyster from Louisiana differ in low salinity tolerance Local populations of eastern oyster from Louisiana differ in low salinity tolerance
Eastern oysters Crassostrea virginica support a critical commercial industry and provide many ecosystem services to coastal estuaries yet are currently threatened by changing estuarine conditions. A changing climate and the effects of river and coastal management are altering freshwater inflows into productive oyster areas, causing more frequent and extreme salinity exposure. Although...

Defining oyster resource zones across coastal Louisiana for restoration and aquaculture Defining oyster resource zones across coastal Louisiana for restoration and aquaculture
Eastern oysters (Crassostrea virginica) are a critical ecological and commercial resource in the northern Gulf of Mexico facing changing environmental conditions from river management and climate change. In Louisiana, USA, development of restored reefs, and off-bottom aquaculture would benefit from the identification of locations supportive of sustainable oyster populations (i.e...

Nekton community dynamics within active and inactive deltas in a major river estuary: Potential implications for altered hydrology regimes Nekton community dynamics within active and inactive deltas in a major river estuary: Potential implications for altered hydrology regimes
High fisheries production within estuaries is associated with coastal upwelling, tidal mixing, and land-based runoff facing increasing impacts from climate and human activities. Active river deltas receive large riverine inflows compared to inactive river deltas, providing contrasting estuaries to compare impacts of river inflow on estuarine nekton. We quantified nekton assemblages and...

Five years of monitoring a bio-engineered living shoreline: Comparison of oyster population development by reef technology. Five years of monitoring a bio-engineered living shoreline: Comparison of oyster population development by reef technology.
The Living Shoreline Demonstration Project (PO-148) used five bio-engineered reef technologies (Reef Balls in two configurations; Figure 1) acting as breakwaters to protect vulnerable shorelines. While the primary goal is to attenuate wave energy, the sustainability and success of these products as “living” shorelines are based on their ability to enhance oyster habitat, enabling the...

Effects of sample gear on estuarine nekton assemblage assessments and food web model simulations Effects of sample gear on estuarine nekton assemblage assessments and food web model simulations
Long-term fisheries-independent sampling data inform population status and trends of species-specific biomass and are often used to drive biomass-based food web models such as the Comprehensive Aquatic Systems Model (CASM). Indicators such as total biomass and mean trophic level derived from these data and from CASM outputs inform management and facilitate assessments of on-going and...
