The application of unoccupied aerial systems (UAS) for monitoring intertidal oyster density and abundance

Remote Sensing in Ecology and Conservation
The eastern oyster (Crassostrea virginica) is a coastal foundation species currently under threat from anthropogenic activities both globally and in the Apalachicola Bay region of north Florida.

Range-Wide Genetic Population Structure and Environmental Adaptation in the Eastern Oyster (Crassostrea virginica) Provides Insight for Aquaculture. [PDF]

Mol Ecol
ABSTRACT Selective breeding in aquaculture is necessary to establish food security and meet demand for sustainably produced protein. An informed selective breeding program requires understanding how population structure, environmental adaptation, and human activities shape natural genetic variation in wild conspecifics.

The <i>Carpiodes</i> Conundrum: Molecular Hypothesis Testing Informs Conservation Applications for Carpsuckers (Catostomidae: <i>Carpiodes</i>) in Texas and Beyond. [PDF]

Ecol Evol
Our study investigates both distribution‐wide and within‐Texas genetic patterns of a group of fishes in need of greater taxonomic research (Catostomidae: Carpiodes). We recovered lineages of Carpiodes in the southeastern United States that are likely cryptic undescribed species and concurrently identify the native and taxonomic status of a uniquely ...

Phylogenetic and Environmental Insights Into the Biogeography of the Western Blacknose Dace, <i>Rhinichthys obtusus</i>. [PDF]

Ecol Evol
Pleistocene glaciations have shaped freshwater fish evolution and distribution patterns across North America. This study investigated the phylogeographical history of the Western Blacknose Dace (Rhinichthys obtusus) using mitochondrial genomic data, revealing three major clades that diverged 2–1.5 million years ago during Pleistocene glaciations when ...

Holocene evolution of Apalachicola Bay, Florida [PDF]

Fact Sheet, 2011
A program of geophysical mapping and vibracoring was conducted to better understand the geologic evolution of Apalachicola Bay. Analyses of the geophysical data and sediment cores along with age control provided by 34 AMS 14C dates on marine shells and wood reveal the following history.

Simulating synergistic impacts of climate change and human induced stressors on a northern Gulf of Mexico estuarine food web

Frontiers in Marine Science, 2023
Apalachicola Bay, an estuary located in northwest Florida, is likely to experience a continuing increase in the severity of the effects of changing climate and human-induced stressors, such as sea level rise and changes in freshwater inflow.

Coastal Wetland Soil Carbon Storage at Mangrove Range Limits in Apalachicola Bay, FL: Observations and Expectations

Frontiers in Forests and Global Change, 2022
Globally, mangrove range limits are expanding, often at the cost of adjacent coastal ecosystems including saltmarshes, potentially leading to a change in ecosystem services such as organic carbon (OC) sequestration.

Evidence for gene flow from the Gulf of Mexico to the Atlantic Ocean in bonnethead sharks (<i>Sphyrna tiburo</i>). [PDF]

Ecol Evol
Genomic data from bonnethead sharks reveals connectivity between the Gulf and Atlantic coasts of Florida, a zone that forms a genetic barrier for some larger shark species. Our demographic model also revealed rapid population growth and gene flow from the Gulf Coast to the Atlantic Coast, suggesting that sharks may migrate south for mating.

Validation of Oil Trajectory and Fate Modeling of the Deepwater Horizon Oil Spill

Frontiers in Marine Science, 2021
Trajectory and fate modeling of the oil released during the Deepwater Horizon blowout was performed for April to September of 2010 using a variety of input data sets, including combinations of seven hydrodynamic and four wind models, to determine the ...

The curious case of eastern oyster Crassostrea virginica stock status in Apalachicola Bay, Florida

Ecology and Society, 2015
The Apalachicola Bay, Florida, eastern oyster ( Crassostrea virginica ) industry has annually produced about 10% of the U.S. oyster harvest. Today’s simple individual-operator, hand-tonging, small-vessel fishery is remarkably similar to the one that ...
