Increasing duration of heatwaves poses a threat to oyster sustainability in the Gulf of Mexico

Ecological Indicators
The future of the wild oyster fishery in the northern Gulf of Mexico is largely uncertain due to changing environmental conditions and declining abundance of harvestable oysters.

Projected changes in mangrove distribution and vegetation structure under climate change in the southeastern United States

Journal of Biogeography, Volume 51, Issue 11, Page 2285-2297, November 2024.
Abstract Aim The climate change‐induced transition from grass‐dominated marshes to woody‐plant‐dominated mangrove forests has the potential to impact the ecosystem goods and services provided by coastal wetlands. To better anticipate and prepare for these impacts, there is a need to advance understanding of future changes in mangrove distribution and ...

Understanding species limits through the formation of phylogeographic lineages

Ecology and Evolution, Volume 14, Issue 10, October 2024.
We present a set of tests to examine processes of speciation that will help delimit taxa given deep phylogeographic history and interaction within hybrid zones. Outcomes from distinct phylogeographic pairs of snakes in North America all have the signature of divergence before or near the mid‐Pleistocene often with low migration.

Changes in the spectrum and rates of extracellular enzyme activities in seawater following aggregate formation [PDF]

Biogeosciences, 2010
Marine snow aggregates are heavily colonized by heterotrophic microorganisms that express high levels of hydrolytic activities, making aggregates hotspots for carbon remineralization in the ocean.

Dissolved organic nitrogen and nitrate in Apalachicola Bay, Florida: spatial distributions and monthly budgets [PDF]

Marine Ecology Progress Series, 2001
Despite the quantitative importance of dissolved organic nitrogen (DON) in aquatic sys- tems, information on the spatial and temporal distribution of DON in estuaries is lacking. We employed a combination of property-surface plots, hydrodynamic model results, and property-salin- ity plots to examine nitrate and DON distributions in Apalachicola Bay ...

Fitting metabolic models to dissolved oxygen data: The estuarine Bayesian single‐station estimation method

Limnology and Oceanography: Methods, Volume 22, Issue 8, Page 590-607, August 2024.
Abstract Continuous measurements of dissolved oxygen (DO) are useful for quantifying ecosystem metabolism, which is critical for understanding estuarine biogeochemistry and ecology, but current methods applied to these data may lead to estimates that are physically impossible and poorly constrained errors. Here, we present a new approach for estimating

Contrasting stocks and origins of particulate and mineral-associated soil organic carbon in a mangrove-salt marsh ecotone

Geoderma
The global warming-driven poleward expansion of mangrove habitats (e.g., Avicennia germinans and Rhizophora mangle) into temperate salt marshes (e.g., Spartina alterniflora and Juncus roemerianus) has been shown to alter coastal soil organic carbon (SOC)

The use of conceptual ecological models to identify critical data and uncertainties to support numerical modeling: The northern Gulf of Mexico eastern oyster Crassostrea virginica example

Marine and Coastal Fisheries, Volume 16, Issue 4, August 2024.
Abstract Objective Increasing reliance on numerical simulation models to help inform management and restoration choices benefits from careful consideration of critical early steps in model development. Along the northern coast of the Gulf of Mexico, the eastern oyster Crassostrea virginica fulfills important ecological and economic roles.

The Role of Advection in Storm Surge for Hurricane Michael (2018)

Journal of Geophysical Research: Oceans, Volume 129, Issue 7, July 2024.
Abstract Hurricane Michael (2018) made landfall near Mexico Beach, FL, as a Category 5 hurricane, with gauge‐measured water levels over 4 m. Wind and pressure fields were created by blending a parametric near‐field model with a gridded far‐field model. Winds and modeled water levels were well validated across Michael's large impact a‐ea.

Remote sensing analysis of rainstorm effects on sediment concentrations in Apalachicola Bay, USA

Ecological Informatics, 2011
Abstract Remote sensing of total suspended solids (TSS) by satellite techniques in estuaries and bays plays an important role in monitoring water quality over a large area. It is valuable to the management of coastal water environment and ecosystems.
