  2. Diazotroph Assemblages of Salt Marsh Plants Growing Along An Environmental Gradient: Assemblage Composition and Responses to Environmental Conditions

    <p>Many <em>Spartina alterniflora</em> dominated coastal salt marshes of the southeastern US are nitrogen-limited despite being among the most productive ecosystems known. Nitrogen fixation (diazotrophy) by the nitrogen-fixing microorganisms in these ecosystems is one of the primary sources of …

  3. Effects of shoreline development and freshwater discharge on nekton assemblage and trophic structure in a northern Gulf of Mexico estuary

    <p>Coastal salt marshes support a diversity of nekton and facilitate critical ecosystem functions but are threatened by shoreline development and climate change. Therefore, coastal ecosystem managers have begun incentivizing the use of living shorelines (LS), erosion control structures …

  5. Mycorrhizal Colonization of Native Salt Marsh Plants On Mississippi's Gulf Coast and the Effects of Commercial Mycorrhizal Inoculants On Nursery-Grown Plants

    <p>Salt marshes are important economically and ecologically to the Gulf Coast and other coasts worldwide. Due to human activities, many coastal salt marshes have been degraded or destroyed. Restoration efforts, through the replacement or addition of naturally occurring salt marsh plants, are taking …

    … modelling. In a place like Galveston Bay, Texas, coastal salt marshes and residential or urban centers coexisting near one another are commonplace, so tracking the health of the marsh based on anthropogenic actions, both conservational and detrimental, is key to preserving them. In turn, the …

  7. Locality of Topographic Ground Truth Data for Salt Marsh Lidar DEM Elevation Bias Mitigation Using Machine Learning

    … elevation models (DEMs) are crucial for modeling coastal salt marsh systems, simulating the coastal dynamics of sea level rise (SLR), and predicting storm surge inundation depth and duration. Improvements in lidar acquisition technology and data processing over the last decade have led to …
