A Change in Fish Assemblages in the Pascagoula River, MS
<p>The Pascagoula River in southeastern Mississippi is the largest remaining un-impounded river system in the contiguous United States and have seen a change in fish assemblages over time. Examination of long-term fish assemblage data show that the mainstem Pascagoula River and its two major …

Juvenile and subadult Gulf Sturgeon (Acipenser desotoi) use of the Pascagoula River estuary
… the northern Gulf of Mexico including coastal rivers, estuaries, and marine waters, making annual migrations between freshwater and marine habitats for spawning/summer resting and feeding, respectively. Since past studies prioritize adult movement, understanding how and when juvenile and …

Historical Channel Adjustments in the Pascagoula River Basin and Adjacent Systems, Southeast Mississippi
… historical cross-section adjustments in 13 rivers of the Pascagoula Basin and adjacent fluvial systems over the last 30-50 years, which could reveal hydrologic and sedimentary responses to natural causes such as flooding or various anthropogenic activities in the region, such as logging, …

Geomorphic Assessment and Flow Modeling of Pearl Darter (Percina aurora) Habitat in the Pascagoula River Watershed
… threatened species that only resides in the Pascagoula River watershed. Despite its status, habitat preference remains unclear. To fill this knowledge gap, I developed a novel approach to summarizing morphological characteristics of over 500 sandbars across 3 tributaries and mainstem of the …

Gulf Sturgeon of the Pascagoula River: Post-Katrina Assessment of Seasonal Usage of the Lower Estuary
<p>The Pascagoula watershed likely offers the greatest possibility for the survival of the Gulf sturgeon, <em>Acipenser oxyrinchus desotoi</em> within Mississippi. The focus of this project was to determine the routes Gulf sturgeon take through the lower Pascagoula River which splits at river …

Population Parameter Estimation and Stable Isotope Analysis of Gulf Sturgeon (Acipenser oxyrinchus desotoi) in the Pascagoula River
… Gulf of Mexico. Their range is from the Pearl River, LA, in the west to the Suwannee River, FL, in the east with a longitudinal divide at Mobile Bay, AL, creating a western population unit (WPU) and an eastern population unit (EPU). Sturgeon belonging to the WPU exhibit lower abundances, higher …

Detecting Coastal Marsh Change from Aerial Imagery using Spectral and Textural Methods: Pascagoula River Estuary, Mississippi, 1955-2014
… extent of intertidal marsh at the mouth of the Pascagoula River in Jackson County, Mississippi to determine whether marsh extent changed during the period 1955-2014 and to ascertain rates of change. Marsh extent was mapped at 3 meters GSD using spectral and textural aerial image data for image …

Spatial and Seasonal Patterns of Above- and Belowground Vegetation Biomass and Potential Drivers in the Pascagoula River Delta, MS
… called a marsh organ. The West Channel of the Pascagoula River contained significantly higher belowground biomass than the East Channel, which is more anthropogenically modified. Vertical distribution of belowground biomass did not strongly vary between seasons or channels. Elevation was …

Habitat use of Gulf Sturgeon (Acipenser oxyrinchus desotoi) in Pascagoula River holding areas and in estuarine and marine environments including Ship Island, Mississippi and Mobile Bay, Alabama
… anadromous species that inhabit coastal rivers in the northern Gulf of Mexico and make annual migrations between riverine and marine habitats. They are divided into western or an eastern river systems based on the location of their natal river relative to Mobile Bay. Tracking of GS …

Spatial Ecology and Movement Patterns of Black Drum (Pogonias cromis) and Sheepshead (Archosargus probatocephalus) in Mississippi Sound
… spawning migrations. Black Drum tagged in Pascagoula River Estuary exhibited broader movements and higher inter-subsystem transition frequencies compared to St. Louis Bay-tagged individuals, highlighting spatial variability in connectivity. Network analyses identified Pascagoula River …

Sub-Pixel Classification of Historical and Current Marsh Habitat For the Eastern Mississippi Gulf Coast Using Remotely Sensed Images
… years (1984-2011) for the Western Lower Pascagoula River Basin. The other main objective was to complete an analysis of how the estuarine emergent marsh has changed during this historical time series. Landsat (medium resolution) and Quickbird (high resolution) imagery will be utilized to …

An Assessment of the Diverse Freshwater Turtle Fauna of Mississippi
… through a statewide investigation of all major river drainages of the state. Using baited hoop nets (90 cm and 120 cm diameter), turtles were collected, identified to species and sex, and measured, before being released. Turtle assemblages were assessed in both lotic and lentic environments from …

Upland Migration of Coastal Marshes as a Response to Sea Level Rise and Fire Management: Past, Present, and Predicted
… Bay National Estuarine Research Reserve and the Pascagoula River delta over two-time intervals since 1955 and focused on the forest-marsh dynamics. I found that while there were areas of forest transitioning to marsh and the rates of these transitions increased from the first-time interval to the …

The Ecology and Evolution of the Freshwater Turtles of Southern Mississippi
… These data were then used to determine if riverine habitat and surrounding land cover has any effect on turtle communities. Similarly, a state-wide population genetic study on the Spiny Softshell turtle (<em>Apalone spinifera) </em>was initiated.</p> <p>The surveys performed for this study …
