Abstract:
... Black willow and eastern cottonwood are fast-growing hardwoods native to river bottoms throughout the southeastern United States, e.g., the Lower Mississippi Alluvial Valley (LMAV), that are often grown as short rotation woody crops (SRWCs) because of their potential to provide high biomass yields in short periods of time. This study focused on developing allometric equations to estimate individua ...
... Coastal wetlands are one of the most valuable ecosystems; however, they have an uncertain future when faced with increasing sea-level rise (SLR) and both human-induced and environmental stressors. To better understand future marsh resiliency, we examined above- and belowground biomass, carbon (C), nitrogen (N), and phosphorus (P) tissue content and sediment characteristics along a coastal elevatio ...
... The auxin‐mimicking herbicide quinclorac controls crabgrass (Digitaria spp.) after emergence in cool‐ and warm‐season turfgrass species. Quinclorac resistance has been confirmed in smooth [Digitaria ischaemum (Schreb.) Muhl.] and large crabgrass [Digitaria sanguinalis (L.) Scop.]. Two Mississippi smooth crabgrass populations have been confirmed as quinclorac‐resistant. Field experiments were condu ...
... Large rivers are highly important systems that require close monitoring of the ecological consequences of factors like commercial and recreational exploitation, channel alterations, and climate change. The Long‐Term Survey and Assessment of Large River Fishes in Illinois (LTEF) monitors the fish communities of the Illinois, Mississippi, Wabash, and Ohio rivers using daytime, pulsed‐DC electrofishi ...

Abstract:
... Worldwide, rivers provide important socio-economic and environmental functions and are essential to human well-being. The growing demand of user-functions and the change in river conditions due to large-scale morphology and climate change, increase the pressure on lowland river systems (e.g. Rhine, Meuse, Danube and Mississippi). To ensure a multi-functional river system, challenges related to unc ...
... AIM: Biogeography seeks to identify and explain the spatial distributions of species and has become an important tool used by conservationists to protect and manage aquatic organisms. Texas, located in the southwestern United States, is home to 52 species of freshwater mussels, 9 of which are endemic to Texas and 7 that are endemic to Texas and neighboring states or countries. There have been two ...
... The Macrhybopsis aestivalis complex (nine recognized species of small-bodied, riverine cyprinids) is predicted to have diversified allopatrically in response to prehistoric reorganizations of rivers tributary to the Gulf of México. To flesh out details of this hypothesis, we derived, from previous work, a mitochondrial (ND2) chronogram for interpretation against the background of a published nucle ...
... Scholarly work at the intersections of food and critical race studies has long articulated the historic and pervasive effects of racial hierarchy on the work and culture that surrounds food preparation. Drawing upon such work, this paper conducts a close reading of Anne Moody’s Coming of Age in Mississippi to demonstrate how the author describes a broader system of racial oppression through her ow ...

Abstract:
... The concentration of fine particulate matter (PM₂.₅) and the meteorological parameters were investigated at six monitoring stations across Mississippi, USA, from September 2013 to December 2014. The dataset was evaluated after dividing the locations into two groups based on city size: large (population larger than 45,000) and small (population less than 25,000). The daily mean concentration of PM₂ ...

Abstract:
... Evapotranspiration (ET) provides important information for hydrological studies, including estimating plant water requirements which can be derived from remote sensing data or simulated using hydrological models. In this study, ET derived from the Moderate Resolution Imaging Spectrometer (MODIS) was compared with ET simulated by the calibrated and validated Soil and Water Assessment Tool (SWAT) mo ...
... After being subject to several decades of degradation, the bottomland hardwood (BLH) forests within the Lower Mississippi Alluvial Valley have undergone landscape-scale restoration regimes through conservation easement programs, such as the Wetland Reserve Program (WRP). Reforested easements offer an opportunity for landowners' adoption of forest management practices to fulfill the program's long- ...

Abstract:
... Passiflora incarnata L., commonly known as maypop, is a wild passion fruit native to many areas of the eastern and southern United States where the climate ranges from subtropical to temperate. Although P. incarnata has had little attention paid to it for breeding purposes, it could be used in breeding for fruit production and possibly contribute cold hardiness genes in combination with other Pass ...
... Conservation agriculture has been marketed to producers as a sustainable way to increase soil productivity and buffer the effects of anticipated fluctuations in both climate and the price of fuel and fertilizer. Despite US Farm Bill financial incentives promoting the use of conservation practices such as no-tillage and cover crops among producers, widescale adoption of cover crops in the US remain ...

... Edwardsiella piscicida is a growing problem for catfish aquaculture in the southeastern United States, particularly in channel (Ictalurus punctatus) x blue (I. furcatus) catfish hybrids. Research has shown E. piscicida isolates recovered from farmed catfish in Mississippi form at least five discrete phyletic groups, with no apparent differences in virulence in channel and hybrid catfish. Laborator ...
... A new species of Bacciger Nicoll, 1914, is described from the digestive tract of the American gizzard shad, Dorosoma cepedianum (Lesueur), in some inland waterways of Mississippi, and in Mobile Bay, Alabama, U.S.A. This now represents the only nominal species in the genus from the northwest Atlantic Ocean or inland tributaries of eastern North America north of Mexico. Two potentially close relativ ...
... Chamaecrista fasciculata is a widely distributed, phenotypically variable species in the eastern U.S. Whereas studies have demonstrated genetic structure and local adaptation in northern areas of its distribution, there has been no comparison of genetic variability among populations at the southern extent where phenotypic variation is more complex. We characterized genetic variation at 14 microsat ...
... Numerous studies have evaluated the relationship between tree species diversity and productivity, with general trends suggesting a positive relationship. While most studies only use species richness, this study also analyzed how productivity changes with functional diversity and Shannon-Wiener's diversity index, to compare the impact of these different indicators of tree species diversity. This st ...

... Formerly common in tropical and subtropical waters of the Atlantic Ocean, the Critically Endangered smalltooth sawfish, Pristis pectinata, underwent severe declines over the past century, restricting population(s) to south and south‐west Florida in the US, and Bahamian waters. Anecdotal evidence (e.g. encounter reports from the public) suggests that P. pectinata have recently been observed in hist ...
... BACKGROUND: The timing of autumn migration in ducks is influenced by a range of environmental conditions that may elicit individual experiences and responses from individual birds, yet most studies have investigated relationships at the population level. We used data from individual satellite-tracked mallards (Anas platyrhynchos) to model the timing and environmental drivers of autumn migration mo ...
... Fossil fuels have been the major source of electricity supply in the United States of America (USA) for many decades. While a significant shift has occurred from coal-dominated supply to natural gas and renewable source based supplies in recent decades, there is still large potential to improve biomass supported electricity contribution in rural communities, which depend majorly on forest-related ...
