Use Of Livestock Risk Protection Insurance For Cattle Continues To Grow, Jay Parsons

Cornhusker Economics

When used as a regular part of a market risk management plan, livestock risk protection (LRP) insurance can help protect profits in years where markets turn for the worse. The recent changes to the program have made LRP insurance more appealing to cattle producers and sales of LRP have subsequently increased dramatically. Strong price increases may make LRP unnecessary, but it is difficult to predict when the price increases will end. LRP insurance is a safety net, reducing downside price risk by providing a floor on national price expectations while also allowing producers to take advantage of higher national prices …

Wetland Soil Development Along Salinity And Hydrogeomorphic Gradients In Active And Inactive Deltaic Basins Of Coastal Louisiana, Amanda Fontenot

LSU Master's Theses

Coastal wetlands provide an abundance of ecosystem services that benefit society, such as essential habitat for commercial species, storm protection, nutrient cycling, and carbon storage. Louisiana faces rapid rates of relative sea level rise (natural subsidence and eustatic sea levels) that threaten wetland survival, which are amplified by a reduction of riverine sediment input. An important determining factor of marsh survival is the formation of wetland platform elevation, known as vertical accretion, which is determined by several processes including sediment deposition & erosion, below ground biomass (BGB) productivity, decomposition of organic matter, shallow & deep subsidence, and soil compaction. Feldspar …

The Link Between Intracellular Calcium Signaling And The Nitric Oxide-Dependent Release Of Chloride In Retinal Amacrine Cells, Li Zhong

LSU Doctoral Dissertations

Regulation of cytosolic Cl^- is an important determinant in synaptic function. Our lab has discovered that cytosolic Cl^- is regulated not only by transport across the plasma membrane but that Cl^- can also be released from internal Cl^- stores (Hoffpauir et al., 2006) in amacrine cells (ACs). Nitric oxide (NO) is a small molecule neurotransmitter that has been demonstrated to be involved in cytosolic Ca²⁺ elevations and Cl^- regulation via activation of the cystic fibrosis transmembrane regulator (CFTR) (Krishnan et al., 2017). Here, I test the hypothesis that intracellular Ca²⁺ signaling mediates the …
