Changes In Wetland Soil Processes And Ecosystem Functions Six Years After Marsh Creation In Barataria Bay, Louisiana, Erol R. Knaus
Changes In Wetland Soil Processes And Ecosystem Functions Six Years After Marsh Creation In Barataria Bay, Louisiana, Erol R. Knaus
LSU Master's Theses
Louisiana contains about 40% of the conterminous United States coastal and estuarine wetlands but also has the highest rates of wetland loss at around 80% of the total. Approximately 4,900 km2 of coastal land in Louisiana has been lost since 1930. Our study location, Barataria Bay, has one of the highest coastal wetland erosion rates in the nation, at ∼41 km2 per year; and therefore, is a high priority for wetland restoration activities. In 2014, sandy sediment dredged from the bed of the Mississippi River was placed in Barataria Bay as part of a restoration effort. Samples were …
Chronic Toxicity Of Nano Metallics On Red Swamp Crayfish (Procambarus Clarkii) In Laboratory And Mesocosm Studies, Jake Andrew Farlow
Chronic Toxicity Of Nano Metallics On Red Swamp Crayfish (Procambarus Clarkii) In Laboratory And Mesocosm Studies, Jake Andrew Farlow
LSU Master's Theses
Nanotechnology has become integrated in commercial, industrial and medical products, and its use has grown exponentially in the past several years. Although potential applications of nanoparticles (NPs) are numerous, concerns about their water quality, environmental, and human health impacts remain unclear. Crayfish are ubiquitous to streams and wetland habitats, are used as a food source, and inhabit areas that could be impacted by water quality issues. Numerous studies have been conducted on the toxicity of various classes of agricultural pesticides and oils to crayfish (Procambarus clarkii) as a non-target organism. However, there is little evidence published on chronic toxicity of …

Juvenile Crawfish (Procambarus Clarkii) Lc50 Mortality From South Louisiana Crude, Peanut And Mineral Oil, Okey Umejuru
LSU Master's Theses
Nearly every continent has species of crawfish that inhabit wetlands or are near coastal areas where petroleum and other oils are produced, transported, and accidentally released. Most crawfish cannot tolerate polluted water. Thus, they could serve as biomonitors of fossil fuel, biofuel, and other oil releases and assess potential negative impacts such oils have on wetland and coastal ecosystems. The objectives of this study were to estimate the acute toxicity of three oils to juvenile crawfish and determine if toxicity was due to poisoning or interference with oxygen transfer across the gills. Juvenile crawfish (Procambarus clarkii) were tested for acute …
