An Analysis Of Risk Perceptions And Attitudes Towards Climate Change Among Residents Of Southeastern Louisiana, Heather Marie Brown
An Analysis Of Risk Perceptions And Attitudes Towards Climate Change Among Residents Of Southeastern Louisiana, Heather Marie Brown
LSU Master's Theses
Climate change is an important issue of concern, as its environmental impacts are already beginning to manifest in various means, such as through sea level rise and increased frequencies of storms. Areas of high vulnerability to the effects of climate change, such as southeastern Louisiana, are prime locations to initiate research in determining what factors influence individual’s risk perceptions towards climate change. This study aims is to identify key factors, specifically in the areas of socioeconomic, demographic, exposure, and attitudinal attributes, which affect climate change risk perceptions. The study area is that of the zip codes around Lake Pontchartrain in …
Metacommunity Dynamics And The Biogeography Of Central Louisiana Crayfishes, William Robert Budnick
Metacommunity Dynamics And The Biogeography Of Central Louisiana Crayfishes, William Robert Budnick
LSU Master's Theses
The greatest diversity of crayfishes, especially of rare Orconectes species, is found in the central Louisiana watersheds (Red River, Mermentau, Calcasieu, and Vermillion-Teche), and most species are widely distributed among the drainages. The purpose of this research was to lay groundwork for species distribution and metacommunity modelling for crayfishes in this region. To address this goal, two field studies were performed in the summers of 2013 and 2014, as well as an indoor laboratory study. Analyses of broadly distributed species indicated no significant correlations between species abundances and habitat variables nor any significant environmental gradients for those species. Within-drainage variability …
Population Abundance And Transience Of Selected Coastal Plain Crayfishes, Samantha Lott
Population Abundance And Transience Of Selected Coastal Plain Crayfishes, Samantha Lott
LSU Master's Theses
Crayfish are important for stability, determining ecosystem structure, and ecosystem functions in freshwater habitats. Louisiana has many endemic species of crayfish, but most are poorly described. This study investigated the populations of some of the lesser known crayfishes in the South Central Plains. Specifically, the goals were to examine movement, movement across anthropogenic barriers, and estimate population size of 10 species reported from the area: Procambarus natchitochae, P. vioscai, P. clarkii, P. acutus, P. zonangulus, P. tulanei, P. kensleyi, Orconectes maletae, O. lancifer, and O. palmeri. In combination with a field team, I sampled twelve wadeable streams with DC backpack …
