    Examination of Bottlenose Dolphin (Tursiops truncatus) Abundances in Relation to Environmental Factors and Risks
    (2014-08-22) Huther, Kevin David; Scott, Geoffrey I.; Owens, David; Pennington, Paul; Roumillat, Bill
    The bottlenose dolphin (Tursiops truncatus ) is the most abundant marine mammal in coastal regions of the southeastern U.S. and Gulf of Mexico. Population abundances vary throughout their range and may be influenced by various environmental factors, including food availability and environmental quality. This study measured bottlenose dolphin abundances in Charleston, South Carolina against a variety of environmental factors. Metrics measured during 420 transects in the Ashley River and Wando River included dolphin abundances, boat traffic, water quality, sediment quality, and fish abundance. Three Multiple Linear Regression (MLR) Models were used to determine if environmental factors significantly affected dolphin abundance rates. A preliminary MLR (n=263 transects) revealed that dolphin abundance rates/study block were significantly related to boats/ study block and surface salinity. A Standardized MLR analysis (n=299) used dolphin and boat observations on a survey unit of effort basis , plus water temperature class categorizations and found that dolphin abundance rates/hour were significantly related to study blocks, surface water temperature class, and sediment quality. A Maximum Likelihood ANOVA (n=300) compared categorical classification of dolphins observation rates/hour, boat traffic rates/hour, sediment quality, and mean fish abundances/net, plus each environmental water quality metric. Dolphin abundances were only significantly related to water temperature class using this categorical MLR model.

    Used to be a rough place in them hills: Illicit liquor, the Dark Corner, and the New South
    (2014-08-18) Blackwell, Joshua Beau; Gleeson, David; Poole, William S.; Moore, Bo
    The area known as the Dark Corner, near Greenville, South Carolina was once home to a distinct Appalachian culture. Isolated from their fellow South Carolinians, the Dark Corner was perceived as culturally and politically backwards throughout much of the nineteenth century. In particular, the area's reliance on illicit distillation as a cornerstone of its economy led to a protracted conflict with State and Federal law enforcement. Much of this conflict occurred during the post-Civil War modernization of the South Carolina Upstate. New South editors aggressively perpetuated the stereotype of the lawless and drunken distillers on the inhabitants of the Dark Corner. This stereotype, coupled with the Dark Corner's resistance to modernization, ostracized the local inhabitants and alienated the area from much of the economic boom of the Upstate. While the cultural mores, including the production of illicit alcohol, of the Dark Corner remained intact throughout much of the twentieth century, the area was eventually modernized by outsiders moving into upscale residential resorts dotted throughout the mountain landscape. While genealogists and popular writers have outlined some of the historical events surrounding the disputes between law enforcement and the residents of the Dark Corner, they have not placed these events in a proper cultural context. This study shows that the various conflicts over the illicit production of alcohol reflect deep cultural differences between this outpost of Appalachia and the rest of South Carolina.
