Effects Of Landscape Fragmentation On Land Loss, Weijia Cheng
Effects Of Landscape Fragmentation On Land Loss, Weijia Cheng
LSU Master's Theses
Coastal Louisiana, the seventh largest delta on earth, is one of the most vulnerable coastal areas in the United States of America (USA) because of its land loss problem. Coastal land loss is usually caused by many complicated factors. With the rapid increase in human activities, more studies on land loss have focused on the anthropogenic elements, but less on the pattern of the landscape. It is expected that the type of spatial arrangement, such as high degree of fragmentation, would affect the degree of land erosion. A quantitative evaluation of coastal landscape fragmentation and its influences on land loss …

Adsorption Of Aromatic Hydrocarbons At Gas-Water Interface, Suresh Raja
LSU Master's Theses
Adsorption of organic vapors at a gas-water interface has several physical applications with respect to natural processes in the environment. Understanding the adsorption processes is critical in development of risk assessment and modeling of transport and fate of various chemical species that are abundantly present in the environment. Evidences from the works of several researchers point out deviations in gas-liquid partitioning as predicted by Henry’s law. In view of several theories that describe these deviations, adsorption process is hypothesized to be significant in gas-liquid partitioning, in addition to temperature and presence of organic matter, particularly on liquid surfaces with high …
Fine-Scaled Movements And Habitat Use Of Black Bears In South Central Louisiana, Dwayne Allen Hightower
Fine-Scaled Movements And Habitat Use Of Black Bears In South Central Louisiana, Dwayne Allen Hightower
LSU Master's Theses
Animal movements are related to many parameters of interest such as the search for food and other life requisites. Several measures, including home range, have been used to quantify and describe animal movement. However, fine-scaled movements of mammals have received less attention even though they are more directly related to energy expended for locating resources and provide information on how a home range is used. I tracked radiotagged female black bears (Ursus americanus) from two geographically separate populations in the Atchafalaya River Basin in south central Louisiana: the Coastal population at the southern extent and the Inland population at the …
