A Comparative Study Of The Effects Of River Flow Rates On Decomposition, Maddisen Paige Neuman
A Comparative Study Of The Effects Of River Flow Rates On Decomposition, Maddisen Paige Neuman
LSU Master's Theses
While the general biological processes of decomposition are known to forensic anthropologists, data on aquatic decomposition is in need of refinement. Water composition varies in mineral content, temperature, flow rate, and scavengers; each of these elements can have an effect on the rate of decomposition. This study specifically focuses on the effects of river flow rates on decomposition by comparing the rate of decay of three feral pigs (Sus scrofa) on land (control specimen), in faster flowing water, and in slower flowing water. The hypothesis states that the pig placed in the faster section of the river will decompose more …

On-Site Sperm Cryopreservation For Aquatic Repository Development And User Group Linkage, William Martin Childress
LSU Master's Theses
Although on-site cryopreservation of aquatic species sperm in nitrogen-vapor shipping dewars has been used for more than 30 yr, many limitations remain. Due to the size of shipping dewars, most studies are small scale and can only produce tens of samples. The freezing temperatures that can be achieved are also affected by the size of the dewar and the number of samples being frozen due to the heat load. In addition, often due to timing or remote location these samples cannot be shipped, and if they are shipped, quality can be lost and the samples must be discarded. The goal …
