Effects Of Mass Death On Community Structure And Ecosystem Function, Abby Kimpton Jones
Effects Of Mass Death On Community Structure And Ecosystem Function, Abby Kimpton Jones
Theses and Dissertations
Death and decomposition are natural processes that are generally well-understood. However, large events of death, such as mass mortality events (MMEs) are increasing in frequency and their impacts on the ecosystem are largely unknown. These events may have both bottom-up effects from increased nutrient input as well as top-down effects from loss of an ecological functional group by the affected population. Different functional MMEs may result in different top-down effects, creating cascading effects. In Chapter 1, I test the hypothesis that scavenger and herbivore simulated MMEs generate novel bottom-up and top-down effects. Results indicate that MMEs have a significant effect …

The confirmatory identification of body fluids is one of the most critical steps in criminal investigations, as it provides not only information on the source of the DNA, but it can corroborate evidence, aid in the reconstruction of a crime, and associate evidence with a person of interest. Current serological methods utilize biochemistry and immunology to identify biological evidence; however, these serological tests are mostly presumptive while only testing for one fluid at a time, potentially wasting precious evidence. More recently, forensic investigators have suggested the use of molecular methods such as mRNA, miRNA, or DNA methylation. While each of …
