The Population Genetics Of Morro Bay Eelgrass (Zostera Marina), Julia Gardner Harencar
The Population Genetics Of Morro Bay Eelgrass (Zostera Marina), Julia Gardner Harencar
Master's Theses
Seagrass populations are in decline worldwide. Zostera marina (eelgrass), one of California’s native seagrasses, is no exception to this trend. In the last 8 years, Morro Bay, California has lost 95% of its eelgrass. Eelgrass is an ecosystem engineer, providing important ecosystem services such as sediment stabilization, nutrient cycling, and nursery habitats for fish. The failure of recent restoration efforts necessitates a better understanding of the causes of eelgrass decline in this estuary. Previous research on eelgrass in California has demonstrated a link between population genetic diversity and eelgrass bed health, ecosystem functioning, and resilience to disturbance and extreme climatic …
An Assessment Of Potential False Positive E.Coli Pyroprints In The Cplop Database, Skyler A. Gordon
An Assessment Of Potential False Positive E.Coli Pyroprints In The Cplop Database, Skyler A. Gordon
Master's Theses
The genetic information found in each species of organism is unique, and can be used as a tool to differentiate at the molecular level. This has caused rapid genotyping methods to become the cornerstone of a new area of research dependent on reading the genome as a form of identification. One of these specific identification methods, known as pyroprinting, relies on the small variation of DNA sequences within the same species to develop a unique, reproducible fingerprint. By simultaneously pyrosequencing multiple polymorphic loci within the ribosomal operons known as the intergenic transcribed spacers, a reproducible output is obtained, known as …
The Role Of Phage Trnas In The Evolution Of Codon Usage Biases In Giant Pseudomonas Phage Phikz And El, Stephanie Steidel
The Role Of Phage Trnas In The Evolution Of Codon Usage Biases In Giant Pseudomonas Phage Phikz And El, Stephanie Steidel
Master's Theses
As the most abundant and diverse biological agents in the biosphere phage have significant roles in microbial ecology, acting both as lethal bacterial parasites and vehicles of horizontal gene transfer. Phage/host coevolution drives optimization of phage codon usage for use of host translational machinery, thus lowered correspondence between phage and host codon usage reduces viral fitness. Some phage may partially bypass host translational selection on their codon usage by encoding their own tRNAs, although the effects of these tRNAs on phage codon usage and translation has not been well examined. This work explores the influence of phage encoded tRNAs on …
