Influences Of Anthropogenic Noise On Flight Initiation Distance, Foraging Behavior, And Feeder Community Structure Of Wild Birds, Alissa R. Petrelli
Influences Of Anthropogenic Noise On Flight Initiation Distance, Foraging Behavior, And Feeder Community Structure Of Wild Birds, Alissa R. Petrelli
Master's Theses
Throughout the world, birds represent the primary type of wildlife that people experience on a daily basis. However, a growing body of evidence suggests that alterations to the acoustic environment can negatively affect birds as well as humans in a variety of ways, and altered acoustics from noise pollution has the potential to influence human interactions with wild birds. In this thesis, I investigated how anthropogenic noise impacts daily behavior as well as community structure of wild birds. In the first component of this thesis, I assessed the distance at which a bird initiates flight or escape behavior (i.e., flight …

Spatial And Temporal Heterogeneity Of Microbial Life In Artificial Landscapes, Roopkamal Kaur, Aditi Sengupta, Peter A. Troch
STAR Program Research Presentations
The Landscape Evolution Observatory (LEO) project at Biosphere 2 consists of three replicated artificial landscapes which are sealed within a climate-controlled glass house. LEO is composed of basaltic soil material with low organic matter, nutrients, and microbes. The landscapes are built to resemble zero-order basins and enables researchers to observe hydrological, biological, and geochemical evolution of landscapes in a controlled environment. This study is focused on capturing microbial community dynamics in LEO soil, pre- and post-controlled rainfall episodes. Soil samples were collected from six different positions and at five depths in each of the three slopes followed by DNA extraction …

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 …
