Complex Effects Of Nitrogen Pollution And Grazing On Nectar Resources Of The Adult Bay Checkerspot Butterfly (Euphydryas Editha Bayensis), Nidhi Jain

Master's Theses

Recent anthropogenic increases in atmospheric nitrogen due to urbanization and combustion have had many adverse effects on natural systems, including loss of biodiversity, especially in sensitive habitats. One such region is the serpentine ecosystem of Coyote Ridge in San Jose, CA, the last refuge for recurring populations of the federally threatened Bay Checkerspot Butterfly (BCB) (Euphydryas editha bayensis). Increases in non-native grass cover and decreases in native forb cover (including cover of the BCB’s native larval host plants) have been attributed to the fertilizing effects of increased atmospheric nitrogen deposition. To counteract this effect, grazing has been implemented as a …

Chloroflexi: The Tale Of A Bacterium Present In Human And Environmental Habitats, Jayashree Sanjeeviraman

Master's Theses

The phylum Chloroflexi is relatively unexplored, with the majority of its representatives being uncultivable. As a result, these microorganisms have not been characterized beyond their morphology and simple staining reactions, making the study of this phylum extremely challenging. Chloroflexi has been detected in the human oral cavity of patients suffering from peri-implantitis and in the vagina of patients suffering from bacterial vaginosis. Interestingly, Chloroflexi is also present in various environments such as freshwater lakes, soil, deep-sea sponges, hot springs and activated wastewater. Isolation of an environmental Chloroflexi with high 16S rRNA gene homology to a human-associated counterpart could be used …

The Role Of Nitric Oxide In Skeletal Simulated Microgravity Response, Luan Tran

Master's Theses

Prolonged exposure to the space environment leads to bone loss. Using a ground-based model for microgravity (hind-limb unloading), it has been shown in rodents that proliferation and differentiation activity of osteoprogenitors are decreased with exposure to simulated microgravity (Kostenuik et al., 1997). Osteoblast mineralization activity has been shown to increase with nitric oxide supplementation (Afzal et al., 2004; Koyama et al., 2000). I hypothesized that the degenerative effects of microgravity exposure result from chronic changes in nitric oxide regulation in osteoprogenitors, and that supplementation with exogenous nitric oxide following exposure would ameliorate these changes. In 20 C57Bl/6 mice, hind-limb unloading …

Geographic Variation In The Life History And Morphology Of The Pacific Geoduck, Panopea Generosa, Gabriela Navas

Master's Theses

The Pacific geoduck, Panopea generosa, is an ideal candidate to investigate patterns of life history variation and morphological plasticity in shell shape, as it occurs over a large geographic range, inhabits different marine environments, and experiences intense fishing pressure in some locations (i.e., Mexico and Washington). Six populations were sampled from Washington to Mexico to evaluate evidence for geographic variation in demography, life history, and morphology. Results provided evidence for a latitudinal cline with larger clams occurring in locations characterized by colder water temperature. Age structure and longevity analyses indicated that life expectancy was significantly lowered at intertidal sites compared …

Burnout Versus Personality: Predicting Volunteer Retention, Conor Thomas Tuohy

Master's Theses

Employee turnover is an important issue for any organization, but it is of critical importance for volunteer organizations. Research shows that a strong predictor of volunteer turnover is a volunteer’s intention to remain in that organization. This study measured volunteers’ intention to remain and compared the known predictor of burnout to the potential predictor of personality (through personality traits) in order to find a better predictor of a volunteer’s intention to remain in an organization. Using survey data obtained from 65 participants from a single volunteer organization, this study showed that burnout and personality traits failed to predict a volunteer’s …

High-Speed Rail And Equine Issues, Peter J. Haas, Allie Scrivener

Mineta Transportation Institute

Community concerns have been raised about the possible negative impacts of high-speed rail (HSR) service on equestrian areas. Although much is known about the impact of aircraft noise on wild and domestic animals, relatively little information is available on the potential impact of HSR service on equine populations. This study will explore possible conflicts between HSR construction and operations in areas used for equestrian ranching, recreation, and related activities, and identify geographic areas where such conflicts could occur.

Environmental Temperatures, Artificial Nests, And Incubation Of Cassin's Auklet, Emma Kelsey, Russell Bradley, Pete Warzybok, Jamie Jahncke, Scott A. Shaffer

Faculty Publications, Biological Sciences

Hatching success in birds is influenced by the temperature and turning rate of the egg, but our understanding of the environmental factors that effect incubation temperatures and egg turning rates in birds is limited. Especially little is known of these effects for species that nest in burrows or crevices, such as the Cassin's auklet. On Southeast Farallon Island, California, USA, a subset of the Cassin's auklet (hereafter auklet) population nest in artificial nest boxes. The nest boxes are above ground and made out of a single layer of plywood. Temperatures in unshaded nest boxes can increase significantly with high ambient …

Individual-Level Variation And Higher-Level Interpretations Of Space Use In Wide-Ranging Species: An Albatross Case Study Of Sampling Effects, Sarah Gutowsky, Marty Leonard, Melinda Conners, Scott A. Shaffer, Ian Jonsen

Faculty Publications, Biological Sciences

Marine ecologists and managers need to know the spatial extent of at-sea areas most frequented by the groups of wildlife they study or manage. Defining group-specific ranges and distributions (i.e., space use at the level of species, population, age-class, etc.) can help to identify the source or severity of common or distinct threats among different at-risk groups. In biologging studies, this is accomplished by estimating the space use of a group based on a sample of tracked individuals. A major assumption of these studies is consistency in individual movements among members of a group. The implications of scaling up individual-level …

Body Size Affects Individual Winter Foraging Strategies Of Thick-Billed Murres In The Bering Sea, Rachael Orben, Rosana Paredes, Daniel Roby, David Irons, Scott A. Shaffer

Faculty Publications, Biological Sciences

Foraging and migration often require different energetic and movement strategies. Though not readily apparent, constraints during one phase might influence the foraging strategies observed in another. For marine birds that fly and dive, body size constraints likely present a trade-off between foraging ability and migration as smaller bodies reduce flight costs, whereas larger bodies are advantageous for diving deeper. This study examines individual wintering strategies of deep diving thick-billed murres (Uria lomvia) breeding at three colonies in the south-eastern Bering Sea: St Paul, St George and Bogoslof. These colonies, arranged north to south, are located such that breeding birds forage …

This session explains ICT literacy, especially in terms of new standards. Attendees will find out how MERLOT supports ICT literacy, and how they can join and contribute to the ICT literacy community.

Wintering North Pacific Black-Legged Kittiwakes Balance Spatial Flexibility And Consistency, Rachael Orben, Rosana Paredes, Daniel Roby, David Irons, Scott A. Shaffer

Faculty Publications, Biological Sciences

Background Marine environments are inherently dynamic, yet marine predators are often long-lived and employ strategies where consistency, individual specialization, routine migrations, and spatial memory are key components to their foraging and life-history strategies. Intrinsic determinates of animal movements are linked to physiological and life-history traits (e.g. sex, colony, experience), while extrinsic influences occur as the result of an animal’s interactions with either other animals or the environment (e.g. prey availability, weather, competition). Knowledge of the factors affecting animal movements is critical to understand energetic bottlenecks and population dynamics. Here, we attempt to understand the interaction of some of these factors …

Foraging Behavior Links Climate Variability And Reproduction In North Pacific Albatrosses, Lesley Thorne, Elliott Hazen, Steven Bograd, David Foley, Melinda Conners, Michelle Kappes, Hyemi Kim, Daniel Costa, Yann Tremblay, Scott A. Shaffer

Faculty Publications, Biological Sciences

Background: Climate-driven environmental change in the North Pacific has been well documented, with marked effects on the habitat and foraging behavior of marine predators. However, the mechanistic linkages connecting climate-driven changes in behavior to predator populations are not well understood. We evaluated the effects of climate-driven environmental variability on the reproductive success and foraging behavior of Laysan and Black-footed albatrosses breeding in the Northwest Hawaiian Islands during both brooding and incubating periods. We assessed foraging trip metrics and reproductive success using data collected from 2002–2012 and 1981–2012, respectively, relative to variability in the location of the Transition Zone Chlorophyll Front …

Pattern-Driven Programming In Scala, Huaxin Pang

Master's Projects

This is an experimental exploration of the pattern-driven programming paradigm—the sole use of pattern matching to determine the next instruction or execute. We define a pure pattern-driven programming language named PA-Scala by defining a subset of the Scala programming language, which restricts sequence control to the powerful pattern matching facilities in Scala. We use PA-Scala to explore the strengths and limitations of pattern-driven programming. By implementing a phrase structure grammar solver in PA-Scala, we show that pattern-driven programming can be used to solve general computation problems. We then implement a Prolog interpreter in PA-Scala, which demonstrates how resolution and unification …
