Description
The Mormon Plan of Salvation explains that people originate in a heavenly state and are sent to Earth in a physical form, where they aspire to lead good lives and gain wisdom in order to reach glory in the afterlife. The dance piece "From There to Here to There: Whose Journey is it Anyway?" explores each stage in the Plan of Salvation at a different location, requiring dancers and audience to travel both metaphorically and physically. The piece incorporates several kinds of journeys: the collective journey of humankind based on the Plan of Salvation, the dancers' own journeys, and audience's journey as they watch the piece, and my journey as an artist. In the process of making this piece, I refined my identity as a 21st century Mormon artist interested in conveying religious messages through the traditionally secular art form of postmodern dance.

Description
The purpose of my creative research was to analyze my choreographic process and answer the research question: how will implementing somatic principles impact my choreographic process? In determining the impact I analyzed the use of choreographic approaches that bring proprioceptive awareness to interdisciplinary somatic themes of bodily systems, sensing, connectivity, initiation and sequencing. These somatic themes were utilized in movement invention and exploration as well as the structuring and performance of my choreography. Additionally, the research involved clarifying my role as a choreographer and my relationship to the dancers in my work. My creative research occurred in three choreographic phases and resulted in the production of B.O.D.I.E.S performed in three consecutive sections titled Discovery, Exploration, and Identity November 5-7, 2010. B.O.D.I.E.S demonstrates how somatics will lead to greater movement possibilities and dynamic range to explore in the craft of dance making.

Description
Like individual organisms, complex social groups are able to maintain predictable trajectories of growth, from initial colony foundation to mature reproductively capable units. They do so while simultaneously responding flexibly to variation in nutrient availability and intake. Leafcutter ant colonies function as tri-trophic systems, in which the ants harvest vegetation to grow a fungus that, in turn, serves as food for the colony. Fungal growth rates and colony worker production are interdependent, regulated by nutritional and behavioral feedbacks. Fungal growth and quality are directly affected by worker foraging decisions, while worker production is, in turn, dependent on the amount and condition of the fungus. In this dissertation, I first characterized the growth relationship between the workers and the fungus of the desert leafcutter ant Acromyrmex versicolor during early stages of colony development, from colony foundation by groups of queens through the beginnings of exponential growth. I found that this relationship undergoes a period of slow growth and instability when workers first emerge, and then becomes allometrically positive. I then evaluated how mass and element ratios of resources collected by the ants are translated into fungus and worker population growth, and refuse, finding that colony digestive efficiency is comparable to digestive efficiencies of other herbivorous insects and ruminants. To test how colonies behaviorally respond to perturbations of the fungus garden, I quantified activity levels and task performance of workers in colonies with either supplemented or diminished fungus gardens, and found that colonies adjusted activity and task allocation in response to the fungus garden size. Finally, to identify possible forms of nutrient limitation, I measured how colony performance was affected by changes in the relative amounts of carbohydrates, protein, and phosphorus available in the resources used to grow the fungus garden. From this experiment, I concluded that colony growth is primarily carbohydrate-limited.

Description
MOVE was a choreographic project that investigated content in conjunction with the creative process. The yearlong collaborative creative process utilized improvisational and compositional experiments to research the movement potential of the human body, as well as movement's ability to be an emotional catalyst. Multiple showings were held to receive feedback from a variety of viewers. Production elements were designed in conjunction with the development of the evening-length dance work. As a result of discussion and research, several process-revealing sections were created to provide clear relationships between pedestrian/daily functional movement and technical movement. Each section within MOVE addressed movement as an emotional catalyst, resulting in a variety of emotional textures. The sections were placed in a non-linear structure in order for the audience to have the space to create their own connections between concepts. Community was developed in rehearsal via touch/weight sharing, and translated to the performance of MOVE via a communal, instinctive approach to the performance of the work. Community was also created between the movers and the audience via the design of the performance space. The production elements all revolved around the human body, and offered different viewpoints into various body parts. The choreographer, designers, and movers all participated in the creation of the production elements, resulting in a clear understanding of MOVE by the entire community involved. The overall creation, presentation, and reflection of MOVE was a view into the choreographer's growth as a dance artist, and her values of people and movement.

Description
A Sense Of is a performance-based work that addresses the effects of the transformation of space, time, and energy through the various sensory modes. The work is an invitation to the artist's perspective of the world, which is combined with the performers' creative voices and interpretations of the artist's explorations into sensory awareness. The movement installation entitled A Sense Of was presented in November 2011. This document presents an overview of the project. It addresses relevant literature, examines the creative process used in the work, and provides an analysis of the project as a whole.

Description
Land management practices such as domestic animal grazing can alter plant communities via changes in soil structure and chemistry, species composition, and plant nutrient content. These changes can affect the abundance and quality of plants consumed by insect herbivores with consequent changes in population dynamics. These population changes can translate to massive crop damage and pest control costs. My dissertation focused on Oedaleus asiaticus, a dominant Asian locust, and had three main objectives. First, I identified morphological, physiological, and behavioral characteristics of the migratory ("brown") and non-migratory ("green") phenotypes. I found that brown morphs had longer wings, larger thoraxes and higher metabolic rates compared to green morphs, suggesting that developmental plasticity allows greater migratory capacity in the brown morph of this locust. Second, I tested the hypothesis of a causal link between livestock overgrazing and an increase in migratory swarms of O. asiaticus. Current paradigms generally assume that increased plant nitrogen (N) should enhance herbivore performance by relieving protein-limitation, increasing herbivorous insect populations. I showed, in contrast to this scenario, that host plant N-enrichment and high protein artificial diets decreased the size and viability of O. asiaticus. Plant N content was lowest and locust abundance highest in heavily livestock-grazed fields where soils were N-depleted, likely due to enhanced erosion and leaching. These results suggest that heavy livestock grazing promotes outbreaks of this locust by reducing plant protein content. Third, I tested for the influence of dietary imbalance, in conjunction with high population density, on migratory plasticity. While high population density has clearly been shown to induce the migratory morph in several locusts, the effect of diet has been unclear. I found that locusts reared at high population density and fed unfertilized plants (i.e. high quality plants for O. asiaticus) had the greatest migratory capacity, and maintained a high percent of brown locusts. These results did not support the hypothesis that poor-quality resources increased expression of migratory phenotypes. This highlights a need to develop new theoretical frameworks for predicting how environmental factors will regulate migratory plasticity in locusts and perhaps other insects.

Description
Many studies over the past two decades examined the link between climate patterns and discharge, but few have attempted to study the effects of the El Niño Southern Oscillation (ENSO) on localized and watershed specific processes such as nutrient loading in the Southwestern United States. The Multivariate ENSO Index (MEI) is used to describe the state of the ENSO, with positive (negative) values referring to an El Niño condition (La Niña condition). This study examined the connection between the MEI and precipitation, discharge, and total nitrogen (TN) and total phosphorus (TP) concentrations in the Upper Salt River Watershed in Arizona. Unrestricted regression models (UMs) and restricted regression models (RMs) were used to investigate the relationship between the discharges in Tonto Creek and the Salt River as functions of the magnitude of the MEI, precipitation, and season (winter/summer). The results suggest that in addition to precipitation, the MEI/season relationship is an important factor for predicting discharge. Additionally, high discharge events were associated with high magnitude ENSO events, both El Niño and La Niña. An UM including discharge and season, and a RM (restricting the seasonal factor to zero), were applied to TN and TP concentrations in the Salt River. Discharge and seasonality were significant factors describing the variability in TN in the Salt River while discharge alone was the significant factor describing TP. TN and TP in Roosevelt Lake were evaluated as functions of both discharge and MEI. Some significant correlations were found but internal nutrient cycling as well as seasonal stratification of the water column of the lake likely masks the true relationships. Based on these results, the MEI is a useful predictor of discharge, as well as nutrient loading in the Salt River Watershed through the Salt River and Tonto Creek. A predictive model investigating the effect of ENSO on nutrient loading through discharge can illustrate the effects of large scale climate patterns on smaller systems.

Description
It is well known that deficiencies in key chemical elements (such as phosphorus, P) can reduce animal growth; however, recent empirical data have shown that high levels of dietary nutrients can also reduce animal growth. In ecological stoichiometry, this phenomenon is known as the "stoichiometric knife edge," but its underlying mechanisms are not well-known. Previous work has suggested that the crustacean zooplankter Daphnia reduces its feeding rates on phosphorus-rich food, causing low growth due to insufficient C (energy) intake. To test for this mechanism, feeding rates of Daphnia magna on algae (Scenedesmus acutus) differing in C:P ratio (P content) were determined. Overall, there was a significant difference among all treatments for feeding rate (p < 0.05) with generally higher feeding rates on P-rich algae. These data indicate that both high and low food C:P ratio do affect Daphnia feeding rate but are in contradiction with previous work that showed that P-rich food led to strong reductions in feeding rate. Additional experiments are needed to gain further insights.

Description
My intention with this project was multifaceted; my goal was to articulate in words and share through physical embodiment what dance means to me and how dance has helped shape me as an individual. In doing so, I delved into an exploration of defining dance and its role within my life and in society at large. Inspired by the black and white, silent film The Artist, I began pondering how important external elements such as music, lighting, and color are when choreographing work and furthermore sharing it with an audience. For most mainstream concert dance choreographers, these elements are an integral part of the artistic process and factor into the totality of a performance experience as a work comes into fruition. The title of my thesis, A Composition of Dance, is a play on words in my attempt to challenge my own notion of dance and investigate how one's senses and environment can influence one's perception of dance from both the performer and audience perspective.

Description
Many studies have shown that as the calcium carbonate precipitates, it sequesters phosphate. Although the geochemical interactions between phosphate and calcium carbonate are known, only a few studies have considered calcium carbonate deposition's effect on stream ecology. Further, those studies considering decomposition have produced conflicting results. In this study, nutrient-diffusing cups with organic substrata were used to determine the nutrient limitation of decomposers in the travertine streams in the Huachuca Mountains. After processing a subset of the experiments, only one site (in Huachuca Canyon) from the four study streams was significantly nutrient-limited (NP co-limitation).
