Directional Preference In Drosophila Melanogaster, Taylor James, Michael Baltzley, Eli Zachary, Spicie Davis, Kristin Latham 2016 Western Oregon University

Directional Preference In Drosophila Melanogaster, Taylor James, Michael Baltzley, Eli Zachary, Spicie Davis, Kristin Latham

PURE Insights

Diverse organisms have been shown to use the Earth’s magnetic field for orientation and navigation, but the mechanisms underlying magnetoreception are still poorly understood. Recent research on magnetoreception has focused on the fruit fly Drosophila melanogaster primarily because of its role as a model organism for understanding the genetic mechanisms underlying behavioral traits. While current research suggests that Drosophila might be able to detect and orient to magnetic fields, different studies offer contradictory results. In this study, we used a Y-maze and selective breeding to attempt to create a population of fruit flies that display a robust magnetic orientation ...

Chapman University 2016 Environmental Audit: Residence Life Dining Services Equipment, Alexandra Fw Sidun, Devon T. Bloss

Student Research Day Abstracts and Posters

Chapman University accommodates over 1700 student meal plans per day through the on-campus dining services provided by Sodexo Restaurant Services. The commercial-grade kitchens found in the Randall Dining Commons (RDC) of Sandhu Conference Center are frequently used to prepare food for students for every meal, seven days a week. The RDC kitchen facility has staff working around the clock and high consumption electrical, water, and gas appliances constantly running to parallel the high demand. The frequent use of commercial kitchen appliances results in an enormous consumption of energy and water resources leading to comparably high utility bills. Measuring the energy ...


Ocean Acidification And Predator-Prey Relations: Correlating Disruption Of Predator Avoidance With Chemosensory Deficits, Alexandra FW Sidun 2016 Chapman University

Ocean Acidification And Predator-Prey Relations: Correlating Disruption Of Predator Avoidance With Chemosensory Deficits, Alexandra Fw Sidun

Student Research Day Abstracts and Posters

One of the most destructive effects of global climate change is the increased carbon sequestering and consequential acidification of our world’s oceans. The impacts of ocean acidification on marine organisms are still relatively unknown, especially effects on behavioral ecology. Avoiding predation has emerged from recent behavioral ecology literature as a critical feature in the life history of a wide array of animal species; experiments on marine fishes suggest acidic water compromises their predator-avoidance abilities. Recent assays in our lab suggest predator-induced behavior is reduced by weakly acidic water. These experiments do not address the potential factor of generalized malaise ...

Development Of A Decision Support System For Post Mining Land Use On Abandoned Surface Coal Mines In Appalachia, Matthew Zimmerman 2016 Clark University

Development Of A Decision Support System For Post Mining Land Use On Abandoned Surface Coal Mines In Appalachia, Matthew Zimmerman

International Development, Community and Environment (IDCE)

Decision support systems are diverse and have been used to solve multiple problems ranging from the complex to the simple. With the complexity of environmental decisions today, these systems provide a logic based approach to evaluating and choosing environmental solutions. Abandoned mining lands (AML) are an issue for the environment in the Appalachian region. Given this a decision support system was designed using previously created frameworks and indices from other systems created. The system is comprised of two main sections, selecting the ideal post-mining land-use (PMLU), and maximizing the potential of land to be reclaimed under budgetary constraints. This system ...


Variation In Vegetation And Microbial Linkages With Slope Aspect In A Montane Temperate Hardwood Forest, Frank S. Gilliam, Radim Hedl, Marketa Chudomelova, Rebecca L. McCulley, Jim Nelson 2016 Marshall University

Variation In Vegetation And Microbial Linkages With Slope Aspect In A Montane Temperate Hardwood Forest, Frank S. Gilliam, Radim Hedl, Marketa Chudomelova, Rebecca L. Mcculley, Jim Nelson

Frank S. Gilliam

Plant ecologists have long been interested in aspect-related contrasts of montane forests. Few studies have assessed correlation (linkage) among vegetation strata; fewer have included soil microbial communities. This study assessed contrasts in overstory, spring herbaceous, and soil microbial communities between northeast (NE) - and southwest (SW) -facing slopes in a second-growth West Virginia hardwood forest. We addressed three questions: (1) how do soil microbial, herbaceous layer, and overstory communities vary with slope aspect? (2) do forest vegetation strata and soil microbial communities exhibit linkage? (3) do biotic relationships and linkage vary with slope aspect? Moisture, organic matter, pH, soil NO3 ...

Nutrient Limitation In Three Lowland Tropical Forests In Southern China Receiving High Nitrogen Deposition: Insights From Fine Root Responses To Nutrient Additions, Feifei Zhu, Muneoki Yoh, Frank S. Gilliam, Xiankai Lu, Jiangming Mo

Frank S. Gilliam

Elevated nitrogen (N) deposition to tropical forests may accelerate ecosystem phosphorus (P) limitation. This study examined responses of fine root biomass, nutrient concentrations, and acid phosphatase activity (APA) of bulk soil to five years of N and P additions in one old-growth and two younger lowland tropical forests in southern China. The old-growth forest had higher N capital than the two younger forests from long-term N accumulation. From February 2007 to July 2012, four experimental treatments were established at the following levels: Control, N-addition (150 kg N ha–1 yr–1), P-addition (150 kg P ha–1 yr–1) and ...

Spatial Variation In Carbon And Nitrogen In Cultivated Soils In Henan Province, China: Potential Effect On Crop Yield, Xuelin Zhang, Qun Wang, Frank S. Gilliam, Yilun Wang, Feina Cha, Chaohai Li

Frank S. Gilliam

Improved management of soil carbon (C) and nitrogen (N) storage in agro-ecosystems represents an important strategy for ensuring food security and sustainable agricultural development in China. Accurate estimates of the distribution of soil C and N stores and their relationship to crop yield are crucial to developing appropriate cropland management policies. The current study examined the spatial variation of soil organic C (SOC), total soil N (TSN), and associated variables in the surface layer (0–40 cm) of soils from intensive agricultural systems in 19 counties within Henan Province, China, and compared these patterns with crop yield. Mean soil C ...

Atmospheric nitrogen (N) deposition has been shown to decrease plant species richness along regional deposition gradients in Europe and in experimental manipulations. However, the general response of species richness to N deposition across different vegetation types, soil conditions, and climates remains largely unknown even though responses may be contingent on these environmental factors. We assessedtheeffectofNdepositiononherbaceousrichnessfor15,136 forest, woodland, shrubland, and grassland sites across the continental United States, to address how edaphic and climatic conditions altered vulnerability to this stressor. In our dataset, with N deposition ranging from 1 to 19 kg N·ha−1·y−1, we found a unimodal ...

Nursing Faculty's Needs Of Knowledge, Beliefs, And Readiness To Implement Interprofessional Education In Their Teaching: An Exploratory Study, Louise Racine, Hope Bilinski, Paul Spriggs 2016 University of Saskatchewan

Nursing Faculty's Needs Of Knowledge, Beliefs, And Readiness To Implement Interprofessional Education In Their Teaching: An Exploratory Study, Louise Racine, Hope Bilinski, Paul Spriggs

Quality Advancement in Nursing Education - Avancées en formation infirmière

The drive towards interprofessional health education in nursing cannot be isolated from political and financial factors that affect Western countries and the demands for knowledge and skills required to face the health challenges of the 21st century. Complex social determinants of health relating to demographic aging, health inequities, higher prevalence of non-communicable illnesses, and the rise of health care costs constitute the forces that push for the delivery of interprofessional health education. Despite the growing literature on interprofessional education in nursing and health sciences, less attention has been devoted to studying the needs of faculty development needs of nurse ...

Watershed Sciences Faculty Publications

Stream classification provides a means to understand the diversity and distribution of channels and floodplains that occur across a landscape while identifying links between geomorphic form and process. Accordingly, stream classification is frequently employed as a watershed planning, management, and restoration tool. At the same time, there has been intense debate and criticism of particular frameworks, on the grounds that these frameworks classify stream reaches based largely on their physical form, rather than direct measurements of their component hydrogeomorphic processes. Despite this debate surrounding stream classifications, and their ongoing use in watershed management, direct comparisons of channel classification frameworks are ...


Swans: Their Biology And Natural History, Paul A. Johnsgard 2016 University of Nebraska-Lincoln

Swans: Their Biology And Natural History, Paul A. Johnsgard

Zea E-Books

The seven species of swans of the world are an easily and universally recognized group of waterfowl, which have historically played important roles in the folklore, myths and legends in many of the world’s cultures. Among the largest of all flying birds, they have also almost universally been used as symbols of royalty, grace and beauty, and largely for these reasons swans have only rarely been considered acceptable as targets for sport hunting. Swans occur on all the continents except Africa, although most species are associated with the temperate and arctic zones of North America and Eurasia. Among birds ...

Calmly Coping: A Motivational Interviewing Via Co-Active Life Coaching (Mi-Via-Calc) Pilot Intervention For University Students Suffering From Stress, Rebecca Fried, Jennifer Irwin 2016 The University of Western Ontario

Calmly Coping: A Motivational Interviewing Via Co-Active Life Coaching (Mi-Via-Calc) Pilot Intervention For University Students Suffering From Stress, Rebecca Fried, Jennifer Irwin

Jennifer D. Irwin

The purpose of this semester-long pilot study was to assess the impact of Motivational Interviewing via Co-Active Life Coaching (MI-via-CALC) on the stress management experiences of 30 full-time, English-speaking students aged 17-24 years. Participants’ experiences were assessed quantitatively using the previously validated Perceived Stress Scale and Hospital Anxiety and Depression Scale (which is divided into Anxiety and Depression scales) at pre-, mid-, and post-intervention. Three one-way, repeated-measures ANOVAs were completed for each scale and statistically significant differences in stress reduction were found for all scales between pre-intervention to mid-intervention, and between pre-intervention to post- intervention; no statistically significant differences occurred ...


Movement Path Tortuosity In Free Ambulation: Relationships To Age And Brain Disease, William Kearns, James Fozard, Vilis Nams 2016 University of South Florida

Movement Path Tortuosity In Free Ambulation: Relationships To Age And Brain Disease, William Kearns, James Fozard, Vilis Nams

William D. Kearns, PhD

Ambulation is defined by duration, distance traversed, number and size of directional changes and the interval separating successive movement episodes; more complex measures of ambulation can be created by aggregating these features. This review article of published findings defines random changes in direction during movement as “movement path tortuosity”, and relates tortuosity to the understanding of cognitive impairments of persons of all ages. Path tortuosity is quantified by subjecting tracking data to fractal analysis, specifically Fractal Dimension (Fractal D), which ranges from a value of 1 when the movement path is perfectly straight to a value of 2 when the ...


Going Mainstream Or Just A Passing Fad? The Future Of The Ancestral Health Movement, Hamilton M. Stapell 2016 SUNY New Paltz

Going Mainstream Or Just A Passing Fad? The Future Of The Ancestral Health Movement, Hamilton M. Stapell

Journal of Evolution and Health

The current ancestral health (“paleo”) movement is often thought to be on the verge of going mainstream. Many within the movement believe this would lead to positive health and financial outcomes for both individuals and society as a whole. However, the transition from a small, highly-devoted group of adherents to a mass following will be far more difficult than commonly assumed. This paper argues there are three main obstacles to it becoming a mass phenomenon in the United States. First, Neolithic foods are tightly woven into the fabric of our culture (for example, bread within the Christian tradition). Second, refined ...
