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 ...


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 ...

The Blurred Line Between Form And Process: A Comparison Of Stream Channel Classification Frameworks, Alan Kasprak, Nate Hough-Snee, Tim Beechie, Nicolaas Bouwes, Gary Brierley, Reid Camp, Kirstie Fryirs, Hiroo Imaki, Martha Jensen, Gary O'Brien, David Rosgen, Joseph Wheaton

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 ...

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 assessed the effect of N deposition on herbaceous richness for15,136 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 ...


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 ...

Killer Toxin From Several Food-Derived Debaryomyces Hansenii Strains Effective Against Pathogenic Candida Yeasts, Nabaraj Banjara, Kenneth Nickerson, Mallory J. Suhr, Heather E. Hallen-Adams 2016 University of Nebraska-Lincoln

Killer Toxin From Several Food-Derived Debaryomyces Hansenii Strains Effective Against Pathogenic Candida Yeasts, Nabaraj Banjara, Kenneth Nickerson, Mallory J. Suhr, Heather E. Hallen-Adams

Kenneth Nickerson Papers

Candida yeasts are the dominant fungi in the healthy human microbiome, but are well-known for causing disease following a variety of perturbations. Evaluation of fungal populations from the healthy human gut revealed a significant negative correlation between the foodborne yeast, Debaryomyces hansenii, and Candida species. D. hansenii is reported to produce killer toxins (mycocins) effective against other yeast species. In order to better understand this phenomenon, a collection of 42 D. hansenii isolates was obtained from 22 cheeses and evaluated for killer activity against Candida albicans and Candida tropicalis over a range of temperatures and pH values. Twenty three strains ...


Grass-Shrub Associations Over A Precipitation Gradient And Their Implications For Restoration In The Great Basin, Usa, Maike F. Holthuijzen, Kari E. Veblen 2015 Utah State University

Grass-Shrub Associations Over A Precipitation Gradient And Their Implications For Restoration In The Great Basin, Usa, Maike F. Holthuijzen, Kari E. Veblen

Wildland Resources Faculty Publications

As environmental stress increases positive (facilitative) plant interactions often predominate. Plant-plant associations (or lack thereof) can indicate whether certain plant species favor particular types of microsites (e.g., shrub canopies or plant-free interspaces) and can provide valuable insights into whether “nurse plants” will contribute to seeding or planting success during ecological restoration. It can be difficult, however, to anticipate how relationships between nurse plants and plants used for restoration may change over large-ranging, regional stress gradients. We investigated associations between the shrub, Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis), and three common native grasses (Poa secunda, Elymus elymoides, and Pseudoroegneria ...

Rapid Purging Of Genetic Load In A Metapopulation And Consequences For Range Expansion In An Invasive Plant, Gina Marchini, Nena Sherlock, Alisa Ramakrishnan, David Rosenthal, Mitchell Cruzan 2015 Portland State University

Rapid Purging Of Genetic Load In A Metapopulation And Consequences For Range Expansion In An Invasive Plant, Gina Marchini, Nena Sherlock, Alisa Ramakrishnan, David Rosenthal, Mitchell Cruzan

Mitchell B. Cruzan

Invasive species often display high fitness despite bottlenecks and inbreeding during establishment. We address this paradox through simulations and experiments that assess the potential for purging of genetic load during range expansion. Success of invaders often depends on the production of vigorous inbred offspring allowing for rapid population growth after colonization. Substantial genetic load of outbreeding species reduces the fitness of offspring as inbreeding ensues during the establishment of populations. In our simulations, sustained selfing or outcrossing within isolated populations did little to remove deleterious mutations. Conversely, inbreeding combined with periodic gene flow resulted in efficient purging and accelerated rates ...

Morphological And Molecular Systematics Of Resupinatus (Basidiomycota), Jennifer McDonald 2015 The University of Western Ontario

Morphological And Molecular Systematics Of Resupinatus (Basidiomycota), Jennifer Mcdonald

Electronic Thesis and Dissertation Repository

Cyphelloid fungi are, compared to their gilled relatives, poorly studied and understood. Within the tribe Resupinateae (which includes the genera Resupinatus, Stigmatolemma, Aphyllotus and Stromatocyphella), little is known about the evolution of the cyphelloid fruit body form. How many times has this reduced morphology evolved within the group? Do all cyphelloid members that are currently treated in this group belong there? Are there other described species of cyphelloid fungi currently treated in other genera that belong within the Resupinateae? This study presents phylogenies of the cyphelloid and small lamellate members of the Resupinateae based on rDNA sequences to illustrate the ...
