The Effects Of Electric Power Lines On The Breeding Ecology Of Greater Sage-Grouse, Michel T. Kohl, Terry A. Messmer, Benjamin A. Crabb, Michael R. Guttery, David K. Dahlgren, Randy T. Larsen, Shandra Nicole Frey, Sherry Liguori, Rick J. Baxter

Wildland Resources Faculty Publications

Anthropogenic infrastructure can negatively affect wildlife through direct mortality and/or displacement behaviors. Some tetranoids (grouse spp.) species are particularly vulnerable to tall anthropogenic structures because they evolved in ecosystems void of vertical structures. In western North America, electric power transmission and distribution lines (power lines) occur in sagebrush (Artemisia spp.) landscapes within the range of the greater sage-grouse (Centrocercus urophasianus; sage-grouse). The U.S. Fish and Wildlife Service recommended using buffer zones near leks to mitigate the potential impacts of power lines on sage-grouse. However, recommended buffer distances are inconsistent across state and federal agencies because data are …

Climate Change Adaptation In The Delta Nile Region Of Egypt: Implications For Agricultural Extension, Hazem S. Kassem, Abdel Raouf Suleiman Bello, Bader M. Alotaibi, Fahd O. Aldosri, Gary S. Straquadine

Extension Research

This study used quantitative and qualitative methods to collect data, using questionnaires and interviews, from 792 randomly-selected farmers in two of the governorates in the Nile Delta Region, Egypt. A workshop was organized for 59 extension professionals working in the two governorates, looking at how the adaptive capacity of the agricultural sector towards climate change was being guided by policy-makers. Two focus groups were used: one with senior officials from the regional governorates and the other with central government administrators from the Ministry of Agriculture and Land Reclamation. The study findings suggested that 51.9% of the investigated farmers at the …

Recoupling Fire And Grazing Reduces Wildland Fuel Loads On Rangelands, Heath D. Starns, Samuel D. Fuhlendorf, R. Dwayne Elmore, Dirac Twidwell, Eric T. Thacker, Torre J. Hovick, Barney Luttbeg

Wildland Resources Faculty Publications

Fire suppression and exclusion, the historically dominant paradigm of fire management, has resulted in major modifications of fire-dependent ecosystems worldwide. These changes are partially credited with a recent increase in wildfire number and extent, as well as more extreme fire behavior. Fire and herbivory historically interacted, and research has shown that the interaction creates a unique mosaic of vegetation heterogeneity that each disturbance alone does not create. Because fire and grazing have largely been decoupled in modern times, the degree to which the interaction affects fuels and fire regimes has not yet been quantified. We evaluated effects of fire-only and …

Intensification Of The Decadal Activity In Equatorial Rossby Waves And Linkage To Changing Tropical Circulation, Wan-Ling Tseng, Shih-Yu (Simon) Wang, Huang-Hsiung Hsu, Jonathan D.D. Meyer

Plants, Soils, and Climate Faculty Publications

Equatorial Rossby waves (ERWs) are manifest as westward-propagating, planetary-scale waves that feature a symmetric pair of pressure and zonal wind fields about the equator. ERWs can modulate tropical convective activity, especially in South Asia and the Maritime Continents, and represent an important mode of intraseasonal variability additional to the Madden-Julian Oscillation. Changes in the frequency and intensity of ERWs during the recent decades were investigated based on observations of tropospheric winds and tropical convection. Spectral analyses indicated that ERWs appear to have intensified especially in the upper troposphere; this is associated with increased convective activity located off the equator. The …

Concept Inventories As A Resource For Teaching Evolution, Robert E. Furrow, Jeremy L. Hsu

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Understanding evolution is critical to learning biology, but few college instructors take advantage of the body of peer-reviewed literature that can inform evolution teaching and assessment. Here we summarize the peer-reviewed papers on tools to assess student learning of evolutionary concepts. These published concept inventories provide a resource for instructors to design courses, gauge student preparation, identify key misconceptions in their student population, and measure the impact of a lesson, course, or broader curriculum on student learning. Because these inventories vary in their format, target audience, and degree of validation, we outline and explain these features. In addition to summarizing …

Perceptions Of Risk Of Health Disparities Amid Previously Identified Political Corruption And Ageism In Slovakia, Marta N. Lukacovic, Deborah D. Sellnow-Richmond, Monika Durechova

International Crisis and Risk Communication Conference

This study examines the role of traditional versus new media’s impact on citizens’ perceptions of risk within elder care. We analyzed survey data from 112 Slovak citizens regarding their social network activity and perceptions of corruption, ageism, and health disparities in the Slovak elder care system. Previous research (Lukacovic, Sellnow-Richmond, & Durechova, under contract) identified three prominent sociopolitical issues present in the Slovak medical system among Slovak UGC discourse regarding Slovak healthcare inequity: corruption, threats to dignity, and discrimination. Here, we examined the extent to which social media users perceive the prevalence and subsequent risk of experiencing health disparities within …

The Match-Play Sprint Performance Of Elite Senior Hurlers During Competitive Games, Damien Young, Giuseppe Coratella, Shane Malone, Kieran Collins, Laurent Mourot, Marco Beato

Articles

The typical sprint profile in elite hurling has yet to be established. The purpose of this study was to investigate the sprinting demands of elite hurling competition and characterize the sprinting patterns of different playing positions. GPS (10-Hz, STATSports Viper) were used to collect data from 51 hurlers during 18 games. The total sprint (≥22 km·h^-1) distance (TSD), the number of sprints (NOS) classified as length (<20 >m, ≥20 m) and relative speed thresholds (90%), the between-sprint duration and the number of repeated-sprint bouts (≥2 sprints in ≤60 s) were analyzed. The NOS was 22.2 ± 6.8 accumulating …

Oneness In Everyday Life: Nonduality, Wholeness And Human Life After Awakening, Gibbons, Tom

CONSCIOUSNESS: Ideas and Research for the Twenty-First Century

In Advaita Vedanta a distinction is made between an experience of oneness and permanent awakening. The author argues that a nondual philosophy such as Advaita - as opposed to a direct experience of oneness – contains significant theoretical difficulties, which in turn are reflected in problems with actualizing nonduality in everyday human life. Alternative spiritual conceptions that might be more helpful in guiding the nondual aspirant in her spiritual life are examined, including the concept of “wholeness.” In the place of a reliance on an exclusive doctrine of nonduality, Jorge Ferrar’s concept of “Participatory Spirituality” and A. H. Almaas’s idea …

Categorical Modelling Of Conscious States, Baruss, Imants

CONSCIOUSNESS: Ideas and Research for the Twenty-First Century

In the last several decades, there has been an explosion of research concerning consciousness with some efforts at mathematical modelling. The purpose of this paper is to model conscious states using categorical constructions. In particular, this modelling captures temporality, the intentional structure of consciousness, and meaning fields, which provide the templates for occurrent events. The architecture of conscious states naturally lends itself to applications of category theory, more specifically to sheaf-like constructions in which the stacks over a site are topoi whose germs are the objects of the topoi. Each topos represents the potential experiential content of an individual where …

Psychotherapy In The Dream: A Phenomenological Exploration, Bustos, Nick

CONSCIOUSNESS: Ideas and Research for the Twenty-First Century

Post-materialist ontologies offer a transformed worldview whose implications point toward the illusory nature of the separate self, or ego. Aligned with the literature of mysticism and perennialist spiritual models, this portends a significantly altered backdrop for the practice and discipline of psychotherapy, the underlying premises of which assume a strict existential dichotomy between patient and therapist. Kenneth Wapnick, preeminent scholar of the twentieth-century spiritual document of A Course in Miracles, provides a relevant model toward integrating spiritually-based, ego-negative states within psychotherapy practice. The author studied the lived experiences of eight psychotherapists, both practicing and retired, who practice according to this …

Ecopedagogy: Learning How To Participate In Ecological Consciousness, Peterson, Eric

CONSCIOUSNESS: Ideas and Research for the Twenty-First Century

This paper is the result of an inquiry into ecological consciousness through a participatory paradigm. The dialectical relationship between institutionalized education and consciousness is central to this inquiry’s focus. This exploration into ecological consciousness has lead to the following question: How can institutionalized education be designed, delivered, and experienced in a way that nurtures ecological intelligence, ecological consciousness, and more importantly, ecological activism? The ‘sense of self ‘is a central theme within the paper, and led to the conception of intraearthal and interearthal relationships as a way of communicating our need to identify as being in Earth. The author utilizes …

Defending Behavior Of Peer Victimization In School And Cyber Context During Childhood And Adolescence: A Meta-Analytic Review Of Individual And Peer-Relational Characteristics, Ting-Lan Ma, Diana J. Meter, Wei-Ting Chen, Yen Lee

Human Development and Family Studies Faculty Publications

Adolescent defending of peer victimization in the school and cyber context has received increased attention in developmental science and is an important component of antibullying interventions. However, the overall prevalence, and individual characteristics that correlate with defending in adolescence, have not been systematically and statistically reviewed. Framed in Bronfenbrenner’s social-ecological theory, this meta-analytic review included 172 reports out of 155 studies of defending including 150,978 children and adolescent participants from 4 continents (i.e., North America, Europe, Asia, and Australia) to analyze two aspects: (1) the average proportion of defenders in the population and (2) associations between defending and individual and …

Metabolic Power In Hurling With Respect To Position And Halves Of Match-Play, Damien Young, Shane Malone, Kieran Collins, Laurent Mourot, Marco Beato, Giuseppe Coratella

Articles

The current investigation compared the metabolic power and energetic characteristics in team sports with respect to positional lines and halves of match-play. Global positioning system (GPS) technology data were collected from 22 elite competitive hurling matches over a 3-season period. A total of 250 complete match-files were recorded with players split into positional groups of full-back; half-back; midfield; half-forward; full-forward. Raw GPS data were exported into a customized spreadsheet that provided estimations of metabolic power and speed variables across match-play events (average metabolic power [Pmet], high metabolic load distance [HMLD], total distance, relative distance, high-speed distance, maximal speed, accelerations, and …

Detection Of Adsorbed Chlordecone On Microplastics In Marine Sediments In Guadeloupe: A Preliminary Study, Fidji Sandre, Charlotte R. Dromard, Karyn Le Menach, Yolande Bouchon-Navaro, Sébastien Cordonnier, Nathalie Tapie, Hélène Budzinski, Claude Bouchon

Gulf and Caribbean Research

Plastic pollution in the oceans is recognized as a worldwide problem. Since the 1950s, the production of plastics has been increasing and the first reports of microplastics (particles < 500 μm) in the marine environment began to appear in the 1970s. These particles represent a growing environmental problem due to their dispersion in seawater and marine organisms. Additionally, microparticles in general can adsorb pollutants that will then become bioavailable to organisms by being desorbed during digestion, which could be an important pathway for the contamination of organisms. In Guadeloupe and Martinique, an organochlorine pesticide called “chlordecone” was used from 1972 to 1993 in banana plantations and this very persistent pollutant contaminates soils, rivers, and coastal marine areas and accumulates in marine foodwebs. To examine these issues, we had two goals: 1) to assess the contamination of marine sediments by microplastics surrounding Guadeloupe; and 2) to determine the ability of microplastics to adsorb chlordecone, as has been demonstrated for other organochlorine pollutants. To do so, marine sediments were collected in triplicate from 12 sites in coral reef environments around the island. Microplastics from each sample were then enumerated by size, color and shape under a binocular microscope. The results indicate that microplastics are found in all the studied sites and that their distribution could be linked to marine currents or proximity to areas of significant human activities (port activities, agglomeration, etc.). Finally, our preliminary results indicated that chlordecone could be adsorbed onto microplastics, with a concentration ranging from 0.00036—0.00173 µg/µg of microfilter.

Dough Properties And Baking Characteristics Of White Bread, As Affected By Addition Of Raw, Germinated And Toasted Pea Flour, Kim A. Millar, Catherine Barry-Ryan, Roisin Burke, Sinead Mccarthy, Eimear Gallagher

Articles

Thermal and non-thermal processing may alter the structure and improve the techno-functional properties of pulses and pulse flours, increasing their range of applications in protein-enhanced foods. The effects of germination and toasting of yellow peas (Pisum sativum) on flour and dough characteristics were investigated. Wheat flour was substituted with raw, germinated and toasted pea flour (30%). The resulting bread-baking properties were assessed. Toasting increased dough water absorption and improved dough stability compared with germinated and raw pea flour (p < 0.05). This resulted in bread loaves with comparable specific volume and loaf density to that of a wheat flour control. Significant correlations between dough rheological properties and loaf characteristics were observed. Addition of pea flours increased the protein content of the breads from 8.4% in the control white bread, to 10.1–10.8% (p < 0.001). Toasting demonstrated the potential to improve the techno-functional properties of pea flour. Results highlight the potential application of pea flour in bread-making to increase the protein content.

Exhibit Panels

When people talk about the future of Appalachia, they typically mean economic futures: What will happen to coal jobs? How will Appalachia diversify its economy? What about poverty? Stereotypes about our region represent our people as disinterested in education, and hostile to innovation, technology, and sustainability. We see a different story. This part of the exhibit looks at ways that Appalachians are taking their strong sense of culture, their linguistic distinctiveness, and their relationship to the natural world to imagine new futures in diverse industries, sustainable practices, and stronger education systems.

Temporal Trends In Florida Panther Food Habits, Gretchen Caudill, David P. Onorato, Mark W. Cunningham, Danny Caudill, Erin H. Leone, Lisa M. Smith, Deborah Jansen

Human–Wildlife Interactions

Once on the brink of extinction, the Florida panther (Puma concolor coryi) has reoccupied parts of its extirpated range in southern Florida, USA over the past 20 years, which has largely been attributed to genetic restoration efforts initiated in 1995 to combat inbreeding depression and subsequent deleterious traits. Concurrent to the resurgence, an increase in documented livestock depredation events has heightened concern over human– panther conflicts. We examined 312 stomach content, scat, and feces (large intestine contents) samples collected 1989 to 2014 across the endemic range in southern Florida. We compared frequency of occurrence of prey items in …

The Impact Of Flexibility On Balance In Rifle Athletes, Ileia Nagelkirk

Williams Honors College, Honors Research Projects

Research has shown that there may be a connection between flexibility and balance when evaluating fall risk in older adults and flexibility’s effect on a balance test (Emilio, Hita-Contreras, Jiménez-Lara, Latorre-Román, & Martínez-Amat, 2014); Overmoyer & Reiser, (2015). Balance is an important component of many sport movements, and has been shown to be particularly important in shooting performance in both novice and Olympic rifle athletes (Mononen, Konttinen, Viitasalo, Era, 2007; Ball, Best, Wrigley, 2003). The purpose of this study was to find if there was a relationship between a rifle athlete’s flexibility and their balance ability, to determine if flexibility …

Assessment Of The Effects Of Climate Change On Evapotranspiration With An Improved Elasticity Method In A Nonhumid Area, Lei Tian, Jiming Jin, Pute Wu, Guo-Yue Niu

Watershed Sciences Faculty Publications

Climatic elasticity is a crucial metric to assess the hydrological influence of climate change. Based on the Budyko equation, this study performed an analytical derivation of the climatic elasticity of evapotranspiration (ET). With this derived elasticity, it is possible to quantitatively separate the impacts of precipitation, air temperature, net radiation, relative humidity, and wind speed on ET in a watershed. This method was applied in the Wuding River Watershed (WRW), located in the center of the Yellow River Watershed of China. The estimated rate of change in ET caused by climatic variables is −10.69 mm/decade, which is close to the …

Quantifying The Impact Of Climate Change And Human Activities On Streamflow In A Semi-Arid Watershed With The Budyko Equation Incorporating Dynamic Vegetation Information, Lei Tian, Jiming Jin, Pute Wu, Guo-Yue Niu

Watershed Sciences Faculty Publications

Understanding hydrological responses to climate change and land use and land cover change (LULCC) is important for water resource planning and management, especially for water-limited areas. The annual streamflow of the Wuding River Watershed (WRW), the largest sediment source of the Yellow River in China, has decreased significantly over the past 50 years at a rate of 5.2 mm/decade. Using the Budyko equation, this study investigated this decrease with the contributions from climate change and LULCC caused by human activities, which have intensified since 1999 due to China’s Grain for Green Project (GFGP). The Budyko parameter that represents watershed characteristics …

Motivations And Satisfaction Of North Dakota Deer Hunters During A Temporal Decline In Deer Populations, Kristen E. Black, William F. Jensen, Robert Newman, Jason Boulanger

Biology Faculty Publications

Achieving state wildlife agency biological goals for deer (Odocoileus spp.) management may often conflict with hunter desires. Concomitantly, better information is needed to optimize agency deer herd management goals with hunters’ social goals. In 2016, we surveyed 3,000 North Dakota, USA, resident deer hunters using a self-administered mail survey to gain a better understanding of motivations, satisfaction, and hunter demographics that may be used to inform hunter recruitment and retention (HRR) efforts during a period of reduced statewide deer populations. With deer-gun license availability strictly limited, we explored the possibility that some gun hunters may have been engaging …

Engineered Coating Of Natural Fibers And Oil-Water Interfaces With Self-Assembly Of Clay Nanotubes, Abhishek Panchal

Doctoral Dissertations

Taking into consideration two different types of surfaces, this dissertation proposes techniques to coat the surface of natural fibers and oil-water interfaces by spontaneous self-assembly of halloysite clay nanotubes. The material of choice, halloysite clay, is a widely available natural resource and can be used after minimal processing. In regards to chemical composition, halloysite clay resembles aluminosilicate mineral kaolin; physically, a defect in the crystal structure ordering causes the sheets of kaolinite to roll into halloysite nanotubes. The dimensions of halloysite nanotubes are dependent on the source, but generally vary from 200 nm to 3 µm in length, 100-150 nm …

Watershed Sciences Faculty Publications

Fifty years ago, riparian habitats were not recognized for their extensive and critical contributions to wildlife and the ecosystem function of watersheds. This changed as riparian values were identified and documented, and the science of riparian ecology developed steadily. Papers in this volume range from the more mesic northwestern United States to the arid Southwest and Mexico. More than two dozen authors—most with decades of experience—review the origins of riparian science in the western United States, document what is currently known about riparian ecosystems, and project future needs. Topics are widespread and include: interactions with fire, climate change, and declining …

When Strange Bedfellows Go All In: A Template For Implementing Non-Lethal Strategies Aimed At Reducing Carnivore Predation Of Livestock, Julie K. Young, John Steuber, Alexandra Few, Adam Baca, Zack Strong

Wildland Resources Faculty Publications

In the Rocky Mountains of the USA, abundances and distributions of grizzly bear Ursus arctos and gray wolf Canis lupus have increased (Bangs et al., 2001; Nicholson & Hendricks, 2018). This has led to increased predation of livestock in areas where livestock producers have not needed to implement conflict prevention methods in recent history. Lethal removal of carnivores that kill livestock remains a common source of carnivore mortalities (Woodroffe, 2001; Broekhuis, Cushman & Elliot, 2017). In the USA, the U.S. Department of Agriculture’s Wildlife Services (USDA-WS) is often asked by the U.S. Fish and Wildlife Service or a State’s wildlife …

Landscape Heterogeneity Strengthens The Relationship Between Β-Diversity And Ecosystem Function, Edd Hammill, Charles P. Hawkins, Hamish S. Greig, Pavel Kratina, Johathan B. Shurin, Trisha Brooke Atwood

Watershed Sciences Faculty Publications

Consensus has emerged in the literature that increased biodiversity enhances the capacity of ecosystems to perform multiple functions. However, most biodiversity/ecosystem function studies focus on a single ecosystem, or on landscapes of homogenous ecosystems. Here, we investigate how increased landscape‐level environmental dissimilarity may affect the relationship between different metrics of diversity (α, β, or γ) and ecosystem function. We produced a suite of simulated landscapes, each of which contained four experimental outdoor aquatic mesocosms. Differences in temperature and nutrient conditions of the mesocosms allowed us to simulate landscapes containing a range of within‐landscape environmental heterogeneities. We found that the variation …
