Archaeological Analysis Of Bison Remains From Wilde Cave, Idaho, Michelle Platt

Student Research Symposium

In October of 2017 a small crew of students excavated Wilde Cave. The floor of this lava tube located in Idaho was littered with hundreds of faunal samples. As an Honors Capstone Research Project the bone remains were collected and analyzed. We spent two days collecting the samples along with their coordinates. Returning to USU, the osteological specimens were cleaned, labeled, identified, and cataloged. Following the completion of identifying and cataloging, the information was analyzed to understand the statistical relationships between the specimens.

Every Day Monuments: A Restoration & Style Guide For Cache ValleyʼS Historic Residential Architecture, Jonathan Skyler Tippetts

Student Research Symposium

Picturesque tree lined streets, and the eclectic mingling of architectural styles from a bygone era are what draw many people to historic districts and vintage suburbs across the nation. As one tours these old neighborhoods, one can find a vast expanse of historic architectural styles ranging from exuberantly decorated Victorians, to Craftsman Bungalows and the emergence of modernism. Great lengths have been put into place to protect architectural landmarks built for historically prominent people, or properties designed by influential architects. But what about the quaint Gothic Revival cottage built for the dress maker, the local bakers foursquare on Center Street, …

Speak And Sketch: Improving Academic Language Through Note-Taking And Verbal Rehearsal, Rj Risueño

Student Research Symposium

Students in later elementary grades must understand informational texts, extract and synthesize critical ideas and details, and apply that information in tests, reports, and projects. This case study is a follow-up to a larger treatment study. The modifications in the case study focus on increased verbal rehearsal and coaching over a longer treatment time. One sixth and two fourth graders with language impairment participated. The speak-and-sketch treatment involved repeated practice with two notation forms, pictography and bulleted notes; and presentation practice of well-formed sentences and reports. Treatment was delivered in two 20-minute sessions a week over eight weeks by the …

Stocks Or Stakeholders: Nonhuman Animals In Natural Resource Sociology, Michael Briscoe

Student Research Symposium

Human values and meanings for nonhuman animals are socially constructed. Nonhuman animals provide value through tangible means, such as food or economic value, but they also are valued for providing experiences, symbols, and ecosystem services like diversity. Nonhuman animals are afforded certain rights and considerations in modern society, but these have proved insufficient in ensuring positive outcomes for both social and ecological systems. Considering nonhuman animals as stakeholders could improve natural resource outcomes by more fully addressing transboundary and uncertainty issues.

Phenological Mismatch In Coastal Western Alaska May Increase Summer Season Greenhouse Gas Uptake, Katharine C. Kelsey, A. Joshua Leffler, Karen H. Beard, Ryan T. Choi, Joel A. Schmutz, Jeffery M. Welker

Wildland Resources Faculty Publications

High latitude ecosystems are prone to phenological mismatches due to climate change- driven advances in the growing season and changing arrival times of migratory herbivores. These changes have the potential to alter biogeochemical cycling and contribute to feedbacks on climate change by altering greenhouse gas (GHG) emissions of carbon dioxide (CO₂), methane (CH₄) and nitrous oxide (N₂O) through large regions of the Arctic. Yet the effects of phenological mismatches on gas fluxes are currently unexplored. We used a three-year field experiment that altered the start of the growing season and timing of grazing to …

Banning Furs And Plastics: Vital Progress Of Unjust Restriction Of Liberty?, Rachel Robinson-Greene

Languages, Philosophy, and Communication Studies Faculty Publications

It is easy to forget that our choices as consumers have significant consequences beyond satisfying our material needs or desires. Many of us make purchasing choices with little regard for how those choices affect other people, non-human animals, or the environment. In many cases, the stakes are tragically high. One proposal worth consideration, then, is that certain purchasing options should simply be off the table or should, at a minimum, be highly regulated.

Syringomyelia In An Adult American Paint Horse, Jacqueline P. Kurz, Kate E. Schoenhals, Gordon A. Hullinger, Arnaud J. Van Wettere

Animal, Dairy, and Veterinary Science Faculty Publications

Syringomyelia is a form of myelodysplasia defined by the formation of one or more fluid-filled cavities within the spinal cord that do not communicate with the central canal. The defect may be congenital or acquired. Clinical signs correlate to the segment of spinal cord affected and include pain, paresis, proprioceptive deficits, alterations in sensation, scoliosis, and autonomic dysfunction. This report describes the clinical and pathologic changes in a case of acquired syringomyelia in a 10-year-old American Paint Horse mare. The horse had a six-week history of progressive proprioceptive deficits in all four limbs, bilateral pelvic limb ataxia, and muscle fasciculations …

Routes Of Pesticide Exposure In Solitary, Cavity-Nesting Bees, Andi M. Kopit, Theresa L. Pitts-Singer

Biology Faculty Publications

Declines of pollinator health and their populations continue to be commercial and ecological concerns. Agricultural practices, such as the use of agrochemicals, are among factors attributed to honey bee (Apis mellifera L. (Hymenoptera: Apidae)) population losses and are also known to have negative effects on populations of managed non-Apis pollinators. Although pesticide registration routinely requires evaluation of impacts on honey bees, studies of this social species may not reveal important pesticide exposure routes where managed, solitary bees are commonly used. Studies of solitary bees offer additional bee models that are practical from the aspect of availability, known rearing …

Should Chimpanzees Be Granted Legal Personhood?, Rachel Robinson-Greene

Languages, Philosophy, and Communication Studies Faculty Publications

In recent years, advocates for animal welfare have pursued legal rights for animals in the courts. Tommy and Kiko are chimpanzees who were once famous for their appearance in Hollywood films. Both now live in captivity in small cages—conditions that are far from optimal relative to what a flourishing life for a chimpanzee would look like. Hercules and Leo are chimpanzees who have been the subject of invasive medical research and experimentation for their entire lives, nearly a decade. Advocates for these animals argue that it is morally wrong to view them as mere property. There should be some legal …

Site Conditions Determine A Key Native Plant’S Contribution To Invasion Resistance In Grasslands, Kristin B. Hulvey, Brittany J. Teller

Wildland Resources Faculty Publications

Many plant invasion studies in grasslands suggest that resident plants that share functional traits with invaders can reduce invasion by competing for limiting resources. However, since invasion studies often occur in highly controlled plots or microcosms, it is unclear how heterogeneous site conditions alter competitive interactions under realistic scenarios. To explore how landscape heterogeneity affects biotic resistance provided by competitive resident plants, we conducted a field‐based experiment across four sites in California grasslands. Plots contained naturally occurring populations of native Hemizonia congesta, but differed in other characteristics, including litter cover, annual grass cover, soil moisture, and species richness. We invaded …

Introducing And Evaluating A Knowledge Transfer Approach To Support Problem Solving In And Around Protected Areas, Brady J. Mattsson, Marie Fischborn, Mark W. Brunson, Harald Vacik

Environment and Society Faculty Publications

Protected areas (PAs) can generate many benefits inside and outside their borders, and achieving objectives for diverse stakeholders raises many challenges. There are many examples of successful PA management around the globe, although a systematic and comprehensive approach to developing and sharing these solutions has been lacking. We present “solutioning” as a structured process of peer-learning, which can inform management strategies in and around protected areas. We explain how the PANORAMA—Solutions for a Healthy Planet initiative has put solutioning into practice through an interactive community and web portal to learn about protected area solutions around the globe. Unlike other web …

Herbivore Removal Reduces Influence Of Arbuscular Mycorrhizal Fungi On Plant Growth And Tolerance In An East African Savanna, Jonathan B. González, Renee H. Petipas, Oscar Franken, E. Toby Kiers, Kari E. Veblen, Alison K. Brody

Wildland Resources Faculty Publications

The functional relationship between arbuscular mycorrhizal fungi (AMF) and their hosts is variable on small spatial scales. Here, we hypothesized that herbivore exclusion changes the AMF community and alters the ability of AMF to enhance plant tolerance to grazing. We grew the perennial bunchgrass, Themeda triandra Forssk in inoculum from soils collected in the Kenya Long-term Exclosure Experiment where treatments representing different levels of herbivory have been in place since 1995. We assessed AMF diversity in the field, using terminal restriction fragment length polymorphism and compared fungal diversity among treatments. We conducted clipping experiments in the greenhouse and field and …

Feasible Conversion Degree Of Dryland To Paddy Field In Jinxian County, Jiangxi Province, China, Dun Yu, R. D. Ramsey, Xiao-Min Zhao, Yong-Qi Fu, Cong-Kang Sun

Wildland Resources Faculty Publications

The purpose of this paper was to evaluate the feasibility of conversion from dryland to paddy field in Jinxian County under the water resources constraint and dryland suitability condition. We constructed a water resources balance model to evaluate irrigation needs and a dryland suitability model that coupled various spatial data layers. Our research showed that under the water resources constraint, the amount of conversion from dryland to paddy field was 26,971.69 ha and the feasible conversion degree of dryland to paddy field was 0.84, while under the dryland suitability condition, it was 23,262.74 ha and 0.72, respectively. According to the …

Functional Trait Differences Between Native Bunchgrasses And The Invasive Grass Bromus Tectorum, Huiqin H.E., Thomas A. Monaco, Thomas A. Jones

Forage and Range Research Laboratory Publications

We conducted 30- and 60-d greenhouse experiments to compare functional traits of Bromus tectorum (invasive annual grass) and four perennial bunchgrasses under well-watered or drought conditions. Even under drought, B. tectorum experienced significantly less stress (i.e., higher xylem pressure potential and greater shoot water content, water use per day and water-use efficiency) and biomass production than the perennial grasses after 30 d. However, after 60 d, its superiority was reduced under infrequent watering. Differences among perennial grasses were more pronounced for physiological traits under infrequent watering and for morphological traits under frequent watering. Elymus multisetus (fastgrowing species) had a higher …

Influence Of Harvest Date On Seed Yield And Quality In Forage Kochia, Cody F. Creech, Blair L. Waldron, Corey V. Ransom, Dale R. Zobell, Joseph Earl Creech

Plants, Soils, and Climate Faculty Publications

Forage kochia (Bassia prostrata) is used for rangeland reclamation and livestock and wildlife forage, but limited research has been conducted on its seed production. Therefore, this research evaluated the effect of harvest date on seed weight, germination, and seed yield of forage kochia subspecies virescens and grisea. Seed was harvested from individual plants for 3 years during October, November, and December. October harvest had the lightest 100-seed weights, with the November harvest slightly heavier than December, for most accessions. Cultivar Snowstorm and breeding line Sahsel, both subsp. grisea, had the greatest 100-seed weights in November, 155 …

Relationships Between Cattle And Biodiversity In Multiuse Landscape Revealed By Kenya Long-Term Exclosure Experiment, Truman P. Young, Lauren M. Porensky, Corinna Riginos, Kari E. Veblen, Wilfred O. Odadi, Duncan M. Kimuyu, Grace K. Charles, Hillary S. Young

Wildland Resources Faculty Publications

On rangelands worldwide, cattle interact with many forms of biodiversity, most obviously with vegetation and other large herbivores. Since 1995, we have been manipulating the presence of cattle, mesoherbivores, and megaherbivores (elephants and giraffes) in a series of eighteen 4-ha (10-acre) plots at the Kenya Long-term Exclosure Experiment. We recently (2013) crossed these treatments with small-scale controlled burns. These replicated experimental treatments simulate different land management practices. We seek to disentangle the complex relationships between livestock and biodiversity in a biome where worldwide, uneasy coexistence is the norm. Here, we synthesize more than 20 yr of data to address three …

The Puppy And The Snapping Turtle, Rachel Robinson-Greene

Languages, Philosophy, and Communication Studies Faculty Publications

On March 8, 2018, an abandoned, terminally ill puppy was brought into the classroom of Idaho high school science teacher Robert Crosland. Crosland, known for taking in sick animals, could tell that the puppy was beyond saving. After school, in front of a handful of his students, Crosland placed the sick puppy inside the tank of his snapping turtle. It drowned and was then eaten by the turtle. Crosland was reported for animal cruelty. The snapping turtle, a member of an invasive species, was confiscated and euthanized by the Department of Agriculture.

Alluvial Substrate Mapping By Automated Texture Segmentation Of Recreational-Grade Side Scan Sonar Imagery, Daniel Hamill, Daniel Buscombe, Joseph Michael Wheaton

Watershed Sciences Faculty Publications

Side scan sonar in low-cost ‘fishfinder’ systems has become popular in aquatic ecology and sedimentology for imaging submerged riverbed sediment at coverages and resolutions sufficient to relate bed texture to grain-size. Traditional methods to map bed texture (i.e. physical samples) are relatively high-cost and low spatial coverage compared to sonar, which can continuously image several kilometers of channel in a few hours. Towards a goal of automating the classification of bed habitat features, we investigate relationships between substrates and statistical descriptors of bed textures in side scan sonar echograms of alluvial deposits. We develop a method for automated segmentation of …

Winter Feeding Of Elk In The Greater Yellowstone Ecosystem And Its Effects On Disease Dynamics, Gavin C. Cotterill, Paul C. Cross, Erik K. Cole, Rebecca K. Fuda, Jared D. Rogerson, Brandon M. Scurlock, Johan T. Du Toit

Wildland Resources Faculty Publications

Providing food to wildlife during periods when natural food is limited results in aggregations that may facilitate disease transmission. This is exemplified in western Wyoming where institutional feeding over the past century has aimed to mitigate wildlife–livestock conflict and minimize winter mortality of elk (Cervus canadensis). Here we review research across 23 winter feedgrounds where the most studied disease is brucellosis, caused by the bacterium Brucella abortus. Traditional veterinary practices (vaccination, test-and-slaughter) have thus far been unable to control this disease in elk, which can spill over to cattle. Current disease-reduction efforts are being guided by ecological …

Plants, Soils, and Climate Faculty Publications

Sustainable intensification is an emerging model for agriculture designed to reconcile accelerating global demand for agricultural products with long-term environmental stewardship. Defined here as increasing agricultural production while maintaining or improving environmental quality, sustainable intensification hinges upon decision-making by agricultural producers, consumers, and policy-makers. The Long-Term Agroecosystem Research (LTAR) network was established to inform these decisions. Here we introduce the LTAR Common Experiment, through which scientists and partnering producers in US croplands, rangelands, and pasturelands are conducting 21 independent but coordinated experiments. Each local effort compares the outcomes of a predominant, conventional production system in the region ('business as usual') …

Restoration Handbook For Sagebrush Steppe Ecosystems With Emphasis On Greater Sage-Grouse Habitat—Part 3. Site Level Restoration Decisions, David A. Pyke, Jeanne C. Chambers, Mike Pellant, Richard F. Miller, Jeffrey L. Beck, Paul S. Doescher, Bruce A. Roundy, Eugene W. Schupp, Steven T. Knick, Mark W. Brunson, James D. Mclver

Reports

Sagebrush steppe ecosystems in the United States currently (2016) occur on only about one-half of their historical land area because of changes in land use, urban growth, and degradation of land, including invasions of non-native plants. The existence of many animal species depends on the existence of sagebrush steppe habitat. The greater sage-grouse (Centrocercus urophasianus) depends on large landscapes of intact habitat of sagebrush and perennial grasses for their existence. In addition, other sagebrush-obligate animals have similar requirements and restoration of landscapes for greater sage-grouse also will benefit these animals. Once sagebrush lands are degraded, they may require …

Monitoring Of Dung Beetle (Scarabaeidae And Geotrupidae) Activity Along Maryland's Coastal Plain, Patrick Simons, Michael Molina, Mallory A. Hagadorn, Dana L. Price

Biology Faculty Publications

Our understanding of how human activities impact insect communities is limited. Dung beetles, well known for the ecosystem services they provide, are faced with many conservation threats, particularly from deforestation and agriculture. Here we used 200-m transects and human-dung—baited pitfall traps to examine dung beetle populations in 7 forests of Maryland's Coastal Plain. We set traps once a month, from May 2014 to April 2015, to determine species presence, abundance, range, and seasonality. We collected 6463 individuals representing 22 species; Janes Island State Park (JISP) had the highest abundance (2705 individuals) and Martinak State Park (MSP) had the highest species …

Domestication fundamentally reshaped animal morphology, physiology and behaviour, offering the opportunity to investigate the molecular processes driving evolutionary change. Here we assess sheep domestication and artificial selection by comparing genome sequence from 43 modern breeds (Ovis aries) and their Asian mouflon ancestor (O. orientalis) to identify selection sweeps. Next, we provide a comparative functional annotation of the sheep genome, validated using experimental ChIP-Seq of sheep tissue. Using these annotations, we evaluate the impact of selection and domestication on regulatory sequences and find that sweeps are significantly enriched for protein coding genes, proximal regulatory elements of genes …
