Cattle Toxicity From Woolly Locoweed (Astragalus Mollissimus): A Case Study In Central New Mexico, Casey N. Spackman, Clint A. Stonecipher, Daniel Cook

Poisonous Plant Research (PPR)

Livestock toxicity resulting from poisonous plants poses a significant challenge for ranchers, particularly concerning locoweeds (Astragalus spp. or Oxytropis spp.). This study investigated a case of cattle poisoning in central New Mexico, where clinical signs were consistent with locoweed toxicity. Rangeland conditions were hot and dry following earlier spring rains, promoting advantageous environmental conditions for a locoweed outbreak. Analysis of Woolly locoweed (Astragalus mollissimus) and animal samples from the ranch confirmed the presence of swainsonine, a key toxin in locoweeds. It can be concluded that the likely cause of cattle losses was locoweed toxicity, highlighting the …

Supplementary Files For "Using Digitized Building And Weather Records To Improve The Accuracy Of Ground To Roof Snow Load Ratio Estimations", Gideon Parry, Brennan Bean

Browse all Datasets

Reliability targeted snow loads (RTLs) measure the weight in accumulated snow (i.e. snow load) that a roof is required to support to ensure the probability of failure is suf- ficiently low. This calculation has historically relied upon a probability distribution that characterizes the ratio between the annual maximum ground snow load to the annual max- imum roof snow load, a quantity referred to as Gr. The best available data for estimating Gr comes from Canadian case studies from the 1950s and 1960s. However, much of the data was never digitized, with only approximations of data being made available in scanned …

Development And Validation Of A High School Agricultural Literacy Assessment, Rose Judd-Murray, Brian K. Warnick, Daniel C. Coster, Max L. Longhurst

Teacher Education and Leadership Faculty Publications

The National Agricultural Literacy Outcomes (NALOs) are knowledge benchmarks for school-aged youth and are used to improve agricultural literacy (National Agriculture in the Classroom, 2014; National Center for Agricultural Literacy, 2017). Despite educational efforts, prior research indicated that high school populations remained at low or deficient literacy levels. Additionally, no agricultural literacy assessment instruments using the NALOs as a standardization benchmark have been developed for the 9-12th grades. The purpose of the study was to validate a summative NALO-centered assessment that could provide baseline data on agricultural literacy following the completion of secondary education (12th grade). The study followed the …

Theory-Based Science Communication At Comic Cons, Lisa Lundgren, Emily Slater, Man Zhang, Kadie Kunz, Gabriel-Philip Santos

Instructional Technology and Learning Sciences Faculty Publications

The majority of research concerning science communication happens in spaces where people already have a vested interest in or knowledge of science, such as museums and science cafes. Thus, there is a gap in understanding what theory-based science communication looks like in non-science-centered spaces. This qualitative research study, which featured cosplaying science communicators at comic conventions, offers insights into what science communication practices occur within everyday spaces. We conducted observations of and semi-structured interviews with 15 cosplaying scientists, examining how they utilized effective framing and narrative structuring when communicating science at comic cons in cosplay. Across 700 coded utterances, cosplaying …

Who Gets To Decolonize: A Reflection On The Importance Of Positionality In The Decolonization Of Digital Learning Spaces And Learning Design, Rebecca Y. Bayeck, Tutaleni Iita Asino

Instructional Technology and Learning Sciences Faculty Publications

Decolonization as a term and concept gained prominence in the 20th century as new nations emerged from the cessation of the global colonial project which primarily saw European countries occupying different parts of the world. In modern times, interests in decolonization have taken different forms, particularly in learning design and digital learning spaces. In the digital space, researchers mainly suggest introducing indigenous perspectives and cultural lenses in the design of digital learning environments and the design of emerging technologies that embed indigenous perspectives (Nede, 2023). This reflexive essay discusses the importance of positionality in digital learning spaces and learning/instructional design. …

Soil test correlation determines whether a soil test can be used to predict the need for fertilization based on the critical soil test value (CSTV). Our objectives were to compare the CSTV estimated from five combinations of correlation models and yield sufficiency interpretations and to select one method for soil test correlation performed with the Fertilizer Recommendation Support Tool (FRST). Four models were fit to three datasets with strong (Mehlich-1 K), moderate (Mehlich-3 K), or weak (Olsen P) correlations between soil test P or K and crop relative yield. We tested the arcsine-log calibration curve (ALCC), exponential (EXP), linear plateau …

A New Generation Of Collecting Priorities: Case Studies From The Northwest, Jodi Allison-Bunnell, Linda Long, Trevor J. Bond, Chloe Nielsen, Amy Valentine

Journal of Western Archives

The last twenty-five years have brought lively, important, and difficult discussions around heritage collections. We are called to broaden our collecting activities to be more inclusive of (among many things) all races, classes, and experiences. We have begun to move away from the troubled legacy of taking collections away from creators and toward empowering those same creators to steward their heritage. We confront a vast universe of current holdings and possible collections and have few models for assessing the opportunities. We also operate with some firm limitations on our budgets, personnel, and space that we have outdistanced with our collecting. …

Plasma RNAemia, delayed antibody responses and inflammation predict COVID-19 outcomes, but the mechanisms underlying these immunovirological patterns are poorly understood. We profile 782 longitudinal plasma samples from 318 hospitalized patients with COVID-19. Integrated analysis using k-means reveals four patient clusters in a discovery cohort: mechanically ventilated critically-ill cases are subdivided into good prognosis and high-fatality clusters (reproduced in a validation cohort), while non-critical survivors segregate into high and low early antibody responders. Only the high-fatality cluster is enriched for transcriptomic signatures associated with COVID-19 severity, and each cluster has distinct RBD-specific antibody elicitation kinetics. Both critical and non-critical clusters with …

Temporal And Spatial Influences On Fawn Summer Survival In Pronghorn Populations: Management Implications From Noninvasive Monitoring, Cole A. Bleke, Eric M. Gese, Juan J. Villalba, Shane B. Roberts, Susannah S. French

Wildland Resources Student Research

Monitoring vital rates allows managers to estimate trends in growth rates of ungulate populations. However, connecting the influence of nutrition on ungulate demography is challenging. Noninvasive sampling offers a low-cost, low-effort alternative for measuring nutritional indices, allowing for an increased understanding of the mechanistic relationships between environmental factors, nutrition, and specific population vital rates. We examined the temporal influence of intrinsic and extrinsic factors on pronghorn (Antilocapra americana) fawn recruitment. We collected fresh fecal samples from adult female pronghorn in five subpopulations spanning three sampling periods associated with critical maternal life-history stages (late gestation, early lactation, breeding season) …

Resurgence Of Destructive Behavior Following Decreases In Alternative Reinforcement: A Prospective Analysis, Brian D. Greer, Timothy A. Shahan, Casey Irwin Helvey, Wayne W. Fisher, Daniel R. Mitteer, Ashley M. Fuhrman

Psychology Faculty Publications

Basic and retrospective translational research has shown that the magnitude of resurgence is determined by the size of the decrease in alternative reinforcement, with larger decreases producing more resurgence. However, this finding has not been evaluated prospectively with a clinical population. In Experiment 1, five participants experienced a fixed progression of reinforcement schedule-thinning steps during treatment of their destructive behavior. Resurgence occurred infrequently across steps and participants, and when resurgence did occur, its clinical meaningfulness was often minimal. In Experiment 2, five new participants experienced these same schedule-thinning steps but in a counterbalanced order. Resurgence occurred most often and was …

Landscape Influences On Thermal Sensitivity And Predicted Spatial Variability Among Brook Trout Streams In The Southeastern Usa, George P. Valentine, Xinyi Lu, C. Andrew Dolloff, Craig N. Roghair, Jacob M. Rash, Mevin B. Hooten, Yoichiro Kanno

Mathematics and Statistics Faculty Publications

Warming water temperatures as a result of climate change pose a major threat to coldwater organisms. However, the rate of warming is not spatially uniform due to surface-ground-water interactions and stream and watershed characteristics. Coldwater habitats that are most resistant to warming serve as thermal refugia and identifying their locations is critical to regional aquatic conservation planning. We quantified the thermal sensitivity of 203 streams providing current and potential habitat for brook trout (Salvelinus fontinalis) across nearly 1000 linear km of their native range in the southern and central Appalachian Mountains region, USA, and characterized their spatial variability …
