Herbivory In A Low Arctic Wetland Alters Intraspecific Plant Root Traits With Consequences For Carbon And Nitrogen Cycling, Emily A. Chavez, Jaron Adkins, Bonnie G. Waring, Karen H. Beard, Ryan T. Choi, Lindsay Miller, Taylor Saunders, Trisha B. Atwood

Wildland Resources Faculty Publications

1. High latitude wetlands are ecologically important ecosystems due to their large carbon (C) storage capacity and because they serve as breeding and nesting habitat for large populations of migratory birds. Goose herbivory in wetland meadows affects leaf chemical and morphological traits and also influences soil properties by increasing soil temperature and depositing faeces. Grazing-induced changes to above-ground traits and soil properties impact C cycling, but the influence of grazing on root-mediated C and nitrogen (N) cycling has not been explored.

2. We investigated how goose herbivory in a low-Arctic coastal wetland in western Alaska affected root morphological, physiological and chemical traits …

Evidence Of Substorm-Driven Penetration Electric Field Contributions To Low-Latitude Phenomena: Enhanced Upward Drifts, Plasma Bubble Development And Severe Scintillation, J. Sousasantos, F. S. Rodrigues, B. G. Fejer, R. W. Eastes, A. O. Moraes

All Physics Faculty Publications

In this work, it is demonstrated that substorm-driven penetration electric fields can efficiently enhance the upward plasma transport, favoring the development and structuring of plasma irregularities and the occurrence of scintillation on L-band signals. While most previous studies focus on investigating penetration electric fields during intense geomagnetic storms, here, the period used (April 01–05, 2020) was under very mild geomagnetic activity (−27 nT ≤ SYM-H ≤ 6 nT), so that interplanetary and disturbance dynamo contributions are minimized. This period comprised the same seasonal and solar flux conditions, while undergoing multiple short-lived substorms, making it well-suited to evaluate unequivocally: (a) to …

A Checklist Of The Bees Of Utah, Joseph S. Wilson, Anthony Hunsaker, Terry L. Griswold, Olivia Messinger Carril

Biology Faculty Publications

Understanding bee distributions is essential to protecting these vital pollinators. Since conservation efforts and policies are often made at the state level, maintaining state-specific bee species lists can aid conservationists and policy makers. While several North American state- and province-level bee species lists have been published, few exist for the arid western states, where bee diversity tends to be higher. Here we provide a bee species list for Utah, compiled from online occurrence records from the Symbiota Collection of Arthropods Network (SCAN) and specimen records housed in the USDA-ARS Pollinating Insect Research Unit (BBSL). In total we document 1167 bee …

Continuous Exposure To An Aversive Mixture: A Means Of Maintaining Aversion In Sheep Averted To Geigeria Ornativa O. Hoffm. (Vermeerbos) - An Assessment, Leendert D. Snyman

Poisonous Plant Research (PPR)

Establishing aversion to Geigeria ornativa only lasts for some time, after which the induced aversion disappears and sheep start eating G. ornativa again. This behavior is aggravated by the social influence of non-averted sheep in mixed grazing situations. Exposing sheep continuously to a so-called “aversive mixture”, containing an aversive substance (lithium chloride) and the sensory characteristics of the plant (hexane extract of G. ornativa) mixed with a tasty meal (maize meal), following an initial aversion treatment, resulted in sustained aversion to G. ornativa in the field. This method proved to be applicable to mixed grazing situations with averted and …

Psychosocial And Audiological Characteristics In Misophonia: An Interdisciplinary Comparison Study Of Adults With Misophonia To Healthy Controls, Mercedes G. Woolley, Hailey E. Johnson, Emily M. Bowers, Doris Velasquez, Julie M. Petersen, Karen Muñoz, Michael P. Twohig

Psychology Student Research

Despite the increasing investigation into misophonia, its classification remains debated due to symptom overlap with audiological and psychological conditions, as well as methodological limitations in existing studies. In the present study, we compared a clinical sample of adults seeking treatment for misophonia with a non-treatment-seeking sample of age- and gender-matched healthy controls. In these two samples, we examined the psychological and audiological features of misophonia by assessing key psychological processes (anger, disgust, OCD symptoms, anxiety, depression, stress, wellbeing, and psychological inflexibility) and audiological features (hearing, hyperacusis, and tinnitus). We found that individuals with misophonia exhibit higher levels of psychological inflexibility …

Leveraging High-Frequency Sensor Data And U.S. National Water Model Output To Forecast Turbidity In A Drinking Water Supply Basin, John T. Kemper, Kristen L. Underwood, Scott D. Hamshaw, Dany Davis, Jason Siemion, James B. Shanley, Andrew W. Schroth

Watershed Sciences Faculty Publications

As high-frequency sensor networks increasingly enhance data-driven models of water quality, process-based models like the U.S. National Water Model (NWM) are generating accessible forecasts of streamflow at increasingly dense scales. There is now an opportunity to combine these products to construct actionable water quality forecasts. To that end, we couple streamflow forecasts from the NWM to a gradient-boosted decision tree algorithm (LightGBM) trained on 5+ years of high-frequency monitoring data to forecast in-stream turbidity levels in the Catskill Mountains, NY, USA. Results indicate LightGBM models are capable of relatively skillful predictions, which enable robust forecasts for 1–3 days lead times. …

To this end, we first conducted a preliminary study to translate the participants’ feedback into improving our initial designs, followed by a lab study with 20 participants (60% Male, 40% Female; 18-44 years old) aimed at understanding their perceptions of the improved interventions; we further updated our …

Toward A Construct-Based Definition Of Urban Green Space: A Literature Review Of The Spatial Dimensions Of Measurement, Methods, And Exposure, Doo Hong Lee, Brent Chamberlain, Hye Yeon Park

Landscape Architecture and Environmental Planning Student Research

Interdisciplinary research has significantly advanced our understanding, benefits, and measurements of Urban Green Space (UGS). Further, the rapid expansion of research on this topic has resulted in a diverse array of definitions, which can rely on implicit assumptions without a formal definition. This variability highlights the need for a carefully structured framework to refine and combine these definitions. This narrative review examines constructs underlying UGS, particularly focusing on the spatial aspects of how we spatially measure UGS, the measurements of UGS, and how we define exposure; the latter focuses on two methods: viewsheds and image segmentation. Our findings reveal a …

Wild Licorice (Glycyrrhiza Lepidota) Identification And Management In Pastures, Jacob Hadfield, Taun Beddes, Michael Caron, Corey Ransom

All Current Publications

Wild licorice, also known as American licorice, is a perennial legume native to North America, commonly found in the western United States. Wild licorice reproduces rapidly through seeds and rhizomes, leading to large infestations, particularly in pastures. The low preference of livestock for wild licorice results in overgrazing of other plant species, leaving them at a competitive disadvantage, further promoting the spread of wild licorice and contributing to pasture infestations. This fact sheet reviews the identification and management of wild licorice in pastures.
