Managing Water Stored For The Environment During Drought, Sarah Null, Jeffrey Mount, Brian Gray, Michael Dettinger, Kristen Dybala, Gokce Sencan, Anna Sturrock, Barton Thompson, Harrison Zeff

Watershed Sciences Faculty Publications

Storing water in reservoirs is important for maintaining freshwater ecosystem health and protecting native species. Stored water also is essential for adapting to the changing climate, especially warming and drought intensification. Yet, reservoir operators often treat environmental objectives as a constraint, rather than as a priority akin to water deliveries for cities and farms. Reservoir management becomes especially challenging during severe droughts when surface water supplies are scarce, and urban and agricultural demands conflict with water supplies needed to maintain healthy waterways and wetlands. In times of drought, most freshwater ecosystems suffer.

Lindroth + Aspen: A Legacy of Good Chemistry

Ken Keefover-Ring

The license plates on Professor Rick Lindroth’s vehicle read “Q ASPEN,” referring to quaking aspen. This gives you a hint of the extent of his obsession; one he will surely carry into his upcoming retirement. Rick has co-authored almost 220 peer-reviewed articles and 15 book chapters over his academic career and more than 70% of them involve aspen (Populus tremuloides) in some way. In fact, many issues of Tremblings have listed one or more of his papers. This research has largely been focused on aspen chemical ecology and …

Latinx Caregivers’ Perceived Need For And Utilization Of Youth Telepsychology Services During The Coronavirus Pandemic, Alejandro L. Vázquez, Cynthia M. Navarro Flores, María De La Caridad Alvarez, Melanie M. Domenech Rodríguez

Psychology Faculty Publications

Telepsychology has the potential to provide a safe method of addressing mental health problems among Latinx youth during the coronavirus pandemic. However, the extent to which Latinx caregivers are accessing telepsychology services for their child and whether this format is perceived to be an appropriate method of addressing youth psychopathology is unknown. The present study examined indicators of youth psychopathology and external stressors in relation to Latinx caregivers’ perceived need for and utilization of youth telepsychology during the coronavirus pandemic. The sample consisted of 598 Latinx caregivers of school-age youths (MAge = 11.9, SD = 3.4) from across the United …

Biodiversity Scale-Dependence And Opposing Multi-Level Correlations Underlie Differences Among Taxonomic, Phylogenetic And Functional Diversity, Nadejda A. Mirochnitchenko, Erica F. Stuber, Joseph J. Fontaine

Wildland Resources Faculty Publications

Aim

Biodiversity is a multi-dimensional property of biological communities that represents different information depending on how it is measured, but how dimensions relate to one another and under what conditions is not well understood. We explore how taxonomic, phylogenetic, and functional diversity can differ in scale-of-effect dependence and habitat-biodiversity relationships, and subsequently how spatial differences among biodiversity dimensions may arise.

Location

Nebraska, United States.

Taxon

Birds.

Methods

Across 2016 and 2017, we conducted 2,641 point counts at 781 sites. We modeled the occupancy of 141 species using Bayesian Bernoulli-Bernoulli hierarchical logistic regressions. We calculated species richness (SR), phylogenetic diversity (PD) …

Advancing Clinical Practice Through Integration Of Congenital Cytomegalovirus (Ccmv) Testing With Newborn Hearing Screening At Mayo Clinic, Joscelyn R. K. Martin, W. Charles Huskins, Lisa A. Schimmenti, Shelagh A. Cofer, Gayla L. Poling

Journal of Early Hearing Detection and Intervention

Although cCMV is the leading non-genetic cause of childhood hearing loss in the United States, neither targeted nor universal screening protocols have been well established to identify cCMV in newborns. Moreover, until cCMV testing is universal, clinical protocols need to account for the complexities of individualized care in partnership with interprofessional care teams. This work addressed an immediate clinical practice need to identify cCMV with subsequent hearing monitoring of babies who test positive for cCMV. This effort focused on three primary objectives to: 1) define interprofessional, team-based approach to facilitate care pathways; 2) develop a clinical workflow for all babies …

Using Online Genres To Promote Students’ Audience Awareness, Elena Taylor

Journal on Empowering Teaching Excellence

Writing assignments that students complete in university courses are typically designed for evaluation and grading by the instructor, who, therefore, acts as the sole reader of student written work. However, most written genres students would--and do--encounter in the world beyond the classroom are composed for diverse audiences who influence writers’ text construction considerably. Because most students will be likely to write for multiple audiences as part of their career or future academic endeavors, it is crucial for them to develop a sense of audience awareness as an indispensable rhetorical concept that shapes composing processes. Writing online presents a great opportunity …

Pareto Optimality And Compromise For Environmental Water Management, Sarah E. Null, Marcelo A. Olivares, Felipe Cordera, Jay R. Lund

Watershed Sciences Faculty Publications

Water management usually considers economic and ecological objectives, and involves tradeoffs, conflicts, compromise, and cooperation among objectives. Pareto optimality often is championed in water management, but its relationships with the mathematical representation of objectives, and implications of tradeoffs for Pareto optimal decisions, are rarely examined. We evaluate the mathematical properties of optimized tradeoffs to identify promising regions for compromise, suggest strategies for reducing conflicts, and better understand whether decision-makers are more or less likely to cooperate on environmental water allocations. Cooperation and compromise among objectives can be easier when tradeoff curves are concave and more adversarial when tradeoff curves are …

High Value Correlates Of Caregiver Reported Counseling Service Need And Utilization For Adolescents At-Risk For Childhood Maltreatment And Neglect, Alejandro L. Vázquez, Tommy Chou, Cynthia M. Navarro Flores, Tyson S. Barett, Miguel T. Villodas, Melanie M. Domenech Rodríguez

Psychology Faculty Publications

Adolescents with a history of child maltreatment experience increased risk for psychopathology that sets them on a trajectory towards a range of difficulties in adulthood. Various factors influence caregivers’ decisions to seek mental health services (MHS) that could improve developmental outcomes. The present study applied a machine learning algorithm, elastic net, to a sample of 878 adolescent-caregiver dyads from the Longitudinal Studies of Child Abuse and Neglect. Analyses simultaneously examined a large number of factors to determine their ability to discriminate between caregivers who perceived a need for MHS and those who did not, as well as caregivers who utilized …

Teaching Archival Research Methods Through Projects In Ethnohistory, Veronica L. Denison, Alyssa Willett, Alexandra Taitt, Medeia Csoba Dehass

Journal of Western Archives

During the spring semester of 2015 and the fall semester of 2016, two cohorts of students at the University of Alaska Anchorage learned archival research skills as part of their methodological training in the course, Ethnohistory of Alaska Natives, which subsequently led to the development of further individual research projects. As part of the course, students provided metadata to folders within an archival collection. This article explores the semester long projects, including the hardships of finding and using culturally appropriate metadata, lessons learned, and the impact the project had on students, the archivist, and instructor.

Simulated Dynamics Of Mixed Versus Uniform Grain Size Sediment Pulses In A Gravel-Bedded River, Muneer Ahammad, Jonathan A. Czuba, Allison M. Pfeiffer, Brendan P. Murphy, Patrick Belmont

Watershed Sciences Faculty Publications

Mountain rivers often receive sediment in the form of episodic, discrete pulses from a variety of natural and anthropogenic processes. Once emplaced in the river, the movement of this sediment depends on flow, grain size distribution, and channel and network geometry. Here, we simulate downstream bed elevation changes that result from discrete inputs of sediment (10,000 m³), differing in volume and grain size distribution, under medium and high flow conditions. We specifically focus on comparing bed responses between mixed and uniform grain size sediment pulses. This work builds on a Lagrangian, bed-material sediment transport model and applies it …

Growth–Defense Trade-Offs Shape Population Genetic Composition In An Iconic Forest Tree Species, Olivia L. Cope, Ken Keefover-Ring, Eric L. Kruger, Richard L. Lindroth

Aspen Bibliography

All organisms experience fundamental conflicts between divergent metabolic processes. In plants, a pivotal conflict occurs between allocation to growth, which accelerates resource acquisition, and to defense, which protects existing tissue against herbivory. Trade-offs between growth and defense traits are not universally observed, and a central prediction of plant evolutionary ecology is that context-dependence of these trade-offs contributes to the maintenance of intraspecific variation in defense [Züst and Agrawal, Annu. Rev. Plant Biol., 68, 513–534 (2017)]. This prediction has rarely been tested, however, and the evolutionary consequences of growth–defense trade-offs in different environments are poorly understood, especially in long-lived species …

Hyperspectral Imaging With Cost-Sensitive Learning For High-Throughput Screening Of Loblolly Pine (Pinus Taeda L.) Seedlings For Freeze Tolerance, Yuzhen Lu, Kitt G. Payn, Piyush Pandey, Juan J. Acosta, Austin J. Heine, Trevor D. Walker, Sierra Young

Civil and Environmental Engineering Faculty Publications

Loblolly pine (Pinus taeda L.) is a commercially important timber species planted across a wide temperature gradient in the southeastern U.S. It is critical to ensure that the planting stock is suitably adapted to the growing environment to achieve high productivity and survival. Long-term field studies, although considered the most reliable method for assessing cold hardiness of loblolly pine, are extremely resource-intensive and time-consuming. The development of a high-throughput screening tool to characterize and classify freeze tolerance among different genetic entries of seedlings will facilitate accurate deployment of highly productive and well-adapted families across the landscape. This study presents a …

Hyperspectral Imaging Combined With Machine Learning For The Detection Of Fusiform Rust Disease Incidence In Loblolly Pine Seedlings, Piyush Pandey, Kitt G. Payn, Yuzhen Lu, Austin J. Heine, Trevor D. Walker, Juan J. Acosta, Sierra N. Young

Civil and Environmental Engineering Faculty Publications

Loblolly pine is an economically important timber species in the United States, with almost 1 billion seedlings produced annually. The most significant disease affecting this species is fusiform rust, caused by Cronartium quercuum f. sp. fusiforme. Testing for disease resistance in the greenhouse involves artificial inoculation of seedlings followed by visual inspection for disease incidence. An automated, high-throughput phenotyping method could improve both the efficiency and accuracy of the disease screening process. This study investigates the use of hyperspectral imaging for the detection of diseased seedlings. A nursery trial comprising families with known in-field rust resistance data was conducted, and …

All Current Publications

Sycamore scale feeds on foliage of London planetree and California sycamore in urbanized areas throughout Utah. The insect is difficult to see with the naked eye, so we rely on the primary symptom of yellow-to-brown leaf spots. If needed, the timing of treatment is at bud break and involves oil application and/or a soil-applied systemic insecticide.

Energy Expenditure Across Immune Challenge Severities In A Lizard: Consequences For Innate Immunity, Locomotor Performance And Oxidative Status, Susannah S. French, Spencer Hudson

Browse all Datasets

Reptiles, like other vertebrates, rely on immunity to defend themselves from infection. The energetic cost of an immune response is liable to scale with infection severity, prompting constraints on other selfmaintenance traits if immune prioritization exceeds energy budget. In this study, adult male side-blotched lizards (Uta stansburiana) were injected with saline (control) or high (20 μg g−1 body mass) or low (10 μg g−1 body mass) concentrations of lipopolysaccharide (LPS) to simulate bacterial infections of discrete severities. The costs and consequences of the immune response were assessed through comparisons of change in resting metabolic rate (RMR), energy metabolites (glucose, glycerol, …

Wild Boar In Flanders, Belgium: (Dis)Agreements Between Key Stakeholders On Wild Boar Management Objectives, Actions, And Legal Provisions, Caroline Geeraerts, Anneleen Rutten, Emma Cartuyvels, Pieter Verschelde, Sander Devisscher, Francis Turkelboom, Paul Quataert, Jim Casaer

Human–Wildlife Interactions

Wild boar (Sus scrofa) reappeared in Flanders, Belgium in 2006 after more than half a century of absence. Besides being a native and highly valued game species in Europe, wild boar are also known to be responsible for car collisions, crop damage, disease transmission, and ecological damage at high densities. The management of wild boar therefore seeks to balance these positive and negative impacts. Given the highly fragmented landscape in Flanders and its multifunctional use, coexistence with wild boar is only possible through integrated management involving relevant stakeholder groups. However, to be successful, this requires that the management …
