Adapting Colorado River Basin Depletions To Available Water To Live Within Our Means, Jian Wang, David E. Rosenberg

Publications

The Colorado River’s two largest reservoirs are drawing down because releases exceed inflows and releases adapt to reservoir elevations instead of elevation and inflow triggers. To help slow reservoir drawdown and sustain target elevations, we introduced a new rule that adapted basin depletions to available water. We simulated inflow-based operations and validated existing operations in a new open-source exploratory model for the Colorado River Basin. We developed the exploratory model to more easily adapt Upper and Lower Basin depletions to available water, reduce run time, and lower costs to use compared to the proprietary RiverWare Colorado River Simulation System (CRSS) …

Texas Stakeholders’ Knowledge And Perceptions Of Chronic Wasting Disease Risks: Implications For Wildlife Agency Communications, Elena C. Rubino, Christopher Serenari

Human–Wildlife Interactions

Chronic wasting disease (CWD) is a fatal neurological disease impacting cervids. The disease can move swiftly through populations, making CWD management a priority for wildlife agencies across the United States. Stakeholder perceptions of CWD may shape behaviors that can negatively impact wildlife agencies. Thus, agencies need comprehensive assessments of stakeholder risk perceptions and enhanced understandings of how perceptions are formed to improve communications. Using a mail- and online-based questionnaire to collect data from September 2020 through January 2021, we surveyed 503 hunters throughout the state of Texas, USA, and 481 Texas landowners who owned property in CWD-affected counties to better …

Human–Carnivore Conflicts In A Recently Established Pakistani National Park, Rukhsana Khatoon, Maqsood Anwar, Charles H. Nilon, Matthew E. Gompper

Human–Wildlife Interactions

Human–carnivore conflicts (HCCs) are increasing globally. These conflicts may encompass competition for food resources, crop and livestock depredations, and attacks on humans. Concerns over conflicts may result in retaliatory killings of carnivores and negative views of wildlife or landscape conservation. Yet, despite the economic and conservation implications of HCCs, data regarding the magnitude and severity of the conflicts may be lacking because many incidents are unreported. To better inform this issue, we compared HCC data for 2016 to 2018 obtained from official records of the Punjab Wildlife and Parks Department for a newly established national park in the Punjab Region …

Landscape Characteristics Predict Locations For Potential Human–Wildlife Interactions With Timber Rattlesnakes In Minnesota, Usa, Ben M. Borash, Benjamin P. Pauli

Human–Wildlife Interactions

While management measures cannot eliminate human–wildlife conflicts, they have the potential to minimize the damage done to both parties, especially if areas where the nature of the potential interaction can be predicted before an encounter occurs. The timber rattlesnake (Crotalus horridus) represents a wildlife species associated with public misconceptions that may foster unwarranted fears and retribution. This species is native to the eastern and southern regions of the United States, including a small population remnant in the southeastern region of Minnesota. To gain a better understanding of the environmental predictors relevant to human–snake encounters in Minnesota (that require …

Stakeholder Knowledge And Perceptions Of Free-Roaming Equids And Their Management At A Western U.S. Land-Grant University, Hollee S. Wood, S. Nicole Frey, Terry A. Messmer

Human–Wildlife Interactions

The horse (Equus ferus caballus), originally native to North America, became extinct on the continent approximately 10,000 years ago. Horses that migrated from North America to Eurasia across the Bering Strait continued to evolve and were domesticated along with burros (E. asinus). Both species were then transported to the Americas where they were intentionally released or escaped into the wild, forming feral herds. The Wild Free-Roaming Horses and Burros Act of 1971 (WFRHBA) provided federal oversight and protection for feral horses and burros (hereafter, free-roaming equids) that inhabited designated areas on public lands in the western …

Feral Horses, Feral Asses, And Professional Politicians: Broodings From A Beleaguered Biologist, Vernon C. Bleich

Human–Wildlife Interactions

As a member of National Wild Horse and Burro Advisory Board, I gained insight into several aspects of feral equid management that previously had been somewhat cryptic. Foremost in my experience, though, was the dedication and professionalism of the board members with whom I served. During my tenure, the professional approach to management and the frustration faced by employees within the Horse and Burro Program became increasingly apparent. Further came the realization that the effectiveness of the board and program can be improved substantially, if (1) the board is provided the opportunity to rebut or counter incorrect or misleading information …

Impact Of Covid-19 On Aviation-Wildlife Strikes Across Europe, Isabel C. Metz, Marta Giordano, Dionysios Ntampakis, Marianna Moira, Anneke Hamann, Rosanne Blijleven, Jürgen J. Ebert, Alessandro Montemaggiori

Human–Wildlife Interactions

Collisions between aircraft and wildlife (i.e., wildlife strikes) pose a serious threat toward the safety of aircraft, its crew, and passengers. The effects of COVID-19 related travel restrictions on wildlife strikes are unknown. With this study, we aim to address this information gap by assessing the changes of wildlife hazard management performance across European airports during the lockdown period (e.g., period of reduced operations and borders closure in spring 2020). We also sought to raise awareness of the importance of wildlife strike prevention in times of reduced operations. The objective of our study was to compare wildlife strike data before …

Bat Mortality At Ontario Wind Farms Quantified And Compared Using Four Candidate Estimator Equations, Bethany G. Thurber, Catherine B. Jardine, J. Ryan Zimmerling

Human–Wildlife Interactions

Wind farm development is expanding globally. While wind energy is a low-cost option for new electricity supply, the impacts to wildlife populations, including bats (Chiroptera), are of ecological concern. To quantify these impacts, scientists have developed estimator equations to estimate bat mortality, which vary in assumptions related to correction factors. We compared the results of 4 estimators applied to post-construction monitoring data from Ontario, Canada, wind farms to evaluate the effects of field methods and correction factors on estimator consistency. To conduct our study, we obtained data from 21 wind farms between 2011 and 2017 for a total of 26 …

Design And Validation Of A Uniaxial Multi-Measurement Imager, Aaron J. Pung

Space Dynamics Laboratory Publications

A compact, uniaxial sensor is presented. The sensor system consists of a lens column, a light redistribution optic (LRO), a filter array, and an array of detectors. Built upon existing camera systems, each component within the optical system is rotationally symmetric about the optical axis. The LRO redirects light exiting the lens column towards detector arrays circumferentially located along the inside surface of a rectangular camera housing. Based on the significant increase in the number of available detectors, the uniaxial sensor is able to record multiple optically filtered images from a single viewpoint, providing a unique real-time diagnosis of the …

A Student’S Access To Practice-Linked Resources In An Elementary Unplugged-To-Plugged Computer Science Unit, Umar Shehzad, Jody Clarke-Midura, Victor R. Lee, Mimi Recker

Publications

This paper presents a case study of a student’s participation in an expansively-framed unplugged computer science (CS) instructional unit that leverages activities and materials not typically associated with CS: playing an “unplugged” tabletop board game and designing a paper prototype of a new game level. We use the practice-linked identity framework as a lens to characterize resources available in our instructional design and how they afforded or hindered the student’s participation across the instructional activities. Our findings highlight the importance of relational resources in influencing participation, both positively and negatively, and provide implications for the design of future CS learning …

Pcos: What They Should Be Telling You, Gracie Leavitt

Fall Student Research Symposium 2021

It is speculated that out of 14 million women in the United States, 70% are being affected by Polycystic Ovarian Syndrome, and yet it continues to be one of the most misdiagnosed or undiagnosed diseases. PCOS is a condition that stems from the endocrine system and is often determined by cysts in the ovaries, but studies have proven that that isn’t always the case nor the determining diagnostic criteria. Women aren’t given enough information when being diagnosed with PCOS, nor substantial treatment options. In a world with incredible medical advances and research happening continuously, PCOS seems to be lacking in …
