To The Moon And Mars And Back To The Archives: Working With Modern Space Collections At The University Of Arizona Libraries, Molly Stothert-Maurer, Lisa E. Duncan
To The Moon And Mars And Back To The Archives: Working With Modern Space Collections At The University Of Arizona Libraries, Molly Stothert-Maurer, Lisa E. Duncan
Journal of Western Archives
With a long history at the University of Arizona with excellence in the lunar and planetary sciences, the University of Arizona Libraries Special Collections has increased its collecting of the History of Science and Technology. These large, modern space collections pose unique challenges and require specific needs to be addressed in order for the collections to be stored, processed and made available for access. It is essential for archivists working with these collections to ask their donors the right questions and learn the limitations and restrictions that often come with acquiring modern space collections. Archives around the country have started …
Pack It Out Utah: Usu Water Quality Extension Leads Utah’S Statewide Trails And Waterways Cleanup, Lauren Houskeeper, Hope Braithwaite
Pack It Out Utah: Usu Water Quality Extension Leads Utah’S Statewide Trails And Waterways Cleanup, Lauren Houskeeper, Hope Braithwaite
Outcomes and Impact Quarterly
Utah’s public lands have experienced a surge in outdoor recreation which has led to an increase in garbage on trails, parks, neighborhoods, and eventually, in our waterways. In response, Utah State University Water Quality Extension initiated an annual statewide cleanup to raise awareness and facilitate the proper disposal of litter. During the cleanup events in 2020 and 2021, over 11,000 pounds of trash were removed from our public lands and waterways.
U.S. Public Opinion Of Reproductive Control Options For Free-Roaming Horses On Western Public Lands, S. Nicole Frey, Jeffrey L. Beck, John Derek Scasta, Loretta Singletary
U.S. Public Opinion Of Reproductive Control Options For Free-Roaming Horses On Western Public Lands, S. Nicole Frey, Jeffrey L. Beck, John Derek Scasta, Loretta Singletary
Human–Wildlife Interactions
Free-roaming horses (Equus ferus caballus; horses) inhabit public rangelands located primarily in 10 western U.S. states. Recent horse population increases are impacting rangeland ecosystems, native wildlife species and their habitats, and exacerbating conflicts with domestic livestock grazing. While contraceptives and physical sterilization are promising options to manage horse herd levels, public opinion concerning the use of fertility control is not well understood. To better inform policymakers, we completed a rigorous study of a random sample of public land stakeholders across the United States (n = 3,500) in 2020 using a Likert scale online survey to assess their …

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