Supplemental material for Cotterill et al. 2020: Parsing the effects of demography, climate, and management on recurrent brucellosis outbreaks in elk. Journal of Applied Ecology.

Gavin Cotterill, Johan T du Toit & Paul Cross
Zoonotic pathogens can harm human health and wellbeing directly or by impacting livestock. Pathogens that spillover from wildlife can also impair conservation efforts if humans perceive wildlife as pests. Brucellosis, caused by the bacterium Brucella abortus, circulates in elk and bison herds of the Greater Yellowstone Ecosystem and poses a risk to cattle and humans. Our goal was to understand the relative effects of climatic drivers, host demography, and management control programs on disease dynamics....

Data from: Density-dependent space use affects interpretation of camera trap detection rates

Kate Broadley, Cole Burton, Stan Boutin & Tal Avgar
Camera-traps (CTs) are an increasingly popular tool for wildlife survey and monitoring. Estimating relative abundance in unmarked species is often done using detection rate as an index of relative abundance, which assumes a positive linear relationship with true abundance. This assumption may be violated if movement behavior varies with density, but the degree to which movement is density-dependent across taxa is unclear. The potential confounding of population-level relative abundance indices by movement depends on how...

Data from: Increased soil temperature and decreased precipitation during early life stages constrain grass seedling recruitment in cold desert restoration

Jeremy J. James, Roger Sheley, Elizabeth Leger, Peter B. Adler, Stuart Hardegree, Elise Gornish & Matt Rinella
1. Seed-based restoration is one of the most difficult challenges for dryland restoration. Identifying environmental conditions that drive variation in seed and seedling mortality across similar restoration efforts could increase understanding of when and where restoration outcomes are likely to be favorable and identify new tools and strategies to improve outcomes. 2. We asked how variation in a suite of environmental predictors influenced germination, emergence, seedling establishment, and juvenile survival of four commonly sown perennial...

The data are described thoroughly in a peer-reviewed paper: Lyman S., Tran, T., Mansfield, M. Ravikumar, A., 2019. Aerial and Ground-Based Optical Gas Imaging Survey of Uinta Basin Oil and Gas Wells. These are example videos collected during a hydrocarbon emissions survey of oil and gas...

Data from: Ultra-Conserved Element phylogenomics of new world Ponera (Hymenoptera: Formicidae) illuminates the origin and phylogeographic history of the endemic exotic ant Ponera exotica

Michael G. Branstetter & John T. Longino
The genus Ponera is a lineage of leaf litter ants, with a center of diversity in the Indo-Australian region. Two species occur in the New World; however, uncertainty exists with regard to their biogeographic origins and species limits, especially for isolated cloud forest populations in Middle America. We investigate the geographic distribution, phylogeny, and phylogeography of these two species to better characterize the American ant fauna and to gain insight into the biogeography of taxa...

Data from: Weak spatiotemporal response of prey to predation risk in a freely interacting system

Jeremy J. Cusack, Michel T. Kohl, Matthew C. Metz, Tim Coulson, Daniel R. Stahler, Douglas W. Smith & Daniel R. MacNulty
1.The extent to which prey space use actively minimises predation risk continues to ignite controversy. Methodological reasons that have hindered consensus include inconsistent measurements of predation risk, biased spatiotemporal scales at which responses are measured, and lack of robust null expectations. 2.We addressed all three challenges in a comprehensive analysis of the spatiotemporal responses of adult female elk (Cervus elaphus) to the risk of predation by grey wolves (Canis lupus) during winter in northern Yellowstone,...

Data from: Patterns of nitrogen-fixing tree abundance in forests across Asia and America

Duncan N. L. Menge, Ryan A. Chisholm, Stuart J. Davies, Kamariah Abu Salim, David Allen, Mauricio Alvarez, Norm Bourg, Warren Y. Brockelman, Sarayudh Bunyavejchewin, Nathalie Butt, Min Cao, Wirong Chanthorn, Wei-Chun Chao, Keith Clay, Richard Condit, Susan Cordell, João Batista Da Silva, H. S. Dattaraja, Ana Cristina Segalin De Andrade, Alexandre A. Oliveira, Jan Den Ouden, Michael Drescher, Christine Fletcher, Christian P. Giardina, C. V. Savitri Gunatilleke … & Tak Fung
Symbiotic nitrogen (N)‐fixing trees can provide large quantities of new N to ecosystems, but only if they are sufficiently abundant. The overall abundance and latitudinal abundance distributions of N‐fixing trees are well characterised in the Americas, but less well outside the Americas. Here, we characterised the abundance of N‐fixing trees in a network of forest plots spanning five continents, ~5,000 tree species and ~4 million trees. The majority of the plots (86%) were in America...

Data from: The role of structural genomic variants in population differentiation and ecotype formation in Timema cristinae walking sticks

Kay Lucek, Zach Gompert & Patrik Nosil
Theory predicts that structural genomic variants such as inversions can promote adaptive diversification and speciation. Despite increasing empirical evidence that adaptive divergence can be triggered by one or a few large inversions, the degree to which widespread genomic regions under divergent selection are associated with structural variants remains unclear. Here we test for an association between structural variants and genomic regions that underlie parallel host-plant associated ecotype formation in Timema cristinae stick insects. Using mate-pair...

Crustal Density Variation of the Eastern U.S.

Henglei Zhang, Dhananjay Ravat & Anthony R. Lowry
EarthScope’s USArray Transportable Array (TA) has shortcomings for the purpose of interpreting geologic features of wavelengths less than the 70 km TA station spacing, but these can be overcome by using higher spatial resolution gravity data. In this study, we exploit USArray receiver functions to reduce non-uniqueness in the interpretation of gravity anomalies. We model gravity anomalies from previously-derived density variations of sedimentary basins, crustal Vp/Vs variation, Moho variation, and upper mantle density variation derived...

Data from: Wildfire, National Park Visitation, and Changes in Regional Economic Activity

Man-Keun Kim & Paul M. Jakus
The visibility, safety, and health effects of seasonal wildfires may affect recreational visits to national parks (NPs), even if fires occur outside of park boundaries. This study statistically quantifies the effect of nearby wildfire on tourist flows to each of Utah's five NPs (Arches, Bryce Canyon, Canyonlands, Capitol Reef, and Zion). Using monthly data from May 1993 to December 2015, we empirically link wildfire activities (measured as monthly area burned within 80 km, 160 km, and 320 km...

Aluminum Secondary Electron Yield

JR Dennison & Phil Lundgreen
Accurate modeling of spacecraft charging is essential to mitigate well-known and all-too-common deleterious and costly effects on spacecraft resulting from charging induced by interactions with the space plasma environment. This paper addresses how limited availability of electron emission and transport properties of spacecraft materials—in particular secondary electron yields—and the wide range measured for such properties pose a critical issue for modeling spacecraft charging. It describes a materials charging database being developed, which when used in...

Wasatch Front Preventative Capital Study

Arthur Caplan & Ramjee Acharya
We address the issue of optimal investment in “preventative capital” to mitigate episodic, mobile-source air pollution events in Utah’s Wasatch Front region. We calibrate Berry et al.'s (2015) endogenous-risk model using a unique dataset related to the region’s "red air day" episodes occurring over the past decade. Our analysis demonstrates that, under a wide range of circumstances, the optimal steady-state level of preventative capital stock – raised through the issuance of a municipal “clean air...

Data from: Life-history differences across latitude in common side blotched lizards (Uta stansburiana)

Geoffrey D. Smith, Peter A. Zani & Susannah S. French
Life‐history strategies are known to shift with latitude in many species. While life‐history variation related to body size, reproductive investment, and behavior has been studied for years, another crucial life‐history component is the immune system, which can influence an animal's survival. We measured selected life‐history traits in side‐blotched lizards in southern Utah and Oregon in the field for two consecutive years and conducted a common‐garden experiment in the laboratory to determine how organisms from different...

Peloton tracking and analysis from the 2016 Tour de France

Tadd Truscott & Jesse Belden
The work associated with this project is described in a manuscript entitled "How vision governs the collective behavior of cycling pelotons" by Belden et al., along with an electronic supplementary material document. We investigate properties of densely packed groups of bicycle racers, which are known as cycling pelotons. These pelotons exhibit features of collective animal behavior, including emergent behavior from inter-individual interactions. In this data set, we classify global shapes of the peloton, and identify...

Data from: A split sex ratio in solitary and social nests of a facultatively social bee

Adam R. Smith, Karen M. Kapheim, Callum J. Kingwell & William T. Wcislo
A classic prediction of kin selection theory is that a mixed population of social and solitary nests of haplodiploid insects should exhibit a split sex ratio among offspring: female biased in social nests, male biased in solitary nests. Here we provide the first evidence of a solitary-social split sex ratio, using the sweat bee Megalopta genalis (Halictidae). Data from 2502 offspring collected from naturally occurring nests across six years spanning the range of the M....
