Long-term research on large ungulate populations typically conjures perceptions of extensive (and expensive) animal capture and telemetry work, and subsequent advanced modeling of resource selection and population dynamics that inform management decisions. In contrast, studies lacking a telemetry component are often limited to animal behavior or natural history. Although compelling...

Sarah Ellen Johnston, Matthew J. Bogard, Jennifer A. Rogers, David Butman, Robert G. Striegl, Mark M. Dornblaser, Robert G. M. Spencer
2019, Biogeochemistry (146) 271-292
Circumpolar lakes comprise ~ 1.4 million km2 of arctic and subarctic landscapes and are vulnerable to change in vegetation, permafrost distribution, and hydrological conditions in response to climate warming. However, the composition and cycling of dissolved organic matter (DOM) is poorly understood for these lakes because most are remote...
Historical range and variation (HRV)
Robert Keane, Rachel A. Loehman
2019, Book chapter, Encyclopedia of Wildfires and Wildland-Urban Interface (WUI) Fires
Fire-prone landscapes are experiencing rapid and potentially persistent changes as the result of complex and potentially novel interactions of anthropogenic climate changes, shifting fire regimes, exotic plant, insect, and pathogen invasions, and industrial, agricultural, and urban development. Are these landscapes fully departed from historical conditions? Should they be managed...

2019, Science of the Total Environment (700)
Trace organic compounds in deep ice cores supply important paleoclimatic information. Untargeted analyses of dissolved organic matter provide an overview of molecular species in ice samples however, sample volumes usually required for these analyses are generally not available from deep ice cores. Here, we developed an analytical method using a...

Kevin M. Bakker, Tonie E. Rocke, Jorge E. Osorio, Rachel C. Abbott, Carlos Tello, Jorge Carerra, William Valderrama, Carlos Shiva, Nestor Falcon, Daniel G. Streicker
2019, Nature Ecology and Evotution (3) 1697-1704
Vaccines that autonomously transfer among individuals have been proposed as a strategy to control infectious diseases within inaccessible wildlife populations. However, rates of vaccine spread and epidemiological efficacy in real-world systems remain elusive. Here, we investigate whether topical vaccines that transfer among individuals through social contacts can control vampire bat...
Behavioural plasticity modulates temperature-related constraints on foraging time for a montane mammal
L. Embere Hall, Anna D. Chalfoun
2019, Journal of Animal Ecology (88) 363-375
Contemporary climate change is altering temperature profiles across the globe. Increasing temperatures can reduce the amount of time during which conditions are suitable for animals to engage in essential activities, such as securing food. Behavioural plasticity, the ability to alter behaviour in response to the environment, may provide animals...

Lauren M. Zinsser
2019, Scientific Investigations Report 2019-5113
The Coeur d’Alene mining district in northern Idaho historically was a globally important source of lead, zinc, and silver, but over 100 years of mining has left a legacy of metals contamination in the Coeur d’Alene River valley. Previous studies by the U.S. Geological Survey (USGS) and others have indicated...

Simultaneous autoregressive (SAR) model
Mevin Hooten, Jay M. Ver Hoef, Ephraim M. Hanks
2019, Book chapter, Wiley StatsRef: Statistics reference online
Simultaneous autoregressive (SAR) models are useful for accommodating various forms of dependence among data that have discrete support in a space of interest. These models are often specified hierarchically as mixed-effects regression models with first-moment structure controlled by a conventional linear regression term and second-moment structure induced by correlated random...

Floodplain inundation spectrum across the United States
Durelle T. Scott, Jesus D. Gomez-Velez, C. Nathan Jones, Judson Harvey
2019, Nature Communications (10)
Floodplain inundation poses both risks and benefits to society. In this study, we characterize floodplain inundation across the United States using 5800 stream gages. We find that between 4% and 12.6% of a river’s annual flow moves through its floodplains. Flood duration and magnitude is greater in...

Instructions for running the analytical code PAT (Purge Analyzer Tool) for computation of in-well time of travel of groundwater under pumping conditions
P.T. Harte, B. J. Huffman, Tomas Perina, Herb Levine, Daewon Rojas-Mickelson
2019, Open-File Report 2019-1104
IntroductionUnderstanding the optimal time needed to purge a well while pumping to collect a representative groundwater sample requires an understanding of groundwater flow in wells (in-well flow). Parameters that affect in-well flow include the hydraulic properties of the aquifer, well construction, drawdown from pumping, and pump rate. The time of...
Using stream-side groundwater discharge for geochemical exploration in mountainous terrain
Andrew H. Manning, Jean M. Morrison, Richard Wanty, Christopher T. Mills
2019, Journal of Geochemical Exploration (209)
Groundwater chemistry has been predominantly used in geochemical exploration studies to identify mineralized targets concealed under transported cover in areas with gentle topography. Another potentially valuable ap-plication that has received little attention is using groundwater chemistry to identify deposits concealed within mountain ridges. A number of geochemical exploration studies have...
Adult monarch (Danaus plexippus) abundance is higher in burned sites than in grazed sites
Julia B. Leone, Diane L. Larson, Jennifer L. Larson, Patrick Pennarola, Karen Oberhauser
2019, Frontiers in Ecology and Evolution (7)
Much of the remaining suitable habitat for monarchs (Danaus plexippus) in Minnesota is found in tallgrass prairies. We studied the association of adult monarch abundance with use of fire or grazing to manage prairies. Sites (n=20) ranged in size from 1 to 145 hectares and included land owned and managed...
The power, potential, and pitfalls of open access biodiversity data in range size assessments: Lessons from the fishes
Abigail Benson
2019, Ecological Indicators (110)
Geographic rarity is a driver of a species’ intrinsic risk of extinction. It encompasses multiple key components including range size, which is one of the most commonly measured estimates of geographic rarity. Range size estimates are often used to prioritize conservation efforts when there are multiple candidate species, because data...
