Integrating distance sampling survey data with population indices to separate trends in abundance and temporary immigration
Joshua H. Schmidt, Tammy L. Wilson, William L. Thompson, Buck A. Mangipane
2022, Journal of Wildlife Management (86)
Managers rely on accurate estimators of wildlife abundance and trends for management decisions. Despite the focus of contemporary wildlife science on developing methods to improve inference from wildlife surveys, legacy datasets often rely on index counts that lack information about the detection process. Data integration can be a useful tool...

Alexa R. Van Eaton, Cassandra M Smith, Michael J. Pavolonis, Ryan Said
2022, Geology (50) 491-495
Advances in global lightning detection have provided novel ways to characterize explosive volcanism. However, researchers are still at the early stages of understanding how volcanic plumes become electrified on different spatial and temporal scales. We deconstructed the phreatomagmatic eruption of Taal volcano (Philippines) on 12 January 2020 to investigate the...
No evidence for tephra in Greenland from the historic eruption of Vesuvius in 79 CE: Implications for geochronology and paleoclimatology
Gill Plunkett, Michael Sigl, Hans Schwaiger, Emma Tomlinson, Matt Toohey, Joseph R. McConnell, Jonathan R. Pilcher, Takeshi Hasegawa, Claus Siebe
2022, Climate of the Past (18) 45-65
Volcanic fallout in polar ice sheets provides important opportunities to date and correlate ice-core records as well as to investigate the environmental impacts of eruptions. Only the geochemical characterization of volcanic ash (tephra) embedded in the ice strata can confirm the source of the eruption, however, and is a requisite...
Characterization of ambient groundwater quality within a statewide, fixed-station monitoring network in Pennsylvania, 2015–19
Matthew D. Conlon, Joseph W. Duris
2022, Scientific Investigations Report 2021-5119
Pennsylvania leads the Nation in the number of individuals that use groundwater for private domestic water supply; more than 3 million rural and suburban Pennsylvania residents rely on private domestic supplies for drinking water. These supplies are not regulated nor routinely monitored; thus relevant groundwater-quality information is not widely available....
A pilot study to assess the influence of infiltrated stormwater on groundwater: Hydrology and trace organic contaminants
Sarah M. Elliott, Richard L. Kiesling, Andrew M. Berg, Heiko L. Schoenfuss
2022, Water Environment Research (94)
Underground infiltration basins (UIBs) mimic the natural hydrologic cycle by allowing stormwater to recharge local groundwater aquifers. However, little is known about the potential transport of organic contaminants to receiving groundwater. We conducted a pilot study in which we collected paired grab samples of stormwater runoff flowing into two UIBs...

Robert E. Anthony, Adam T. Ringler, David C. Wilson
2022, Bulletin of the Seismological Society of America (112) 646-668
Since 2004, the most complete estimate of background noise levels across the continental U.S. was attained using 61 broadband seismic stations to calculate power spectral density (PSD) probability density functions. To improve seismic noise estimates across the U.S., we examine vertical component seismic data from the EarthScope USArray Transportable Array...

E. D. Attanasi, Philip A. Freeman
2022, Natural Resources Research (31) 735-749
This paper analyzes the relationship between actual reservoir conditions and predicted measures of performance of carbon dioxide enhanced oil recovery (CO2–EOR) programs. It then shows how CO2–EOR operators might maximize the value of their projects by approaching implementation using a “flexible selective” pattern development strategy, where...

Guthrie S. Zimmerman, Brian Millsap, Fitsum Abadi, Jay V. Gedir, William L. Kendall, John R. Sauer
2022, Journal of Wildlife Management (86)
Effectively managing take of wildlife resulting from human activities poses a major challenge for applied conservation. Demographic data essential to decisions regarding take are often expensive to collect and are either not available or based on limited studies for many species. Therefore, modeling approaches...

Of all terrestrial biomes, grasslands are losing the most biodiversity the most rapidly, so there is a critical need to document and learn from large-scale restoration successes.In the Loess Canyons ecoregion of the Great Plains, USA, an association of private ranchers and natural resource agencies has led a multi-decadal,...
BIOTAS: BIOTelemetry Analysis Software, for the semi-automated removal of false positives from radio telemetry data
Kevin Nebiolo, Theodore R. Castro-Santos
2022, Animal Biotelemetry (10) 1-16
IntroductionRadio telemetry, one of the most widely used techniques for tracking wildlife and fisheries populations, has a false-positive problem. Bias from false-positive detections can affect many important derived metrics, such as home range estimation, site occupation, survival, and migration timing. False-positive removal processes have relied upon simple filters...

2022, Environmental Toxicology and Chemistry (41) 1016-1041
With improved analytical techniques, environmental monitoring studies are increasingly able to report the occurrence of tens or hundreds of chemicals per site, making it difficult to identify the most relevant chemicals from a biological standpoint. For this study, organic chemical occurrence was examined, individually and as mixtures, in the context...
Individual heterogeneity influences the effects of translocation on urban dispersal of an invasive reptile
Abigail B. Fueka, Melia G. Nafus, Amy A. Yackel Adams, Larissa L. Bailey, Mevin B. Hooten
2022, Movement Ecology (10)
BackgroundInvasive reptiles pose a serious threat to global biodiversity, but early detection of individuals in an incipient population is often hindered by their cryptic nature, sporadic movements, and variation among individuals. Little is known about the mechanisms that affect the movement of these species, which limits our understanding of their...
Seed germination responses to salinity for three rare wetland plants of spring-fed arid systems
Antonio Cantu de Leija, Sammy L. King, Tracy S. Hawkins
2022, Journal of Arid Environments (199)
Spring-fed wetlands within arid systems host unique species of plants, many of which are threatened due to the vulnerability of these ecosystems. Increased salinity and drier hydrologic regimes due to anthropogenic activities threaten these systems. Furthermore, limited knowledge regarding key life history traits of species jeopardize the restoration and management...
Geographic variation and thermal plasticity shape salamander metabolic rates under current and future climates
D. J. Munoz, D. A. W. Miller, R. Schilder, Evan H. Campbell Grant
2022, Ecology and Evolution (12)
Predicted changes in global temperature are expected to increase extinction risk for ectotherms, primarily through increased metabolic rates. Higher metabolic rates generate increased maintenance energy costs which are a major component of energy budgets. Organisms often employ plastic or evolutionary (e.g., local adaptation) mechanisms to optimize metabolic rate with respect...

Brian Buchanan, Suresh Sethi, Scott Cuppett, Megan Lung, George Jackman, Liam Zarri, Ethan Duvall, Jeremy Dietrich, Patrick Sullivan, Alon Dominitz, Josephine Archibald, Alexander Flecker, Brian Rahm
2022, Journal of Environmental Management (302)
Restoring stream ecosystem integrity by removing unused or derelict dams has become a priority for watershed conservation globally. However, efforts to restore connectivity are constrained by the availability of accurate dam inventories which often overlook smaller unmapped riverine dams. Here we develop and test a machine learning approach to identify...
A comparison of orbital-resolution, Late Pleistocene Alkenone and foraminiferal assemblage-based sea surface temperature reconstructions from the Southwest Pacific
Emilie A. Henry, Kira T. Lawrence, Laura C. Peterson, Marci M. Robinson
2022, Quaternary Science Reviews (277)
Global and regional reconstructions of past climate conditions often incorporate sea surface temperature (SST) estimates from multiple proxies because not every paleotemperature proxy is applicable in all geographic locations. This practice of assimilating estimates from different proxies in global or regional temperature syntheses makes...
