Climate change is rapidly driving global biodiversity declines. How wetland macroinvertebrate assemblages are responding is unclear, a concern given their vital function in these ecosystems. Using a data set from 769 minimally impacted depressional wetlands across the globe (467 temporary and 302 permanent), we evaluated how temperature and precipitation (average,...

Adam Belmonte, Temuulen T. Sankey, Joel Biedermann, John B. Bradford, Thomas Kolb
2022, Ecohydrology (15)
Prolonged drought conditions in semi-arid forests can lead to widespread vegetation stress and mortality. However, the distribution of these effects is not spatially uniform. We measured soil water potential at high spatial and temporal resolution using 112 sensors distributed across a ponderosa pine forest in northern...
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...

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....

Robert 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...

Emil 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...

Austin K. Baldwin, Steven R. Corsi, Owen M. Stefaniak, Luke C. Loken, Daniel L. Villeneuve, Gerald T. Ankley, Brett R. Blackwell, Peter L. Lenaker, Michelle A. Nott, Marc A. Mills
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...

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...
Similar environmental conditions are associated with Walleye and Yellow Perch recruitment success in Wisconsin lakes
Ethan J. Brandt, Zachary S. Feiner, Alexander W. Latzka, Daniel A. Isermann
2022, North American Journal of Fisheries Management (42) 630-641
Since the mid-2000s, recruitment of Walleye Sander vitreus in some northern Wisconsin lakes has declined, potentially because of climate-induced changes in lake environments. Yellow Perch Perca flavescens is also an ecologically and culturally important fish species in this region, but mechanisms driving Yellow Perch recruitment are unclear because of a lack of targeted sampling....

2022, Geothermal Resources Council Transactions (46) 1618-1637
Unoccupied Aerial Systems (UAS) can accommodate a variety of tools for mapping and monitoring hydrothermal systems (e.g., magnetic, gas, photogrammetry, and thermal infrared [TIR]). These platforms offer increased speed, coverage area, and uniformity compared to ground-based measurements, as well as lower flight height – and therefore higher resolution – than...

Richelle M. Allen-King, Rebecca L. Kiekhaefer, Daniel J. Goode, Paul A. Hsieh, Michelle M. Lorah, Thomas E. Imbrigiotta
2022, Groundwater Monitoring and Remediation (42) 23-34
We present a new field measurement and numerical interpretation method (combined termed ‘test’) to parameterize the diffusion of trichloroethene (TCE) and its biodegradation products (DPs) from the matrix of sedimentary rock. The method uses a dual-packer system to interrogate a low-permeability section of the rock matrix adjacent to a previously...
The impact of future climate on wetland habitat in a critical migratory waterfowl corridor of the Prairie Pothole Region
Owen P. McKenna
2022, Report
Depressional wetlands are extremely sensitive to changes in temperature and precipitation, so understanding how wetland inundation dynamics respond to changes in climate is essential for describing potential effects on wildlife breeding habitat. Millions of depressional basins make up the largest wetland complex in North America known as the Prairie Pothole...

Sarah N. Sells, Michael S. Mitchell, David Edward Ausband, Angela D. Luis, Douglas J. Emlen, Kevin M. Podruzny, Justin A. Gude
2022, Proceedings of the Royal Society B: Biological Sciences (289)
Ecologists have long sought to understand space use and mechanisms underlying patterns observed in nature. We developed an optimality landscape and mechanistic territory model to understand mechanisms driving space use and compared model predictions to empirical reality. We demonstrate our approach using grey wolves (Canis lupus). In the model, simulated...
