Have sustained acidic deposition decreases led to increased calcium availability in recovering watersheds of the Adirondack region of New York, USA?
Gregory B. Lawrence, Jason Siemion, Michael R. Antidormi, Donald B. Bonville, Michael McHale
2021, Soil Systems (5)
Soil calcium depletion has been strongly linked to acidic deposition in eastern North America and recent studies have begun to document the recovery of soils in response to large decreases in acidic deposition. However, increased calcium availability has not yet been seen in the B horizon, where calcium depletion has...

Samantha Engwell, Larry G. Mastin, Andrew C. Tupper, Jamie Kibler, Paula Acethorpe, G. Lord, R. Filgueira
2021, Bulletin of Volcanology (83)
Understanding the location, intensity, and likely duration of volcanic hazards is key to reducing risk from volcanic eruptions. Here, we use a novel near-real-time dataset comprising Volcanic Ash Advisories (VAAs) issued over 10 years to investigate global rates and durations of explosive volcanic activity. The VAAs were collected from the nine...

Rebecca Shaftel, Daniel J. Rinella, Eunbi Kwon, Stephen C. Brown, H. River Gates, Steve Kendall, David B. Lank, Joseph R. Liebezeit, David C. Payer, Jennie Rausch, Sarah T. Saalfeld, Brett K. Sandercock, Paul A. Smith, David H. Ward, Richard B. Lanctot
2021, Polar Biology (44) 237-257
Average annual temperatures in the Arctic increased by 2–3 °C during the second half of the twentieth century. Because shorebirds initiate northward migration to Arctic nesting sites based on cues at distant wintering grounds, climate-driven changes in the phenology of Arctic invertebrates may lead to a mismatch between the nutritional demands...

Aural and visual detection of greater sage-grouse leks: Implications for population trend estimates
Ian P. Riley, Courtney J. Conway, Bryan S. Stevens, Shane Roberts
2021, Journal of Wildlife Management (85) 508-519
Counts of greater sage-grouse (Centrocercus urophasianus) at leks have been used in harvest management, Endangered Species Act listing decisions, and land management policies for over half a century. Lek count sampling methods focus on counting male sage-grouse at known leks, primarily those observed visually from roads or vantage points, but...

Victoria Langenheim, Jorge A. Vazquez, Kevin M. Schmidt, Giovanni Guglielmo, Donald S. Sweetkind
2021, Geosphere (17) 455-478
In much of the western Cordillera of North America, the geologic framework of crustal structure generated in the Mesozoic leaves an imprint on later plutonic emplacement, subsequent structural setting, and present landscape morphology. The Merrimac plutons in the northern Sierra Nevada (California, USA) are a...

Nicasio Sepulveda, Melinda A. Lohmann
2021, Groundwater (59) 597-613
Treated wastewater with high levels of ammonia has been injected, since March 1983 into the deep saline units of the Lower Floridan aquifer (LFA) from a treatment plant near the east coast of Miami-Dade County in southeastern Florida. Monitoring wells in the plant recorded ammonia concentrations above ambient levels at...
Adaptive monitoring in action: Reconsidering design-based estimators reveals underestimation of whitebark pine disease prevalence in the Greater Yellowstone Ecosystem
Erin Shanahan, Wilson Wright, Kathryn Irvine
2021, Journal of Applied Ecology (58) 1079-1089
Identifying and understanding status and trends in ecological indicators motivates continual monitoring over decades. Many programs rely on probability surveys and their companion design-based estimators for status assessments (e.g. Horvitz–Thompson). Design-based estimators do not easily extend to trend estimation nor situations with observation errors. Field-based monitoring efforts inevitably have...

2021, JGR Solid Earth (126)
The Hayward fault in California's San Francisco Bay area produces large earthquakes, with the last occurring in 1868. We examine how physics‐based dynamic rupture modeling can be used to numerically simulate large earthquakes on not only the Hayward fault, but also its connected companions to the north and south, the...

M. Tim Tinker, Julie L. Yee, Kristin L. Laidre, Brian B. Hatfield, Michael D. Harris, Joseph A. Tomoleoni, Tom W. Bell, Emily Saarman, Lilian P. Carswell, A. Keith Miles
2021, Journal of Wildlife Management (85) 303-323
The recovery of large carnivore species from over‐exploitation can have socioecological effects; thus, reliable estimates of potential abundance and distribution represent a valuable tool for developing management objectives and recovery criteria. For sea otters (Enhydra lutris), as with many apex predators, equilibrium abundance is not constant across space but rather...
