Defining the Hoek-Brown constant mi for volcanic lithologies
Marlène C. Villeneuve, Michael J. Heap, Lauren N. Schaefer
2022, Conference Paper, Rock mechanics and engineering geology in volcanic fields
The empirical Hoek-Brown failure criterion is a well-known and commonly used failure criterion for both intact rocks and rock masses, especially in geological engineering. The intact criterion is calculated using experimental triaxial compression test results on intact samples while the rock mass criterion modifies the intact strength using quantified measures...
Nonlethal tools to identify mass ovarian follicular atresia in Burbot
Lauren M. McGarvey, Jason E. Ilgen, Christopher S. Guy, Jason G. McLellan, Molly A. H. Webb
2022, Journal of Fish and Wildlife Management (13) 552-561
Skipped spawning, or variation in spawning periodicity, occurs in many annual spawning fish species and is an important consideration for population management. We assessed plasma sex steroid concentrations and measured gonad size and ovarian follicle diameter as metrics to nonlethally identify mass ovarian...
Maladaptive nest-site selection and reduced nest survival in female sage-grouse following wildfire
Ian F. Dudley, Peter S. Coates, Brian G. Prochazka, Dawn M. Davis, Scott C. Gardner, David J. Delehanty
2022, Ecosphere (13)
Increased wildfire frequency and associated replacement of sagebrush (Artemisia spp.) with invasive annual grasses contribute to declines of greater sage-grouse (Centrocercus urophasianus; hereafter, sage-grouse) populations across the Great Basin. However, little is known about wildfire effects on sage-grouse nest-site selection and nest survival, which can influence population persistence. The primary objective...

Robert E. Wilson, Sarah A. Sonsthagen, Jeffrey M. DaCost, Michael D. Sorenson, Anthony D. Fox, Melanie Weaver, Dan Skalos, Alexander V. Kondratyev, Kim T. Scribner, Alyn Walsh, Craig R. Ely, Sandra L. Talbot
2022, Diversity (14)
Migration schedules and the timing of other annual events (e.g., pair formation and molt) can affect the distribution of genetic diversity as much as where these events occur. The greater white-fronted goose (Anser albifrons) is a circumpolar goose species, exhibiting temporal and spatial variation of events among populations during...

2022, Scientific Data (9)
The Chesapeake Bay is a region along the eastern coast of the United States where sea-level rise is confounded with poorly resolved rates of land subsidence, thus new constraints on vertical land motions (VLM) in the region are warranted. In this paper, we provide a description of two campaign-style Global...
Analog field-scale acoustic study of volcanic eruption directivity using a tiltable liquid nitrogen-charged water cannon
A.D. Jolly, Benjamin Kennedy, Robin S. Matoza, Alexandra M. Iezzi, Bruce W. Christensen, Richard Johnson, Amilea Sork, David Fee
2022, Earth, Planets and Space (74)
Laterally directed explosive eruptions are responsible for multiple fatalities over the past decade and are an increasingly important volcanology problem. To understand the energy dynamics for these events, we collected field-scale explosion data from nine acoustic sensors surrounding a tiltable cannon as part of an exploratory experimental design. For each...
Wetland ecosystem health and biodiversity

2022, Report, Third Triennial Report to Congress on Biofuels
• Cropland expansion from 2008 to 2016 was mostly from losses of grassland (88%), with 3% losses from wetlands (a total of nearly 275,000 acres of wetlands, concentrated in the Prairie Pothole Region). Given the lack of national or regional datasets to track changes in RFS acreage, the extent of...
Appendix 7: Application of joint dynamic species distribution models to at-sea survey data for seabirds in the Bering Strait and Chukchi Sea
Mayumi L. Arimitsu, Kathy Kuletz
2022, Report, Marine bird distribution and abundance in offshore waters
Mitigating risk to migratory birds from energy development requires information on the distribution and abundance of seabirds in offshore waters. Seabirds are highly mobile, with species-specific seasonal migrations that result in variable patterns of distribution in space and time. In remote offshore marine areas, obtaining useful and current information on...

Effects of release techniques on parent-reared whooping cranes in the eastern migratory population
Hillary L. Thompson, M. Susanna Mann, Marianne Wellington, Kim H. Boardman, Glenn H. Olsen
2022, Proceedings of the North American Crane Workshop (15) 53-71
Reintroduction of an Eastern Migratory Population (EMP) of whooping cranes (Grus americana) in the United States by release of captive-reared individuals began in 2001. As of 2020, the EMP has approximately 21 breeding pairs and has had limited recruitment of wild-hatched individuals, thus captive-reared juveniles continue...

The lack of consistent, accurate information on evapotranspiration (ET) and consumptive use of water by irrigated agriculture is one of the most important data gaps for water managers in the western United States (U.S.) and other arid agricultural regions globally. The ability to easily access information...
Density-dependent and environmental influences on juvenile walleye Sander vitreus (Mitchill) survivorship in northern Wisconsin lakes
Logan R. Zebro, Joseph T. Mrnak, Stephanie L. Shaw, Steven R. Chipps, Greg G. Sass
2022, Fisheries Management and Ecology (29) 897-910
Walleye, Sander vitreus (Mitchill), natural recruitment has declined in northern Wisconsin lakes over time. Age-0 and age-1 walleye relative abundance (catch per unit effort; CPE) data from northern Wisconsin (1986–2019) were used to test for abiotic (i.e. lake characteristics and temperature variables) and biotic (age-0 and age-1 CPE) factors influencing age-0 to...
