Scale-dependent influence of the sagebrush community on genetic connectivity of the sagebrush obligate Gunnison sage-grouse
Shawna J Zimmerman, Cameron L. Aldridge, Mevin B. Hooten, Sara J. Oyler-McCance
2022, Molecular Ecology (31) 3267-3285
Habitat fragmentation and degradation impacts an organism's ability to navigate the landscape, ultimately resulting in decreased gene flow and increased extinction risk. Understanding how landscape composition impacts gene flow (i.e., connectivity) and interacts with scale is essential to conservation decision-making. We used a landscape genetics approach...
Development and application of Landsat-based wetland vegetation cover and unvegetated-vegetated marsh ratio (UVVR) for the conterminous United States
Neil K. Ganju, Brady Couvillion, Zafer Defne, Kate Ackerman
2022, Estuaries and Coasts (45) 1861-1878
Effective management and restoration of salt marshes and other vegetated intertidal habitats require objective and spatially integrated metrics of geomorphic status and vulnerability. The unvegetated-vegetated marsh ratio (UVVR), a recently developed metric, can be used to establish present-day vegetative cover, identify stability thresholds, and quantify vulnerability...

2022, Bioinspiration & Biomimetics (17)
Many aquatic animals swim by undulatory body movements and understanding the diversity of these movements could unlock the potential for designing better underwater robots. Here, we analyzed the steady swimming kinematics of a diverse group of fish species to investigate whether their undulatory movements can be represented using a series...

Christopher Huber, Matthew Flyr, Lucas Bair
2022, Western Economics Forum (20) 30-42
The Harney Basin is a closed river basin in southeastern Oregon. Surface water in the basin is used for a variety of social, economic, and ecological benefits. While some surface water uses compete with one another, others are complementary or jointly produce multiple beneficial outcomes. The objective of this study...
Volcanoes of the Mojave: The 2022 Desert Symposium field trip road log
David C. Buesch, David M. Miller, Bruce Bridenbecker, Mark Sweeney
2022, Conference Paper, Volcanoes in the Mojave: 2022 Desert symposium field guide and proceedings
Basalt lava fields, some decorated with scoria ‘cinder’ cones, are scattered around the Mojave Desert. Most basalt fields are short-lived, but the Cima volcanic field is unique in having eruptions that span ~7.5 m.y., including the youngest eruption in the Mojave Desert at ~12 ka. Xenolith-bearing basalts that...
Estimated daily mean streamflow in Iowa using the Flow-Duration Curve Transfer Method StreamStats application
Mackenzie K. Marti, Harper N. Wavra, Andrea Medenblik
2022, Newsletter
The U.S. Geological Survey (USGS) operates many streamgages throughout the country that provide historical and real-time daily streamflow information. Accurate estimates of daily streamflow and the percentage of time that a certain volume of streamflow occurs or is exceeded in a stream is crucial information for structure design and other...

David C. Buesch, Simon J Hook
2022, Conference Paper, Volcanoes in the Mojave: 2022 Desert symposium field guide and proceedings
The southwestern part of the Cima volcanic field in the Mojave National Monument, California, contains many of the youngest basaltic cinder cones and lava flows in the field (Wilshire and others, 2002). In 2014 the Hyperspectral Thermal Emission Spectrometer (HyTES) collected a swath of data across this area....

David C. Buesch, Janet Harvey
2022, Conference Paper, Volcanoes in the Mojave: 2022 Desert symposium field guide and proceedings
Wilderness areas in the Mojave Desert, California, are remote and rugged terrain, but they contain important geology for understanding faults of the eastern California shear zone (ECSZ), and remote sensing offers techniques that can optimize mapping. The Bristol–Granite Mountain fault zone (BGMFZ) is the easternmost fault of the ECSZ with...
Scenario Planning Around Resource Challenges (SPARC): A management-centered approach to scenario planning for climate adaptation
Alexander Bryan, Carolyn Armstrong Enquist
2022, Conference Paper, Collaboration now for the future: IV conference on the biodiversity and management of the Madrean Archipelago
Scenario planning is a strategy or framework that aids making decisions under uncertainty. Inspired by widespread use in the areas of military and business, recent work has applied the strategy to anticipate the effects of climate change on natural resource management. Most scenario planning efforts identify scenarios based on uncertain...

David C. Buesch, David M. Miller, Mark E. Stelten
2022, Conference Paper, Volcanoes in the Mojave: 2022 Desert symposium field guide and proceedings
The informally named Bicycle Lake basalt forms a volcanic field in southeastern Fort Irwin, California, disrupted by three east-striking faults and linked cross-faults of the Eastern California Shear Zone, and its distribution provides a framework for assessing volcanic field development, groundwater resources, and fault offsets. Previous geochronologic studies yielded...
On the role of climate in monthly baseflow changes across the continental United States
Jessica R. Ayers, Gabriele Villarini, Keith Schilling, Christopher Jones, Andrea E. Brookfield, Samuel Zipper, William H. Farmer
2022, Journal of Hydrologic Engineering (27)
Baseflow is the portion of streamflow that comes from groundwater and subsurface sources. Although baseflow is essential for sustaining streams during low flow and drought periods, we have little information about how and why it has changed over large regions of the continental United States. The objective...

Ryan S. Crow, Karl Karlstrom, Warren Sharp, Victor Polyak, Yemane Asmerom, Laura Crossey
2022, Conference Paper, Desert Symposium Field Guide and Proceedings
Preliminary interpretation of new and updated incision rates in western Grand Canyon shows the effects of Quaternary faulting, which dampens river incision rates in the footwalls and amplifies them in the hanging walls of normal faults. In the reach between Lava Falls and Diamond Creek in western Grand Canyon, about...
Abrupt quaternary ocean-ice events in the Arctic: Evidence from the ostracode rabilimis
Thomas M. Cronin, Laura Gemery, Baylee M. Olds Olds, Alexa Regnier, Robert Poirier, Sienna Sui
2022, Micropaleontology (68) 233-242
The Arctic Ocean has experienced orbital and millennial-scale climate oscillations over the last 500 kilo-annum (ka) involving massive changes in global sea level and components of the Arctic cryosphere, including sea-ice cover, land-based ice sheets and ice shelves. Although these climate events are only partially understood, micropaleontological studies utilizing...

Robert G. Coleman, Jared T. Gooley, Robert T. Gregorory, Stephan A. Graham
2022, American Journal of Science (322) 533-560
The New Idria serpentinite body in the Coast Ranges of California is a diapir that resulted from the interaction of the migrating Mendocino trench-ridge-transform fault triple junction, transpression, metasomatic fluids, and previously subducted oceanic crust and mantle. Northward propagation of the San Andreas fault progressively eliminated...
Depth to water and water quality in groundwater wells in the Ogallala aquifer within the North Plains Groundwater Conservation District, Texas Panhandle, 2019–20, and comparison to 2012–13 conditions
Craig A. Mobley, Patricia B. Ging
2022, Scientific Investigations Report 2022-5026
The Ogallala aquifer is the primary source of water for agricultural and municipal purposes in the Texas Panhandle. Because most of the groundwater in the Texas Panhandle is withdrawn from the Ogallala aquifer, information on the quality of groundwater in the Ogallala aquifer in this part of Texas is useful...

Aftershocks preferentially occur in previously active areas
Morgan T. Page, Nicholas van der Elst
2022, The Seismic Record (2) 100-106
The clearest statistical signal in aftershock locations is that most aftershocks occur close to their mainshocks. More precisely, aftershocks are triggered at distances following a power‐law decay in distance (Felzer and Brodsky, 2006). This distance decay kernel is used in epidemic‐type aftershock sequence (ETAS) modeling and...
