Mississippian sedimentary facies patterns in east-central California and implications for development of the Permian last chance thrust
Calvin H. Stevens, Paul Stone
2022, SEPM Special Publication (113) 72-86
Mississippian sedimentary facies belts in east-central California, occurring primarily in the autochthon (lower plate) of the Last Chance Thrust, are consistently oriented in a northeast–southwest direction. The boundary of one belt is marked by the depositional limit of the Osagean to Meramecian Santa Rosa Hills Limestone; a second belt farther...

2022, Report, State of the Great Lakes 2022 Technical Report
The overall status of groundwater quality in the Great Lakes Basin is assessed as “Good” (Figure 1). For the assessed fraction of the basin (84% of the total area), the groundwater quality is “Good” in 58% of the area, “Fair” in 41% of the area, and “Poor” in 1% of...
Mapping structural control through analysis of land-surface deformation for the Rialto-Colton groundwater subbasin, San Bernardino County, California, 1992–2010
Justin T. Brandt
2022, Open-File Report 2022-1030
The locations of many faults in and near the Rialto-Colton groundwater subbasin are not precisely known because the spatial density of existing lithologic and hydrologic data used to infer the locations of faults can be sparse. The U.S. Geological Survey, in cooperation with the San Bernardino Valley Municipal Water District,...
Volcanic electrification: Recent advances and future perspectives
Corrado Cimarelli, Sonja A Behnke, Kimberly Genareau, Joshua Méndez Harper, Alexa R. Van Eaton
2022, Bulletin of Volcanology (84)
The electrification of volcanic plumes has been described intermittently since at least the time of Pliny the Younger and the 79 AD eruption of Vesuvius. Although sometimes disregarded in the past as secondary effects, recent work suggests that the electrical properties of volcanic plumes reveal intrinsic and otherwise inaccessible parameters...

Key observations of flexed-leg urination in the free-ranging Gray Wolf (Canis lupus)
L. David Mech, Rick McIntyre
2022, Canadian Field Naturalist (136) 10-12
Flexed-leg urination (FLU) in female Gray Wolves (Canis lupus) has been little studied in the wild. Captive females in packs do not exhibit FLU unless they are both mature and dominant to an associate female, but these characteristics have not been confirmed in free-ranging wolves. We present observations of...

Avian influenza viruses can pose serious risks to agricultural production, human health, and wildlife. An understanding of viruses in wild reservoir species across time and space is important to informing surveillance programs, risk models, and potential population impacts for vulnerable species. Although it is recognized that...

Keenan Yakola, Adrian Jordaan, Stephen Kress, Paula Shannon, Michelle Staudinger
2022, Waterbirds (44) 397-414
The Gulf of Maine, USA is home to four colonial co-nesting tern species: Least Tern (Sternula antillarum), Common Tern (Sterna hirundo), Arctic Tern (Sterna paradisaea), and the federally endangered Roseate Tern (Sterna dougallii). Over three decades of visual observations of chick provisioning were compiled for...
Nutrient restoration of a large, impounded, ultra-oligotrophic western river to recover declining native fishes
Ryan S. Hardy, Tyler J. Ross, Kevin McDonnell, Michael Quist, Charlie Holderman, Bryan S. Stevens
2022, North American Journal of Fisheries Management (42) 977-993
Declines in many fish populations in large, western rivers have been primarily attributed to the anthropogenic reduction of nutrient inputs and subsequent impacts to the food web. The largest known river fertilization program was implemented starting in 2005 on the Kootenai River in northern Idaho...

Raposa, Jason A. Garwood, Nicole Kahn
2022, Science (377) 523-527
Much uncertainty exists about the vulnerability of valuable tidal marsh ecosystems to relative sea level rise. Previous assessments of resilience to sea level rise, to which marshes can adjust by sediment accretion and elevation gain, revealed contrasting results, depending on contemporary or Holocene geological data. By analyzing globally distributed contemporary...

Jessie Kate Saunders, Sarah E. Minson, Annemarie S. Baltay Sundstrom, Julian J Bunn, Elizabeth S. Cochran, Deborah L. Kilb, Colin T O’Rourke, Mitsuyuki Hoshiba, Yuki Kodera
2022, Bulletin of the Seismological Society of America (112) 2668-2688
We examine the real‐time earthquake detection and alerting behavior of the Propagation of Local Undamped Motion (PLUM) earthquake early warning (EEW) algorithm and compare PLUM’s performance with the real‐time performance of the current source‐characterization‐based ShakeAlert System. In the United States (U.S.), PLUM uses a two‐station approach to detect earthquakes. Once...

Since 1972, the Landsat program has been continually monitoring the Earth, to now provide 50 years of digital, multispectral, medium spatial resolution observations. Over this time, Landsat data were crucial for many scientific and technical advances. Prior to the Landsat program, detailed, synoptic depictions of the Earth's surface were rare, and the ability to acquire...

Island of misfit tortoises: Waif gopher tortoise health assessment following translocation
Rebecca K. McKee, Kurt. A. Buhlmann, Clinton T. Moore, Matthew C. Allender, Nicole I. Stacy, Tracey D. Tuberville
2022, Conservation Physiology (10)
Translocation, the intentional movement of animals from one location to another, is a common management practice for the gopher tortoise (Gopherus polyphemus). Although the inadvertent spread of pathogens is a concern with any translocation effort, waif tortoises—individuals that have been collected illegally, injured and rehabilitated or have unknown origins—are...
Field-trip guide to continental arc to rift volcanism of the southern Rocky Mountains—Southern Rocky Mountain, Taos Plateau, and Jemez Mountains volcanic fields of southern Colorado and northern New Mexico

2022, Scientific Investigations Report 2017-5022-R
The southern Rocky Mountains of northern New Mexico and southern Colorado preserve the Oligocene to Pleistocene record of North American continental arc to rift volcanism. The 35–23 million year old (Ma) southern Rocky Mountain volcanic field (SRMVF), spectacularly preserved in the San Juan Mountains of southern Colorado, records the evolution...

Rylen K. Nakama, Jackson N. Mitchell, Delwyn S. Oki
2022, Open-File Report 2022-1069
A reported fuel release in November 2021 at the Red Hill Bulk Fuel Storage Facility within the naval reservation at Red Hill led to the shutdown of several production wells in the Hālawa area, O‘ahu, Hawai‘i. Red Hill Shaft—one of the high-capacity production wells that shut down—was reactivated on January...
Effects of warming winter embryo incubation temperatures on larval cisco (Coregonus artedi) survival, growth, and critical thermal maximum
Taylor R. Stewart, Mark Vinson, Jason D. Stockwell
2022, Journal of Great Lakes Research (48) 1042-1049
Freshwater whitefishes, Salmonidae Coregoninae, are cold stenothermic fishes of ecological and socio-economic importance in northern hemisphere lakes that are warming in response to climate change. To address the effect of warming waters on coregonine reproduction we experimentally evaluated different embryo incubation temperatures on post-hatching survival, growth, and critical thermal maximum...

Milton Ordonez, Carlos La Verde, Maurizio Battaglia
2022, Journal of Vulcanological and Geothermal Research (430)
The morphology of the summit of Nevado del Ruiz volcano (Colombia) and its active Arenas crater is the product of complex interactions between effusive and explosive eruptions, and the dynamics of the summit glacier. Here, we document the morphologic evolution of the summit of...
Implications of habitat-driven survival and dispersal on recruitment in a spatially structured piping plover population
Rose J. Swift, Michael J. Anteau, Kristen S. Ellis, Megan M. Ring, Mark H. Sherfy, Dustin L. Toy, David N. Koons
2022, Ecosphere (13)
Natal survival and dispersal have important consequences for populations through the movement of genes and individuals. Metapopulation theory predicts either balanced natal dispersal among regions or source–sink dynamics, which can dramatically change population structure. For species reliant on dynamic, early-successional habitats, availability and location of habitat...
