Post-breeding movement and habitat use by wood frogs along an Arctic–Subarctic ecotone
Stephanie Bishir, Blake R. Hossack, LeeAnn Fishback, J. M. Davenport
2018, Arctic, Antarctic, and Alpine Research (50)
By altering essential micro- and macrohabitat conditions for many organisms, climate change is already causing disproportionately greater impacts on Arctic and Subarctic ecosystems. Yet there is a lack of basic information about many species in northern latitudes, including amphibians. We used radio telemetry to study the post-breeding movements and habitat...

Minghua Zhang, Scott Jackson, Mark A. Robertson, Michael R. Zeiss, editor(s)
2018, Book chapter, Managing and analyzing pesticide use data for pest management, environmental monitoring, public health, and public policy. ACS Symposium Series, Vol. 1283
The U.S. Geological Survey (USGS) has been collecting data on the occurrence of pesticides in California surface and ground water since the 1970’s. The design of these studies benefited from the availability of the Pesticide Use Reporting (PUR) database of the California Department of Pesticide Regulation. Actual locations and dates...

Carving Grand Canyon’s inner gorge: A test of steady incision versus rapid knickzone migration
Ryan S. Crow, Karl E. Karlstrom, Laura J. Crossey, Victor Polyak, Yemane Asmerom, William C. McIntosh
2018, Geosphere (14) 1-17
A recent study posits that much of the 240-m-deep inner gorge of Grand Canyon was carved between 500 and 400 ka via passage of a migrating knickzone with incision rates of ~1600 m/Ma during that time period; this was based on dating of a ca. 500 ka travertine deposit perched...
Stratifying ocean sampling globally and with depth to account for environmental variability
Mark John Costello, Zeenatul Basher, Roger Sayre, Sean P. Breyer, Dawn J. Wright
2018, Scientific Reports (8) 1-9
With increasing depth, the ocean is less sampled for physical, chemical and biological variables. Using the Global Marine Environmental Datasets (GMED) and Ecological Marine Units (EMUs), we show that spatial variation in environmental variables decreases with depth. This is also the case over temporal scales because seasonal change, surface weather conditions, and biological...

Measuring and modelling the permeability of tight rocks remains a challenging task. In addition to the traditional sources of errors that affect more permeable formations (e.g. sample selection, non-representative specimens, disturbance introduced during sample acquisition and preparation), tight rocks can be particularly prone to solid–fluid interactions and thus more sensitive...

2018, Bulletin of the Seismological Society of America (108) 2478-2492
Ground‐motion prediction equations (GMPEs) are critical elements of probabilistic seismic hazard analysis (PSHA), as well as for other applications of ground motions. To isolate the path component for the purpose of building nonergodic GMPEs, we compute a regional GMPE using a large dataset of peak ground accelerations (PGAs) from small‐magnitude...

Christopher M. Hobza, Aaron R. Schepers
2018, Scientific Investigations Report 2018-5093
Streams in the Loup River Basin are sensitive to groundwater withdrawals because of the close hydrologic connection between groundwater and surface water. Groundwater discharge is the primary component of streamflow in the Loup River Basin and constitutes more than 90 percent of streamflow in the central part of the Sand...

Survival, travel time, and utilization of Yolo Bypass, California, by outmigrating acoustic-tagged late-fall Chinook salmon
Adam C. Pope, Russell W. Perry, Dalton J. Hance, Hal C. Hansel
2018, Open-File Report 2018-1118
Juvenile Chinook salmon (Oncorhynchus tshawytscha) migrating through California's Sacramento-San Joaquin River Delta toward the Pacific Ocean face numerous challenges to their survival. The Yolo Bypass is a broad floodplain of the Sacramento River that floods in about 70 percent of years in response to large, uncontrolled runoff events. As...
Refinement of a regression-based method for prediction of flow-duration curves of daily streamflow in the conterminous United States
Thomas M. Over, William H. Farmer, Amy M. Russell
