Deep Learning as a tool to forecast hydrologic response for landslide-prone hillslopes
Elijah Orland, Joshua J. Roering, Matthew A. Thomas, Benjamin B. Mirus
2020, Geophysical Research Letters (47)
Empirical thresholds for landslide warning systems have benefitted from the incorporation of soil‐hydrologic monitoring data, but the mechanistic basis for their predictive capabilities is limited. Although physically based hydrologic models can accurately simulate changes in soil moisture and pore pressure that promote landslides, their utility is restricted...
Modeling the surface water and groundwater budgets of the US using MODFLOW-OWHM
Mustafa H Alattar, Tara J Troy, Tess A Russo, Scott E. Boyce
2020, Advances in Water Resources (143)
Assessments of groundwater and surface water budgets at a large scale, such as the contiguous United States, often separately analyze the complex dynamics linking the surface and subsurface categories of water resources. These dynamics include recharge and groundwater contributions to streamflow. The...
Height-related changes in forest composition, not tree vulnerability, explain increasing mortality with height during an extreme drought
Nathan L. Stephenson, Adrian Das
2020, Nature Communications (11)
Recently, Stovall et al.1 (hereafter SSY) showed that during an extreme drought, remotely sensed mortality of tall trees was more than double that of short trees. They interpreted this to be a consequence of inherently greater hydraulic vulnerability of tall trees, and suggested that tall-tree vulnerability should thus generalize...

2020, Open-File Report 2020-1061
The U.S. Army Corps of Engineers, Jacksonville District, plans to deepen the St. Johns River channel in Jacksonville, Florida, from 40 to 47 feet along 13 miles of the river channel, beginning at the mouth of the river at the Atlantic Ocean, in order to accommodate larger, fully loaded cargo...
Dietary versus nondietary fatty acid profiles of lake trout ecotypes from Lake Superior and Great Bear Lake: Are fish really what they eat?
Louise Chavarie, John P. Hoffmann, A. M. Muir, C. C. Krueger, C.R. Bronte, K.L. Howland, S.P. Gallagher, S. P. Sitar, M.J. Hansen, Mark R. Vinson, L.F. Baker, L.L. Loseto, William M. Tonn, H. Swanson
2020, Canadian Journal of Fisheries and Aquatic Sciences (77) 1209-1220
Fatty acids are well-established biomarkers used to characterize trophic ecology, food-web linkages, and the ecological niche of many different taxa. Most often, fatty acids that are examined include only those previously identified as “dietary” or “extended dietary” biomarkers. Fatty acids considered as nondietary biomarkers, however, represent numerous fatty acids that...
Improved fish counting method accurately quantifies high‐density fish movement in dual‐frequency identification sonar data files from a coastal wetland environment
Michael R. Eggleston, Scott W. Milne, Maxwell Ramsay, Kurt P. Kowalski
2020, North American Journal of Fisheries Management (40) 883-892
There are many ways to quantify fish movement through shallow‐water habitats, but most noninvasive methods (e.g., visual counts) are not effective in turbid coastal wetland waters of the Great Lakes. Dual‐frequency identification sonar (DIDSON) technology (Sound Metrics) offers a noninvasive, hydroacoustic‐based approach to characterize fish movement in wetlands and other...

2020, Food and Chemical Toxicology (143)
Anticoagulant rodenticides are widely used for rodent control in agricultural and urban settings. Their intense use can sometimes result in accidental exposure and even poisoning of livestock. Can milk, eggs or meat derived from such accidentally exposed animals be consumed by humans? Data on the pharmacokinetics of chlorophacinone in milk...

Dakota M. Churchill, Michael Manga, Shaul Hurwitz, Sara Peek, Joseph Licciardi, James B. Paces
2020, Journal of Volcanology and Geothermal Research (402)
We describe a new effort to date hydrothermal silica sinter deposits (geyserite) from the Upper Geyser Basin of Yellowstone National Park using 14C of co-deposited organic matter, U-series and cosmogenic 10Be methods. A majority of the samples were collected from stratigraphic sections, mainly at Riverside, Giant, and Castle Geysers. Ages...

msocc: Fit and analyse computationally efficient multi‐scale occupancy models in R
Christian Stratton, Adam J. Sepulveda, Andrew B. Hoegh
2020, Methods in Ecology and Evolution (11) 1113-1120
Environmental DNA (eDNA) sampling is a promising tool for the detection of rare and cryptic taxa, such as aquatic pathogens, parasites and invasive species. Environmental DNA sampling workflows commonly rely on multi‐stage hierarchical sampling designs that induce complicated dependencies within the data. This complex dependence structure can be intuitively...

Joshua J. Picotte
2020, Conference Paper, Proceedings of the fire continuum- Preparing for the future of wildland fire
Accurate and complete geospatial fire occurrence records are important in determining postfire effects, emissions, hazards, and fuel loading inventories. Currently, the Monitoring Trends in Burn Severity (MTBS) project maps the fire perimeter and burn severity of all large fires on public lands. Although the MTBS project maps a large proportion...

2020, Seismological Research Letters (91) 2817-2827
We investigate the potential of using borehole strainmeter data from the Network of the Americas (NOTA) and the U.S. Geological Survey networks to estimate earthquake moment magnitudes for earthquake early warning (EEW) applications. We derive an empirical equation relating peak dynamic strain, earthquake moment magnitude, and hypocentral distance, and investigate...
Living on the edge: Multi-scale analyses of bird habitat use in coastal marshes of Barataria Basin, Louisiana, USA
Brett Patton, J. A. Nyman, Megan K. La Peyre
2020, Wetlands (40) 2041-2054
Coastal marsh loss, combined with expected sea-level rise, will cause inundation and extensive shifts to vegetation and salinity regimes that may affect the bird species dependent on coastal ecosystems worldwide. Within coastal marsh habitats, birds provide key targets for coastal management goals. However, limited information on bird-habitat relationships within coastal...

2020, The Mountain Geologist (57) 241-270
The eastern Snake River Plain (ESRP) is a northeast-trending topographic basin interpreted to be the result of the time-transgressive track of the North American plate above the Yellowstone hotspot. The track is defined by the age progression of silicic volcanic rocks exposed along the margins of the ESRP. However, the...

Brian D. Collins, Federica Sandrone, Laurent Gastaldo, Greg M. Stock, Michel Jaboyedoff
2020, Conference Paper, 54th US Rock Mechanics/Geomechanics Symposium
To explore connections between rock strength and rock falls, we undertook a comprehensive rock mechanics testing program for six granitic rock types in Yosemite Valley (California, USA) where rock falls are a common geomorphic and sometimes hazardous process. We collected samples from boulders located at the base of cliffs, with...
Mortality and cholinesterase inhibition in butterflies following aerial naled applications for mosquito control on the National Key Deer Refuge
Timothy Bargar, Chad Anderson, Anthony Sowers
2020, Archives of Environmental Contamination and Toxicology (79) 233-245
Natural resource managers are concerned about the impacts of aerial ultra-low volume spray (ULV) of insecticides for mosquito control (i.e., mosquito adulticides) and seek science-driven management recommendations that reduce risk but allow vector control for nearby human populations. Managers at the National Key Deer Refuge (Florida Keys, FL) are concerned...
Gambel’s quail survey variability and implications for survey design in the Mohave Desert
Cory T. Overton, Michael L. Casazza, Daniel Connelley, Scott C. Gardner
2020, Wildlife Society Bulletin (44) 493-501
Careful design of a wildlife population monitoring strategy is necessary to obtain accurate and precise results whether the purpose of the survey is development of habitat suitability models, to estimate abundance, or assess site occupancy. Important characteristics to consider in survey design are sources of elevated variability, particularly within‐subject variability,...

Jiaojiao Diao, Jinxun Liu, Zhiliang Zhu, Mingshi Li, Benjamin M. Sleeter
2020, Remote Sensing (12)
Quantifying land-use and land-cover change (LULCC) effects on carbon sources and sinks has been very challenging because of the availability and quality of LULCC data. As the largest estuary in the United States, Chesapeake Bay is a rapidly changing region and is affected by human activities. A new annual land-use...
