Animal movement models with mechanistic selection functions
Mevin Hooten, Xinyi Lu, Martha J. Garlick, James A. Powell
2020, Spatial Statistics (37)
A suite of statistical methods are used to study animal movement. Most of these methods treat animal trajectory data in one of three ways: as discrete pro- cesses, as continuous processes, or as point processes. We brie y review each of these approaches and then focus in on the latter. In the context of...

Building on a geology-based assessment of undiscovered, technically recoverable petroleum resources in the Eagle Ford Group in south Texas, the U.S. Geological Survey has estimated the required water and proppant demands and formation water production volumes associated with possible future development of these petroleum resources. The results of the water...
Lesser prairie-chicken (Tympanuchus pallidicinctus) use of man-made water sources
Trevor S. Gicklhorn, Clint W. Boal, Philip K. Borsdorf
2020, Southwestern Naturalist (65) 197-204
The lesser prairie-chicken (Tympanuchus pallidicinctus) occurs in the semiarid southern Great Plains, a region prone to periods of drought. Researchers generally believe that lesser prairie-chickens are able to satisfy their water requirements through preformed water and metabolic processes, but also know that they experience low survival and reproductive success during...

Whereas our primary goal is to improve our operational capabilities of the USGS National Earthquake Information Center, the science, software,...
An exploration of parametric earthquake risk transfer solutions that dynamically adapt to seismicity changes
Guillermo Franco, R Guidotti, Edward H. Field, K.R. Milner, Y.J. Lee, R. S. Stein
2020, Conference Paper
(Re)insurance companies rely on earthquake risk models to estimate the frequency and severity of their potential financial losses. To protect themselves, they sometimes use parametric risk transfer solutions, which are derivative-form agreements that provide compensation as a function of routine measurable earthquake characteristics. These mechanisms typically remain in force for...
Decision context as an essential component of population viability analysis
Abigail Jean Lawson, Brian Folt, Anna Maureen Tucker, Francesca T. Erickson, Conor P. McGowan
2020, Conservation Biology 1683-1685
Population viability analysis (PVA) is a widely used tool that applies demographic data in simulation frameworks to assess extinction risk for species or populations. It is used in diverse conservation applications, including evaluating management effectiveness, relative risk of threats, and potential changes to protective status (Beissinger & McCullough, <a id="#cobi13818-bib-0002R" class="bibLink...

Juvenile Coho and Chinook salmon growth, size, and condition linked to watershed-scale salmon spawner abundance
Philip J. Joy, Craig A. Stricker, Renae Ivanoff, Shiao Y. Wang, Mark S. Wipfli, Andrew C. Seitz, Jiaqi Huang, Mathew B. Tyers
2020, Transactions of the American Fisheries Society (150) 307-326
Anadromous Pacific salmon Oncorhynchus spp. are semelparous, and resource subsidies from spawning adult salmon (marine-derived nutrients [MDN]) benefit juvenile salmonids while they rear in freshwater. However, it is unclear if juvenile salmon populations respond predictably to the abundance of spawning salmon at the watershed scale. To address whether hypothesized benefits to rearing...

Jeffrey A. Coe, Erin K. Bessette-Kirton, Dianne L. Brien, Mark E. Reid
2020, Conference Paper, Proceedings of the 13th International Symposium on Landslides
On September 20, 2017, Hurricane Maria triggered widespread debris flows in Puerto Rico. We used field observations and pre- and post-Maria lidar to study the volumetric growth of long-travelled (>400 m) debris flows in four basins. We found overall growth rates that ranged from 0.7 to 30.4 m3 per meter...

Quantifying microplastics in Indiana’s Lake Michigan watershed and submerged aquatic vegetation
Julie R. Peller, Meredith B. Nevers, Muruleedhara Byappanahalli, Mary Anne Evans
2020, Newsletter
Environmental breakdown of plastics produces synthetic microfibers, a class of microplastics that are most prevalent in surface waters. A main source of these pollutants is wastewater treatment plants which discharge into surface waters, including those that flow into Lake Michigan. Microplastics can settle into aquatic sediment or exist for lengths...

Testing hypotheses on signatures of precipitation variability in the river and floodplain deposits of the Paleogene San Juan Basin, New Mexico, USA
Kristine L. Zellman, Piret Plink-Bjorklund, Henry Fricke
2020, Journal of Sedimentary Research (90) 1770-1801
Much progress has been made in recent years towards a set of recognition criteria for river discharge variability in river channel deposits, and thus sedimentary proxies for precipitation variability. Despite this progress, there is currently no consensus on how different styles of discharge variability are reflected in river sedimentary records,...

Pamela J. Lombard, Janet R. Barclay, Dee-Ann E. Crozier
2020, Open-File Report 2020-1148
Below average and infrequent rainfall from May through September 2020 led to an extreme hydrologic drought across much of New England, with some areas experiencing a flash drought, reflecting its quick onset. The U.S. Geological Survey (USGS) recorded record-low streamflow and groundwater levels throughout the region. In September, the U.S....

Amina Rangoonwala, Rebecca J. Howard, Elijah W. Ramsey III
2020, Open-File Report 2020-1131
In response to a co-occurring non-native scale infestation and Phragmites australis dieback in southeast Louisiana, normalized difference vegetation index (NDVI) satellite mapping was implemented to track P. australis condition in the lower Mississippi River Delta. While the NDVI mapping successfully documented relative condition changes, identification of cause required a quantitative-biophysical...
