Carl J. Legleiter, Richard R. McDonald, Jonathan M. Nelson, Paul J. Kinzel, Ryan L. Perroy, Donghae Baek, Il Won Seo
2019, Journal of Ecohydraulics (4) 131-146
In river channels the flow field influences the dispersion of biota, contaminants, and other suspended or dissolved materials. Insight on patterns and rates of dispersion can be gained by injecting a pulse of visible dye and observing spatial and temporal variations in dye concentration as the pulse moves downstream. We...

Daniel D. Buscombe, Roxanne J Carini, Shawn Harrison, C Chris Chickadel, Jonathan A. Warrick
2019, Coastal Engineering (155)
We develop a remote wave gauging technique to estimate wave height and period from imagery of waves in the surf zone. In this proof-of-concept study, we apply the same framework to three datasets: the first, a set of close-range monochrome infrared (IR)...

Grady Ball, Kyle R. Douglas-Mankin
2019, Applied Engineering in Agriculture (5) 733-743
Large-scale assessments of rangeland runoff and erosion require methods to extend plot-scale parameterizations to large areas. In this study, Rangeland Hydrology and Erosion Model (RHEM) parameters were developed from plot-scale foliar and ground-cover transect data for an arid, grass-shrub rangeland in southern New Mexico, and a method was assessed to...

Advances in quantifying streamflow variability across continental scales: 2. Improved model regionalization and prediction uncertainties using hierarchical Bayesian methods
Richard B. Alexander, Gregory E. Schwarz, Elizabeth W. Boyer
2019, Water Resources Research (55) 11061-11087
The precise estimation of process effects in hydrological models requires applying models to large scales with extensive spatial variability in controlling factors. Despite progress in large‐scale applications of hydrological models in conterminous United States (CONUS) river basins, spatial constraints in model parameters have prevented the interbasin...
Historical range and variation (HRV)
Robert Keane, Rachel A. Loehman
2019, Book chapter, Encyclopedia of Wildfires and Wildland-Urban Interface (WUI) Fires
Fire-prone landscapes are experiencing rapid and potentially persistent changes as the result of complex and potentially novel interactions of anthropogenic climate changes, shifting fire regimes, exotic plant, insect, and pathogen invasions, and industrial, agricultural, and urban development. Are these landscapes fully departed from historical conditions? Should they be managed...
Simultaneous autoregressive (SAR) model
Mevin Hooten, Jay M. Ver Hoef, Ephraim M. Hanks
2019, Book chapter, Wiley StatsRef: Statistics reference online
Simultaneous autoregressive (SAR) models are useful for accommodating various forms of dependence among data that have discrete support in a space of interest. These models are often specified hierarchically as mixed-effects regression models with first-moment structure controlled by a conventional linear regression term and second-moment structure induced by correlated random...

This allows users to spend more time on analysis and less time on downloading, formatting, and...
Using stream-side groundwater discharge for geochemical exploration in mountainous terrain
Andrew H. Manning, Jean M. Morrison, Richard B. Wanty, Christopher T. Mills
2019, Journal of Geochemical Exploration (209)
Groundwater chemistry has been predominantly used in geochemical exploration studies to identify mineralized targets concealed under transported cover in areas with gentle topography. Another potentially valuable ap-plication that has received little attention is using groundwater chemistry to identify deposits concealed within mountain ridges. A number of geochemical exploration studies have...
Adult monarch (Danaus plexippus) abundance is higher in burned sites than in grazed sites
Julia B. Leone, Diane L. Larson, Jennifer L. Larson, Patrick Pennarola, Karen Oberhauser
2019, Frontiers in Ecology and Evolution (7)
Much of the remaining suitable habitat for monarchs (Danaus plexippus) in Minnesota is found in tallgrass prairies. We studied the association of adult monarch abundance with use of fire or grazing to manage prairies. Sites (n=20) ranged in size from 1 to 145 hectares and included land owned and managed...
The power, potential, and pitfalls of open access biodiversity data in range size assessments: Lessons from the fishes
Abigail Benson
2019, Ecological Indicators (110)
Geographic rarity is a driver of a species’ intrinsic risk of extinction. It encompasses multiple key components including range size, which is one of the most commonly measured estimates of geographic rarity. Range size estimates are often used to prioritize conservation efforts when there are multiple candidate species, because data...

The U.S. Geological Survey, in cooperation with the Missouri Department of Natural Resources, designed and operates a network of monitoring stations on streams and springs throughout Missouri known as the Ambient Water-Quality Monitoring Network. During water year 2018 (October 1, 2017, through September 30, 2018), water-quality data were collected at...
Pre‐fire vegetation drives post‐fire outcomes in sagebrush ecosystems: Evidence from field and remote sensing data
Brittany S. Barker, David S. Pilliod, Matthew Rigge, Collin G. Homer
2019, Ecosphere (10)
Understanding the factors that influence vegetation responses to disturbance is important because vegetation is the foundation of food resources, wildlife habitat, and ecosystem properties and processes. We integrated vegetation cover data derived from field plots and remotely sensed Landsat images in two focal areas over a 37‐yr period (1979–2016) to...
Standardized IMGT nomenclature of salmonidae IGH genes, the paradigm of Atlantic salmon and rainbow trout: From genomics to repertoires
Susana Magadan, Aleksei Krasnov, Saida Hadi-Saljoki, Sergey Afanasyev, Stanislas Mondot, Rosario Castro, Irene Salinas, Oriol Sunyer, John D. Hansen, Ben F Koop, Marie-Paule Lefranc, Pierre Boudinot
2019, Frontiers in Immunology (10)
In teleost fish as in mammals, humoral adaptive immunity is based on B lymphocytes expressing highly diverse immunoglobulins (IG). During B cell differentiation, IG loci are subjected to genomic rearrangements of V, D, and J genes, producing a unique antigen receptor expressed on the surface of each lymphocyte. During the...
The importance of natural versus human factors for ecological conditions of streams and rivers
Tao Tang, R. Jan Stevenson, James Grace
2019, Science of the Total Environment (704)
Streams are influenced by watershed-scale factors, such as climate, geology, topography, hydrology, and soils, which mostly vary naturally among sites, as well as human factors, agriculture and urban development. Thus, natural factors could complicate assessment of human disturbance. In the present study, we use structural equation modeling and data from...

Paige E. Howell, Blake R. Hossack, Erin L. Muths, Brent Sigafus, A Chenevert-Steffler, Richard B. Chandler
2019, Ecological Applications (30)
Conservation of at‐risk species is aided by reliable forecasts of the consequences of environmental change and management actions on population viability. Forecasts from conventional population viability analysis (PVA) are made using a two‐step procedure in which parameters are estimated, or elicited from expert opinion, and then...
Simple metrics predict salt-marsh sediment fluxes
Daniel J. Nowacki, Neil K. Ganju
2019, Geophysical Research Letters (46) 12250-12257
The growth (or decay) of salt marshes depends on suspended-sediment flux into and out of the marsh. Suspended-sediment concentration (SSC) is a key element of the flux, and SSC-based metrics reflect the long-term sediment-flux trajectories of a variety of salt marshes. One metric, the flood–ebb SSC differential, correlates with area-normalized...

Christopher DuRoss, Michael P. Bunds, Ryan D. Gold, Richard W. Briggs, Nadine G. Reitman, Stephen Personius, Nathan A. Toke
2019, Geosphere (15) 1869-1892
The 1983 Mw 6.9 Borah Peak earthquake generated ∼36 km of surface rupture along the Thousand Springs and Warm Springs sections of the Lost River fault zone (LRFZ, Idaho, USA). Although the rupture is a well-studied example of multisegment surface faulting, ambiguity remains regarding the degree to which a bedrock...
