Brandon S. Clayton, Stephen H. Hartzell, Morgan P. Moschetti, Sarah E. Minson
2017, Bulletin of the Seismological Society of America (107) 1526-1544
Inverting geophysical data has provided fundamental information about the behavior of earthquake rupture. However, inferring kinematic source model parameters for finite‐fault ruptures is an intrinsically underdetermined problem (the problem of nonuniqueness), because we are restricted to finite noisy observations. Although many studies use least‐squares techniques to make the finite‐fault problem...
Biogenic non-crystalline U(IV) revealed as major component in uranium ore deposits
Amrita Bhattacharyya, Kate M. Campbell, Shelly Kelly, Yvonne Roebbert, Stefan Weyer, Rizlan Bernier-Latmani, Thomas Borch
2017, Nature Communications (8)
Historically, it is believed that crystalline uraninite, produced via the abiotic reduction of hexavalent uranium (U(VI)) is the dominant reduced U species formed in low-temperature uranium roll-front ore deposits. Here we show that non-crystalline U(IV) generated through biologically mediated U(VI) reduction is the predominant U(IV) species in an undisturbed U roll-front ore deposit...

Jarrett Pfrimmer, Larry M. Gigliotti, Joshua Stafford, David Schumann, Katie Bertrand
2017, Human Dimensions of Wildlife (22) 382-389
The Conservation Reserve Enhancement Program (CREP) targets high-priority conservation needs (e.g., water quality, wildlife habitat) by paying landowners an annual rental rate to remove environmentally sensitive or agriculturally unproductive lands from rowcrop production, and then implement conservation practices on these lands. This study examined motivations of South Dakota landowners for...
Is motivation important to brook trout passage through culverts?
Elsa Goerig, Theodore R. Castro-Santos
2017, Canadian Journal of Fisheries and Aquatic Sciences (74) 885-893
Culverts can restrict movement of stream-dwelling fish. Motivation to enter and ascend these structures is an essential precursor for successful passage. However, motivation is challenging to quantify. Here, we use attempt rate to assess motivation of 447 brook trout (Salvelinus fontinalis) entering three culverts under a range of hydraulic, environmental,...

2017, Journal of Fish and Wildlife Management (8) 101-113
Pacific lamprey (Entosphenus tridentatus), an anadromous ectoparasite, faces several challenges during adult migration to spawning grounds. Developing methods to address these challenges is critical to the success of ongoing conservation efforts. The challenges are diverse, and include anthropogenic alterations to the ecosystem resulting in loss of habitat, impassable barriers such...
Reflected stochastic differential equation models for constrained animal movement
Ephraim M. Hanks, Devin S. Johnson, Mevin Hooten
2017, Journal of Agricultural, Biological, and Environmental Statistics (22) 353-372
Movement for many animal species is constrained in space by barriers such as rivers, shorelines, or impassable cliffs. We develop an approach for modeling animal movement constrained in space by considering a class of constrained stochastic processes, reflected stochastic differential equations. Our approach generalizes existing methods for modeling unconstrained animal...
The greenscape shapes surfing of resource waves in a large migratory herbivore
Ellen O. Aikens, Matthew J. Kauffman, Jerod Merkle, Samantha Dwinnell, Gary L. Fralick, Kevin L. Monteith
2017, Ecology Letters (20) 741-750
The Green Wave Hypothesis posits that herbivore migration manifests in response to waves of spring green-up (i.e. green-wave surfing). Nonetheless, empirical support for the Green Wave Hypothesis is mixed, and a framework for understanding variation in surfing is lacking. In a population of migratory mule deer (Odocoileus hemionus), 31% surfed...
Alternative foraging strategies enable a mountain ungulate to persist after migration loss
Alyson B. Courtemanch, Matthew J. Kauffman, Steve Kilpatrick, Sarah Dewey
2017, Ecosphere (8) 1-16
The persistence of many migratory ungulate populations worldwide is threatened due to anthropogenic impacts to seasonal ranges and migration routes. While many studies have linked migratory ungulate declines to migration disruption or loss, very few have explored the underlying factors that determine whether a population perishes or persists. In some...
A new mechanistic approach for the further development of a population with established size bimodality
Lisa Heerman, Donald L. DeAngelis, Jost Borcherding
2017, PLoS ONE (12) 1-18
Usually, the origin of a within-cohort bimodal size distribution is assumed to be caused by initial size differences or by one discrete period of accelerated growth for one part of the population. The aim of this study was to determine if more continuous pathways exist allowing shifts from the small...
Length limits fail to restructure a Largemouth Bass population: A 28‐year case history
Leandro E. Miranda, M.E. Colvin, A. C. Shamaskin, L. A. Bull, T. Holman, R. Jones
2017, North American Journal of Fisheries Management (37) 624-632
Length limits have been implemented by fisheries management agencies to achieve population density, size structure, and angler satisfaction objectives. By redirecting harvest towards or away from particular length‐ or age‐groups, length limits rely on harvest by anglers to maintain a population at or near a desired state. The fish population...

2017, Journal of Avian Biology (48) 815-826
The Gulf of Mexico is a conspicuous feature of the Neotropical–Nearctic bird migration system. Traveling long distances across ecological barriers comes with considerable risks, and mortality associated with intercontinental migration may be substantial, including that caused by storms or other adverse weather events. However, little, if anything, is known about...
Habitat models to predict wetland bird occupancy influenced by scale, anthropogenic disturbance, and imperfect detection
Wesley J. Glisson, Courtney J. Conway, Christopher P. Nadeau, Kathi L. Borgmann
2017, Ecosphere (8) 1-20
Understanding species–habitat relationships for endangered species is critical for their conservation. However, many studies have limited value for conservation because they fail to account for habitat associations at multiple spatial scales, anthropogenic variables, and imperfect detection. We addressed these three limitations by developing models for an endangered wetland bird, Yuma...
Calculation of in situ acoustic sediment attenuation using off-the-shelf horizontal ADCPs in low concentration settings
Dan Haught, Jeremy G. Venditti, Scott Wright
2017, Water Resources Research (53) 5017-5037
The use of “off-the-shelf” acoustic Doppler velocity profilers (ADCPs) to estimate suspended sediment concentration and grain-size in rivers requires robust methods to estimate sound attenuation by suspended sediment. Theoretical estimates of sediment attenuation require a priori knowledge of the concentration and grain-size distribution (GSD), making the method impractical to apply...
