Luke McGuire, Francis K. Rengers, Jason W. Kean, Dennis M. Staley, Hui Tang, Ann Youberg
2019, Conference Paper, Debris-flow hazards mitigation : mechanics, monitoring, modeling, and assessment ; proceedings of the Seventh International Conference on Debris-Flow Hazards Mitigation
The extreme heat from wildfire alters soil properties and incinerates vegetation, leading to changes in infiltration capacity, ground cover, soil erodibility, and rainfall interception. These changes promote increases in runoff and sediment transport that increase the likelihood of runoff-generated debris flows. Over a period of several years, referred to as...

Katherine R Barnhart, Francis K. Rengers, Ghent Jessica N, Gregory E. Tucker, Jeffrey A. Coe, Jason W. Kean, Joel B. Smith, Dennis M. Staley, William Kleiber, Ashton M Wiens
2019, Conference Paper, Debris-flow hazards mitigation : mechanics, monitoring, modeling, and assessment ; proceedings of the Seventh International Conference on Debris-Flow Hazards Mitigation
The Chalk Cliffs debris-flow site is a small headwater catchment incised into highly fractured and hydrothermally altered quartz monzonite in a semi-arid climate. Over half of the extremely steep basin is exposed bedrock. Debris flows occur multiple times per year in response to rainstorm events, typically during the summer monsoon...
Airborne waveform lidar simulator using the radiative transfer of a laser pulse
Minsu Kim
2019, Applied Sciences (9)
An airborne lidar simulator creates a lidar point cloud from a simulated lidar system, flight parameters, and the terrain digital elevation model (DEM). At the basic level, the lidar simulator computes the range from a lidar system to the surface of a terrain using the geomatics lidar equation. The simple...

2019, Science (364)
Kubelka et al. (Report, 9 November 2018, p. 680-683) claim that climate change has disrupted patterns of nest predation in shorebirds. They report that predation rates have increased since the 1950s, especially in the Arctic. We describe methodological problems with their analyses and argue that there is no solid statistical...

Benthic foraminiferal biotic events related to the Paleocene–Eocene Thermal Maximum along the California Margin
Kristin McDougall-Reid, Cedric M John
2019, Marine Micropaleontology (150)
The faunal expression of the Paleocene-Eocene Thermal Maximum (PETM) is well documented in deep-sea sediments. However, few studies have examined continental margin sections, especially active margins. The Moreno and Lodo formations, Central California, were deposited along the eastern margin of a north-south trending forearc basin on the convergent margin of...
Estimating the pressure-limited dynamic capacity and costs of basin-scale CO2 storage in a Saline Formation
Steven T. Anderson, Hossein Jahediesfanjani
2019, International Journal of Greenhouse Gas Control (88) 156-167
Deployment of carbon capture and storage (CCS) could be necessary to be able to satisfy baseload electricity demand, maintain diversity in the energy mix, and achieve mitigation of carbon dioxide (CO2) emissions at lowest cost (IPCC, 2015; U.S. DOE, 2016). If basin-, regional- or national-scale deployment of CCS is needed, it...

Qihong Dai, David Bunnell, James S. Diana, Steven A. Pothoven, Lauren A. Eaton, Timothy P. O’Brien, Richard Kraus
2019, Journal of Great Lakes Research (45) 830-839
Rainbow smelt (Osmerus mordax) is a key planktivore and prey fish in Lake Huron. Given the declining offshore productivity in the lake since the early 2000s, we described the energy content of rainbow smelt in 2017 across five different regions (North Channel, Georgian Bay, Saginaw Bay, northern main basin, southern...
Tourmaline boron and strontium isotope systematics reveal magmatic fluid pulses and external fluid influx in a giant iron oxide-apatite (IOA) deposit
Zhi-kun Su, Xinfu Zhao, Li-ping Zeng, Kui-dong Zhao, Albert H. Hofstra
2019, Geochimica et Cosmochimica Acta (259) 233-252
Tourmaline is a common boron-bearing mineral in hydrothermal system and has been widely used as a mineral probe to reconstruct geological processes because of its broad range in composition and resistance to metasomatic alteration. The origin of Kiruna-type iron oxide-apatite (IOA) deposits, commonly linked to andesitic subvolcanic or volcanic rocks, is highly controversial. Constraints...

2019, The Condor (120) 530-542
The most recent comprehensive estimates of Northern Spotted Owl (Strix occidentalis caurina) natal dispersal distances were reported in 2002. Since then, Northern Spotted Owl populations have experienced substantial demographic changes, with potential attendant changes in natal dispersal distances, including temporal or geographic trends. We analyzed the natal dispersal of Northern...

A general model of temporary aquatic habitat use: Water phenology as a life history filter
Kurt C. Heim, Jeffrey A. Falke, Thomas E. McMahon, Mark S. Wipfli, Leonardo Calle
2019, Fish and Fisheries (20) 802-816
Temporary aquatic habitats are not widely appreciated fish habitat. However, fish navigate the transient waters of intertidal zones, floodplains, intermittent and ephemeral streams, lake margins, seasonally frozen lakes and streams, and anthropogenic aquatic habitats across the globe to access important resources. The selective pressures imposed by water impermanence (i.e., freezing,...

Carolyn A. Morrow, Diane E. Moore, David A. Lockner, Barbara A. Bekins
2019, Book chapter, Proceedings of the International Ocean Discovery Program
Core samples from the International Ocean Discovery Program (IODP) Expedition 366 were tested in the laboratory to determine permeability, porosity, density, and frictional strength and their relation to mineralogy as part of an effort to understand hydro-mechanical processes at convergent plate margins. Seven samples were tested from a depth range...
Climate and disturbance influence self-sustaining stand dynamics of aspen (Populus tremuloides) near its range margin
Douglas J. Shinneman, Susan McIlroy
2019, Ecological Applications (29)
Species that are primarily seral may form stable (self-sustaining) communities under certain disturbance regimes or environmental conditions, yet such populations may also be particularly vulnerable to ecological change. Aspen (Populus spp.) are generally considered seral throughout the northern hemisphere, including P. tremuloides, the most widely distributed tree species in North...

Brian D. Uher-Koch, Joel A. Schmutz, Heather M. Wilson, R Michael Anthony, Thomas L Day, Thomas F Fondell, Brian T. Person, James S. Sedinger
2019, Ecosphere (10)
Grazing lawns, patches of grazing tolerant plants with high nutrient value, provide important habitat for herbivores, and changes in abundance can impact herbivore populations. Grazing lawns are maintained in quality and quantity by repeated grazing and are a result of a positive feedback since the availability of grazing lawn...

2019, Ecosphere (10)
Reestablishing shrub canopy cover after disturbance in semi-arid ecosystems, such as sagebrush steppe, is essential to provide wildlife habitat and restore ecosystem functioning. While several studies have explored the effects of landscape and climate factors on the success or failure of sagebrush seeding, the influence of soil properties on gradients...
