Riparian vegetation along streams provides a suite of ecosystem services in rangelands and thus is the target of restoration when degraded by over-grazing, erosion, incision, or other disturbances. Assessments of restoration effectiveness depend on defensible monitoring data, which can be both expensive and difficult to collect. We present a method...
Stronger peak ground motion, beyond the threshold to initiate a response, does not lead to larger stream discharge responses to earthquakes
Christian H. Mohr, Michael Manga, David J. Wald
2018, Geophysical Research Letters (45) 6523-6531
The impressive number of stream gauges in Chile, combined with a suite of past and recent large earthquakes, makes Chile a unique natural laboratory to study several streams that recorded responses to multiple seismic events. We document changes in discharge in eight streams in Chile following two or more large...

2018, Canadian Journal of Fisheries and Aquatic Sciences (76) 753-761
The effect of climate change on stream temperature regimes is of significant concern to natural resource managers focused on protecting cold-water-dependent species. Nevertheless, understanding of how human land-use activities may act to exacerbate the effects of climate change on stream temperature regimes is limited. Using extensive stream temperature data with...
Outburst floods provide erodability estimates consistent with long-term landscape evolution
Daniel Garcia-Castellanos, Jim E. O'Connor
2018, Scientific Reports (8) 1-9
Most current models for the landscape evolution over geological timescales are based on semi-empirical laws that consider riverbed incision proportional to rock erodability (dependent on lithology) and to the work performed by water flow (stream power). However, the erodability values obtained from these models are entangled with poorly known conditions...

Dynamic minimum set problem for reserve design: Heuristic solutions for large problems
Mathieu Bonneau, Regis Sabbadin, Fred A. Johnson, Bradley Stith
2018, PLoS ONE (13)
Conversion of wild habitats to human dominated landscape is a major cause of biodiversity loss. An approach to mitigate the impact of habitat loss consists of designating reserves where habitat is preserved and managed. Determining the most valuable areas to preserve in a landscape is called the reserve design problem. There exists several...
Value of sample information in dynamic, structurally uncertain resource systems
Byron K. Williams, Fred A. Johnson
2018, PLoS ONE (13)
Few if any natural resource systems are completely understood and fully observed. Instead, there almost always is uncertainty about the way a system works and its status at any given time, which can limit effective management. A natural approach to uncertainty is to allocate time and effort to the collection...

Aaron Wech, Gabrielle Tepp, John J. Lyons, Matthew M. Haney
2018, Geophysical Research Letters (45) 6918-6925
The 2016‐2017 eruption of Bogoslof volcano, a submarine stratovolcano in the Bering Sea, produced 70 discrete explosive eruptions over 8 months. With no local monitoring data, activity was seismically recorded on nearby islands 50‐100 km away, limiting the detection and resolution of seismic observations. We construct a matched filter catalog...

Accurate predictions of microscale oxygen barometry in basaltic glasses using V K-edge X-ray absorption spectroscopy: A multivariate approach
Antonio Lanzirotti, M. Darby Dyar, Steve Sutton, Matthew Newville, Elisabet Head, CJ Carey, Molly McCanta, R. Lopaka Lee, Penelope L. King, John Jones
2018, American Mineralogist (103)
Because magmatic oxygen fugacity (fO2) exerts a primary control on the discrete vanadium (V) valence states that will exist in quenched melts, V valence proxies for fO2, measured using X-ray absorption near-edge spectroscopy (XANES), can provide highly sensitive measurements of the redox conditions in basaltic melts. However, published calibrations for basaltic...
