The Neogene Peters Hills basin is a small terrestrial basin that formed along the south flank of the Alaska Range during a time in which there was regional shortening. The formation of the Peters Hills basin is consistent with it being a wedge-top basin that formed on top of the...
Effectiveness of environmental flows for riparian restoration in arid regions: A tale of four rivers
Edward P. Glenn, Pamela L. Nagler, Patrick B. Shafroth, Christopher Jarchow
2017, Ecological Engineering (106) 695-703
Environmental flows have become important restoration tools on regulated rivers. However, environmental flows are often constrained by other demands within the river system and thus typically are comprised of smaller water volumes than the natural flows they are meant to replace, which can limit their functional efficacy. We review environmental flow programs...

Interactions of estuarine shoreline infrastructure with multiscale sea level variability
Ruo-Quian Wang, Liv M. Herdman, Li H. Erikson, Patrick L. Barnard, Michelle Hummel, Mark T. Stacey
2017, Journal of Geophysical Research: Oceans (122) 9962-9979
Sea level rise increases the risk of storms and other short‐term water‐rise events, because it sets a higher water level such that coastal surges become more likely to overtop protections and cause floods. To protect coastal communities, it is necessary to understand the interaction among multiday and tidal sea level...
Improvements in absolute seismometer sensitivity calibration using local earth gravity measurements
Robert Anthony, Adam T. Ringler, David C. Wilson
2017, Bulletin of the Seismological Society of America (108) 503-510
The ability to determine both absolute and relative seismic amplitudes is fundamentally limited by the accuracy and precision with which scientists are able to calibrate seismometer sensitivities and characterize their response. Currently, across the Global Seismic Network (GSN), errors in midband sensitivity exceed 3% at the 95% confidence interval and...

Sangchul Lee, Ali M. Sadeghi, In-Young Yeo, Gregory W. McCarty, W. Dean Hively
2017, Transactions of the American Society of Agricultural and Biological Engineers (60) 1939-1955
Winter cover crops (WCCs) have been widely implemented in the Coastal Plain of the Chesapeake Bay watershed (CBW) due to their high effectiveness at reducing nitrate loads. However, future climate conditions (FCCs) are expected to exacerbate water quality degradation in the CBW by increasing nitrate loads from agriculture....
Effects of lava heating on volatile-rich slopes on Io
Colin M. Dundas
2017, Journal of Geophysical Research E: Planets (122) 546-559
The upper crust of Io may be very rich in volatile sulfur and SO2. The surface is also highly volcanically active, and slopes may be warmed by radiant heat from the lava. This is particularly the case in paterae, which commonly host volcanic eruptions and long-lived lava lakes. Paterae slopes...

A general modeling framework for describing spatially structured population dynamics
Christine Sample, John Fryxell, Joanna A. Bieri, Paula Federico, Julia Earl, Ruscena Wiederholt, Brady J. Mattsson, Tyler Flockhart, Sam Nicol, James E. Diffendorfer, Wayne E. Thogmartin, Richard A. Erickson, D. Ryan Norris
2017, Ecology and Evolution (8) 493-508
Variation in movement across time and space fundamentally shapes the abundance and distribution of populations. Although a variety of approaches model structured population dynamics, they are limited to specific types of spatially structured populations and lack a unifying framework. Here, we propose a unified network-based framework sufficiently novel in its...
Host susceptibility to snake fungal disease is highly dispersed across phylogenetic and functional trait space
Frank T. Burbrink, Jeffrey M. Lorch, Karen R. Lips
2017, Science Advances (3)
Emerging infectious diseases (EIDs) reduce host population sizes, cause extinction, disassemble communities, and have indirect negative effects on human well-being. Fungal EIDs have reduced population abundances in amphibians and bats across many species over large areas. The recent emergence of snake fungal disease (SFD) may have caused declines in some...
Granular flows at recurring slope lineae on Mars indicate a limited role for liquid water
Colin M. Dundas, Alfred S. McEwen, Matthew Chojnacki, Moses P. Milazzo, Shane Byrne, Jim McElwaine, Anna Urso
2017, Nature Geoscience (10) 903-907
Recent liquid water flow on Mars has been proposed based on geomorphological features, such as gullies. Recurring slope lineae — seasonal flows that are darker than their surroundings — are candidate locations for seeping liquid water on Mars today, but their formation mechanism remains unclear. Topographical analysis shows that the...
