Stephanie A. Sparkman, Dianna M. Hogan, Kristina G. Hopkins, J. V. Loperfido
2017, Journal of the American Water Resources Association (53) 1081-1094
Stormwater runoff and associated pollutants from urban areas in the greater Chesapeake Bay Watershed (CBW) impair local streams and downstream ecosystems, despite urbanized land comprising only 7% of the CBW area. More recently, stormwater best management practices (BMPs) have been implemented in a low impact development (LID) manner to treat...

Joshuah S. Prekins, Keith B. Gido, Jeffrey A. Falke, Kurt D. Fausch, Harry Crockett, Eric R. Johnson, John Sanderson
2017, Proceedings of the National Academy of Sciences of the United States of America (114) 7373-7378
Groundwater pumping for agriculture is a major driver causing declines of global freshwater ecosystems, yet the ecological consequences for stream fish assemblages are rarely quantified. We combined retrospective (1950–2010) and prospective (2011–2060) modeling approaches within a multiscale framework to predict change in Great Plains stream fish assemblages associated with groundwater...

Maoya Bassiouni, Martha A. Scholl, Angel J. Torres-Sanchez, Sheila F. Murphy
2017, Agricultural and Forest Meteorology (243) 100-112
Quantifying the frequency, duration, and elevation range of fog or cloud immersion is essential to estimate cloud water deposition in water budgets and to understand the ecohydrology of cloud forests. The goal of this study was to develop a low-cost and high spatial-coverage method to detect occurrence of cloud immersion...

2017, Tectonics (36) 2085-2107
The Yakima folds of central Washington, USA, are prominent anticlines that are the primary tectonic features of the backarc of the northern Cascadia subduction zone. What accounts for their topographic expression and how much strain do they accommodate and over what time period? We investigate Manastash anticline, a north vergent...
Role of a naturally varying flow regime in Everglades restoration
Judson Harvey, Paul R. Wetzel, Thomas E. Lodge, Victor C. Engel, Michael S. Ross
2017, Restoration Ecology (25) S27-S38
The Everglades is a low-gradient floodplain predominantly on organic soil that undergoes seasonally pulsing sheetflow through a network of deepwater sloughs separated by slightly higher elevation ridges. The seasonally pulsing flow permitted the coexistence of ridge and slough vegetation, including the persistence of productive, well-connected sloughs that seasonally concentrated prey...

2017, Biological Journal of the Linnean Society (122) 133-146
Recent syntheses of phylogeographical data from terrestrial animals in the Mojave and Sonoran deserts have revealed a complex history of geologic and climatic vicariance events. We studied the phylogeography of Smeringurus vachoni to see how vicariance events may have impacted a large, endemic rock scorpion. Additionally, we used the phylogeographical data to...
