Effects of distributed and centralized stormwater best management practices and land cover on urban stream hydrology at the catchment scale
John V. Loperfido, Gregory B. Noe, S. Taylor Jarnagin, Dianna M. Hogan
2014, Journal of Hydrology (519) 2584-2595
Urban stormwater runoff remains an important issue that causes local and regional-scale water quantity and quality issues. Stormwater best management practices (BMPs) have been widely used to mitigate runoff issues, traditionally in a centralized manner; however, problems associated with urban hydrology have remained. An emerging trend is implementation of BMPs...

Jeffrey M. Lorch, Andrew M. Minnis, Carol U. Meteyer, Jennifer A. Redell, J. Paul White, Heather M. Kaarakka, Laura K. Muller, David L. Lindner, Michelle L. Verant, Valerie I. Shearn-Bochsler, David S. Blehert
2014, Journal of Wildlife Diseases (51) 36-47
Before the discovery of white-nose syndrome (WNS), a fungal disease caused by Pseudogymnoascus destructans, there were no reports of fungal skin infections in bats during hibernation. In 2011, bats with grossly visible fungal skin infections similar in appearance to WNS were reported from multiple sites in Wisconsin, USA, a state outside...

Laura E. Strickland, Richard G. Baker, Robert S. Thompson, Dane M. Miller
2014, Quaternary Research (82) 553-566
Ninety plant macrofossil taxa from the Ziegler Reservoir fossil site near Snowmass Village, Colorado, record environmental changes at high elevation (2705 m asl) in the Rocky Mountains during the Last Interglacial Period. Present-day vegetation is aspen forest (Populus tremuloides) intermixed with species of higher (Picea, Abies) and lower (Artemisia, Quercus) elevations. Stratigraphic units 4–13...
Diverse coral communities in mangrove habitats suggest a novel refuge from climate change
Kimberly K. Yates, Caroline S. Rogers, James J. Herlan, Gregg R. Brooks, Nathan A. Smiley, Rebekka A. Larson
2014, Biogeosciences (11) 4321-4337
Risk analyses indicate that more than 90% of the world's reefs will be threatened by climate change and local anthropogenic impacts by the year 2030 under "business-as-usual" climate scenarios. Increasing temperatures and solar radiation cause coral bleaching that has resulted in extensive coral mortality. Increasing carbon dioxide reduces seawater pH,...
A legacy of divergent fishery management regimes and the resilience of rainbow and cutthroat trout populations in Lake Crescent, Olympic National Park, Washington
Samuel J. Brenkman, Jeffrey J. Duda, Philip R. Kennedy, Bruce M. Baker
2014, Northwest Science (88) 280-304
As a means to increase visitation, early fisheries management in the National Park Service (NPS) promoted sport harvest and hatchery supplementation. Today, NPS management objectives focus on the preservation of native fish. We summarized management regimes of Olympic National Park's Lake Crescent, which included decades of liberal sport harvest and...
Does lake size matter? Combining morphology and process modeling to examine the contribution of lake classes to population-scale processes
Luke A. Winslow, Jordan S. Read, Paul C. Hanson, Emily H. Stanley
2014, Inland Waters (5) 7-14
With lake abundances in the thousands to millions, creating an intuitive understanding of the distribution of morphology and processes in lakes is challenging. To improve researchers’ understanding of large-scale lake processes, we developed a parsimonious mathematical model based on the Pareto distribution to describe the distribution of lake morphology (area,...

Daniel Rizzolo, Joel A. Schmutz, Sarah E. McCloskey, Thomas F. Fondell
2014, The Condor (116) 574-587
Red-throated Loon (Gavia stellata) numbers in Alaska have fluctuated dramatically over the past 3 decades; however, the demographic processes contributing to these population dynamics are poorly understood. To examine spatial and temporal variation in productivity, we estimated breeding parameters at 5 sites in Alaska: at Cape Espenberg and the Copper...

Katherine C. Malpeli, Peter G. Chirico
2014, The Extractive Industries and Society (1) 249-259
The Central African Republic (CAR), a country with rich diamond deposits and a tumultuous political history, experienced a government takeover by the Seleka rebel coalition in 2013. It is within this context that we developed and implemented a geospatial approach for assessing the lootability of high value-to-weight resource deposits, using...

Using vertical Fourier transforms to invert potential-field data to magnetization or density models in the presence of topography
Jeffrey Phillips
2014, Conference Paper, Society of Exploration Geophysicists, 2014 Technical Program Expanded Abstracts
A physical property inversion approach based on the use of 3D (or 2D) Fourier transforms to calculate the potential-field within a 3D (or 2D) volume from a known physical property distribution within the volume is described. Topographic surfaces and observations at arbitrary locations are easily accommodated. The limitations of the...
Optimally managing water resources in large river basins for an uncertain future
Edwin A. Roehl Jr., Paul Conrads
2014, Conference Paper, Proceedings of the 2014 South Carolina Water Resources Conference
Managers of large river basins face conflicting needs for water resources such as wildlife habitat, water supply, wastewater assimilative capacity, flood control, hydroelectricity, and recreation. The Savannah River Basin for example, has experienced three major droughts since 2000 that resulted in record low water levels in its reservoirs, impacting local...
Influence of fuels, weather and the built environment on the exposure of property to wildfire
Trent D. Penman, Luke S. Collins, Alexandra D. Syphard, Jon E. Keeley, Ross A. Bradstock
2014, PLoS ONE (9)
Wildfires can pose a significant risk to people and property. Billions of dollars are spent investing in fire management actions in an attempt to reduce the risk of loss. One of the key areas where money is spent is through fuel treatment – either fuel reduction (prescribed fire) or fuel...

2014, American Mineralogist (99) 2105-2115
This study of the spectral properties of Ca-sulfates was initiated to support remote detection of these minerals on Mars. Gypsum, bassanite, and anhydrite are the currently known forms of Ca-sulfates. They are typically found in sedimentary evaporites on Earth, but can also form via reaction of acidic fluids associated with...

2014, Book chapter, Impacts of Oil Spill Disasters on Marine Habitats and Fisheries in North America
On March 24, 1989, the tanker vessel Exxon Valdez altered its course to avoid floating ice, and ran aground on Bligh Reef in northeastern Prince William Sound (PWS), Alaska (Figure 1). The tanker was carrying about 53 million gallons of Prudhoe Bay crude, a heavy oil, and an estimated 11...
Dual-domain mass-transfer parameters from electrical hysteresis: Theory and analytical approach applied to laboratory, synthetic streambed, and groundwater experiments
Martin A. Briggs, Frederick D. Day-Lewis, John B. Ong, Judson W. Harvey, John W. Lane Jr.
2014, Water Resources Research (50) 8281-8299
Models of dual‐domain mass transfer (DDMT) are used to explain anomalous aquifer transport behavior such as the slow release of contamination and solute tracer tailing. Traditional tracer experiments to characterize DDMT are performed at the flow path scale (meters), which inherently incorporates heterogeneous exchange processes; hence, estimated “effective” parameters are...
The potential for sea-level-rise-induced barrier island loss: Insights from the Chandeleur Islands, Louisiana, USA
Laura J. Moore, Kiki Patsch, Jeffrey H. List, S. Jeffress Williams
2014, Marine Geology (355) 244-259
As sea level rises and hurricanes become more intense, barrier islands around the world become increasingly vulnerable to conversion from self-sustaining migrating landforms to submerging or subaqueous sand bodies. To explore the mechanism by which such state changes occur and to assess the factors leading to island disintegration, we develop...
