Groundwater-flow assessment of the Mississippi River Valley alluvial aquifer of northeastern Arkansas
John B. Czarnecki
2010, Scientific Investigations Report 2010-5210
The Mississippi River Valley alluvial aquifer is a water-bearing assemblage of gravels and sands that underlies about 32,000 square miles of Arkansas, Kentucky, Louisiana, Mississippi, Missouri, and Tennessee. Pumping of groundwater from the alluvial aquifer for agriculture started in the early 1900s in the Grand Prairie area for the irrigation...

2010, Fact Sheet 2010-3111
Aquatic ecosystems, from deep sea reefs and coastal marshes to freshwater springs and wetlands, are home to diverse assemblages of life. These commercially and ecologically important systems are part of our national heritage, and are often treasured places or refuges that protect rare or threatened species. In the water-rich Southeastern...
Drought Monitoring with VegDRI
Jesslyn F. Brown
2010, Fact Sheet 2010-3114
Drought strikes somewhere in the United States every year, turning green landscapes brown as precipitation falls below normal levels and water supplies dwindle. Drought is typically a temporary climatic aberration, but it is also an insidious natural hazard. It might last for weeks, months, or years and may have many...

Thunderstorms and flooding of August 17, 2007, with a context provided by a history of other large storm and flood events in the Black Hills area of South Dakota
Daniel G. Driscoll, Matthew J. Bunkers, Janet M. Carter, John F. Stamm, Joyce E. Williamson
2010, Scientific Investigations Report 2010-5187
The Black Hills area of western South Dakota has a history of damaging flash floods that have resulted primarily from exceptionally strong rain-producing thunderstorms. The best known example is the catastrophic storm system of June 9-10, 1972, which caused severe flooding in several major drainages near Rapid City and resulted...
Channel-conveyance capacity, channel change, and sediment transport in the lower Puyallup, White, and Carbon Rivers, western Washington
Jonathan A. Czuba, Christiana R. Czuba, Chistopher S. Magirl, Frank D. Voss
2010, Scientific Investigations Report 2010-5240
Draining the volcanic, glaciated terrain of Mount Rainier, Washington, the Puyallup, White, and Carbon Rivers convey copious volumes of water and sediment down to Commencement Bay in Puget Sound. Recent flooding in the lowland river system has renewed interest in understanding sediment transport and its effects on flow conveyance throughout...
The effects of raking on sugar pine mortality following prescribed fire in Sequoia and Kings Canyon National Parks, California, USA
Jonathan C. B. Nesmith, Kevin L. O’Hara, Phillip J. van Mantgem, Perry de Valpine
2010, Fire Ecology (6) 97-116
Prescribed fire is an important tool for fuel reduction, the control of competing vegetation, and forest restoration. The accumulated fuels associated with historical fire exclusion can cause undesirably high tree mortality rates following prescribed fires and wildfires. This is especially true for sugar pine (Pinus lambertiana Douglas), which is already negatively...
Summer microhabitat use by adult and young-of-year snail darters (Percina tanasi) in two rivers
M. J. Ashton, James B. Layzer
2010, Ecology of Freshwater Fish (19) 609-617
We characterised microhabitat availability and use by adult and young‐of‐year (YOY) snail darters (Percina tanasi Etnier 1976) while snorkelling in the French Broad and Hiwassee rivers, TN, USA. Both age groups of snail darters disproportionately used most microhabitat variables compared to their availability. Snail...

Seasonal ice and hydrologic controls on dissolved organic carbon and nitrogen concentrations in a boreal-rich fen
Evan S. Kane, Merritt R. Turetsky, Jennifer W. Harden, A. David McGuire, James Michael Waddington
2010, Journal of Geophysical Research G: Biogeosciences (115)
[1] Boreal wetland carbon cycling is vulnerable to climate change in part because hydrology and the extent of frozen ground have strong influences on plant and microbial functions. We examined the response of dissolved organic carbon (DOC) and total dissolved nitrogen (TDN) across an experimental manipulation of water table position...

Heather L. Bateman, Tom L. Dudley, Dan W. Bean, Steven M. Ostoja, Kevin R. Hultine, Michael J. Kuehn
2010, Ecological Restoration (28) 405-410
Throughout riparian areas of the southwestern United States, non-native saltcedar (also known as tamarisk; Tamarix spp.) can form dense, monotypic stands and is often reported to have detrimental effects on native plants and habitat quality (Everitt 1980; Shafroth et al. 2005). Natural resource managers of these riparian areas spend considerable...

Magma flux at Okmok Volcano, Alaska, from a joint inversion of continuous GPS, campaign GPS, and interferometric synthetic aperture radar
Juliet Biggs, Zhong Lu, T. Fournier, Jeffrey T. Freymueller
2010, Journal of Geophysical Research B: Solid Earth (115)
Volcano deformation is usually measured using satellite geodetic techniques including interferometric synthetic aperture radar (InSAR), campaign GPS, and continuous GPS. Differences in the spatial and temporal sampling of each system mean that most appropriate inversion scheme to determine the source parameters from each data set is different. Most studies either...
A generalized watershed disturbance-invertebrate relation applicable in a range of environmental settings across the continental United States
Jeffrey J. Steuer
2010, Urban Ecosystems (13) 415-424
It is widely recognized that urbanization can affect ecological conditions in aquatic systems; numerous studies have identified impervious surface cover as an indicator of urban intensity and as an index of development at the watershed, regional, and national scale. Watershed percent imperviousness, a commonly understood urban metric was used as...

Colonial nesting Yellow-crowned Night Herons on the San Antonio River Walk
Clint W. Boal
2010, Bulletin of the Texas Ornithological Society (43) 45-48
Yellow-crowned Night Herons (Nyctinassa violacea) typically nest as single pairs or in small colonies of about four pairs with high internest distances. They are also reported as susceptible to disturbance and to avoid habitat with high human use. However, some Yellowcrowned Night Herons habituate to human-dominated landscapes and nest in...
Invasive reptiles and amphibians: global perspectives and local solutions
R.N. Reed, F. Kraus
2010, Animal Conservation (13) 3-4
In the annals of invasive species biology, higher taxa such asmammals, plants and insects have received the lion’s shareof research attention, largely because many of these invadershave demonstrated a remarkable ability to degrade ecosys-tems and cause economic harm. Interest in invasive reptilesand amphibians (collectively ‘herpetofauna’, colloquially‘herps’) has historically lagged but...
