J.A. Warrick, J.A. Hatten, G.B. Pasternack, A.B. Gray, M.A. Goni, R. A. Wheatcroft
2012, Geological Society of America Bulletin
The occurrence of two wildfires separated by 31 yr in the chaparral-dominated Arroyo Seco watershed (293 km) of California provides a unique opportunity to evaluate the effects of wildfire on suspended-sediment yield. Here, we compile discharge and suspended-sediment sampling data from before and after the fires and show that the...

S. Mike Linhart, Jon F. Nania, Curtis L. Sanders Jr., Stacey A. Archfield
2012, Scientific Investigations Report 2012-5232
The U.S. Geological Survey (USGS) maintains approximately 148 real-time streamgages in Iowa for which daily mean streamflow information is available, but daily mean streamflow data commonly are needed at locations where no streamgages are present. Therefore, the USGS conducted a study as part of a larger project in cooperation with...

Ruth F. Schulte, Ryan D. Taylor, Nadine M. Piatak, Robert R. Seal II
2012, Scientific Investigations Report 2010-5070-E
A new descriptive stratiform chromite deposit model was prepared which will provide a framework for understanding the characteristics of stratiform chromite deposits worldwide. Previous stratiform chromite deposit models developed by the U.S. Geological Survey (USGS) have been referred to as Bushveld chromium, because the Bushveld Complex in South Africa is...

Occupancy in continuous habitat
Murray G. Efford, Deanna K. Dawson
2012, Ecosphere (3) 1-15
The probability that a site has at least one individual of a species ('occupancy') has come to be widely used as a state variable for animal population monitoring. The available statistical theory for estimation when detection is imperfect applies particularly to habitat patches or islands, although it is also used...

Sarah A. Sonsthagen, R. Terry Chesser, Douglas A. Bell, Carla J. Dove
2012, Ecology and Evolution (2) 1278-1295
We studied the influence of glacial oscillations on the genetic structure of seven species of white-headed gull that breed at high latitudes (Larus argentatus, L. canus, L. glaucescens, L. glaucoides, L. hyperboreus, L. schistisagus, and L. thayeri). We evaluated localities hypothesized as ice-free areas or glacial refugia in other Arctic...

2012, Wildlife Monographs (182)
Populations of Pacific common eiders (Somateria mollissima v-nigrum) on the Yukon-Kuskokwim Delta (YKD) in western Alaska declined by 50–90% from 1957 to 1992 and then stabilized at reduced numbers from the early 1990s to the present. We investigated the underlying processes affecting their population dynamics by collection and analysis of...

Incorporating movement patterns to improve survival estimates for juvenile bull trout
Tracy Bowerman, Phaedra Budy
2012, North American Journal of Fisheries Management (32) 1123-1136
Populations of many fish species are sensitive to changes in vital rates during early life stages, but our understanding of the factors affecting growth, survival, and movement patterns is often extremely limited for juvenile fish. These critical information gaps are particularly evident for bull trout Salvelinus confluentus, a threatened Pacific...

Difference infiltrometer: a method to measure temporally variable infiltration rates during rainstorms
John A. Moody, Brian A. Ebel
2012, Hydrological Processes (26) 3312-3318
We developed a difference infiltrometer to measure time series of non-steady infiltration rates during rainstorms at the point scale. The infiltrometer uses two, tipping bucket rain gages. One gage measures rainfall onto, and the other measures runoff from, a small circular plot about 0.5-m in diameter. The small size allows...

2012, SIAM News (45)
Environmental models are used to evaluate the fate of fertilizers in agricultural settings (including soil denitrification), the degradation of hydrocarbons at spill sites, and water supply for people and ecosystems in small to large basins and cities—to mention but a few applications of these models. They also play a role...
