A model for evaluating stream temperature response to climate change scenarios in Wisconsin
Stephen M. Westenbroek, Jana S. Stewart, Cheryl A. Buchwald, Matthew G. Mitro, John D. Lyons, Steven Greb
2010, Conference Paper, Watershed Management 2010: Innovations in Watershed Management under Land Use and Climate Change
Global climate change is expected to alter temperature and flow regimes for streams in Wisconsin over the coming decades. Stream temperature will be influenced not only by the predicted increases in average air temperature, but also by changes in baseflow due to changes in precipitation patterns and amounts. In order...

Habitat use by Least Bitterns in the Arkansas Delta
Michael J. Budd, David G. Krementz
2010, Waterbirds (33) 140-147
Least Bittern (Ixobrychus exilis) occupancy surveys were conducted in the Arkansas Delta, USA, during April-July 2005-2006 to determine the proportion of area occupied and relate occupancy to habitat characteristics. Previous large-scale surveys indicated few Least Bitterns were present in the Delta. During surveys at 190 sites, Least Bitterns were detected...
Anchoring submersible ultrasonic receivers in river channels with stable substrate
Phillip William Bettoli, G.D. Scholten, D. Hubbs
2010, North American Journal of Fisheries Management (4) 989-992
We developed an anchoring system for submersible ultrasonic receivers (SURs) that we placed on the bottom of the riverine reaches of three main-stem reservoirs in the upper Tennessee River. Each anchor consisted of a steel tube (8.9 x 35.6 cm) welded vertically to a round plate of steel (5.1 x...
Dispersal of smallmouth bass from a simulated tournament weigh-in site
Melissa A. Kaintz, Phillip William Bettoli
2010, North American Journal of Fisheries Management (30) 976-982
Simulated smallmouth bass Micropterus dolomieu fishing tournaments were staged in Dale Hollow Lake, a 12,400-ha reservoir in Tennessee, between March 2004 and February 2005 to investigate posttournament dispersal. Smallmouth bass (n = 54) were captured with conventional hook-and-line tackle and artificial lures, placed in live wells, and subjected to a...

The source data set for wet deposition was from the USGS's raster data set atmospheric (wet) deposition of...
Submarine mass transport within Monterey Canyon: Benthic disturbance controls on the distribution of chemosynthetic biological communities
Charles K. Paull, B. Schlining, W. Ussler III, E. Lundsten, James P. Barry, D. W. Caress, D. E. Johnson, Mary McGann
David C. Mosher, Craig Shipp, Lorena Moscardelli, Jason Chaytor, Christopher D. P. Baxter, Homa J. Lee, Roger Urgeles, editor(s)
2010, Book chapter, Submarine mass movements and their consequences
Documenting mass transport within Monterey Canyon and Fan has been a focus of remotely operated vehicle (ROV) observations, sampling, monitoring, and multibeam mapping studies. These efforts indicate that major mass transport events occur within upper Monterey Canyon (<2 km water depths) with a sub-annual recurrence frequency. However, 14C-stratigraphies indicate that a...

Jeffrey M. Black, Carol Gress, Jacob W. Byers, Emily Jennings, Craig R. Ely
2010, Wildfowl (60) 38-51
Tundra Swan Cygnus columbianus columbinanus phenology and behaviour at the Eel River delta and southern Humboldt Bay in northern California, USA, is described. Counts made each January from 1963 onwards peaked at 1,502 swans in 1988. Monthly counts recorded during the 2006/07 and 2008/09 winters peaked in February, at 1,033...
Frequency domain, waveform inversion of laboratory crosswell radar data
Karl J. Ellefsen, Aldo T. Mazzella, Robert Horton, Jason R. McKenna
2010, Book, SEG technical program expanded abstracts 2010
A new waveform inversion for crosswell radar is formulated in the frequency-domain for a 2.5D model. The inversion simulates radar waves using the vector Helmholtz equation for electromagnetic waves. The objective function is minimized using a backpropagation method suitable for a 2.5D model. The inversion is tested by processing crosswell...
Observations of drainage network change in a recently burned watershed using terrestrial laser scanning
Dennis Staley, Thad Wasklewicz, Jason Kean
2010, Conference Paper, EGU General Assembly 2010
Wildfire enhances the geomorphic response of a watershed to precipitation events, effectively altering the form of the hillslope and channel drainage network. Typically, drainage networks expand following rainfall on a recently burned watershed. Expansion of drainage networks following wildfire increases in erosion and sediment transport rates, and the probability of...

Disease limits populations: plague and black-tailed prairie dogs
Jack F. Cully Jr., T. Johnson, S.K. Collinge, C. Ray
2010, Vector-Borne and Zoonotic Diseases (10) 7-15
Plague is an exotic vector-borne disease caused by the bacterium Yersinia pestis that causes mortality rates approaching 100% in black-tailed prairie dogs (Cynomys ludovicianus). We mapped the perimeter of the active portions of black-tailed prairie dog colonies annually between 1999 and 2005 at four prairie dog colony complexes in areas...

D.G. Trested, Reuben R. Goforth, J.P. Kirk, J. Jeffery Isely
2010, North American Journal of Fisheries Management (30) 121-125
The development of effective and minimally invasive techniques to determine gender and gonad developmental stage is particularly important in performing accurate fisheries assessments for use in conservation and restoration. The initial and latent survival of shovelnose sturgeon Scaphirhynchus platorynchus was assessed after exposure to a modified endoscopic technique designed to collect that...

S. Pierluissi, Sammy L. King, Michael D. Kaller
2010, Waterbirds (33) 323-330
Rice fields in southwestern Louisiana provide breeding habitat for several waterbird species; however, little is known about nest density, nest survival and the importance of landscape context of rice fields in determining breeding activity. In 2004, 42 rice fields were searched for nests, and 40 were searched in 2005. Land...

J. Carlos Santamarina, Carolyn D. Ruppel
Michael Riedel, Eleanor C. Willoughby, Satinder Chopra, editor(s)
2010, Book chapter, Geophysical characterization of gas hydrates
Proper understanding of the physical properties of hydrate-bearing sediments is required for interpretation of borehole logs and exploration geophysical data, the analysis of borehole and submarine slope stability, and the formulation of reservoir simulation and production models. Yet current knowledge of geophysical and geotechnical properties of hydrate-bearing sediments is still...
