Can migration mitigate the effects of ecosystem change? Patterns of dispersal, energy acquisition and allocation in Great Lakes lake whitefish (Coregonus clupeaformis)
Michael D. Rennie, Mark P. Ebener, Tyler Wagner
2012, Advances in Limnology (63) 455-476
Migration can be a behavioural response to poor or declining home range habitat quality and can occur when the costs of migration are overcome by the benefi ts of encountering higher-quality resources elsewhere. Despite dramatic ecosystem-level changes in the benthic food web of the Laurentian Great Lakes since the colonization...

2012, Report, Louisiana’s Comprehensive Master Plan for a Sustainable Coast
The vegetation model (LAVegMod) described in this appendix is the next generation of a similar model (habitat switching module) initially developed as part of the Louisiana Coastal Area study. LAVegMod divides the original 5-habitat model for the Louisiana coast into 19 vegetation types. LAVegMod provides longer estimates of interannual variation...
Version 3.0 of EMINERS - Economic Mineral Resource Simulator
Joseph S. Duval
2012, Open-File Report 2004-1344
Quantitative mineral resource assessment, as developed by the U.S. Geological Survey (USGS), consists of three parts: (1) development of grade and tonnage mineral deposit models; (2) delineation of tracts permissive for each deposit type; and (3) probabilistic estimation of the numbers of undiscovered deposits for each deposit type. The estimate...

Real-time seismic monitoring of structures: Data handling and case studies
Mehmet Celebi
2011, Book chapter, Earthquake data in engineering seismology: Predictive models, data management and networks
Within the last decade, advances in the acquisition, processing and transmission of data from real-time seismic monitoring systems has contributed to the growth in the number structures instrumented with such systems. An equally important factor for such growth can be attributed to the demands by stakeholders to find rapid answers...

Julie D. Rosati, Ping Wang, Tiffany M. Roberts, editor(s)
2011, Book, The Proceedings of the Coastal Sediments 2011
Current regulations in California prohibit the disposal of more than 20% fine-grained sediment in the coastal zone; this threshold is currently being investigated to determine if this environmental regulation can be improved upon. A field monitoring and numerical modeling experiment took place late 2 009 to determine the fate...
Measuring the impacts of natural amenities and the US-Mexico Border, on housing values in the Santa Cruz Watershed, using spatially-weighted hedonic modeling
Gladys Amaya, Laura M. Norman, George Frisvold
2011, Conference Paper, Proceedings of Santa Cruz River Researchers' Day
Assessing the sustainability of International policy or urban development requires consideration of the impacts of these decisions on Ecosystem Services, or the values that humans receive from the ecosystem, including market-land price, environmental, and human well-being values. Hedonic modeling helps to identify the market land price, considering the price is...

2011, Conference Paper, 34th International Symposium on Remote Sensing of Environment: The GEOSS Era: Towards Operational Environmental Monitoring
Droughts occur repeatedly in the United States resulting in billions of dollars of damage. Monitoring and reporting on drought conditions is a necessary function of government agencies at multiple levels. A team of Federal and university partners developed a drought decision- support tool with higher spatial resolution relative to traditional...

J.V. Klump, D. N. Edgington, P.E. Sager, Dale M. Robertson
2011, Canadian Journal of Fisheries and Aquatic Sciences (54) 10-26
The tributaries of Green Bay have long been recognized as major sources of phosphorus in the Lake Michigan basin. The status of Green Bay as a sink or source of phosphorus for Lake Michigan proper has been less well defined. The bay receives nearly 70% of its annual load of...

2011, GIScience and Remote Sensing (48) 522-540
Landscape assessment of soil moisture is critical to understanding the hydrological cycle at the regional scale and in broad-scale studies of biophysical processes affected by global climate changes in temperature and precipitation. Traditional efforts to measure soil moisture have been principally restricted to in situ measurements, so remote sensing techniques are often...
Effects of grade control structures on fish passage, biological assemblages, and hydraulic environments in western Iowa streams: a multidisciplinary review
J.T. Thomas, M.E. Culler, D.C. Dermisis, Clay Pierce, A.N. Papanicolaou, T.W. Stewart, C.J. Larson
2011, River Research and Applications (29) 389-398
Land use changes and channelization of streams in the deep loess region of western Iowa have led to stream channel incision, altered flow regimes, increased sediment inputs, decreased habitat diversity and reduced lateral connectivity of streams and floodplains. Grade control structures (GCSs) are built in streams to prevent further erosion,...
An overview of estrogen-associated endocrine disruption in fishes: Evidence of effects on reproductive and immune physiology
Luke R. Iwanowicz, Vicki S. Blazer
2011, Conference Paper, Bridging America and Russia with shared perspectives on aquatic animal health: Proceedings of the Third Bilateral Conference between Russia and the United States
Simply and perhaps intuitively defined, endocrine disruption is the abnormal modulation of normal hormonal physiology by exogenous chemicals. In fish, endocrine disruption of the reproductive system has been observed worldwide in numerous species and is known to affect both males and females. Observations of biologically relevant endocrine disruption most commonly...

John F. Walker, Lauren E. Hay, Steven L. Markstrom, Michael D. Dettinger
2011, Earth Interactions (15) 1-16
The U.S. Geological Survey Precipitation-Runoff Modeling System (PRMS) model was applied to basins in 14 different hydroclimatic regions to determine the sensitivity and variability of the freshwater resources of the United States in the face of current climate-change projections. Rather than attempting to choose a most likely scenario from the...
On the contribution of reconstruction labor wages and material prices to demand surge
Anna H. Olsen, Keith A. Porter
2011, SESM 11-1
Demand surge is understood to be a socio-economic phenomenon of large-scale natural disasters, most commonly explained by higher repair costs (after a large- versus small-scale disaster) resulting from higher material prices and labor wages. This study tests this explanation by developing quantitative models for the cost change of sets, or...
Don't forget about the Christchurch earthquake: Lessons learned from this disaster
Michael W. Hamburger, Walter D. Mooney
2011, Earth Magazine (56) 24-26
In the aftermath of the devastating magnitude-9.0 earthquake and tsunami that struck the Tohoku region of Japan on March 11, attention quickly turned away from a much smaller, but also highly destructive earthquake that struck the city of Christchurch, New Zealand, just a few weeks earlier, on Feb. 22. Both...

James S. Sedinger, Jason L. Schamber, David H. Ward, Christopher A. Nicolai, Bruce Conant
2011, American Naturalist (178) E110-E123
We used observations of individually marked female black brant geese (Branta bernicla nigricans; brant) at three wintering lagoons on the Pacific coast of Baja California—Laguna San Ignacio (LSI), Laguna Ojo de Liebre (LOL), and Bahía San Quintín (BSQ)—and the Tutakoke River breeding colony in Alaska to assess hypotheses about carryover...
