Chesapeake bay watershed land cover data series
Frederick M. Irani, Peter R. Claggett
2010, Data Series 505
To better understand how the land is changing and to relate those changes to water quality trends, the USGS EGSC funded the production of a Chesapeake Bay Watershed Land Cover Data Series (CBLCD) representing four dates: 1984, 1992, 2001, and 2006. EGSC will publish land change forecasts based on observed...

Robert C. Milici, Joseph R. Hatch, Mark J. Pawlewicz
2010, International Journal of Coal Geology (82) 160-174
In 2002, the U.S. Geological Survey (USGS) assessed the technically recoverable, undiscovered coalbed-gas resources in the Appalachian basin and Black Warrior basin Assessment Provinces as about 15.5 trillion cubic feet. Although these resources are almost equally divided between the two areas, most of the production occurs within relatively small areas...
Comparison of turbidity to multi-frequency sideways-looking acoustic-Doppler data and suspended-sediment data in the Colorado River in Grand Canyon
Nicholas Voichick, David J. Topping
2010, Conference Paper, Proceedings of the Joint Federal Interagency Conference 2010: Hydrology and sedimentation for a changing future: existing and emerging issues
Water clarity is important to biologists when studying fish and other fluvial fauna and flora. Turbidity is an indicator of the cloudiness of water, or reduced water clarity, and is commonly measured using nephelometric sensors that record the scattering and absorption of light by particles in the water. Unfortunately, nephelometric...

A.A. Echelle, J.C. Hackler, Justin B. Lack, S. R. Ballard, J. Roman, S. F. Fox, David M. Leslie Jr., Ronald A. Van Den Bussche
2010, Conservation Genetics (11) 1375-1387
A previous mtDNA study indicated that female-mediated gene flow was extremely rare among alligator snapping turtle populations in different drainages of the Gulf of Mexico. In this study, we used variation at seven microsatellite DNA loci to assess the possibility of male-mediated gene flow, we augmented the mtDNA survey with...
Patch dynamics and the timing of colonization-abandonment events by male Kirtland’s Warblers in an early succession habitat
Deahn M. Donner, Christine Ribic, John R. Probst
2010, Biological Conservation (143) 1159-1167
Habitat colonization and abandonment affects the distribution of a species in space and time, ultimately influencing the duration of time habitat is used and the total area of habitat occupied in any given year. Both aspects have important implications to long-term conservation planning. The importance of patch isolation and area...

Soil quality assessment using weighted fuzzy association rules
Yue-Ju Xue, Shu-Guang Liu, Yue-Ming Hu, Jing Yang
2010, Pedosphere (20) 334-341
Fuzzy association rules (FARs) can be powerful in assessing regional soil quality, a critical step prior to land planning and utilization; however, traditional FARs mined from soil quality database, ignoring the importance variability of the rules, can be redundant and far from optimal. In this study, we developed a method...
