Sexing sirenians: Validation of visual and molecular sex determination in both wild dugongs (Dugong dugon) and Florida manatees (Trichechus manatus latirostris)
J. Lanyon, H. Sneath, J. Ovenden, D. Broderick, Robert K. Bonde
2009, Aquatic Mammals (35) 187-192
Sexing wild marine mammals that show little to no sexual dimorphism is challenging. For sirenians that are difficult to catch or approach closely, molecular sexing from tissue biopsies offers an alternative method to visual discrimination. This paper reports the results of a field study to validate the use of two...
Lysimetric Evaluation of Simplified Surface Energy Balance Approach in the Texas High Plains
Gabriel B. Senay, P.H. Gowda, T.A. Howell, T.H. Marek
2009, Applied Engineering in Agriculture (25) 665-669
Numerous energy balance (EB) algorithms have been developed to make use of remote sensing data to estimate evapotranspiration (ET) regionally. However, most EB models are complex to use and efforts are being made to simplify procedures mainly through the scaling of reference ET. The Simplified Surface Energy Balance (SSEB) is...

Since its establishment in 1903, the National Wildlife Refuge System (NWRS) has grown to 635 units and 37 Wetland Management Districts in the United States and its territories. These units provide the seasonal habitats necessary for migratory waterfowl and other species to complete their annual life cycles. Habitat conversion and...
Geochemistry of inorganic nitrogen in waters released from coal-bed natural gas production wells in the Powder River Basin, Wyoming
Richard L. Smith, Deborah A. Repert, Charles P. Hart
2009, Environmental Science & Technology (43) 2348-2354
Water originating from coal-bed natural gas (CBNG) production wells typically contains ammonium and is often disposed via discharge to ephemeral channels. A study conducted in the Powder River Basin, Wyoming, documented downstream changes in CBNG water composition, emphasizing nitrogen-cycling processes and the fate of ammonium. Dissolved ammonium concentrations from 19...

2009, Ecological Monographs (79) 523-555
The recent warming in the Arctic is affecting a broad spectrum of physical, ecological, and human/cultural systems that may be irreversible on century time scales and have the potential to cause rapid changes in the earth system. The response of the carbon cycle of the Arctic to changes in climate...
Efficacy of automatic vocalization recognition software for anuran monitoring
J. Hardin Waddle, Tyler F. Thigpen, Brad M. Glorioso
2009, Herpetological Conservation and Biology (4) 384-388
Surveys of vocalizations are a widely used method for monitoring anurans, but it can be difficult to coordinate standardized data collection across a large geographic area. Digital automated recording systems (ARS) offer a low-cost method for obtaining samples of anuran vocalizations, but the number of recordings can...

2009, Computers & Geosciences (35) 2304-2313
Spacecraft continue to send back extraordinary amounts of data from Mars leaving scientists with the considerable task of analyzing an ever-increasing wealth of information. There are abundant uses for coregistered topography and images, but coregistering various datasets can be time-consuming and labor-intensive. We have developed a set of C-shell Unix...

Direct calculation of the probability distribution for earthquake losses to a portfolio
Robert L. Wesson, David M. Perkins, Nico Luco, Erdem Karaca
2009, Earthquake Spectra (25) 687-706
We demonstrate a direct method for the calculation of the annual frequency of exceedance for earthquake losses (or the probability distribution for annual losses) to a portfolio. This method parallels the classic method of probabilistic seismic hazard analysis for the calculation of the annual frequency of exceedance for earthquake ground...

2009, Conference Paper, Field trip guidebook: New York State Geological Association 81st annual meeting, September 25-27, 2009
In this field trip, we provide a review of the significant controversy concerning the timing of deglaciation in the Hudson and Wallkill Valleys. We outline the differences in methodology and chronology with a circular route throughout the Hudson and Wallkill valleys. We begin the trip at Lake Mohonk near New...
Distribution of major anions and trace elements in the unsaturated zone at Franklin Lake Playa, California, USA
George N. Breit, Harland L. Goldstein, Richard L. Reynolds, James C. Yount
2009, Natural Resources and Environmental Issues (15)
The composition of surficial salts formed near dry and drying saline lakes are partly the product of processes active in the unsaturated zone between the ground surface and the water table. These processes were investigated by determining the abundance of water-extractable solutes in sediment from the ground surface to the...

Zoogeography, conservation, and ecology of crayfishes within the Cheat River basin of the Upper Monongehela River drainage, West Virginia
Stuart A. Welsh
2009, Proceedings of the West Virginia Academy of Science (81) 25-40
During summer 2008, we studied the geographic distribution and conservation status of crayfishes within the Cheat River basin of the upper Monongahela River drainage. Stream sites (n = 73) were selected with a probabilistic sampling design, whereas one reservoir (Cheat Lake) and seven terrestrial sites for burrowing crayfishes were selected...

Kevin A. Haas, John C. Warner
2009, Ocean Modelling (26) 91-103
Predictions of nearshore and surf zone processes are important for determining coastal circulation, impacts of storms, navigation, and recreational safety. Numerical modeling of these systems facilitates advancements in our understanding of coastal changes and can provide predictive capabilities for resource managers. There exists many nearshore coastal circulation models, however they...
