Ronald R. Charpentier, Troy A. Cook
2013, Open-File Report 2013-1001
Over the last decade, oil and gas well productivities were estimated using decline-curve analysis for thousands of wells as part of U.S. Geological Survey (USGS) studies of continuous (unconventional) oil and gas resources in the United States. The estimated ultimate recoveries (EURs) of these wells show great variability that was...
Wetland dynamics influence mid-continent duck recruitment
Michael J. Anteau, Aaron T. Pearse, Michael L. Szymankski
2013, Conference Paper, Proceedings of North American Duck Symposium and Workshop
Recruitment is a key factor influencing duck population dynamics. Understanding what regulates recruitment of ducks is a prerequisite to informed habitat and harvest management. Quantity of May ponds (MP) has been linked to recruitment and population size (Kaminski and Gluesing 1987, Raveling and Heitmeyer 1989). However, wetland productivity (quality) is...

A regional classification of the effectiveness of depressional wetlands at mitigating nitrogen transport to surface waters in the Northern Atlantic Coastal Plain
Scott W. Ator, Judith M. Denver, Andrew E. LaMotte, Andrew J. Sekellick
2013, Scientific Investigations Report 2012-5266
Nitrogen from nonpoint sources contributes to eutrophication, hypoxia, and related ecological degradation in Atlantic Coastal Plain streams and adjacent coastal estuaries such as Chesapeake Bay and Pamlico Sound. Although denitrification in depressional (non-riparian) wetlands common to the Coastal Plain can be a significant landscape sink for nitrogen, the effectiveness of...

Estimating transmission of avian influenza in wild birds from incomplete epizootic data: implications for surveillance and disease spreac
Viviane Henaux, Jane Parmley, Catherine Soos, Michael D. Samuel
2013, Journal of Applied Ecology (50) 223-231
Estimating disease transmission in wildlife populations is critical to understand host–pathogen dynamics, predict disease risks and prioritize surveillance activities. However, obtaining reliable estimates for free-ranging populations is extremely challenging. In particular, disease surveillance programs may routinely miss the onset or end of epizootics and peak prevalence, limiting...

Paul A. Bedrosian, Matthew K. Burgess, Tracy Nishikawa
2013, Near Surface Geophysics (11) 545-555
Within the south-western Mojave Desert, the Joshua Basin Water District is considering applying imported water into infiltration ponds in the Joshua Tree groundwater sub-basin in an attempt to artificially recharge the underlying aquifer. Scarce subsurface hydrogeological data are available near the proposed recharge site; therefore, time-domain electromagnetic (TDEM) data were...

Recently there has been considerable concern about declines in bee communities in agricultural and natural habitats. The value of pollination to agriculture, provided primarily by bees, is >$200 billion/year worldwide, and in natural ecosystems it is thought to be even greater. However, no monitoring program exists to accurately detect declines...
