Experimental reintroduction of the federally endangered Santa Cruz Island bush mallow (Malacothamnus fasciculatus var. nestioticus)
D.H. Wilken, K. McEachern
2011, Conference Paper, Proceedings of the CNPS Conservation Conference, 17-19 Jan 2009
Studies of Malacothamnus fasciculatus var. nesioticus were begun in 1995 to understand its distribution, reproductive biology and ecological requirements. After 100+ years of depredation by sheep, two known populations of fewer than 20 plants each survived in 1995. Molecular studies showed that each of the two populations was composed of...

Viral hemorrhagic septicemia virus (VHSV) was first detected in the Laurentian Great Lakes in 2005 during a mortality event in the Bay of Quinte, Lake Ontario. Subsequent analysis of archived samples determined that the first known isolation of VHSV in the Laurentian Great Lakes was from a muskellunge Esox masquinongy...

Charles P. Madenjian, Edward S. Rutherford, Marc A. Blouin, Bryan J. Sederberg, Jeff R. Elliott
2011, North American Journal of Fisheries Management (31) 905-913
The cisco Coregonus artedi was one of the most important native prey fishes in Lake Michigan and in the other four Laurentian Great Lakes. Most of the cisco spawning in Lake Michigan was believed to have occurred in Green Bay. The cisco population in Lake Michigan collapsed during the 1950s,...
Patterns of acoustical activity of bats prior to and following White-nose Syndrome occurrence
W. Mark Ford, Eric R. Britzke, Christopher A. Dobony, Jane L. Rodrigue, Joshua B. Johnson
2011, Journal of Fish and Wildlife Management (2) 125-134
White-nose Syndrome (WNS), a wildlife health concern that has decimated cave-hibernating bat populations in eastern North America since 2006, began affecting source-caves for summer bat populations at Fort Drum, a U.S. Army installation in New York in the winter of 2007–2008. As regional die-offs of bats became evident, and Fort...
Estimating groundwater recharge
David A. Stonestrom
2011, Eos, Transactions, American Geophysical Union (92) 269-269
Groundwater recharge is the entry of fresh water into the saturated portion of the subsurface part of the hydrologic cycle, the modifier “saturated” indicating that the pressure of the pore water is greater than atmospheric. Briefly stated, recharge is downward flux across the water table. The term “groundwater recharge” can...

Jeffrey J. Duda, Jonathan A. Warrick, Christopher S. Magirl, editor(s)
2011, Scientific Investigations Report 2011-5120-3
The removal of two dams on the Elwha River will introduce massive volumes of sediment to the river, and this increase in sediment supply in the river will likely modify the shapes and forms of the river and coastal landscape downstream of the dams. This chapter provides the geologic and...
Occurrence and distribution of Asian carps in Louisiana
R. Glenn Thomas, Jill A. Jenkins, Jody David
2011, Book chapter, Invasive Asian Carps in North America
In the 1970s, commercial fishers reported sightings of grass carp Ctenopharyngodon idella in large rivers and associated backwaters of Louisiana; the first specimen in Louisiana Department of Wildlife and Fisheries' fishery independent sampling was recorded in 1976. Beginning in the early 1980s, commercial fishers noted increasing populations of bighead carp...

2011, Technical Report ER-200630
Laboratory studies and a field demonstration were conducted to determine the ability of the Snap Sampler to recover representative concentrations of several types of inorganic analytes from ground water. Analytes included non-metals, transition metals, alkaline earth metals, alkali metals, and a metalloid. In the laboratory studies, concentrations of analytes in...
Demonstration and validation of a regenerated cellulose dialysis membrane diffusion sampler for monitoring groundwater quality and remediation progress at DoD sites: Perchlorate and ordnance compounds

2011, Technical Report ER-200313
This final technical report documents the demonstration and validation of regenerated cellulose dialysis membrane diffusion samplers (RCDM samplers) for use in collecting groundwater samples for perchlorate and a suite of explosives compounds. This project, ER-0313, was funded by the Environmental Security Technology Certification Program (ESTCP). The primary objectives of the...
Guidance manual for forensic analysis of perchlorate in groundwater using chlorine and oxygen isotopic analyses
2011, Report
Increased health concerns about perchlorate (ClO4-) during the past decade and subsequent regulatory considerations have generated appreciable interest in source identification. The key objective of the isotopic techniques described in this guidance manual is to provide evidence concerning the origin of ClO4- in soils and groundwater and, more specifically, whether...

Hyperspectral remote sensing of wetland vegetation
Elijah Ramsey III, Amina Rangoonwala
2011, Book chapter, Hyperspectral Remote Sensing of Vegetation
Wetlands proportionally exert a higher influence on biogeochemical fluxes among the land, the atmosphere, and hydrologic systems than their 1% worldwide occurrence suggests [1]. Although their frequency of occurrence is low and their importance is high, wetlands continue to face high detrimental pressures from natural and human-induced...
