This review and update was conducted by an international team (SR-SAG2) drawn from both the biological...
Intrinsic variability in shell and soft tissue growth of the freshwater mussel Lampsilis siliquoidea
James H. Larson, Nathan L. Eckert, Michelle Bartsch
2014, PLoS ONE (9)
Freshwater mussels are ecologically and economically important members of many aquatic ecosystems, but are globally among the most imperiled taxa. Propagation techniques for mussels have been developed and used to boost declining and restore extirpated populations. Here we use a cohort of propagated mussels to estimate the intrinsic variability in...
Persistence of DNA in carcasses, slime and avian feces may affect interpretation of environmental DNA data
Christopher M. Merkes, S. Grace McCalla, Nathan R. Jensen, Mark P. Gaikowski, Jon J. Amberg
2014, PLoS ONE (9)
The prevention of non-indigenous aquatic invasive species spreading into new areas is a goal of many resource managers. New techniques have been developed to survey for species that are difficult to capture with conventional gears that involve the detection of their DNA in water samples (eDNA). This technique is currently...
Maintaining resilience in the face of climate change
Alejandro E. Camacho, T. Douglas Beard Jr.
2014, Book chapter, Social-ecological resilience and law
Climate change, when combined with more conventional stress from human exploitation, calls into question the capacity of both existing ecological communities and resource management institutions to experience disturbances while substantially retaining their same functions and identities (Zellmer and Gunderson 2009; Ruhl 2011). In other words, the physical and biological effects...

Occurrence model for magmatic sulfide-rich nickel-copper-(platinum-group element) deposits related to mafic and ultramafic dike-sill complexes
Klaus J. Schulz, Laurel G. Woodruff, Suzanne W. Nicholson, Robert R. Seal II, Nadine M. Piatak, Val W. Chandler, John L. Mars
2014, Scientific Investigations Report 2010-5070-I
Magmatic sulfide deposits containing nickel (Ni) and copper (Cu), with or without (±) platinum-group elements (PGE), account for approximately 60 percent of the world’s nickel production. Most of the remainder of the Ni production is derived from lateritic deposits, which form by weathering of ultramafic rocks in humid tropical conditions....
Uncertainty analysis of a groundwater flow model in east-central Florida
Nicasio Sepulveda, John E. Doherty
2014, Groundwater
A groundwater flow model for east-central Florida has been developed to help water-resource managers assess the impact of increased groundwater withdrawals from the Floridan aquifer system on heads and spring flows originating from the Upper Floridan aquifer. The model provides a probabilistic description of predictions of interest to water-resource managers,...

2014, Journal of Hydrology (519) 3054-3068
The long-term balance between net precipitation and net groundwater exchange that maintains thousands of seepage lakes in Florida’s karst terrain is explored at a representative lake basin and then regionally for the State’s peninsular lake district. The 15-year water budget of Lake Starr includes El Niño Southern Oscillation (ENSO)-related extremes...
Population viability and connectivity of the Louisiana black bear (Ursus americanus luteolus)
Jared S. Laufenberg, Joseph D. Clark
2014, Open-File Report 2014-1228
In 1992, the U.S. Fish and Wildlife Service (USFWS) granted Ursus americanus luteolus (Louisiana black bear) threatened status under the U.S. Endangered Species Act of 1973, listing loss and fragmentation of habitat as the primary threats. A study was developed by the U.S. Geological Survey in cooperation with the University of Tennessee,...
Radiocarbon dating loess deposits in the Mississippi Valley using terrestrial gastropod shells (Polygyridae, Helicinidae, and Discidae)
Jeffery S. Pigati, John P. McGeehin, Daniel Muhs, David A. Grimley, Jeffrey C. Nekola
2014, Aeolian Research (16) 25-33
Small terrestrial gastropod shells (mainly Succineidae) have been used successfully to date late Quaternary loess deposits in Alaska and the Great Plains. However, Succineidae shells are less common in loess deposits in the Mississippi Valley compared to those of the Polygyridae, Helicinidae, and Discidae families. In this study, we conducted...

John A. Young, Luke R. Iwanowicz, Adam J. Sperry, Vicki Blazer
2014, Environmental Monitoring and Assessment (186) 5531-5545
Endocrine-disrupting compounds (EDCs) are becoming of increasing concern in waterways of the USA and worldwide. What remains poorly understood, however, is how prevalent these emerging contaminants are in the environment and what methods are best able to determine landscape sources of EDCs. We describe the development of a spatially structured...

Surveying the South Pole-Aitken basin magnetic anomaly for remnant impactor metallic iron
Joshua T.S. Cahill, Justin Hagerty, David M. Lawrence, Rachel L. Klima, David T. Blewett
2014, Icarus (243) 27-30
The Moon has areas of magnetized crust ("magnetic anomalies"), the origins of which are poorly constrained. A magnetic anomaly near the northern rim of South Pole-Aitken (SPA) basin was recently postulated to originate from remnant metallic iron emplaced by the SPA basin-forming impactor. Here, we remotely examine the regolith of...
Measurement of unsaturated hydraulic properties and evaluation of property-transfer models for deep sedimentary interbeds, Idaho National Laboratory, Idaho
Kimberlie Perkins, Brittany D. Johnson, Benjamin B. Mirus
2014, Scientific Investigations Report 2014-5206
Operations at the Idaho National Laboratory (INL) have the potential to contaminate the underlying Eastern Snake River Plain (ESRP) aquifer. Methods to quantitatively characterize unsaturated flow and recharge to the ESRP aquifer are needed to inform water-resources management decisions at INL. In particular, hydraulic properties are needed to parameterize distributed...
Assessing inundation hazards to nuclear powerplant sites using geologically extended histories of riverine floods, tsunamis, and storm surges
Jim O’Connor, Brian F. Atwater, Timothy A. Cohn, Thomas M. Cronin, Mackenzie K. Keith, Christopher G. Smith, Mason Jr.
2014, Scientific Investigations Report 2014-5207
Most nuclear powerplants in the United States are near rivers, large lakes, or oceans. As evident from the Fukushima Daiichi, Japan, disaster of 2011, these water bodies pose inundation threats. Geologic records can extend knowledge of rare hazards from flooding, storm surges, and tsunamis. This knowledge can aid in assessing...
