2011, Open-File Report 2011-1276
Based on a National Park Service (NPS) landcover classification, a landcover map of the 715-km (444-mile) NPS Natchez Trace Parkway (hereafter referred to as the "Parkway") was created. The NPS landcover classification followed National Vegetation Classification (NVC) protocols. The landcover map, which extended the initial landcover classification to the entire...

Dan J. Tomaszewski
2011, Scientific Investigations Map 3173
The Chicot equivalent aquifer system is an important source of freshwater in southeastern Louisiana. In 2005, about 47 million gallons per day (Mgal/d) were withdrawn from the Chicot equivalent aquifer system in East Baton Rouge, East Feliciana, Livingston, Tangipahoa, St. Helena, St. Tammany, Washington, and West Feliciana Parishes. Concentrated withdrawals...

Loren L. Wehmeyer, Brian D. Reece
2011, Fact Sheet 2011-3152
The 2008–11 data rescue and recovery efforts by the U.S. Geological Survey (USGS) Texas Water Science Center resulted in an efficient workflow process, database, and Web user interface for scientists and citizens to access archived environmental information with practical applications. Much of this information is unique and has never been...
Survival, growth and reproduction of non-indigenous Nile tilapia, Oreochromis niloticus (Linnaeus 1758). I. Physiological capabilities in various temperatures and salinities
Pamela J. Schofield, Mark S. Peterson, Michael R. Lowe, Nancy J. Brown-Peterson, William T. Slack
2011, Marine and Freshwater Research (62) 439-449
The physiological tolerances of non-native fishes is an integral component of assessing potential invasive risk. Salinity and temperature are environmental variables that limit the spread of many non-native fishes. We hypothesised that combinations of temperature and salinity will interact to affect survival, growth, and reproduction of Nile tilapia, Oreochromis niloticus,...
Structural controls and evolution of gold-, silver-, and REE-bearing copper-cobalt ore deposits, Blackbird district, east-central Idaho: Epigenetic origins
K. Lund, Russell G. Tysdal, Karl V. Evans, Michael J. Kunk, Renee M. Pillers
2011, Economic Geology (106) 585-618
The Cu-Co ± Au (± Ag ± Ni ± REE) ore deposits of the Blackbird district, east-central Idaho, have previously been classified as Besshi-type VMS, sedex, and IOCG deposits within an intact stratigraphic section. New studies indicate that, across the district, mineralization was introduced into the country rocks as a...
Structural complexity, movement bias, and metapopulation extinction risk in dendritic ecological networks
Evan H. Campbell Grant
2011, Journal of the North American Benthological Society (30) 252-258
Spatial complexity in metacommunities can be separated into 3 main components: size (i.e., number of habitat patches), spatial arrangement of habitat patches (network topology), and diversity of habitat patch types. Much attention has been paid to lattice-type networks, such as patch-based metapopulations, but interest in understanding ecological networks of alternative...
Survival and growth of newly transformed Lampsilis cardium and Lampsilis siliquoidea in a flow-through, continuous feeding test system
Jeffery R. Meinertz, Theresa M. Schreier, Karina R. Hess, Michelle Bartsch
2011, American Malacological Bulletin (29) 69-75
A test system was evaluated for assessing chronic toxicity of waterborne chemicals with early life stage mussels. To determine if the test system could result in ≥80% survival in a control (unexposed) group, fat mucket mussels (Lampsilis siliquoidea Barnes, 1823) and plain pocketbook mussels (L. cardium Rafinesque, 1820) 1 day...
Stage structure alters how complexity affects stability of ecological networks
V. H. W. Rudolf, Kevin D. Lafferty
2011, Ecology Letters (14) 75-79
Resolving how complexity affects stability of natural communities is of key importance for predicting the consequences of biodiversity loss. Central to previous stability analysis has been the assumption that the resources of a consumer are substitutable. However, during their development, most species change diets; for instance, adults often use different...
Sperm quality assessments for endangered razorback suckers Xyrauchen texanus
Jill A. Jenkins, Bruce E. Eilts, Amy M. Guitreau, Chester R. Figiel, Rassa O. Draugelis-Dale, Terrence R. Tiersch
2011, Reproduction (141) 55-65
Flow cytometry (FCM) and computer-assisted sperm motion analysis (CASA) methods were developed and validated for use with endangered razorback suckers Xyrauchen texanus collected (n=64) during the 2006 spawning season. Sperm motility could be activated within osmolality ranges noted during milt collections (here 167–343 mOsm/kg). We hypothesized that sperm quality of...
Forest species diversity reduces disease risk in a generalist plant pathogen invasion
Sarah E. Haas, Mevin Hooten, David M. Rizzo, Ross K. Meentemeyer
2011, Ecology Letters (14) 1108-1116
Empirical evidence suggests that biodiversity loss can increase disease transmission, yet our understanding of the 'diversity-disease hypothesis' for generalist pathogens in natural ecosystems is limited. We used a landscape epidemiological approach to examine two scenarios regarding diversity effects on the emerging plant pathogen Phytophthora ramorum across a broad, heterogeneous ecoregion:...

We review global efforts to minimize the risk and limit the impact of invasions in this widely used plant group.Location Global.Methods Using information from literature sources, knowledge and experience...
Was pre–twentieth century sea level stable?
Thomas M. Cronin
2011, Eos, Transactions, American Geophysical Union (92) 455-456
Sea level rise (SLR) ranks high on the list of climate change issues because the expected acceleration from the current rate (about 3.1 millimeters per year) poses threats to coastal regions. Tide gauge, salt marsh, and archaeological records, and modeling of glacioisostatic adjustment (GIA) have led to the widely accepted...

R.L. Huffman, R.S. Dinicola
2011, Data Series 644
Previous investigations indicate that natural attenuation and biodegradation of chlorinated volatile organic compounds (VOCs) are substantial in groundwater beneath the 9-acre former landfill at Operable Unit 1 (OU 1), Naval Undersea Warfare Center, Division Keyport, Washington. Phytoremediation combined with ongoing natural attenuation processes was the preferred remedy selected by the...

Source-water susceptibility assessment in Texas—Approach and methodology
Randy L. Ulery, John E. Meyer, Robert W. Andren, Jeremy K. Newson
2011, Scientific Investigations Report 2011-5197
Public water systems provide potable water for the public's use. The Safe Drinking Water Act amendments of 1996 required States to prepare a source-water susceptibility assessment (SWSA) for each public water system (PWS). States were required to determine the source of water for each PWS, the origin of any...
