A description of the nearshore fish communities in the Huron-Erie Corridor using multiple gear types
James T. Francis, Justin A. Chiotti, James C. Boase, Mike V. Thomas, Bruce A. Manny, Edward F. Roseman
2013, Journal of Great Lakes Research (40) 52-61
Great Lakes coastal wetlands provide a critical habitat for many fish species throughout their life cycles. Once home to one of the largest wetland complexes in the Great Lakes, coastal wetlands in the Huron–Erie Corridor (HEC) have decreased dramatically since the early 1900s. We characterized the nearshore fish communities at...
Identifying when tagged fishes have been consumed by piscivorous predators: application of multivariate mixture models to movement parameters of telemetered fishes
Jason G. Romine, Russell W. Perry, Samuel V. Johnston, Christopher W. Fitzer, Stephen W. Pagliughi, Aaron R. Blake
2013, Animal Biotelemetry (2)
Background Consumption of telemetered fishes by piscivores is problematic for telemetry studies because tag detections from the piscivore could introduce bias into the analysis of telemetry data. We illustrate the use of multivariate mixture models to estimate group membership (smolt or predator) of telemetered juvenile Chinook salmon...
Native Prairie Adaptive Management: a multi region adaptive approach to invasive plant management on Fish and Wildlife Service owned native prairies
Jill J. Gannon, Terry L. Shaffer, Clinton T. Moore
2013, Open-File Report 2013-1279
Much of the native prairie managed by the U.S. Fish and Wildlife Service (FWS) in the Prairie Pothole Region (PPR) of the northern Great Plains is extensively invaded by the introduced cool-season grasses, smooth brome (Bromus inermis) and Kentucky bluegrass (Poa pratensis). Management to suppress these invasive plants has had...
Bathymetric map, area/capacity table, and sediment volume estimate for Millwood Lake near Ashdown, Arkansas, 2013
Joseph M. Richards, W. Reed Green
2013, Scientific Investigations Map 3282
Millwood Lake, in southwestern Arkansas, was constructed and is operated by the U.S. Army Corps of Engineers (USACE) for flood-risk reduction, water supply, and recreation. The lake was completed in 1966 and it is likely that with time sedimentation has resulted in the reduction of storage capacity of the lake....

Real-time piscicide tracking using Rhodamine WT dye for support of application, transport, and deactivation strategies in riverine environments
Patrick Ryan Jackson, Jonathan D. Lageman
2013, Scientific Investigations Report 2013-5211
Piscicide applications in riverine environments are complicated by the advection and dispersion of the piscicide by the flowing water. Proper deactivation of the fish toxin is required outside of the treatment reach to ensure that there is minimal collateral damage to fisheries downstream or in connecting and adjacent water bodies....

Sharon M. Swanson, Alexander W. Karlsen, Brett J. Valentine
2013, Open-File Report 2013-1257
The Oligocene Frio and Anahuac Formations were assessed as part of the 2007 U.S. Geological Survey (USGS) assessment of Tertiary strata of the U.S. Gulf of Mexico Basin onshore and State waters. The Frio Formation, which consists of sand-rich fluvio-deltaic systems, has been one of the largest hydrocarbon producers from...
Hurricane Isaac: observations and analysis of coastal change
Kristy K. Guy, Hilary F. Stockdon, Nathaniel G. Plant, Kara S. Doran, Karen L.M. Morgan
2013, Open-File Report 2013-1270
Understanding storm-induced coastal change and forecasting these changes require knowledge of the physical processes associated with a storm and the geomorphology of the impacted coastline. The primary physical process of interest is sediment transport that is driven by waves, currents, and storm surge associated with storms. Storm surge, which is...

Correcting length-frequency distributions for imperfect detection
André R. Breton, John A. Hawkins, Dana L. Winkelman
2013, North American Journal of Fisheries Management (33) 1156-1165
Sampling gear selects for specific sizes of fish, which may bias length-frequency distributions that are commonly used to assess population size structure, recruitment patterns, growth, and survival. To properly correct for sampling biases caused by gear and other sources, length-frequency distributions need to be corrected for imperfect detection. We describe...
NGA-West 2 Equations for predicting PGA, PGV, and 5%-Damped PSA for shallow crustal earthquakes
David M. Boore, Jon P. Stewart, Emel Seyhan, Gail M. Atkinson
2013, Earthquake Spectra (30) 1057-1085
We provide ground-motion prediction equations for computing medians and standard deviations of average horizontal component intensity measures (IMs) for shallow crustal earthquakes in active tectonic regions. The equations were derived from a global database with M 3.0–7.9 events. We derived equations for the primary M- and distance-dependence of the IMs...

Peter R. Wright
2013, Scientific Investigations Report 2013-5184
The hydrogeology and water quality of the Snake River alluvial aquifer at the Jackson Hole Airport in northwest Wyoming was studied by the U.S. Geological Survey, in cooperation with the Jackson Hole Airport Board, during water years 2011 and 2012 as part of a followup to a previous baseline study...
Fluvial rainbow trout contribute to the colonization of steelhead (Oncorhynchus mykiss) in a small stream
Dana E. Weigel, Patrick J. Connolly, Madison S. Powell
2013, Environmental Biology of Fishes (97) 1149-1159
Life history polymorphisms provide ecological and genetic diversity important to the long term persistence of species responding to stochastic environments. Oncorhynchus mykiss have complex and overlapping life history strategies that are also sympatric with hatchery populations. Passive integrated transponder (PIT) tags and parentage analysis were used to identify the life...

Next-generation sequencing reveals cryptic mtDNA diversity of Plasmodium relictum in the Hawaiian Islands
S.I. Jarvi, M.E. Farias, D.A. Lapointe, M. Belcaid, C. T. Atkinson
2013, Parasitology (140) 1741-1750
Next-generation 454 sequencing techniques were used to re-examine diversity of mitochondrial cytochrome b lineages of avian malaria (Plasmodium relictum) in Hawaii. We document a minimum of 23 variant lineages of the parasite based on single nucleotide transitional changes, in addition to the previously reported single lineage (GRW4). A new, publicly...
Compilation, quality control, analysis, and summary of discrete suspended-sediment and ancillary data in the United States, 1901-2010
Casey J. Lee, G. Douglas Glysson
2013, Data Series 776
Human-induced and natural changes to the transport of sediment and sediment-associated constituents can degrade aquatic ecosystems and limit human uses of streams and rivers. The lack of a dedicated, easily accessible, quality-controlled database of sediment and ancillary data has made it difficult to identify sediment-related water-quality impairments and has limited...

Michael R. Stevens
2013, Scientific Investigations Report 2012-5267
The U.S. Geological Survey (USGS) began a 5-year study in 2003 that focused on postfire stream-water quality and postfire sediment load in streams within the Hayman and Hinman fire study areas. This report compares water quality of selected streams receiving runoff from unburned areas and burned areas using concentrations and...
Mountain pine beetle impacts on vegetation and carbon stocks
Todd Hawbaker, Jennifer S. Briggs, Megan K. Caldwell, Susan Stitt
2013, Fact Sheet 2013-3095
In the Southern Rocky Mountains, an epidemic outbreak of mountain pine beetle (Dendroctonus ponderosae; MPB) has caused levels of tree mortality unprecedented in recorded history. The impacts of this mortality on vegetation composition, forest structure, and carbon stocks have only recently received attention, although the impacts of other disturbances such...
