Effects of recruitment, growth, and exploitation on walleye population size structure in northern Wisconsin lakes
Michael J. Hansen, Nancy A. Nate
2014, Journal of Fish and Wildlife Management (5) 99-108
We evaluated the dynamics of walleye Sander vitreus population size structure, as indexed by the proportional size distribution (PSD) of quality-length fish, in Escanaba Lake during 1967–2003 and in 204 other lakes in northern Wisconsin during 1990–2011. We estimated PSD from angler-caught walleyes in Escanaba Lake and from spring electrofishing...

This chapter provides an overview of geochemical modeling that applies to water–rock interactions under ambient conditions of temperature and pressure. Topics include modeling definitions, historical background, issues of activity coefficients, popular codes and databases, examples of modeling common types of water–rock interactions, and issues of model reliability. Examples include speciation,...
A mapping and monitoring assessment of the Philippines' mangrove forests from 1990 to 2010
Jordan Long, Darrell Napton, Chandra Giri, Jordan Graesser
2014, Journal of Coastal Research (30) 260-271
Information on the present condition and spatiotemporal dynamics of mangrove forests is needed for land-change studies and integrated natural resources planning and management. Although several national mangrove estimates for the Philippines exist, information is unavailable at sufficient spatial and thematic detail for change analysis. Historical and contemporary mangrove distribution maps...
Streamflow, water quality, and aquatic macroinvertebrates of selected streams in Fairfax County, Virginia, 2007-12
John D. Jastram
2014, Scientific Investigations Report 2014-5073
Efforts to mitigate the effects of urbanization on streams rely on best management practices (BMPs) that are implemented with the intent of reducing and retaining stormwater runoff. A cooperative monitoring effort between the U.S. Geological Survey and Fairfax County, Virginia, was initiated in 2007 to assess the condition of county...

Nicholas J. Porter, Timothy F. Bonvechio, Joshua L. McCormick, Michael Quist
2014, Journal of the Southeastern Association of Fish and Wildlife Agencies 103-109
The objectives of this study were to evaluate the population dynamics of bowfin (Amia calva) in Lake Lindsay Grace, Georgia, and to compare those dynamics to other bowfin populations. Relative abundance of bowfin sampled in 2010 in Lake Lindsay Grace was low and variable (mean±SD; 2.7±4.7 fish per hour of...

Noah S. Adams, John M. Plumb, Russell W. Perry, Dennis W. Rondorf
2014, North American Journal of Fisheries Management (34) 576-594
An integral part of efforts to recover stocks of Pacific salmon Oncorhynchus spp. and steelhead O. mykiss in Pacific Northwest rivers is to increase passage efficacy and survival of juveniles past hydroelectric dams. As part of this effort, we evaluated the efficacy of a prototype surface bypass structure, the removable spillway weir (RSW), installed...
The response of stream periphyton to Pacific salmon: using a model to understand the role of environmental context
J. Ryan Bellmore, Alexander K. Fremier, Francine Mejia, Michael Newsom
2014, Freshwater Biology (59) 1437-1451
1. In stream ecosystems, Pacific salmon deliver subsidies of marine-derived nutrients and disturb the stream bed during spawning. The net effect of this nutrient subsidy and physical disturbance on biological communities can be hard to predict and is likely to be mediated by environmental conditions. For periphyton, empirical studies have...
Mapping mountain pine beetle mortality through growth trend analysis of time-series landsat data
Lu Liang, Yanlei Chen, Todd Hawbaker, Zhi-Liang Zhu, Peng Gong
2014, Remote Sensing (6) 5696-5716
Disturbances are key processes in the carbon cycle of forests and other ecosystems. In recent decades, mountain pine beetle (MPB; Dendroctonus ponderosae) outbreaks have become more frequent and extensive in western North America. Remote sensing has the ability to fill the data gaps of long-term infestation monitoring, but the elimination...

Andrew M. O’Reilly, Edwin A. Roehl Jr., Paul Conrads, Ruby C. Daamen, Matthew D. Petkewich
2014, Scientific Investigations Report 2014-5032
The urbanization of central Florida has progressed substantially in recent decades, and the total population in Lake, Orange, Osceola, Polk, and Seminole Counties more than quadrupled from 1960 to 2010. The Floridan aquifer system is the primary source of water for potable, industrial, and agricultural purposes in central Florida. Despite...
PAH concentrations in lake sediment decline following ban on coal-tar-based pavement sealants in Austin, Texas
Peter C. Van Metre, Barbara Mahler
2014, Environmental Science & Technology (48) 7222-7228
Recent studies have concluded that coal-tar-based pavement sealants are a major source of polycyclic aromatic hydrocarbons (PAHs) in urban settings in large parts of the United States. In 2006, Austin, TX, became the first jurisdiction in the U.S. to ban the use of coal-tar sealants. We evaluated the effect of...

Histograms showing variations in oil yield, water yield, and specific gravity of oil from Fischer assay analyses of oil-shale drill cores and cuttings from the Piceance Basin, northwestern Colorado
John D. Dietrich, Michael E. Brownfield, Ronald C. Johnson, Tracey J. Mercier
2014, Open-File Report 2014-1057
Recent studies indicate that the Piceance Basin in northwestern Colorado contains over 1.5 trillion barrels of oil in place, making the basin the largest known oil-shale deposit in the world. Previously published histograms display oil-yield variations with depth and widely correlate rich and lean oil-shale beds and zones throughout the...
Variability common to global sea surface temperatures and runoff in the conterminous United States
Gregory J. McCabe, David M. Wolock
2014, Journal of Hydrometeorology (15) 714-725
Singular value decomposition (SVD) is used to identify the variability common to global sea surface temperatures (SSTs) and water-balance-modeled water-year (WY) runoff in the conterminous United States (CONUS) for the 1900–2012 period. Two modes were identified from the SVD analysis; the two modes explain 25% of the variability in WY...

David P. Schwartz, James J. Lienkaemper, Suzanne Hecker, Keith I. Kelson, Thomas E. Fumal, John N. Baldwin, Gordon G. Seitz, Tina Niemi
2014, Bulletin of the Seismological Society of America
Stress changes produced by the 1906 San Francisco earthquake had a profound effect on the seismicity of the San Francisco Bay region (SFBR), dramatically reducing it in the twentieth century. Whether the SFBR is still within or has emerged from this seismic quiescence is an issue of debate with implications...

Gregory J. McCabe, David M. Wolock
2014, Geophysical Research Letters (41) 6889-6897
Spatial and temporal patterns in annual and seasonal minimum, mean, and maximum daily streamflow values were examined for a set of 516 reference stream gauges located throughout the conterminous United States for the period 1951–2009. Cluster analysis was used to classify the stream gauges into 14 groups based on similarity...

Reproductive ecology of lampreys
Nicholas S. Johnson, Tyler J. Buchinger, Weiming Li
2014, Book chapter, Lampreys: Biology, Conservation and Control
Lampreys typically spawn in riffle habitats during the spring. Spawning activity and diel (i.e., during daylight and at night) behavioral patterns are initiated when spring water temperatures increase to levels that coincide with optimal embryologic development. Nests are constructed in gravel substrate using the oral disc to move stones and...

2014, Data Series 796
The California Groundwater Units dataset classifies and delineates areas within the State of California into one of three groundwater-based polygon units: (1) those areas previously defined as alluvial groundwater basins or subbasins, (2) highland areas that are adjacent to and topographically upgradient of groundwater basins, and (3) highland areas not...
