David A. Hewitt, Eric C. Janney, Brian S. Hayes, Alta C. Harris
2014, Open-File Report 2014-1186
Data from a long-term capture-recapture program were used to assess the status and dynamics of populations of two long-lived, federally endangered catostomids in Upper Klamath Lake, Oregon. Lost River suckers (Deltistes luxatus) and shortnose suckers (Chasmistes brevirostris) have been captured and tagged with passive integrated transponder (PIT) tags during their...

2014, Open-File Report 2014-1160
Multibeam-echosounder data, collected during survey H12299 by the National Oceanic and Atmospheric Administration in a 162-square-kilometer area of Block Island Sound, northeast of Gardiners Island, New York, are used along with sediment samples and bottom photography, collected at 37 stations in this area by the U.S. Geological Survey during cruise...
Incorporating cold-air pooling into downscaled climate models increases potential refugia for snow-dependent species within the Sierra Nevada Ecoregion, CA
Jennifer A. Curtis, Lorraine E. Flint, Alan L. Flint, Jessica D. Lundquist, Brian Hudgens, Erin E. Boydston, Julie K. Young
2014, PLoS ONE (9) 1-13
We present a unique water-balance approach for modeling snowpack under historic, current and future climates throughout the Sierra Nevada Ecoregion. Our methodology uses a finer scale (270 m) than previous regional studies and incorporates cold-air pooling, an atmospheric process that sustains cooler temperatures in topographic depressions thereby mitigating snowmelt. Our...
Physiological condition of juvenile wading birds in relation to multiple landscape stressors in the Florida Everglades: effects of hydrology, prey availability, and mercury bioaccumulation
Garth Herring, Collin A. Eagles-Smith, Dale E. Gawlik, James M. Beerens, Joshua T. Ackerman
2014, PLoS ONE (9)
The physiological condition of juvenile birds can be influenced by multiple ecological stressors, and few studies have concurrently considered the effects of environmental contaminants in combination with ecological attributes that can influence foraging conditions and prey availability. Using three temporally distinct indices of physiological condition, we compared the physiological response...

Tim R. Orr
2014, Scientific Investigations Report 2014-5124
Episode 57 of Kīlauea’s long-lived east rift zone eruption was characterized by lava effusion and spattering within the crater at Puʻu ʻŌʻō that lasted from July 1 to July 20, 2007. This eruptive episode represented a resumption of activity following a 12-day eruptive hiatus on Kīlauea associated with the episode...
Do cities simulate climate change? A comparison of herbivore response to urban and global warming
Elsa Youngsteadt, Adam G. Dale, Adam Terando, Robert R. Dunn, Steven D. Frank
2014, Global Change Biology (21) 97-105
Cities experience elevated temperature, CO2, and nitrogen deposition decades ahead of the global average, such that biological response to urbanization may predict response to future climate change. This hypothesis remains untested due to a lack of complementary urban and long-term observations. Here, we examine the response of an herbivore, the...

Thomas M. Brocher, Robert A. Page, Peter H. Stauffer, James W. Hendley II
2014, Fact Sheet 2014-3092
The 1989 Loma Prieta earthquake interrupted several decades of seismic tranquility in the San Francisco Bay Area. It caused damage throughout the region and was a wakeup call to prepare for potentially even more damaging future quakes. Since 1989, the work of the U.S. Geological Survey and many other organizations...
Operational earthquake forecasting can enhance earthquake preparedness
T.H. Jordan, W. Marzocchi, A.J. Michael, M.C. Gerstenberger
2014, Seismological Research Letters (85) 955-959
We cannot yet predict large earthquakes in the short term with much reliability and skill, but the strong clustering exhibited in seismic sequences tells us that earthquake probabilities are not constant in time; they generally rise and fall over periods of days to years in correlation with nearby seismic activity....

Jeffrey R. Barbaro, John P. Masterson, Denis R. LeBlanc
2014, Fact Sheet 2014-3067
Groundwater is the sole source of drinking water and a major source of freshwater for domestic, industrial, and agricultural uses on Cape Cod, Massachusetts. Groundwater discharged from aquifers also supports freshwater pond and stream ecosystems and coastal wetlands. Six hydraulically distinct groundwater-flow systems (lenses) have been delineated on Cape Cod....

Early detection of invasive plants: principles and practices
Bradley A. Welch, Paul H. Geissler, Penelope Latham
2014, Scientific Investigations Report 2012-5162
Invasive plants infest an estimated 2.6 million acres of the 83 million acres managed by the National Park Service (NPS) in the United States. The consequences of these invasions present a significant challenge for the NPS to manage the agency’s natural resources “unimpaired for the enjoyment of future generations.” More...

Patterns of lake occupancy by fish indicate different adaptations to life in a harsh Arctic environment
Trevor B. Haynes, Amanda E. Rosenberger, Mark S. Lindberg, Matthew Whitman, Joel A. Schmutz
2014, Freshwater Biology (59) 1884-1896
Summary For six fish species sampled from 86 lakes on the Arctic Coastal Plain, Alaska, we examined whether lake occupancy was related to variables representing lake size, colonisation potential and/or the presence of overwintering habitat. We found the relative importance of each factor for a given species could be related to its...
Using posts to an online social network to assess fishing effort
Dustin R. Martin, Christopher J. Chizinski, Kent M. Eskridge, Kevin L Pope
2014, Fisheries Research (157) 24-27
Fisheries management has evolved from reservoir to watershed management, creating a need to simultaneously gather information within and across interacting reservoirs. However, costs to gather information on the fishing effort on multiple reservoirs using traditional creel methodology are often prohibitive. Angler posts about reservoirs online provide a unique medium to...
Use of oviduct-inserted acoustic transmitters and positional telemetry to estimate timing and location of spawning: a feasibility study in lake trout, Salvelinus namaycush
Thomas R. Binder, Christopher M. Holbrook, Scott M. Miehls, Henry T. Thompson, Charles C. Krueger
2014, Animal Biotelemetry (2)
Background Oviduct-inserted transmitters have shown promise for determining precise location of spawning in fishes. Use of traditional manual tracking to locate expelled oviduct transmitters is laborious and accurate estimates of time of transmitter expulsion require frequent surveys. We tested the feasibility of using oviduct-inserted transmitters with positional telemetry to estimate time...

Giovanni De Giudici, Richard B. Wanty, F. Podda, Briant A. Kimball, Philip L. Verplanck, P. Lattanzi, R. Cidu, D. Medas
2014, Chemical Geology (384) 110-119
Streams draining mined areas throughout the world commonly have high concentrations of Zn. Because Zn is not easily removed from stream water and because it can be toxic to aquatic organisms, its presence is a persistent problem. The discovery of biomineralization of Zn-bearing solids in the mine drainage of Rio...
