Leslie Richardson, John B. Loomis, Patricia A. Champ
2013, Land Economics (89) 76-100
Estimating the economic benefits of reduced health damages due to improvements in environmental quality continues to challenge economists. We review welfare measures associated with reduced wildfire smoke exposure, and a unique dataset from California’s Station Fire of 2009 allows for a comparison of cost of illness (COI) estimates with willingness...
Monitoring the status of forests and rangelands in the Western United States using ecosystem performance anomalies
Matthew B. Rigge, Bruce Wylie, Yingxin Gu, Jayne Belnap, Khem P. Phuyal, Larry Tieszen
2013, International Journal of Remote Sensing (34) 4049-4068
The effects of land management and disturbance on ecosystem performance (i.e. biomass production) are often confounded by those of weather and site potential. The current study overcomes this issue by calculating the difference between actual and expected ecosystem performance (EEP) to generate ecosystem performance anomalies (EPA). This study aims to...
Limitation and facilitation of one of the world's most invasive fish: an intercontinental comparison
Phaedra E. Budy, Gary P. Thiede, Javier Lobon-Cervia, Gustavo Gonzolez Fernandez, Peter McHugh, Angus McIntosh, Lief Asbjorn Vollestad, Eloy Becares, Phillip Jellyman
2013, Ecology (94) 356-367
Purposeful species introductions offer opportunities to inform our understanding of both invasion success and conservation hurdles. We evaluated factors determining the energetic limitations of brown trout (Salmo trutta) in both their native and introduced ranges. Our focus was on brown trout because they are nearly globally distributed, considered one of...
Use of classification trees to apportion single echo detections to species: Application to the pelagic fish community of Lake Superior
Daniel L. Yule, Jean V. Adams, Thomas R. Hrabik, Mark R. Vinson, Zebadiah Woiak, Tyler D. Ahrenstroff
2013, Fisheries Research (140) 123-132
Acoustic methods are used to estimate the density of pelagic fish in large lakes with results of midwater trawling used to assign species composition. Apportionment in lakes having mixed species can be challenging because only a small fraction of the water sampled acoustically is sampled with trawl gear. Here we...
Rapid increases and time-lagged declines in amphibian occupancy after wildfire
Blake R. Hossack, Winsor H. Lowe, Paul Stephen Corn
2013, Conservation Biology (27) 219-228
Climate change is expected to increase the frequency and severity of drought and wildfire. Aquatic and moisture-sensitive species, such as amphibians, may be particularly vulnerable to these modified disturbance regimes because large wildfires often occur during extended droughts and thus may compound environmental threats. However, understanding of the effects of...
Late quaternary slip-rate variations along the Warm Springs Valley fault system, northern Walker Lane, California-Nevada border
Ryan Gold, Craig dePolo, Richard W. Briggs, Anthony Crone, John Goss
2013, Bulletin of the Seismological Society of America (103) 542-558
The extent to which faults exhibit temporally varying slip rates has important consequences for models of fault mechanics and probabilistic seismic hazard. Here, we explore the temporal behavior of the dextral‐slip Warm Springs Valley fault system, which is part of a network of closely spaced (10–20 km) faults in the...

Birgit E. Peterson, Kurtis Nelson, Bruce Wylie
2013, Photogrammetric Engineering and Remote Sensing (79) 175-183
Comprehensive canopy structure and fuel data are critical for understanding and modeling wildland fire. The LANDFIRE project produces such data nationwide based on a collection of field observations, Landsat imagery, and other geospatial data. Where field data are not available, alternate strategies are being investigated. In this study, vegetation structure...

Miguel L. Villarreal, Laura M. Norman, Cynthia S.A. Wallace, Kenneth G. Boykin
2013, International Journal of Biodiversity Science, Ecosystem Services and Management (9) 90-103
The Sonoran Desert and Apache Highlands ecoregions of North America are areas of exceptionally high plant and vertebrate biodiversity. However, much of the vertebrate biodiversity is supported by only a few vegetation types with limited distributions, some of which are increasingly threatened by changing land uses. We assessed the impacts...

Lake Ballinger has been affected by input of metal contaminants emitted from the Tacoma smelter, which operated from 1887 to 1986 and was located about 53 km south...
Rupture history of the 2008 Mw 7.9 Wenchuan, China, earthquake: Evaluation of separate and joint inversions of geodetic, teleseismic, and strong-motion data
Stephen H. Hartzell, Carlos Mendoza, Leonardo Ramírez-Guzmán, Yuesha Zeng, Walter Mooney
2013, Bulletin of the Seismological Society of America (103) 353-370
An extensive data set of teleseismic and strong-motion waveforms and geodetic offsets is used to study the rupture history of the 2008 Wenchuan, China, earthquake. A linear multiple-time-window approach is used to parameterize the rupture. Because of the complexity of the Wenchuan faulting, three separate planes are used to represent...

Christina Riesselman, R. B. Dunbar
2013, Palaeogeography, Palaeoclimatology, Palaeoecology (369) 136-153
The late Pliocene, ~ 3.3–3.0 Ma, is the most recent interval of sustained global warmth in the geologic past. This window is the focus of climate reconstruction efforts by the U.S. Geological Survey's Pliocene Research, Interpretation, and Synoptic Mapping (PRISM) Data/Model Cooperative, and may provide a useful climate analog for the coming...

A regional classification of the effectiveness of depressional wetlands at mitigating nitrogen transport to surface waters in the Northern Atlantic Coastal Plain
Scott W. Ator, Judith M. Denver, Andrew E. LaMotte, Andrew J. Sekellick
2013, Scientific Investigations Report 2012-5266
Nitrogen from nonpoint sources contributes to eutrophication, hypoxia, and related ecological degradation in Atlantic Coastal Plain streams and adjacent coastal estuaries such as Chesapeake Bay and Pamlico Sound. Although denitrification in depressional (non-riparian) wetlands common to the Coastal Plain can be a significant landscape sink for nitrogen, the effectiveness of...
