Jeff S. Hatfield, Floyd W. Weckerly, Adam Duarte
2012, Wildlife Society Bulletin (36) 415-422
Using the golden-cheeked warbler (Setophaga chrysoparia) as a case study, this paper discusses what lessons can be learned from the process of the emergency listing and subsequent development of the recovery plan. Are the metrics for recovery in the current warbler plan appropriate, including population size and distribution (recovery units),...

Ann L. Allert, Robert J. DiStefano, Christopher J. Schmitt, James F. Fairchild, William G. Brumbaugh
2012, Archives of Environmental Contamination and Toxicology (63) 563-573
Riffle-dwelling crayfish populations were sampled at 16 sites in 4 tributaries of the Spring River located within the Tri-State Mining District in southwest Missouri. Crayfish density, physical habitat quality, and water quality were examined at each site to assess the ecological effects of mining-derived metals on crayfish. Metals (lead, zinc,...
Tracking climate impacts on the migratory monarch butterfly
Elise F. Zipkin, Leslie Ries, Rick Reeves, James Regetz, Karen S. Oberhauser
2012, Global Change Biology (18) 3039-3049
Understanding the impacts of climate on migratory species is complicated by the fact that these species travel through several climates that may be changing in diverse ways throughout their complete migratory cycle. Most studies are not designed to tease out the direct and indirect effects of climate at various stages...

David A. Eads, Dean E. Biggins, Dustin Marsh, Joshua J. Millspaugh, Travis M. Livieri
2012, Western North American Naturalist (72) 140-147
Black-footed ferrets (Mustela nigripes) excavate soil from prairie dog (Cynomys spp.) burrows, thereby creating characteristic soil deposits at burrow openings. These soil deposits have been observed only rarely in summer. We monitored adult ferrets during June–October of the years 2007 and 2008 on a 452-ha colony of black-tailed prairie dogs...

An experimental evaluation of potential scavenger effects on snake road mortality detections
Kaylan A. Hubbard, Anna D. Chalfoun
2012, Herpetological Conservation and Biology (7) 150-156
As road networks expand and collisions between vehicles and wildlife become more common, accurately quantifying mortality rates for the taxa that are most impacted will be critical. Snakes are especially vulnerable to collisions with vehicles because of their physiology and behavior. Reptile road mortality is typically quantified using driving or...

Arthropod prey for riparian associated birds in headwater forests of the Oregon Coast Range
Joan C. Hagar, Judith Li, Janel Sobota, Stephanie Jenkins
2012, Forest Ecology and Management (285) 213-226
Headwater riparian areas occupy a large proportion of the land base in Pacific Northwest forests, and thus are ecologically and economically important. Although a primary goal of management along small headwater streams is the protection of aquatic resources, streamside habitat also is important for many terrestrial wildlife species. However, mechanisms...

Streamflow record extension for selected streams in the Susitna River Basin, Alaska
Janet H. Curran
2012, Scientific Investigations Report 2012-5210
Daily streamflow records for water years 1950–2010 in the Susitna River Basin range in length from 4 to 57 years, and many are distributed within that period in a way that might not adequately represent long-term streamflow conditions. Streamflow in the basin is affected by the Pacific Decadal Oscillation (PDO),...

Disputes over science and dispute resolution approaches - A survey of Bureau of Reclamation employees
Nina Burkardt, Emily W. Ruell
2012, Open-File Report 2012-1186
Water resources in parts of the Western United States are over-allocated, which intensifies the pressure to support water management decisions with strong scientific evidence. Because scientific studies sometimes provide uncertain or competing results or recommendations, science can become a source of disputes during decision-making processes. The Bureau of Reclamation (Reclamation)...
Lahar hazard zones for eruption-generated lahars in the Lassen Volcanic Center, California
Joel E. Robinson, Michael A. Clynne
2012, Scientific Investigations Report 2012-5176-C
Lahar deposits are found in drainages that head on or near Lassen Peak in northern California, demonstrating that these valleys are susceptible to future lahars. In general, lahars are uncommon in the Lassen region. Lassen Peak's lack of large perennial snowfields and glaciers limits its potential for lahar development, with...
