Gypsies in the palace: Experimentalist's view on the use of 3-D physics-based simulation of hillslope hydrological response
A.L. James, Jeffery J. McDonnell, I. Tromp-Van Meerveld, N.E. Peters
2010, Hydrological Processes (24) 3878-3893
As a fundamental unit of the landscape, hillslopes are studied for their retention and release of water and nutrients across a wide range of ecosystems. The understanding of these near-surface processes is relevant to issues of runoff generation, groundwater-surface water interactions, catchment export of nutrients, dissolved organic carbon, contaminants (e.g....
Juvenile Salmonid survival, passage, and egress at McNary Dam during tests of temporary spillway weirs, 2009
N.S. Adams, T.L. Liedtke
2010, Report
We evaluated behavior, passage, and survival of juvenile salmonids at McNary Dam in relation to the temporary spillway weirs (TSWs) using acoustic telemetry during 2009. The TSWs were located in spill bays 4 and 20 during spring and in spill bays 19 and 20 during summer. Our objectives were to...

Kinetics of selenium release in mine waste from the Meade Peak Phosphatic Shale, Phosphoria Formation, Wooley Valley, Idaho, USA
Lisa L. Stillings, Michael C. Amacher
2010, Chemical Geology (269) 113-123
Phosphorite from the Meade Peak Phosphatic Shale member of the Permian Phosphoria Formation has been mined in southeastern Idaho since 1906. Dumps of waste rock from mining operations contain high concentrations of Se which readily leach into nearby streams and wetlands. While the most common mineralogical residence of Se...
Effectiveness of post-fire seeding in desert tortoise Critical Habitat following the 2005 Southern Nevada Fire Complex
Lesley DeFalco, K. Kristina Drake, S. J. Scoles-Sciulla, Kyla L. Bauer
2010, Report
In June 2005, lightning strikes ignited multiple wildfires in southern Nevada. The Southern Nevada Fire Complex burned more than 32,000 acres of designated desert tortoise Critical Habitat and an additional 403,000 acres of Mojave Desert habitat characterized as potentially suitable for the tortoise. Mortalities of desert tortoises were observed after...
Nearshore concentration of pink shrimp (Farfantepenaeus duorarum) postlarvae in northern Florida bay in relation to nocturnal flood tide
Maria M. Criales, M. B. Robblee, Joan A. Browder, H. Cardenas, Thomas L. Jackson
2010, Bulletin of Marine Science (86) 53-74
We address the question of whether the low abundance of juvenile pink shrimp Farfantepenaeus duorarum (Burkenroad, 1939) in northern-central Florida Bay results from (i) limiting environmental conditions, (ii) a reduced postlarval transport, or (iii) both. To explore this question, postlarvae were collected during the new moon in both summer and...
A likelihood framework for joint estimation of salmon abundance and migratory timing using telemetric mark-recapture
Jeffrey F. Bromaghin, Kenneth S. Gates, Douglas E. Palmer
2010, North American Journal of Fisheries Management (30) 1385-1394
Many fisheries for Pacific salmon Oncorhynchus spp. are actively managed to meet escapement goal objectives. In fisheries where the demand for surplus production is high, an extensive assessment program is needed to achieve the opposing objectives of allowing adequate escapement and fully exploiting the available surplus. Knowledge of abundance is a critical...
Post-construction monitoring of a Core-Loc™ breakwater using tripod-based LiDAR
Jessica H. Podoski, Gerald W. Bawden, Sandra Bond, Thomas D. Smith, James Foster
2010, Book chapter, Coasts, marine structures and breakwaters: Adapting to change
The goal of the technology application described herein is to determine whether breakwater monitoring data collected using Tripod (or Terrestrial) Light Detection and Ranging (T-LiDAR) can give insight into processes such as how Core-Loc™ concrete armour units nest following construction, and in turn how settlement affects armour layer stability, concrete...
Unbiased survival estimates and evidence for skipped breeding opportunities in females
Erin L. Muths, Rick D. Scherer, Brad A. Lambert
2010, Methods in Ecology and Evolution (1) 123-130
1. Estimates of demographic parameters for females, in many organisms, are sparse. This is particularly worrisome as more and more species are faced with high extinction probabilities and conservation increasingly depends on actions dictated by complex predictive models that require accurate estimates of demographic parameters for each sex and species. 2. This study...

J.W. Cain III, R.S. Felger, B.D. Jansen, P.R. Krausman
2010, Journal of the Botanical Research Institute of Texas (4) 755-760
During the course of field work in Cabeza Prieta National Wildlife Refuge, southwestern Arizona, in 2003, James Cain and Brian Jansen collected Salvia vaseyi, previously known only from the western edge of the Sonoran Desert in California and Baja California. Our findings indicate this shrub might be more widespread in...

Passage and behavior of radio-tagged adult Pacific lampreys (Entosphenus tridentatus) at the Willamette Falls Project, Oregon.
Matthew G. Mesa, Robert J. Magie, Elizabeth S. Copeland
2010, Northwest Science (84) 233-242
Populations of Pacific lamprey (Entosphenus tridentatus) in the Columbia River basin have declined and passage problems at dams are a contributing factor. We used radio telemetry to monitor the passage of adult Pacific lampreys at the Willamette Falls Project (a hydroelectric dam integrated into a natural falls) on the Willamette...

Matthew G. Mesa, Jennifer M. Bayer, Mara B. Bryan, Stacia A. Sower
2010, Comparative Biochemistry and Physiology, Part A: Molecular & Integrative Physiology (155) 56-63
We documented changes in plasma levels of estradiol 17-β (E2), progesterone (P), 15α-hydroxytestosterone (15α-T), thyroxine (T4), triiodothyronine (T3), protein, triglycerides (TGs), and glucose in adult Pacific lampreys (Entosphenus tridentatus) held in the laboratory in two different years. Levels of E2 in both sexes ranged from 0.5 to 2 ng/mL from September...

Intercontinental reassortment and genomic variation of low pathogenic avian influenza viruses isolated from northern pintails (Anas acuta) in Alaska: examining the evidence through space and time
Andrew M. Ramey, John M. Pearce, Paul L. Flint, S. Ip, Dirk V. Derksen, J. Christian Franson, Michael J. Petrula, Bradley D. Scotton, Kristine M. Sowl, Michael L. Wege, Kimberly A. Trust
2010, Virology (401) 179-189
Migration and population genetic data for northern pintails (Anas acuta) and phylogenetic analysis of low pathogenic avian influenza (LPAI) viruses from this host in Alaska suggest that northern pintails are involved in ongoing intercontinental transmission of avian influenza. Here, we further refine this conclusion through phylogenetic analyses which demonstrate that...

Multiple well-shutdown tests and site-scale flow simulation in fractured rocks
Claire R. Tiedeman, Pierre J. Lacombe, Daniel J. Goode
2010, Groundwater (48) 401-415
A new method was developed for conducting aquifer tests in fractured-rock flow systems that have a pump-and-treat (P&T) operation for containing and removing groundwater contaminants. The method involves temporary shutdown of individual pumps in wells of the P&T system. Conducting aquifer tests in this manner has several advantages, including (1)...
Anthropogenic influence on recent bathymetric change in west-central San Francisco Bay
Patrick L. Barnard, Rikk G. Kvitek
2010, San Francisco Estuary and Watershed Science (8)
Two multibeam sonar surveys of west-central San Francisco Bay, California, were conducted in 1997 and 2008. Bathymetric change analysis between the two surveys indicates a loss of 14.1 million cubic meters (-3.1 cm/yr) of sediment during this time period, representing an approximately three-fold acceleration of the rate that was observed...

2010, Marine Geology (275) 166-177
The chemical and isotopic compositions of sedimentary organic matter (SOM) from two mid-slope sites of the northern Cascadia margin were investigated during Integrated Ocean Drilling Program (IODP) Expedition 311 to elucidate the organic matter origins and identify potential microbial contributions to SOM. Gas hydrate is present at both locations (IODP...

2010, Marine Ornithology: Journal of Seabird Research and Conservation (38) 111-117
The seasonal and spatial demographics are summarized for seabirds killed incidentally during gear modification trials for a demersal longline fishery in the Bering Sea. We examined 417 carcasses, including Northern Fulmar Fulmarus glacialis (n = 205), Glaucous-winged Gull Larus glaucescens (n = 103), Short-tailed Shearwater Puffinus tenuirostris (n = 48),...
