A.M.A. Harding, John F. Piatt, G.V. Byrd, Scott A. Hatch, N. B. Konyukhov, E.U. Golubova, J.C. Williams
2005, Journal of Wildlife Management (69) 1279-1296
It is difficult to survey crevice-nesting seabirds because nest-sites are hard to identify and count, and the number of adult birds attending a colony can be extremely variable within and between days. There is no standardized method for surveying crevice-nesting horned puffins (Fratercula corniculata), and consequently little is known...
Physical and chemical properties of submarine basaltic rocks from the submarine flanks of the Hawaiian Islands
Hisayoshi Yokose, Peter W. Lipman, Toshiya Kanamatsu
2005, Marine Geology (219) 173-193
To evaluate physical and chemical diversity in submarine basaltic rocks, approximately 280 deep submarine samples recovered by submersibles from the underwater flanks of the Hawaiian Islands were analyzed and compared. Based on observations from the submersibles and hand specimens, these samples were classified into three main occurrence types (lavas, coarse-grained...

N.C. Davatzes, A. Aydin
2005, Book chapter, Faults, Fluid Flow, and Petroleum Traps
We examined the distribution of fault rock and damage zone structures in sandstone and shale along the Moab fault, a basin-scale normal fault with nearly 1 km (0.62 mi) of throw, in southeast Utah. We find that fault rock and damage zone structures vary along strike and dip. Variations are...
An integrated approach to flood hazard assessment on alluvial fans using numerical modeling, field mapping, and remote sensing
J.D. Pelletier, L. Mayer, P. A. Pearthree, P.K. House, K.A. Demsey, J.K. Klawon, K.R. Vincent
2005, Geological Society of America Bulletin (117) 1167-1180
Millions of people in the western United States live near the dynamic, distributary channel networks of alluvial fans where flood behavior is complex and poorly constrained. Here we test a new comprehensive approach to alluvial-fan flood hazard assessment that uses four complementary methods: two-dimensional raster-based hydraulic modeling, satellite-image change detection,...

C.J. Mayers, Brian J. Andraski, C.A. Cooper, S.W. Wheatcraft, David A. Stonestrom, R. L. Michel
2005, Vadose Zone Journal (4) 967-976
Understanding transport of tritium (3H) in unsaturated zones is critical to evaluating options for waste isolation. Tritium typically is a large component of low-level radioactive waste (LLRW). Studies at the U.S. Geological Survey's Amargosa Desert Research Site (ADRS) in Nevada investigate 3H transport from a closed LLRW facility. Two boreholes...
Ranking the risk of wildlife species hazardous to military aircraft
E. J. Zakrajsek, John A. Bissonette
2005, Wildlife Society Bulletin (33) 258-264
Collisions between birds and aircraft (birdstrikes) pose a major threat to aviation safety. Different species pose different levels of threat; thus, identification of the most hazardous species can help managers identify the level of hazard and prioritize mitigation efforts. Dolbeer et al. (2000) assessed the hazard posed by birds to...
Native fish sanctuaries of the lower Colorado River: Cibola High Levee Pond, Desert Pupfish Pond
G. Mueller
2005, General Information Product 9
Historically, the Colorado River was one of the most formidable rivers in the world. Each spring, melting snow from the mountains scoured the desert landscape moving millions of tons of sediment to the sea. The Grand Canyon lays testament to its erosive nature. Summer heat would bring seasonal droughts, reducing...

Survival of captive-reared Puerto Rican Parrots released in the Caribbean National Forest
Thomas H. White Jr., Jaime A. Collazo, Francisco Vilella
2005, Condor (107) 424-432
We report first-year survival for 34 captive-reared Puerto Rican Parrots (Amazona vittata) released in the Caribbean National Forest, Puerto Rico between 2000 and 2002. The purpose of the releases were to increase population size and the potential number of breeding individuals of the sole extant wild population, and to refine...
Do wintering Harlequin Ducks forage nocturnally at high latitudes?
Daniel Rizzolo, Daniel Esler, Daniel D. Roby, Robert L. Jarvis
2005, Condor (107) 173-177
We monitored radio-tagged Harlequin Ducks (Histrionicus histrionicus) to determine whether nocturnal feeding was part of their foraging strategy during winter in south-central Alaska. Despite attributes of our study site (low ambient temperatures, harsh weather, short day length) and study species (small body size, high daytime foraging rates) that would be...
Biogeochemical and metabolic responses to the flood pulse in a semiarid floodplain

Flood pulse inundation of riparian forests alters rates of nutrient retention and organic matter processing in the aquatic ecosystems formed in the forest interior. Along the Middle Rio Grande (New Mexico, USA), impoundment and levee construction have created riparian forests that differ in their inter-flood intervals (IFIs) because some floodplains...
Planning for bird conservation: a tale of two models
Douglas H. Johnson, Maiken Winter
2005, General Technical Report GTR-PSW-191
Planning for bird conservation has become increasingly reliant on remote sensing, geographical information systems, and, especially, models used to predict the occurrence of bird species as well as their density and demographics. We address the role of such tools by contrasting two models used in bird conservation. One, the Mallard...
Alunite in the Pascua-Lama high-sulfidation deposit: Constraints on alteration and ore deposition using stable isotope geochemistry
C. L. Deyell, R. Leonardson, R. O. Rye, J. F. H. Thompson, T. Bissig, D. R. Cooke
2005, Economic Geology (100) 131-148
The Pascua-Lama high-sulfidation system, located in the El Indio-Pascua belt of Chile and Argentina, contains over 16 million ounces (Moz) Au and 585 Moz Ag. The deposit is hosted primarily in granite rocks of Triassic age with mineralization occurring in several discrete Miocene-age phreatomagmatic breccias and related fracture networks. The...

2005, Western Birds (36) 64-66
A simple, papillary cystic adenocarcinoma of the mammary gland with metastases to the internal iliac and mesenteric lymph nodes, liver, and spleen was observed in a 12 to 13 year old female black-footed ferret (Mustela nigripes). Histologically, the tumor was aggressive, and lymphatic invasion was found. Attempts at virus isolation...
An efficient strategy to estimate intensity and prevalence: Sampling metacercariae in fishes
Jenny C. Shaw, Leopoldina Aguirre-Macedo, Kevin D. Lafferty
2005, Journal of Parasitology (91) 515-521
Accurate estimates of population-level parameters of parasites, such as prevalence and mean intensity, require large sample sizes. The processing of such samples becomes an overwhelming task when parasites are abundant, as with trematode metacercariae in fishes. In the present study, a subsampling method reduced processing time while maintaining an accurate...
Climate change and amphibians
P.S. Corn
2005, Animal Biodiversity and Conservation (28) 59-67
Amphibian life histories are exceedingly sensitive to temperature and precipitation, and there is good evidence that recent climate change has already resulted in a shift to breeding earlier in the year for some species. There are also suggestions that the recent increase in the occurrence of El Niño events has...
Fire history of the San Francisco East Bay region and implications for landscape patterns
Jon E. Keeley
2005, International Journal of Wildland Fire (14) 285-296
The San Francisco East Bay landscape is a rich mosaic of grasslands, shrublands and woodlands that is experiencing losses of grassland due to colonization by shrubs and succession towards woodland associations. The instability of these grasslands is apparently due to their disturbance-dependent nature coupled with 20th century changes in fire...
Should we expect population thresholds for wildlife disease?
James O. Lloyd-Smith, P.C. Cross, C.J. Briggs, M. Daugherty, W.M. Getz, J. Latto, M. Sanchez, A. Smith, A. Swei
2005, Trends in Ecology and Evolution (20) 511-519
Host population thresholds for invasion or persistence of infectious disease are core concepts of disease ecology, and underlie on-going and controversial disease control policies based on culling and vaccination. Empirical evidence for these thresholds in wildlife populations has been sparse, however, though recent studies have narrowed this gap. Here we...
Flight speeds of northern pintails during migration determined by satellite telemetry

2005, The Wilson Bulletin (117) 364-374
Speed (km/hr) during flight is one of several factors determining the rate of migration (km/ day) and flight range of birds. We attached 26-g, back-mounted satellite-received radio tags (platform transmitting terminals; PTTs) to adult female Northern Pintails (Anas acuta) during (1) midwinter 2000–2003 in the northern Central Valley of...
Trematodes in snails near raccoon latrines suggest a final host role for this mammal in California Salt Marshes
K. D. Lafferty, E. J. Dunham
2005, Journal of Parasitology (91) 474-476
Of the 18 trematode species that use the horn snail, Cerithidea californica, as a first intermediate host, 6 have the potential to use raccoons as a final host. The presence of raccoon latrines in Carpinteria Salt Marsh, California, allowed us to investigate associations between raccoons and trematodes in snails. Two...
Duelling timescales of host mixing and disease spread determine invasion of disease in structured populations
P.C. Cross, James O. Lloyd-Smith, P.L.F. Johnson, W.M. Getz
2005, Ecology Letters (8) 587-595
The epidemic potential of a disease is traditionally assessed using the basic reproductive number, R0. However, in populations with social or spatial structure a chronic disease is more likely to invade than an acute disease with the same R0, because it persists longer within each group and allows for more...
A space‐for‐time substitution reveals the long‐term decline in genotypic diversity of a widespread salt marsh plant, Spartina alterniflora, over a span of 1500 years
S.E. Travis, M.W. Hester
2005, Journal of Ecology (93) 417-430
Clonal populations face a trade‐off between sexual recruitment and vegetative growth and, once established, may undergo continuous declines in genotypic diversity if their sexual recruits make poor competitors. The geological history of delta formation in the Lower Mississippi River Valley was used to age eight S. alterniflora marshes for use in a...
