Effect of imperfect detectability on adaptive and conventional sampling: Simulated sampling of freshwater mussels in the upper Mississippi River
D. R. Smith, B. R. Gray, T.J. Newton, D. Nichols
2010, Environmental Monitoring and Assessment (170) 499-507
Adaptive sampling designs are recommended where, as is typical with freshwater mussels, the outcome of interest is rare and clustered. However, the performance of adaptive designs has not been investigated when outcomes are not only rare and clustered but also imperfectly detected. We address this combination of challenges using data...

High tsunami frequency as a result of combined strike-slip faulting and coastal landslides
M.J. Hornbach, N. Braudy, R.W. Briggs, M.-H. Cormier, M.B. Davis, J.B. Diebold, N. Dieudonne, R. Douilly, C. Frohlich, S.P.S. Gulick, H. E. Johnson III, P. Mann, C. McHugh, K. Ryan-Mishkin, C.S. Prentice, L. Seeber, C.C. Sorlien, M.S. Steckler, S.J. Symithe, F. W. Taylor, J. Templeton
2010, Nature Geoscience (3) 783-788
Earthquakes on strike-slip faults can produce devastating natural hazards. However, because they consist predominantly of lateral motion, these faults are rarely associated with significant uplift or tsunami generation. And although submarine slides can generate tsunami, only a few per cent of all tsunami are believed to be triggered in this...
Geochemical and mineralogical evidence for Sahara and Sahel dust additions to Quaternary soils on Lanzarote, eastern Canary Islands, Spain
D.R. Muhs, J. Budahn, G. Skipp, J.M. Prospero, D. Patterson, E. Arthur Bettis III
2010, Terra Nova (22) 399-410
Africa is the most important source of dust in the world today, and dust storms are frequent on the nearby Canary Islands. Previous workers have inferred that the Sahara is the most important source of dust to Canary Islands soils, with little contribution from the Sahel region. Soils overlying a...
Locating non-volcanic tremor along the San Andreas Fault using a multiple array source imaging technique
T. Ryberg, C.H. Haberland, G. S. Fuis, W.L. Ellsworth, D.R. Shelly
2010, Geophysical Journal International (183) 1485-1500
Non-volcanic tremor (NVT) has been observed at several subduction zones and at the San Andreas Fault (SAF). Tremor locations are commonly derived by cross-correlating envelope-transformed seismic traces in combination with source-scanning techniques. Recently, they have also been located by using relative relocations with master events, that is low-frequency earthquakes that...
Patterns of ancestry and genetic diversity in reintroduced populations of the slimy sculpin: Implications for conservation
D.D. Huff, L.M. Miller, B. Vondracek
2010, Conservation Genetics (11) 2379-2391
Reintroductions are a common approach for preserving intraspecific biodiversity in fragmented landscapes. However, they may exacerbate the reduction in genetic diversity initially caused by population fragmentation because the effective population size of reintroduced populations is often smaller and reintroduced populations also tend to be more geographically isolated than native populations....
Holocene aggradation of the Dry Tortugas coral reef ecosystem
J. C. Brock, M. Palaseanu-Lovejoy, R.Z. Poore, A. Nayegandhi, C. W. Wright
2010, Coral Reefs (29) 857-868
Radiometric age dating of reef cores acquired at the Dry Tortugas coral reef ecosystem (DTCRE) was merged with lidar topographic mapping to examine Holocene reef development linked to spatial variation in growth and erosion under the control of sea level. Analysis of variance of lidar topography confirmed the presence of...

J. Miao, M.C. Barnhart, Eric L. Brunson, Douglas K. Hardesty, Christopher G. Ingersoll, Ning Wang
2010, Environmental Toxicology and Chemistry (29) 2112-2116
Acute 96-h ammonia toxicity to three-month-old juvenile mussels (Lampsilis siliquoidea) was evaluated in four treatments (water-only, water-only with feeding, water and soil, and water and sand) using an exposure unit designed to maintain consistent pH and ammonia concentrations in overlying water and in pore water surrounding the substrates. Median effect...
Impact of sampling techniques on measured stormwater quality data for small streams
R. D. Harmel, R.M. Slade Jr., R.L. Haney
2010, Journal of Environmental Quality (39) 1734-1742
Science-based sampling methodologies are needed to enhance water quality characterization for setting appropriate water quality standards, developing Total Maximum Daily Loads, and managing nonpoint source pollution. Storm event sampling, which is vital for adequate assessment of water quality in small (wadeable) streams, is typically conducted by manual grab or integrated...
Seeding Method Influences Warm-Season Grass Abundance and Distribution but not Local Diversity in Grassland Restoration
K.A. Yurkonis, B.J. Wilsey, K.A. Moloney, P. Drobney, D.L. Larson
2010, Restoration Ecology (18) 344-353
Ecological theory predicts that the arrangement of seedlings in newly restored communities may influence future species diversity and composition. We test the prediction that smaller distances between neighboring seeds in drill seeded grassland plantings would result in lower species diversity, greater weed abundance, and larger conspecific patch sizes than otherwise...
Controls on biochemical oxygen demand in the upper Klamath River, Oregon
Annett B. Sullivan, Dean M. Snyder, Stewart A. Rounds

Quantifying rock uplift rates using channel steepness and cosmogenic nuclide–determined erosion rates: Examples from northern and southern Italy
Andrew J. Cyr, Darryl E. Granger, Valerio Olivetti, Paola Molin
2010, Lithosphere (2) 188-198
Rock uplift rates can be difficult to measure over 103–105 yr time scales. If, however, a landscape approaches steady state, where hillslope erosion and rock uplift rates are steady and locally similar, then it should be possible to quantify rock uplift rates from hillslope erosion rates. Here, we test this prediction...
The age of the Steens reversal and the Columbia River Basalt Group
Nicholas A. Jarboe, Robert S. Coe, Paul R. Renne, Jonathan M. G. Glen
2010, Chemical Geology (274) 158-168
The Columbia River Basalt Group (CRBG) eruptions have a well-defined relative magnetostratigraphy but have not been definitively correlated to the geomagnetic polarity time scale. 40Ar/39Ar ages are presented from lavas erupted in the R0 through N1magnetozones of the CRBG and in the transition between R0 and N0. Four ages from transitionally magnetized lava flows at Steens Mountain,...

A practitioner's tool for assessing glide crack activity
Jordy Hendrikx, Erich H. Peitzsch, Daniel B. Fagre
2010, Conference Paper, Proceedings, 2010 International Snow Science Workshop
Glide cracks can result in full-depth glide avalanche release. Avalanches from glide cracks are notoriously difficult to forecast, but are a reoccurring problem in a number of different avalanche forecasting programs across a range of snow climates. Despite this, there is no consensus for how to best manage, mitigate, or...
Characterizing wet slab and glide slab avalanche occurrence along the Going-to-the-Sun Road, Glacier National Park, Montana, USA
Erich H. Peitzsch, Jordy Hendrikx, Daniel B. Fagre, Blase Reardon
2010, Conference Paper, Proceedings: 2010 international snow science workshop
Wet slab and glide slab snow avalanches are dangerous and yet can be particularly difficult to predict. Both wet slab and glide slab avalanches are thought to depend upon free water moving through the snowpack but are driven by different processes. In Glacier National Park, Montana, both types of avalanches...
