M. G. Knutson, L.A. Powell, R. K. Hines, M. A. Friberg, G.J. Niemi
2006, Condor (108) 301-314
Survival and reproduction directly affect population growth rate (lambda) making lambda a fundamental parameter for assessing habitat quality. We used field data, literature review, and a computer simulation to predict annual productivity and lambda for several species of landbirds breeding in floodplain and upland forests in the Midwestern United States....

2006, Photogrammetric Engineering and Remote Sensing (72) 1027-1035
The U.S. Geological Survey (USGS) has developed a 16-year time series of vegetation condition information for the conterminous United States and Alaska using 1 km Advanced Very High Resolution Radiometer (AVHRR) data. The AVHRR data have been processed using consistent methods that account for radiometric variability due to calibration uncertainty,...
Necropsy findings in American alligator late-stage embryos and hatchlings from northcentral Florida lakes contaminated with organochlorine pesticides
M. S. Sepulveda, Piero F. Del, J.J. Wiebe, H.R. Rauschenberger, T. S. Gross
2006, Journal of Wildlife Diseases (42) 56-73
Increased American alligator (Alligator mississippiensis) embryo and neonatal mortality has been reported from several northcentral Florida lakes contaminated with old-use organochlorine pesticides (OCPs). However, a clear relationship among these contaminants and egg viability has not been established, suggesting the involvement of additional factors in these mortalities. Thus, the main objective...
Strontium

2006, Mining Engineering (58) 57
China, Mexico, Spain and Turkey are the world's leading producers of celestite (strontium sulphate). These countries accounted for 98% of the total world production in 2005. For the same period, US apparent consumption of strontium decreased to 12.3 kt. Imports were 21.2 kt, of which 84% came from Mexico. Imports...
Tidal saltmarsh fragmentation and persistence of San Pablo Song Sparrows (Melospiza melodia samuelis): Assessing benefits of wetland restoration in San Francisco Bay

2006, Studies in Avian Biology 238-246
The San Pablo Song Sparrow (Melospiza melodia samuelis) is one of three morphologically distinct Song Sparrow subspecies in tidal marshes of the San Francisco Bay estuary. These subspecies are rare, because as the human population has grown, diking and development have resulted in loss of 79% of the historic tidal...

A reexamination of the Sudbury landing
D.S. Ross
2006, Icarus (183) 233-234
The arrival of the massive body that led to the Sudbury impact structure has been interpreted as a relatively gentle event, with temperatures not exceeding 1300 K on the basis of the presence of fullerene-caged helium. Such temperatures are well below the 10,000 K peaks suggested in large impact modeling,...

Coseismic and initial postseismic deformation from the 2004 Parkfield, California, earthquake, observed by global positioning system, electronic distance meter, creepmeters, and borehole strainmeters
J. Langbein, J.R. Murray, Hollice A. Snyder
2006, Bulletin of the Seismological Society of America (96)
Global Positioning System (GPS), electronic distance meter, creepmeter, and strainmeter measurements spanning the M 6.0 Parkfield, California, earthquake are examined. Using these data from 100 sec through 9 months following the main-shock, the Omori's law, with rate inversely related to time, l/t p and p ranging between 0.7 and 1.3,...

The wide spectral coverage and extensive spatial, temporal, and phase-angle mapping capabilities of the Visual Infrared Mapping Spectrometer (VIMS) onboard the Cassini-Huygens Orbiter are producing fundamental new insights into the nature of the atmospheres of Saturn and Titan. For both bodies, VIMS maps over time and solar phase angles provide...
Local thickening of the Cascadia forearc crust and the origin of seismic reflectors in the uppermost mantle
A.J. Calvert, K. Ramachandran, H. Kao, M. A. Fisher
2006, Tectonophysics (420) 175-188
Seismic reflection profiles from three different surveys of the Cascadia forearc are interpreted using P wave velocities and relocated hypocentres, which were both derived from the first arrival travel time inversion of wide-angle seismic data and local earthquakes. The subduction decollement, which is characterized beneath the continental shelf by a...
Evidence for preferential flow through sandstone aquifers in Southern Wisconsin
S.K. Swanson, J.M. Bahr, K. R. Bradbury, K.M. Anderson
2006, Sedimentary Geology (184) 331-342
Sandstones often escape extensive hydrogeologic characterization due to their high primary porosity and perceived homogeneity of permeability. This study provides evidence for laterally extensive, high permeability zones in the Tunnel City Group, an undeformed, Cambrian-aged sandstone unit that exists in the subsurface throughout much of central and southern Wisconsin, USA....

Lorraine E. Flint, David C. Buesch, Alan L. Flint
2006, Vadose Zone Journal (5) 480-492
Characterization of the physical and unsaturated hydrologic properties of subsurface materials is necessary to calculate flow and transport for land use practices and to evaluate subsurface processes such as perched water or lateral diversion of water, which are influenced by features such as faults, fractures, and abrupt changes in lithology....

B.K. Ackerson, L.A. Harveson
2006, Texas Journal of Science (58) 169-184
Despite the common occurrence of ringtails (Bassariscus astutus) few studies have been conducted to assess population characteristics. The objectives of this study were to determine (1) habitat selection, (2) home range, (3) denning characteristics, and (4) food habits of ringtails in the Trans Pecos region of west Texas. Seventeen ringtails...

J. C. Risley, J. S. Walder, R.P. Denlinger
2006, Natural Hazards (38) 375-390
The Usoi dam was created in the winter of 1911 after an enormous seismogenic rock slide completely blocked the valley of the Bartang River in the Pamir Mountains of southeastern Tajikistan. At present the dam impounds 17 million cubic meters of water in Lake Sarez. Flood volume and discharge estimates...

2006, Geochimica et Cosmochimica Acta (70) 5146-5161
Reduced sulfur species were studied to constrain isotopic exchange-mixing with synthetic polysulfide cross-linked macromolecules (PCLM), model sulfur containing molecules and natural sulfur-rich kerogen, asphalt and oil of the Dead Sea area. PCLM represents protokerogens that are rich in sulfur and thermally unstable. Mixing rates of PCLM with <a...
