Seeded Native Shrub Establishment on Disturbed Sites in Southwestern Wyoming

Critical wildlife habitat supporting mule deer, antelope, and sage grouse in high elevation rangeland and sagebrush ecosystems of southwest Wyoming is threatened by an expanding population and energy exploration and development. Our objective was to evaluate native shrub species establishment for restoration after disturbance. In October 2005, on a well-pad disturbance, 16 accessions of 12 native shrub species were drill-seeded in single species plots in a randomized complete block design with four replications. Also, two seed mixtures (Bridger and Shell) of grass, forb, and shrub species were broadcast- or drill-seeded, and one seed mixture (Shell) was hydro-seeded to separate areas outside of the replicated plots. Densities were sampled in September 2007. By 2007, nine of the 16 shrub accessions established in the replicated plots. Atriplex aptera had the greatest establishment at six plants/m2 followed by Atriplex canescens at four plants/m2. Establishment of the other seven accessions was similar and ranged from two to 0.4 plants/m2. Where the Bridger mix was broadcast seeded, Artemisia tridentata ssp. wyomingensis, Atriplex aptera, and Krascheninnikovia lanata establishment was estimated at 10,000, 6,770, and 1,120 plants/ha, respectively. Where drill seeded, establishment of the three shrubs was 0, 4,480, and 2,240 plants/ha, respectively. Where the Shell mix was broadcast seeded, Artemisia tridentata ssp. wyomingensis, Krascheninnikovia lanata, and Atriplex canescens establishment was estimated at 21,300, 4,500, and 4,500 plants/ha, respectively. Where drill seeded, establishment for the three species was 7,800, 10,000, and 1,100 plants/ha, respectively. Where the Shell mix was hydro-seeded, only Krascheninnikovia lanata established at 1,100 plants/ha

Cooperative Evaluation of Inner Mongolia, PRC, Grassland Germplasm in the Western USA

Replicated dryland studies were established at three USDA, NRCS, Plant Materials Centers in the USA northern intermountain west by Chinese and American scientists. Forty-six Asian and 16 USA grasses, legumes, and shrubs were included. These plantings were evaluated for vigor, percent stand, and foliage height in 1994 and 1995, and for biomass production in 1995. Generally, USA grasses outperformed Asian grasses, while Inner Mongolian legumes show the highest potential for use in the intermountain west

Expression of Interest: The Atmospheric Neutrino Neutron Interaction Experiment (ANNIE)

Similar techniques might also be useful in the detection of supernova neutrinos. Accurate determination of neutron tagging efficiencies will require a detailed understanding of the number of neutrons produced by neutrino interactions in water as a function of momentum transferred. We propose the Atmospheric Neutrino Neutron Interaction Experiment (ANNIE), designed to measure the neutron yield of atmospheric neutrino interactions in gadolinium-doped water. An innovative aspect of the ANNIE design is the use of precision timing to localize interaction vertices in the small fiducial volume of the detector. We propose to achieve this by using early production of LAPPDs (Large Area Picosecond Photodetectors). This experiment will be a first application of these devices demonstrating their feasibility for Water Cherenkov neutrino detectors

Reconstructing the evolution of the submarine Monterey Canyon System from Os, Nd, and Pb isotopes in hydrogenetic Fe-Mn crusts

The definitive version was published in Geochemistry, Geophysics, Geosystems 18 (2017): 3946–3963, doi:10.1002/2017GC007071.The sources of terrestrial material delivered to the California margin over the past 7 Myr were assessed using 187Os/188Os, Nd, and Pb isotopes in hydrogenetic ferromanganese crusts from three seamounts along the central and southern California margin. From 6.8 to 4.5 (±0.5) Ma, all three isotope systems show more radiogenic values at Davidson Seamount, located near the base of the Monterey Canyon System, than in Fe-Mn crusts from the more remote Taney and Hoss Seamounts. At the Taney Seamounts, approximately 225 km farther offshore from Davidson Seamount, 187Os/188Os values, but not Pb and Nd isotope ratios, also deviate from the Cenozoic seawater curve toward more radiogenic values from 6.8 to 4.5 (±0.5) Ma. However, none of the isotope systems in Fe-Mn crusts deviate from seawater at Hoss Seamount located approximately 450 km to the south. The regional gradients in isotope ratios indicate that substantial input of dissolved and particulate terrestrial material into the Monterey Canyon System is responsible for the local deviations in the seawater Nd, Pb, and Os isotope compositions from 6.8 to 4.5 (±0.5) Ma. The isotope ratios recorded in Fe-Mn crusts are consistent with a southern Sierra Nevada or western Basin and Range provenance of the terrestrial material which was delivered by rivers to the canyon. The exhumation of the modern Monterey Canyon must have begun between 10 and 6.8 ± 0.5 Ma, as indicated by our data, the age of incised strata, and paleo-location of the Monterey Canyon relative to the paleo-coastline.Funding was provided by the United States Geological Survey Pacific Coastal and Marine Science Center Marine Minerals Group, the University of California Santa Cruz Scholarship for Re-Entry Women in Science, and the UCSC Earth and Planetary Science Department Waters Award.2018-05-1
