Temporal and spatial variation of atmospherically deposited organic contaminants at high elevation in Yosemite National Park, California, USA

Creator:: Bradford, David F., Stanley, Kerri A., Tallent, Nita G., Sparling, Donald W., Nash, Maliha S., Knapp, Roland A., McConnell, Laura L., and Simonich, Staci L. Massey
Abstract:: Contaminants used at low elevation, such as pesticides on crops, can be transported tens of kilometers and deposited in adjacent mountains in many parts of the world. Atmospherically deposited organic contaminants in the Sierra Nevada Mountains of California, USA, have exceeded some thresholds of concern, but the spatial and temporal...

Investigating the impact of chronic atrazine exposure on sexual development in zebrafish

Creator:: Corvi, Margaret M., Stanley, Kerri A., Peterson, Tracy S., Kent, Michael L., Feist, Stephen W., La Du, Jane K., Volz, David C., Hosmer, Alan J., and Tanguay, Robert L.
Abstract:: Atrazine (ATZ) is a selective triazine herbicide used primarily for pre-emergent weed control in corn, sorghum and sugar cane production. It is one of the most widely used herbicides in North America. Some research published over the last decade suggests that chronic exposure to environmentally relevant ATZ concentrations can adversely...

Comparison of pressurized liquid extraction and matrix solid phase dispersion for the measurement of semi-volatile organic compound accumulation in tadpoles

Creator:: Stanley, Kerri, Simonich, Staci Massey, Bradford, David, Davidson, Carlos, and Tallent-Halsell, Nita
Abstract:: Analytical methods capable of trace measurement of semi-volatile organic compounds (SOCs) are necessary to assess the exposure of tadpoles to contaminants as a result of long-range and regional atmospheric transport and deposition. The following study compares the results of two analytical methods, one using pressurized liquid extraction (PLE) and the...

Effectiveness of an Antimicrobial Polymer to Decrease Contamination of Environmental Surfaces in the Clinical Setting

Creator:: Thom, Kerri A., Standiford, Harold C., Johnson, J. Kristie, Hanna, Nader, and Furuno, Jon P.
Abstract:: We performed a real-world, controlled intervention to investigate use of an antimicrobial surface polymer, MSDS Poly, on environmental contamination. Pathogenic bacteria were identified in 18 (90%) of 20 observations in treated rooms and 19 (83%) of 23 observations in untreated rooms (P = .67). MSDS Poly had no significant effect...

How much does the time lag between wildlife field-data collection and LiDAR-data acquisition matter for studies of animal distributions? A case study using bird communities

Creator:: Vierling, Kerri T., Swift, Charles E., Hudak, Andrew T., Vogeler, Jody C., and Vierling, Lee A.
Abstract:: Vegetation structure quantified by light detection and ranging (LiDAR) can improve understanding of wildlife occupancy and species-richness patterns. However, there is often a time lag between the collection of LiDAR data and wildlife data. We investigated whether a time lag between the LiDAR acquisition and field-data acquisition affected mapped wildlife...

Lidar-derived canopy architecture predicts brown creeper occupancy of two western coniferous forests

Creator:: Vogeler, Jody C., Hudak, Andrew T., Vierling, Lee A., and Vierling, Kerri T.
Abstract:: In western conifer-dominated forests where the abundance of old-growth stands is decreasing, species such as the Brown Creeper (Certhia americana) may be useful as indicator species for monitoring the health of old-growth systems because they are strongly associated with habitat characteristics associated with old growth and are especially sensitive to...

Improvements to an Empirical Parameterization of Heterogeneous Ice Nucleation and Its Comparison with Observations

Creator:: Phillips, Vaughan T. J., Demott, Paul J., Andronache, Constantin, Pratt, Kerri A., Prather, Kimberly A., Subramanian, R., and Twohy, Cynthia
Abstract:: A framework for an empirical parameterization (EP) of heterogeneous nucleation of ice crystals by multiple species of aerosol material in clouds was proposed in a 2008 paper by the authors. The present paper reports improvements to specification of a few of its empirical parameters. These include temperatures for onset of...

Risk of Acquiring Extended-Spectrum β-Lactamase–Producing Klebsiella Species and Escherichia coli from Prior Room Occupants in the Intensive Care Unit

Creator:: Ajao, Adebola O., Johnson, J. Kristie, Harris, Anthony D., Zhan, Min, McGregor, Jessina C., Thom, Kerri A., and Furuno, Jon P.
Abstract:: OBJECTIVE. To quantify the association between admission to an intensive care unit (ICU) room most recently occupied by a patient positive for extended-spectrum beta-lactamase (EBSL)-producing gram-negative bacteria and acquisition of infection or colonization with that pathogen. DESIGN. Retrospective cohort study. SETTING AND PATIENTS. The study included patients admitted to medical...

In Situ Chemical Characterization of Aged Biomass-Burning Aerosols Impacting Cold Wave Clouds

Creator:: Pratt, Kerri A., Heymsfield, Andrew J., Twohy, Cynthia, Murphy, Shane M., DeMott, Paul J., Hudson, James G., Subramanian, R., Wang, Zhien, Seinfeld, John H., and Prather, Kimberly A.
Abstract:: During the Ice in Clouds Experiment–Layer Clouds (ICE-L), aged biomass-burning particles were identified within two orographic wave cloud regions over Wyoming using single-particle mass spectrometry and electron microscopy. Using a suite of instrumentation, particle chemistry was characterized in tandem with cloud microphysics. The aged biomass-burning particles comprised ~30%–40% by number...

A fluorescein tracer release experiment in the hydrothermally active crater of Vailulu'u volcano, Samoa

Creator:: Hart, Stanley R., Staudigel, H., Koppers, Anthony A. P., and Girard, A. P.
Abstract:: On 3 April 2001, a 20 kg point source of fluorescein dye was released 30 m above the bottom of the active summit caldera of Vailulu’u submarine volcano, Samoa. Vailulu’u crater is 2000 m wide and at water depths of 600–1000 m, with the bottom 200 m completely enclosed; it...
