Comments Regarding the Binary Power Law for Heterogeneity of Disease Incidence

Creator:: Turechek, W. W., Madden, L. V., and Gent, D. H.
Abstract:: The binary power law (BPL) has been successfully used to characterize heterogeneity (overdispersion or small-scale aggregation) of disease incidence for many plant pathosystems. With the BPL, the log of the observed variance is a linear function of the log of the theoretical variance for a binomial distribution over the range...

Development of a grower-conducted inoculum detection assay for management of grape powdery mildew

Creator:: Thiessen, L. D., Keune, J. A., Neill, T. M., Turechek, W. W., Grove, G. G., and Mahaffee, W. F.
Abstract:: Management of grape powdery mildew (Erysiphe necator) and other polycyclic diseases often relies on calendar-based pesticide application schedules that assume the presence of inoculum. An inexpensive, loop-mediated isothermal amplification (LAMP) assay was designed to quickly detect airborne inoculum of E. necator to determine when to initiate a fungicide application programme....

Association of Spring Pruning Practices with Severity of Powdery Mildew and Downy Mildew on Hop

Creator:: Gent, David H., Nelson, Mark E., Grove, Gary G., Mahaffee, Walter F., Turechek, William W., and Woods, Joanna L.
Abstract:: Downy mildew (caused by Pseudoperonospora humuli) and powdery mildew (caused by Podosphaera macularis) are important diseases of hop in the Pacific Northwest United States, and cultural practices may affect the severity of both diseases. The association of spring pruning quality and timing with severity of downy mildew and powdery mildew...

The social geometry of collaborative flood risk management: a hydrosocial case study of Tillamook County, Oregon

Creator:: Haeffner, Melissa and Hellman, Dana
Abstract:: Coastal and riparian flooding are costly and disruptive natural hazards and already a regular part of life in some areas of the USA. Flooding events caused by sea-level rise and climate change are expected to increase in frequency and severity in the future, creating social, ecological, and economic problems at...

Heat and Energy Balances in the Upper Ocean at 50°N, 140°W during November 1980 (STREX)

Creator:: Paduan, S. D. and DeSzoeke, R. A.
Abstract:: Subsurface temperature data and surface meteorological data are analyzed from thermistor chain moorings deployed near 50°N, 140°W during the Storm Transfer and Response Experiment (STREX). The upper-ocean heat and potential energy (PE) contents to 90 m are examined for an 18-day period and their changes compared to the sources and...

Long-term temperature records following the M[subscript w] 7.9 Wenchuan (China) earthquake are consistent with low friction

Creator:: Li, Haibing, Xue, Lian, Brodsky, Emily E., Mori, James J., Fulton, Patrick M., Wang, Huang, Kano, Yasuyuki, Yun, Kun, Harris, Robert N., Gong, Zheng, Li, Chenglong, Si, Jialiang, Sun, Zhiming, Pei, Junling, Zheng, Yong, and Xu, Zhiqin
Abstract:: Knowledge of the shear stress on a fault during slip is necessary for a physically-based understanding of earthquakes. Borehole temperature measurements inside the fault zone immediately after an earthquake can record the energy dissipated by this stress. In the first Wenchuan Earthquake Fault Zone Scientific Drilling Project hole (Sichuan province,...

Emergence of Groundnut ringspot virus and Tomato chlorotic spot virus in Vegetables in Florida and the Southeastern United States

Creator:: Webster, Craig G., Frantz, Galen, Reitz, Stuart R., Funderburk, Joseph E., Mellinger, H. Charles, McAvoy, Eugene, Turechek, William W., Marshall, Spencer H., Tantiwanich, Yaowapa, McGrath, Margaret T., Daughtrey, Margery L., and Adkins, Scott
Abstract:: Groundnut ringspot virus (GRSV) and Tomato chlorotic spot virus (TCSV) are two emerging tospoviruses in Florida. In a survey of the southeastern United States, GRSV and TCSV were frequently detected in solanaceous crops and weeds with tospovirus-like symptoms in south Florida, and occurred sympatrically with Tomato spotted wilt virus (TSWV)...

Benthic macroinvertebrates sampled above and below Cougar Dam

Creator:: Murphy, Christina A, Johnson, Sherri L., Gerth, William, Pierce, Todd, and Taylor, Gregory
Abstract:: This dataset accompanies the manuscript Unintended consequences of selective water withdrawals from reservoirs alter downstream macroinvertebrate communities in Water Resources Research. Benthic macroinvertebrates were collected from samples taken annually during the first two weeks of August from 2002-2007 and again in 2017 at six sites in the South Fork McKenzie...
