Abstract:: The epiphytic lichen Letharia vulpina has been commonly sampled in-situ for nitrogen (N) deposition biomonitoring studies but has never before been transplanted for this purpose. In the high-elevation wilderness areas of southern California Letharia vulpina is generally uncommon, making in-situ sampling difficult. In this study, we compared thallus N accumulation...

Creator:: Buckland, Kristine and Ocamb, Cynthia M.
Abstract:: Sweet corn and snap bean production, amongst other vegetable crops grown in the Willamette Valley of Oregon, are impacted by soilborne diseases caused by Fusarium species. The decline in sweet corn yields due to Fusarium crown and stalk node rot as well as root rot in snap bean and sweet...

Abstract:: Data from mark-recapture study on cinnabar moths conducted at Cogswell Foster, OR, from 1986-05-29 through 1986-06-12. Data on captured and marked moths includes a number identifier, gender, wing wear (low, high), post-release behavior (mobile or immobile), capture/recapture locations (X/Y coordinates of study area, plot number, and categorical location relative to...

Creator:: Kovasi, Adrienne I.
Abstract:: All the datasets used in Kovasi's (2022) masters thesis. Chapter 2: The datasets are elemental concentrations for 25 elements from samples of the saxicolous lichens Umbilicaria phaea (n = 51), Rhizoplaca melanophthalma (n = 20), and the epiphytic lichen Letharia vulpina (n = 16) from the southern Sierra Nevada and...

Creator:: McCune, Bruce and Antos, Joseph A.
Abstract:: We sampled vegetation, bryophytes, lichens, environment, and stand dynamics in 56 plots in the Swan Valley, Montana in 1975-1978. The data include complete inventory of trees in 375 m2 plots, with whole-plot ocular estimates of plant cover by species, transect sampling of the ground layer bryophytes and lichens with microplots,...

Abstract:: Hyperspectral images were taken in a lab setting from wheat leaves and in situ from agricultural wheat fields and disease nursery. The goal of this research was to find infection of soilborne wheat mosaic virus in wheat for early detection using digital imagery, i.e., either hyperspectral or multispectral.

Abstract:: The role of small secreted peptides in plant defense responses to viruses has been seldom investigated. Here, we report a role for potato (Solanum tuberosum) PIP1, a gene predicted to encode a member of the PAMP-induced peptide (PIP) family, in the response of potato to potato virus Y infection (PVY)....

Abstract:: Clubroot, caused by Plasmodiophora brassicae, affects all species of the Crucifer family, including wild mustard. It is a fungus-like microorganism that can persist in soil in the form of durable resting spores for 18 years or longer after an infected crop. These resting spores can be spread through any means...

Abstract:: Sclerotinia sclerotiorum (causal agent of white mold) can cause serious economic losses in snap bean production as well as many other crops. Spores are produced in apothecia (mushroom-like structures) that develop from over-wintering sclerotia in the soil. Sclerotia are long-lived, durable hyphal survival structures produced by the fungus and they...

Creator:: Ocamb, Cynthia M.
Abstract:: Sweet corn is susceptible to various pathogenic Fusarium species and has been long known to be subject to early season diseases of seed rot and seedling blight as well as root rot and later season problems with stalk rot and ear rots. More recently, fields in the Willamette Valley of...

Abstract:: The wine grape industry is rapidly growing in Oregon. By the year 2005, we could predict that Oregon will have over 10,000 acres in wine grape production. At a meeting last year, the Grapevine Improvement Committee acknowledged that little was known about the presence of potential pest and beneficial insects...
