Late blight, caused by Phytophthora infestans, is a devastating problem to potato production in many parts of the world. While the foliar phases of this disease are well characterized, tuber infection, leading to quality losses and disease perpetuation, is less well understood. Experiments were conducted during 1998 and 1999 in...
Leaves of healthy strawberry plants were inoculated with either vinclozolin-sensitive or vinclozolin-resistant isolates of Botrytis cinerea at one of three concentrations: 5x104, 1x105, and 5x105 conidia/ml. One week following inoculation, representative leaves were harvested and cut into 9mm2 leaf pieces. Some pieces were immediately plated onto selective Botrytis medium while...
In this study, the gene expression levels between 6 month old mice and 26 month
old mice were compared. The purpose of this research was to identify genes that are
differentially regulated due to aging. The results showed 148 significantly differentiated
genes in the analysis of a total of 44,170...

Nutrition effects productivity of grouse. Females that obtain
high nutrient diets in spring produce larger clutches and larger, more
viable chicks than hens on less nutritious diets. Grouse select high
nutrient foods to help ensure proper nutrition. Reduced productivity
accounted for the decline of sage grouse (Centrocercus urophasianus)
populations in...
The purpose of this research was to compare two instructional
programs of inservice training on Personal Hygiene for hospital foodservice
employees for knowledge retention and cost effectiveness.
The two instructional methods used were lecture discussion with a
script and transparencies and the individual instruction with cassette
tape and slides.
The...
Pacific oysters (Crassostrea gigas), Alaska pink salmon (Oncorynchus gorbuscha) roe and chum salmon (Oncorynchus keta) fillets were treated with aqueous ozone in both pilot plant and commercial settings to determine its effect on shelf-life and microbial changes. The microbial quality was analyzed by conducting pyschrotrophic and coliform plate counts on...
Calcium (Ca) is an essential macronutrient that is increasingly recognized as a biogeochemical factor that influences ecosystem structure and function. Progress in understanding the sustainability of ecosystem Ca supply has been hampered by a lack of information on the various forms and pools of Ca in forest ecosystems. In particular,...
As GIS becomes more prominent in academic classrooms at all levels of education, the subject of geography and its related disciplines can be approached with a geospatial technology perspective, using new tools and lesson plans. The implementation of Google Earth in classrooms is just one example of this. Research was...
Acid deposition and repeated biomass harvest have decreased
soil calcium (Ca) availability in many temperate forests worldwide, yet
existing methods for assessing available soil Ca do not fully characterize
soil Ca forms. To account for discrepancies in ecosystem Ca budgets, it
has been hypothesized that the highly insoluble biomineral Ca...
Calcium oxalate (Ca oxalate) is an insoluble biomineral that forms in plants and fungi, and occurs in soils
across many types of ecosystems. Assessing how Ca oxalate may shape ecosystem Ca cycling requires
information on the distribution of Ca oxalate among plant biomass, detritus, and mineral soil, and how
it...
