Identification of P. infestan’s elusive center of origin is critical to
understanding the mechanisms of repeated global emergence of
this pathogen....
Corals provide a diversity of ecosystem services, are among the most biologically diverse ecosystems on Earth, and directly support ~500 million people globally; however, corals are increasingly experiencing significant threats and are undergoing severe bleaching events as the result of the warming climate. Using a two-year data set surrounding a...
Image-based dietary intake assessment (IBDIA) is a new way by which the accuracy of dietary assessment can be improved through the use of digital images of food. The ability of nutrition and dietetics students and interns to accurately interpret images for diet intake assessment is currently unknown. An online survey...
This study focused on the potential water and energy savings from implementing a revised schedule of a recirculation pump connected to a condensing gas tankless water heater located in a study home in Portland, Oregon. The existing recirculation pump activation schedule was studied for its impact on the overall water...
Yeast culture supplementation has been used to improve the health and performance of dairy cows for the last 25 years. To evaluate the effect of a Saccharomyces cerevisiae fermentation product (Diamond V Original XP™) on the health and production of peripartal Holstein cows, two research studies were conducted.
The first...
Growth models developed by Pennsylvania State University (Penn State) extension
services for Holstein and Jersey heifer height and weight were evaluated using OSU dairy
herd heifer data. The purpose of this study was to determine the ability of the models to
predict heights and weights of heifers in the OSU...
A new Phytophthora species was detected (i) in the USA, infecting foliage of Kalmia latifolia, (ii) in substrate underneath Pieris, and (iii) in Germany in soil samples underneath Aesculus hippocastanum showing disease symptoms. The new species Phytophthora obscura sp. nov. is formally named based on phylogenetic analysis, host range, Kochs...
Consistent with its charge under Oregon House Bill 3543, the Oregon Climate Change Research Institute (OCCRI) conducts a biennial assessment of the state of climate change science, including biological, physical, and social science, as it relates to Oregon and the likely effects of climate change on Oregon. This fifth Oregon...
The concept of nature as capital is gaining visibility in policies and practices in both the public and private sectors. This change is due to an improved ability to assess and value ecosystem services, as well as to a growing recognition of the potential of an ecosystem services approach to...
