Honey bees are vital for our food production and ecosystem due to their critical pollination services. The beekeepers in the United States and worldwide have reported significant colony losses for over fifteen years. Several stressors are implicated in these colony declines, including parasites, diseases, poor nutrition, and pesticide exposure. There...
This edition contains research updates and a comprehensive list of publications summarizing research conducted by faculty of the Oregon Wine Research Institute at Oregon State University. Dr. Elizabeth Tomasino, OSU associate professor, and Quynh Phan, OSU doctoral candidate, open the newsletter with an article on Pinot noir wine lipid composition....
Anthropogenic induced climate change is predicted to alter distribution of existing plant populations. As plants migrate over space and time, populations often fragment and contract, affecting basic elements of population dynamics (e.g., population size, gene flow, genetic diversity, etc.). Little is known, however, how these impacts on plant species will...
Per- and polyfluoroalkyl substances (PFAS) are a group of anthropogenic compounds that are used ubiquitously in different industrial fields. However, concerns regarding the potential health impacts of PFAS, including perfluoroalkyl carboxylic acids
(PFCAs) and perfluoroalkyl sulfonates (PFSAs), has raised stakeholder interest regarding continued use of PFAS. Analytical methods for PFAS...

Aroma is one of the major components that determines the quality of wine and consumer acceptability. Fruitiness is a highly desirable aroma quality in white wines and has been well accepted by consumers across the globe. Tropical fruit aroma has been substantially studied in Sauvignon Blanc wines due to its...
The contributions of Palestinian women have historically been discredited and delegitimized. This has occurred both due to societal patriarchy, and due to patriarchal norms being exacerbated by the conditions of living under the violent Israeli occupation and settler colonialism. Yet in actuality, Palestinian women have played many diverse roles in...
This study investigated the impact of organic chromium (Cr) supplementation and flaxseed on live performance, carcass yield, serum metabolites, muscle lipid profile, histopathological aspects, and meat quality parameters. Ninety (n=90), day-old Cobb chicks were fed a corn-soybean meal-based diet containing 0% flaxseed (Control), 10% flaxseed (Diet 1) and Diet 1...
Oxylipins are a class of bioactive lipid metabolites derived from polyunsaturated fatty acids (PUFAs) via enzymatic and non-enzymatic pathways. In order to elucidate their overall biological effects, the knowledge of the entire oxylipin profile is needed as oxylipins can have similar or opposing effects in regard to inflammatory events. Their...
Per- and polyfluoroalkyl substances (PFAS) are anthropogenic surfactants that have recently been identified as persistent organic pollutants. These so called “Forever Chemicals” have been detected in drinking waters, ground waters, soils, and consumer and industrial products globally; with environmental impacts stretching into the artic, far from known PFAS sources. The...
