White rot, caused by Sclerotium cepivorum, is a serious disease that causes significant yield losses in Allium production. The pathogen persists in soil as sclerotia, which germinate in response to sulfur compounds in Allium root exudates. This study was aimed at investigating the potential of early-terminated Allium bait crops to...
Molecular phylogenetic and chemical analyses, and morphological characterization of collections of North American Paraisaria specimens support the description of two new species and two new combinations for known species. P. cascadensis sp. nov. is a pathogen of Cyphoderris (Orthoptera) from the Pacific Northwest USA and P. pseudoheteropoda sp. nov. is...
Anadromous Oncorhynchus mykiss (steelhead) express diverse migratory behaviors and life history strategies. Adult migration timing diversity within steelhead is often categorized into divergent early- and late-migration phenotypes. On the Rogue River in Oregon, adult steelhead return from the ocean during distinct early-summer, late-summer, and winter runs. Additionally, some juvenile steelhead...
To evaluate and monitor insecticide resistance in onion thrips Thrips tabaci on onion (Allium cepa), we conducted a study using three field populations in the Treasure Valley of eastern Oregon and southwestern Idaho using the insecticides Lannate (methomyl) and Exirel (cyantraniliprole). To evaluate these two insecticides, biological assays were conducted...
In the United States, the wild horse population exceeds the recommended carrying capacity by about 60,000 horses.
• Current contraceptive methods include: surgical (removal of ovaries), hormonal (progesterone, GnRH), and immunologic (porcine zona pellucida, GnRH).
• SPACA3 is a sperm surface membrane protein involved in sperm-egg plasma membrane adhesion and...
These data were all collected in summer 2021 at Hinkle Creek watershed, a headwater ecosystem in a managed forest landscape in western Oregon. The data set has two components. The first component of the data set includes information about age 1 and older fish collected from two sections of the...
Pawpaw is the largest indigenous fruit in North America, native to Ontario, Canada and 26 midwestern and eastern states, yet its high value as a niche crop has been met with limited cultivation in Oregon, Washington, northern California, Idaho, and western Montana (Jones & Layne, n.d.). Cultivation of Pacific Northwest...
A critical barrier to effective management of deep-sea resources is a lack of understanding by society of the benefits received from the oceans. To address this knowledge gap, we applied an iterative design-based research methodology to evaluate (1) how to effectively use an exhibit to increase public literacy of the...
