The stereospecific reagent-controlled homologation (StReCH) of boronic esters with enantioenriched carbenoid species generated in situ by the addition of organolithium initiators to stereodefined α-chloroalkyl aryl sulfoxides was previously reported. The reaction of an organolithium with an α-chloroalkyl aryl sulfoxide ostensibly generates an α-chloroalkyllithium via sulfoxide-lithium exchange; however, the true nature...
This laboratory bioassay focused on lethal and sublethal effects of five
insecticides (chlorantraniliprole, cyantraniliprole, spinetoram, novaluron, and lambda-cyhalothrin) and two fungicide treatments (sulfur and a mixture of copper hydroxide and
mancozeb) on the predatory mired bug Deraeocoris brevis (Uhler) (Hemiptera: Miridae) using
second instars and adult males and females. Formulated...
This investigation examines The Jetsons’ vision of the future and tracks to what extent the content of the show is relevant to the modern era, both technologically and socially. Much of the dazzling technology in the show feels familiar, and most of it is either already available or is in...
Four key aspects of the relationship between predatory hoverflies and the aphid pest Brevicoryne brassicae L. on broccoli were investigated in the Willamette Valley, Oregon USA: 1) the relationship between aphid density and hoverfly oviposition, 2) the larval voracity of key hoverfly species, 3) the preferences of hoverflies and broccoli...
Although the literature is replete with techniques to assist
the researcher with the evaluation task, very few techniques
regarding an effective process for evaluating developmental
education programs have emerged. Those techniques that have
emerged have been criticized for not producing useful
results.
The central purpose of this research was to...
Vital rates and population connectivity are fundamental concepts in animal ecology and such information is critical for successful conservation planning. The Black-backed Woodpecker (Picoides arcticus) is a species of conservation concern because of its strong association with forests recently burned by high-severity wildfire. However, several recent studies have found that...
In Oregon perennial and annual grass seed cropping systems conservation management practices and their impacts on soil health and soil microbial community is not well understood. There is strong motivation to employ conservation tillage and other conservation practices to curb atmospheric carbon levels and improve soil health. However, the few...
Fungi and Actinobacteria are essential actors in global biogeochemical cycles of carbon and nutrients, and have both been recently appreciated for their roles in marine ecosystems. However, the diversity and distribution of these ubiquitous, but low-abundance microbes in deep-sea habitats remains poorly understood, particularly in chemosynthetic habitats such as methane...
