Native bees are critically important organisms that support biodiversity and crop production via their pollination services. Wildfires in temperate conifer forests can increase bee abundance and flowering plant density due to increased light exposure, but little information is available regarding how wildfire severity influences provisioning to bee offspring, which is...
1. Early competitive environments can shape the development of offspring across taxa. For example, competition for food can have downstream effects on offspring phenotypes and fitness; however, little is known about how early competition influences the development of the hypothalamic-pituitary axis and its potential tradeoff with growth. Because baseline and...
Bee populations are declining around the globe, while the need for their pollination services is increasing with growing food demands by an expanding population. There is a need for innovative practices to increase pollination in agricultural environments without harming wild bee populations. However, the use of artificial visual attractants has...
Thermal transport properties of a material are often difficult to measure, especially for
thin films, but they are important for materials that have applications in modern devices,
such as nano-scale electronics, thermoelectrics, and thermally resistive coatings. In this
thesis, we describe an apparatus developed to measure the thermal conductivity of...
Organophosphate insecticides may produce sublethal, adverse effects on salmonid
growth, reproduction, maturation, swimming, and feeding. Chlorpyrifos, an
organophosphate insecticide, was detected by the Oregon Department of Environmental
Quality in the Hood River and tributaries during March 1999 at levels exceeding state
water quality standards in the range of 0.011-0.482 μg/L....
The West Fork Smith River, a 69 km2 watershed in the Coast Range of Oregon, is prone to short periods of very high water temperature in mid-summer due to a combination of human and natural influences. In the summers of 2003 and 2004 more than 400 juvenile coho salmon regularly...
In recent decades, the occurrence of large, high severity wildfires has increased substantially in many parts of the world, including the western United States. These fires have the potential to impact water quality, aquatic ecosystems, and downstream communities for many decades. As such, it is increasingly important to understand the...
Thomas Stearns Eliot’s 1922 modernist poem The Waste Land presents itself as an alternative to the decaying society Eliot found himself inhabiting. It begins as a personal means of pulling together one’s fragmented consciousness, but in doing so Eliot manages to present a solution to a world of selfishness—looking beyond...
