This paper explores the connection between the agricultural use of neonicotinoid pesticides and the decline of wild bumblebee populations across the United States.
There is an urgent need to lower the concentration of sulfur in diesel fuels. Growing concern over environmental effects caused by burning sulfur-containing diesel has led the world to higher standards in fuel refinement. Because of these lower standards, many techniques have been researched to remove sulfur containing compounds or...
This thesis presents a decentralized communication planning algorithm for cooperative terrain-based navigation (dec-TBN) with autonomous underwater vehicles. The proposed algorithm uses forward simulation to approximate the value of communicating at each time step. The simulations are used to build a directed acyclic graph that can be searched to provide a...
Oregon's only remaining non-reservoir population of adfluvial bull trout (Salvelinus confluentus) is found in Odell Lake, in the headwaters of the Deschutes River. The population size is unknown, but appears to be quite small. Limited spawning and rearing habitats, combined with the effects of introduced species and other anthropogenic changes...
The increasing human demands on natural resources, in combination with uncertainties about ecosystem dynamics due to global change, has led the scientific community to conclude that new approaches in understanding of ecological systems are needed to tackle environmental issues in an efficient manner. One development that has received more attention...
Vibrio vulnificus and Vibrio parahaemolyticus are ubiquitous in the marine–estuarine environment, but the
magnitude of human non-ingestion exposure to these waterborne pathogens is largely unknown. We evaluated
the magnitude of dermal exposure to V. vulnificus and V. parahaemolyticus among swimmers recreating in Vibrio-populated
waters by conducting swim studies at four...

Many endemic species, particularly those on
remote islands, have been driven to extinction or near extinction
by anthropogenic influences. The short-tailed albatross
Phoebastria albatrus once numbered in the millions
but was thought to be extinct by the mid 20th century.
Albatrosses, of the family Diomedeidae, are among the most
threatened...

This article describes the motivation, design, and progress of the Journal of Open Source Software (JOSS). JOSS is a free and open-access journal that publishes articles describing research software. It has the dual goals of improving the quality of the software submitted and providing a mechanism for research software developers...
Oregon Biography Index is intended to serve primarily as a starting point in locating biographies of Oregonians. We have indexed 47 historical volumes which are either entirely devoted to biographies or have large self-contained biographical sections. The profiles in the books vary widely in accuracy and detail. Birth dates of...
