Whether media plays a contributory or a conduit role in the policy process has been a salient focus among policy scholars. If media plays a contributory role in the policy process, it not only shares similar policy core beliefs with advocacy coalitions, but also drafts and disseminates stories including policy...
This study examines stream channel erosion processes in a small urbanizing watershed influenced by deposits of the Columbia Basin catastrophic floods: Kelley Creek, a 12-km² tributary of Johnson Creek, located just east of Portland, Oregon. Information on landscape history, stream channels, and sediment dynamics was compiled. The effects of future...
This PhD dissertation describes and evaluates a geographical analysis of candidate areas for siting nuclear plants utilizing a wet cooling tower in the Columbia River Basin (CRB). It focuses on the analysis of water availability for cooling and how it may be limited by climate change effects on river streamflow....
This study examined water scarcity and vulnerability in Quintana Roo, along the northern Caribbean coast of Mexico where rapid growth of tourism in the past 40 years has limited the ability of rural and urban communities to obtain safe, reliable, and equitable access to water services and critical water infrastructure...
This study examined patterns and controls on 35-years of forest succession following logging in the 236 ha South Umpqua Experimental Forest within the Umpqua National Forest in southwestern Oregon. Prior to logging, the overstory in all three watersheds (~50% cover) was composed of Douglas-fir (30-40% cover), grand fir (2 to...
Spatial variation in the diet of the northern spotted owl (Strix occidentalis caurina) influences owl home ranges, and understanding this relationship will aid managers in forest management prescriptions that influence spotted owl recovery. This study describes the spatial variation in owl diet based on 4183 prey collected at 114 owl...
Although the Pacific Northwest has the least proportion of non-native plant species in relation to other regions of North America, exotic species continue to spread into mountainous areas, including the Cascade Range. In a forested landscape, road networks can act as corridors for exotic plant dispersal and establishment, helping species...

The objective of this study was to compile, validate, and map minimum and maximum mean monthly temperature and temperature ranges for periods of 10 to 14 months between July 2009 and June 2012, measured using 16 to 182 sensors distributed over the HJ Andrews Forest, a mountain landscape of 64...
The relationship between mothers and daughters has been shown to be
generally positive and strong throughout the life cycle. The relationship may
become strained, however, as mothers become dependent due to deteriorating
health or chronic health conditions. It has long been recognized in both the
gerontological and intergenerational literatures that...
Increasing population and land use decisions have had a negative effect on the aquatic ecosystems in the Willamette River Basin. One result is elevated temperatures in many of the Basin’s streams, which adversely affect the fish that live in these streams. There are several regulatory mechanisms in place to improve...
