Molecular systematic studies in the genus Ribes (Grossulariaceae)

Creator:: Messinger, Wes
Abstract:: Infrageneric classification in Ribes has previously relied on a few, often conflicting, morphological markers, such as spines, glands, and inflorescence morphology. Suggestions that hybridization drives the evolution of the genus have not been tested using phylogenetic methods. To assess the validity of infrageneric classifications and the importance of hybridization to...

Institutional capacity building through land and water stewardship integration - an analysis of source water protection in Corvallis, Oregon

Creator:: Odom, Olivia
Abstract:: Globally, access to safe, reliable drinking water sources is a major challenge of this generation. Protected sources of drinking water provide communities with a sustainable, vital resource, yet many public water suppliers lack legal authority over their source water protection (SWP) area, especially in surface water systems.

The influence of aging dams and geography on the distribution of dam removals in the United States

Creator:: Ashley, Sara
Abstract:: Over 470 dams have been removed in the United States, and a significant increase in dam removals has occurred since the early 1990s. The aging of dams is often cited as the primary factor influencing removals; as dams surpass their functional life span, safety hazards, economic costs, and environmental concerns...

Returning grain to the lower-Willamette Valley : Prospects and barriers for local food security

Creator:: Malone, Chevelle P.
Abstract:: A critical link is missing between food production and food consumption. This gap can be overcome by encouraging the production of staple food crops and emphasizing regional and community consumption of locally produced food. In order to re-establish local food security in the Willamette Valley, it is imperative that essential...

A topography of dams in China : impacts to agriculture, labor, and migration

Creator:: Foster-Moore, Eric
Abstract:: Dams are often promoted as a tool to reduce poverty and spur economic development. Dam construction worldwide, and particularly in China, which has built nearly half the world's large dams since 1949, remains contentious due to the potential for negative environmental and socioeconomic impacts. Despite numerous case studies, there is...

Assessing the Current State of Transboundary Cooperation in the International Columbia River Basin

Creator:: Timboe, Ingrid A.
Abstract:: The Columbia River Treaty (CRT) is often used as an example of how treaties can work to normalize, regulate, and improve the cooperative management of shared water resources between basin countries. Few would argue that, in its limited mandate to regulate hydropower generation and flood risk management for downstream communities,...
