An evaluation of a water, sanitation, and hygiene (WASH) program for rural communities in northern Afghanistan

Creator:: Costello, Denise H.
Abstract:: The Water, Sanitation and Hygiene (WASH) sector of international development works to increase access to sustainable, safe water and improved sanitation. Currently, at least 780 million people live without clean drinking water and 2.5 billion without access to improved sanitation (UNICEF & World Health Organization, 2012). Lack of access to...

Impacts of Ocean Acidification on Coralline Algae : From Species to Community Consequences

Creator:: Shen, Chenchen
Abstract:: Oceanic uptake of rising anthropogenic CO₂ emissions has caused the emergence of ocean acidification as a major threat to marine ecosystems worldwide. Along eastern boundary current systems, seawater is naturally acidified due to coastal upwelling of low pH seawater from depth. Compounded by ocean acidification, upwelling regions are expected to...

Historic Survival Rates and Cause-Specific Mortality for Columbian Black-Tailed Deer in Southwest Oregon

Creator:: Groot, Kevyn A.
Abstract:: In contrast with other Odocoileus species, Columbian black-tailed deer (Odocoileus hemionus columbianus) population dynamics are not well understood throughout the species’ range. Concerns over apparent long-term population declines have prompted efforts to fill basic knowledge gaps including estimates of vital rates (fecundity, recruitment and survival) and cause-specific mortality. The Oregon...

Evaluation of Compartmentalized Aquifers in the Walla Walla Subbasin of Oregon Using Isotopic and Geochemical Tracers

Creator:: van Stolk, Courtney A.
Abstract:: The Walla Walla Subbasin (WWSB) in Oregon is underlain by formations of the extensive Columbia River Basalt Group (CRBG) which have been deformed by post-Miocene folding and faulting. Extensive irrigation with groundwater from these basalt groups, as well as sedimentary aquifers and surface water diversions from the Walla Walla River,...

Movement and space use by the green hermit (Phaethornis guy) in a fragmented landscape in Costa Rica

Creator:: Volpe, Noelia L.
Abstract:: Human activities have altered Earth’s ecosystems. Most biomes have experienced a 20-50% conversion to human use. Loss of habitat has obvious effects on the persistence of species. Fragmentation, however, may also negatively affect biodiversity for those species that exhibit behavioral responses to changes in habitat configuration. Such behavioral changes include...

Mathematical models of decision processes for dispersing animals

Creator:: Brugger, Max F.
Abstract:: Each chapter in this expository paper considers a mathematical model of an aspect of animal behavior, and how it aﬀects the patterns of movement across and within a landscape. These models are all directly or indirectly related to questions in either Behavioral Ecology or Landscape Ecology, or both. I ﬁrst...

Transformation of Western Hemlock Tree Crowns by Dwarf Mistletoe

Creator:: Calkins, Stephen J.
Abstract:: Hemlock dwarf mistletoe (Arceuthobium tsugense subsp. tsugense) is an arboreal, hemiparasitic plant that principally parasitizes western hemlock (Tsuga heterophylla). Hemlock dwarf mistletoe exerts a profound influence on infected trees that can drastically change the structure of the tree crown due to reduced growth, top dieback, branch deformation and death, resulting...

Resilience and adaptability of transboundary rivers : the principle of equitable distribution of benefits and the institutional capacity of the Nile Basin

Creator:: Iyob, Biniam
Abstract:: Biophysical, socioeconomic and geopolitical pressures from population growth and economic development are leading to an increase in tensions regarding the sharing of water within transboundary basins. Transboundary basins are surface rivers and groundwater resources that are shared among sovereign nations and autonomous regions. This dissertation focuses on surface water in...

Sediment reservoir dynamics on steepland valley floors : influence of network structure and effects of inherited ages

Creator:: Frueh, Walter Terry
Abstract:: Sediment deposit ages inferred from radiocarbon dating of stream bank material were used to estimate residence times of valley-floor deposits in headwater valleys of the Oregon Coast Range, USA. Inherited ages of radiocarbon-dated material, i.e., time between carbon fixation in wood and its incorporation in a sediment deposit, can result...

Plant community dynamics in remnant and restored Willamette Valley wetland prairies

Creator:: Schwindt, Rachel A.
Abstract:: Invasion by exotic species can pose a major challenge for developing native plant communities in wetland restoration projects. Often native plant communities do not develop as anticipated in restored wetlands due to colonization by exotic species that dominate the native plant community. Despite the time and expense to restore wetlands,...
