Redd site selection and spawning habitat use by fall chinook salmon

Creator:: Geist, David R.
Abstract:: The spawning habitat associated with fall chinook salmon (Oncorhynchus tshawytscha) redd clusters was investigated in the Hanford Reach of the Columbia River. A conceptual spawning habitat model is proposed that describes how geomorphic features of river channels create hydraulic processes, including hyporheic flows, that influence where salmon spawn in unconstrained...

Valuing nonmarket goods and services : a test for bias in the iterated referendum-contingent valuation format

Creator:: McLeod, Donald M.
Abstract:: Contingent valuation has been used to elicit values for changes in the quantity and quality of nonmarket amenities. Yet hypothetically trading dollars for environmental improvements is not a familiar activity for most survey respondents. A variety of response effects associated with survey collected data can potentially lead to biased contingent...

Identification of a mechanism underlying heritable subfertility in roosters homozygous for the rose comb allele

Creator:: McLean, Derek J.
Abstract:: The overall objective of this research was to define the cellular basis underlying heritable subfertility in roosters homozygous for the rose comb allele (R/R). Fertilization in the hen is preceded by the ascension of motile sperm through the vagina and sperm sequestration within sperm storage tubules (SST). The objective of...

Critical windows of transplacental carcinogenesis : identifying efficacious approaches to chemoprevention with dietary phytochemicals

Creator:: Castro, David J.
Abstract:: Polycyclic aromatic hydrocarbons (PAHs) are a re-emerging class of environmental pollutants. The persistent nature of these highly toxic compounds along with their ubiquity in the environment creates an unavoidable route of exposure. The developing fetus and neonate are a particularly susceptible population due to their incomplete complement of xenobiotic metabolizing...

An Empirical Analysis of Climate and Risk on Rural Productive Lands

Creator:: Finer, Cassie R.
Abstract:: Efficient and effective climate policies require cost estimates supported by empirical analysis at multiple spatial scales. Fine-scale spatial analysis of climate impacts for rural land markets represents a gap in the current climate change economics literature. In this dissertation I estimate relationships between climate, risk and parcel-level land values for...

The effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin on T cell activation

Creator:: Shepherd, David M.
Abstract:: The immune system has been identified as a very sensitive target for the toxic effects of 2,3,7,S-tetrachlorodibenzo-p-dioxin (TCDD). Exposure to TCDD has been shown to disrupt the generation of both cell-mediated and humoral T cell-dependent immunity in laboratory animals; however, the mechanism remains unknown. In this dissertation, the hypothesis is...
