Oregon's estuaries are important ecosystems for scientific study. Consequently, knowledge of what research has been conducted helps us identify benchmarks and plan new projects. A comprehensive bibliography of published research, technical reports, local documents, and data sets is one means of recording this knowledge. For these reasons, the Guin Library...
Relieving phosphorus loading is a key management tool for controlling Lake Erie eutrophication. During the
1960s and 1970s, increased phosphorus inputs degraded water quality and reduced central basin hypolimnetic
oxygen levels which, in turn, eliminated thermal habitat vital to cold-water organisms and contributed to the
extirpation of important benthic macroinvertebrate...
The red-band trout is native to many small, isolated streams in southeastern Oregon. A study of the red-band population of Three-
mile Creek and Reservoir was conducted from August 1973 to June 1975. Data were collected concerning population size, age composition,
growth, biomass, recruitment, fecundity, and habitat. During the spring...
Climate Change in the Northwest: Implications for Our Landscapes, Waters, and Communities is a report aimed at assessing the state of knowledge about key climate impacts and consequences to various sectors and communities in the Northwest United States. This report draws on two recent state climate assessments in Washington in...
Food webs consist of a combination of bottom-up (resource-driven) and top-down (predator-driven) effects. The strength of these effects depends on the context in which they occur. I investigated food web (trophic) relationships between wolf (Canis lupus) predation, elk (Cervus elaphus) herbivory, aspen (Populus tremuloides Michaux) recruitment, and fire. The study...
Intracellular dNTP pool sizes are highly asymmetric, with dGTP usually comprising 5 to 10% of the sum of the dNTP pools. The work presented in this dissertation addresses the question of whether the underrepresentation of dGTP is related to its potential to be oxidized by reactive oxygen species. 8-oxo-guanine is...
We compiled existing data and information to characterize the condition and trends in high priority natural resources in Ebey’s Landing National Historical Reserve (EBLA, or "the Reserve"). We identified 29 indicators to evaluate seven major resource concerns. For each indicator we attempted to define reference conditions to which we could...
In the present study, five breeds of ewes and their lambs were
utilized. The breeds used were: Border Cheviot, Dorset Horn, Columbia,
Suffolk and Willamette. In all, 31 ewes and 42 lambs were involved.
The blood constituents which were determined for the ewes and
lambs were: acid and alkaline phosphatase,...
Consistent with its charge under Oregon House Bill 3543, the Oregon Climate Change Research Institute (OCCRI) conducts a biennial assessment of the state of climate change science, including biological, physical, and social science, as it relates to Oregon and the likely effects of climate change on Oregon. This fifth Oregon...
This study provides an empirical test of the Bockstael-McConnell
(1980) household production function (HPF) framework for evaluating wildlife recreation. This is perhaps the first study in which
both taste and technology parameters have been estimated with a
theoretical model specification. The results suggest that for
steelhead sport fishing in Oregon,...
