Quantifying Carbon Production in Marine Ecosystems Using Expressions of Phytoplankton Physiology

Creator:: Penta, William Bryce
Abstract:: Phytoplankton initiate the marine carbon cycle by fixing carbon dioxide into biologically available compounds. These abundant single celled organisms mediate carbon flux from the atmosphere to the deep ocean and are the base of the marine food web, supplying new carbon to higher trophic levels. Phytoplankton are highly diverse and...

The activity and growth of a chlorophenol reductively dechlorinating soil culture in the presence of exogenous hydrogen

Creator:: Lotrario, Joseph Bryce
Abstract:: The addition of exogenously supplied hydrogen stimulates PCP reductive dechlorination and increases bacterial growth. While research focuses mainly on pure cultures, few exist capable of aryl reductive dechlorination, and few markers exist to identify reductively dechlorinating bacteria within mixed cultures. Furthermore, most active bioremediation projects stimulate mixed cultures of native...

Seasonal floodplain wetlands as fish habitat in Oregon and Washington

Creator:: Baker, Cynthia F.
Abstract:: To begin to understand freshwater seasonal floodplain fish communities in the context of human alteration of the physical system, species introductions and wetland restoration efforts, I studied fish assemblages in fifteen seasonal floodplain wetlands within four geographic regions (coastal, upper Columbia River estuary, Puget Sound and eastern Oregon/Washington) in the...

An evaluation of understory vegetation dynamics, ecosystem resilience and state and transition ecological theory in an eastern Oregon ponderosa pine forest

Creator:: Carr, Craig A.
Abstract:: Relatively recent increases in ponderosa pine abundance have effected unprecedented changes to ecosystem structure and function. Efforts to restore ponderosa pine systems are often focused on the manipulation of tree structure and the re-introduction of a more natural fire regime. Successful restoration should also incorporate understory components but information addressing...

Heterogeneous thermal habitat for northeast Oregon stream fishes

Creator:: Ebersole, Joseph L.
Abstract:: Discrete coldwater patches within warm streams provide potential thermal refuge for coldwater fishes during periods of heat stress. This analysis focused on heterogeneity in stream water temperatures as influenced by local influx of cooler subsurface waters. Using field thermal probes and recording thermistors, we identified and characterized coldwater patches potentially...

DNA binding and beyond : an investigation of proteins involved in PAH-induced carcinogesesis

Creator:: Hooven, Louisa Ada
Abstract:: Exposure to polycyclic aromatic hydrocarbons such as benzo[a]pyrene (B[a]P) has been determined to be a risk factor for various forms of human cancer. PAH DNA adducts have been shown to cause mutations, but carcinogenesis is also accompanied by alterations in gene expression. Inhibiting individual cytochrome P450s could clarify the interaction...

Influence of wetland landscape structure of shorebirds wintering in an agricultural valley

Creator:: Taft, Oriane Williams
Abstract:: Understanding how wetland birds use habitat is pivotal to developing successful and beneficial conservation strategies. Although it has been an ardent topic in forest research for some time, how species interact with the spatial patterning of habitat across a landscape (i.e., landscape structure) has been more or less neglected in...

Cation retention and solute transport related to porosity of pumiceous soils

Creator:: Doak, William Herman, 1941-
Abstract:: Previous studies of pumiceous soils in Oregon indicated that their physical and chemical properties were strongly related to the porous nature of the pumice matrix. Soils developed on air-fall pumice from the eruption of Mt. Mazama (Crater Lake, Oregon) had low thermal conductivities and low volumetric heat capacities. Values for...
