A chronosequence of wood decomposition in the boreal forests of Russia

Creator:: Yatskov, Mikhail A.
Abstract:: Coarse woody debris (CWD) decomposition in the Russian boreal forests of the southern taiga zone was studied at four sites located near St. Petersburg in Northwestern Russia, Krasnoyarsk in Eastern Siberia, lrkutsk in the Baikal region, and Khabarovsk in the Russian Far East. This study was part of a broader...

Associations of forest floor vertebrates with coarse woody debris in managed forests, western Oregon Cascades

Creator:: Butts, Sally R.
Abstract:: Forest floor vertebrate species presence and abundance may be influenced by the volume and cover of coarse woody debris (CWD) in managed forests. I studied macro- and microhabitat associations of vertebrate species in 18 closed-canopy stands ranging in CWD volume from 14 to 859 m3/ha. Pitfall traps were used to...

Carbon storage in a Pacific Northwest conifer forest ecosystem : a chronosequence approach

Creator:: Janisch, Jack E.
Abstract:: As concern over global warming intensifies, sequestration and storage of atmospheric CO2 has become an important scientific and policy issue. Confusion persists, however, over interpretation of forest carbon (C) source-sink dynamics, in part because conclusions drawn depend on temporal and spatial scales of analysis (e.g. day-week scale vs. successional-scale), type...

Comparison of Octopus dofleini hemocyanin paralogues and evidence for recent divergence

Creator:: van Olden, Erin K.
Abstract:: Presented here is an in depth comparison of the Octopus dofleini hemocyanin paralogues, designated A and G. The protein sequences coded by these genes are each comprised of seven oxygen-binding units, or functional units (FU-a to FU-g). Each FU is approximately 400 amino acids in length and a linker region...

Design of a microstructured liquid-liquid separator utilizing a capillary pressure gradient

Creator:: Zoebelein, Conor M.
Abstract:: Continuous liquid-liquid two-phase separation is needed in microfluidic devices. Due to the small characteristic lengths of microreactors, phenomena such as mass transport via molecular diffusion occur within seconds. Typically, discrete slugs of an extract are created within microchannels for high specific interfacial area to achieve intensified mass transfer. A challenge...

Evaluating the rates of nitrate removal for a nitrate containing, low organic carbon wastewater interacting with carbon-containing solid substrates

Creator:: Hart, Jeffrey L.
Abstract:: The primary objective of this study was to evaluate the rates of nitrate removal for a nitrate containing, low organic carbon wastewater interacting with four different carbon-containing solid substrates (alder woodchips, corn silage, manure and woodchip biochar). Batch systems were tested for nitrate removal, and systems with a combination of...

Fungal diversity within decomposing woody conifer roots in Oregon

Creator:: Vandegrift, V. Eleanor
Abstract:: Previous studies have indicated that roots from five tree species (Picea sitchensis, Tsuga heterophylla, Pseudotsuga menziesii, Pinus ponderosa, and Pinus contorta) decompose at different rates across an environmental gradient in Oregon. Measurements of wood chemistry from each tree species as well as moisture and temperature from each location do not...

Hydraulic characterization and modeling of the Talking Water Garden wetland for evaluation of nitrogen removal

Creator:: Huang, Tao
Abstract:: The purpose of this research is to hydraulically characterize an engineered wetland in Albany, Oregon. The wetland receives treated wastewater from both Albany Millersburg Water Reclamation Facility (AMWRF) and ATI Wah Chang. AMWRF's water is municipal waste water. ATI Wah Chang's water comes from its nearby metal processing plant. The...

Inter-annual variability of net primary productivity across multiple spatial scales in the western Oregon Cascades : methods of estimation and examination of spatial coherence

Creator:: Woolley, Travis J.
Abstract:: Quantifying and modeling processes involved in the global carbon cycle is important to evaluate the temporal and spatial variability of these processes and understand the effect of this variability on future response to changing climate and land use patterns. Biomass accumulation and Net Primary Productivity (NPP) are large components of...

Interactions between grizzly bears and hikers in Glacier National Park, Montana

Creator:: Jope, Katherine Louise McArthur
Abstract:: Behavior of grizzly bears (Ursus arctos) toward people was studied by examining hikers' reports of grizzly bear observations and by intensively observing grizzlies in an area of Glacier National Park that was heavily used by day-hikers. Of concern were the apparent habituation of grizzly bears to people in the study...
