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...

Cloning and characterization of GRASP, a novel retinoic acid-induced gene from P19 embryonal carcinoma cells

Creator:: Nevrivy, Daniel
Abstract:: Retinoic acid (RA) exerts important effects in the processes of vertebrate development, cellular growth and differentiation, and homeostasis. However, the mechanisms of action of RA in the control of cellular and developmental processes are incompletely understood, as the retinoid target genes have not been fully characterized. The goal of these...

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...

Early forest succession following clearcuts in western Oregon : patterns and abiotic controls

Creator:: Yang, Zhiqiang
Abstract:: Historical aerial photos were used to examine the early phase of forest succession after stand replacement disturbance, covering the Coast Ranges Province (CRP) and the western Cascades Province (WCP) of western Oregon. The study consisted of two components: characterizing the pattern of forest succession in western Oregon; analyzing the influence...

Environmental variability and system heterogeneity in terrestrial biogeochemical models

Creator:: Sierra, Carlos Alberto
Abstract:: Ecosystems are highly heterogeneous systems subjected to important levels of environmental variability; however, it is common in terrestrial biogeochemical models to assume homogeneous properties of the elements of the system or constant environmental conditions. For some processes, heterogeneity in these models is treated very simplistically, but there is not much...

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...

Functional relationships among songbirds, arthropods, and understory vegetation in Douglas-fir forests, western Oregon

Creator:: Hagar, Joan C.
Abstract:: Arthropods are important food resources for birds. Forest management activities can influence shrub-dwelling arthropods by affecting the structure and composition of understory shrub communities. Changes in abundance and species composition of arthropod communities in turn may influence the distribution and abundance of insectivorous birds. I examined relationships among bird abundance,...
