Contractile function and calpain activity in mouse skeletal muscle during hypoxia

Creator:: Hu, Hui
Abstract:: Calcium activated proteases, or calpains, are activated in cardiac muscles under conditions of ischemia/reperfusion and hypoxia. Their activity in skeletal muscle under similar conditions is poorly understood. We tested the hypothesis that hypoxia elevates calpain-mediated proteolysis in isolated glycolytic (extensor digitorum longus, EDL) and oxidative (soleus, SOL) mouse muscles studied...

Spatial and temporal variations in respiration rates and hypoxia on the Oregon shelf

Creator:: Wolf, Megan J.
Abstract:: Inner shelf hypoxia has occurred along the Oregon coast between the latitudes 44ºN and 45ºN since 2002 with increasing duration and intensity, posing a threat to marine life. The objective of this research was to determine whether variation in respiration rate explains spatial and temporal variation in hypoxia. Dissolved oxygen...

Effects of Hypoxia on Survival and Growth of Barnacle Larvae Off the Oregon Coast

Creator:: Amstutz, Amanda C.
Abstract:: In recent years off the United States Oregon coast severe hypoxic events have resulted in areas of mass vertebrate and invertebrate species mortality known as dead zones. Creation of dead zones and alteration of community species composition in response to inner shelf hypoxic conditions have been observed annually from 2002...

Relationship Between Winter Downwelling Conditions and Summer Hypoxia Severity Along the Oregon Coast

Creator:: Walters, Helen Marie
Abstract:: Hypoxia is a naturally occurring phenomenon that happens seasonally off the Oregon coast. As a consequence, there has been a great deal of research focused around analyzing the strength and duration of the hypoxic event during the summer season. This paper, however, takes an innovative approach by looking at the...

Regulation of mouse ribonucleotide reductase by allosteric effector-substrate interplay and hypoxia

Creator:: Chimploy, Korakod
Abstract:: In order to maintain genetic stability in eukaryotes, tight regulation of the relative sizes of deoxyribonucleoside triphosphate (dNTP) levels inside the cell is essential for optimal fidelity of DNA replication. Ribonucleotide reductase (RNR) is the enzyme responsible for proportional production of DNA precursors. Studies on regulation of this enzyme, the...

Distribution and abundance of juvenile demersal fishes in relation to summer hypoxia and other environmental variables in coastal Oregon, USA

Creator:: Sobocinski, Kathryn L., Ciannelli, Lorenzo, Wakefield, W. Waldo, Yergey, Matthew E., and Johnson-Colegrove, Angela
Abstract:: The juvenile demersal fish assemblage along the Pacific Northwest coast has received little attention relative to adult life history stages since pioneering work in the 1970s. Increasing severity of hypoxia along the Oregon coast in recent years has prompted investigations into the response of biota in this region. We used...

Foraging behavior of the Pacific harbor seal (Phoca vitulina richardii) in the Pacific Northwest and potential impacts of coastal hypoxia on foraging efficiency

Creator:: Steingass, Sheanna M.
Abstract:: In the last decade, the California Current Large Marine Ecosystem has experienced a trend of increased severity of upwelling-driven coastal hypoxia. This thesis strove to examine the potential upper trophic level impacts of moderate and severe hypoxia in the CCLME. Initially I conducted a literature review of Pacific harbor seal...

An investigation of the distribution and abundance of ichthyoplankton and juvenile benthic fishes in relation to nearshore hypoxia within the Northern California Current system

Creator:: Johnson, Angela M.
Abstract:: Nearshore hypoxia within the Northern California Current (NCC) system is a seasonal phenomenon caused by coastal upwelling and occurs mainly during late-summer and early fall. The effects of low oxygen levels on fish and invertebrate communities, particularly during early-life history stages, however, are poorly known for this area. I investigated...

Quantifying Sensitivity and Adaptive Capacity of Shellfish in the Northern California Current Ecosystem to Increasing Prevalence of Ocean Acidification and Hypoxia

Creator:: Gossner, Hannah M.
Abstract:: The severity of carbonate chemistry changes from ocean acidification is predicted to increase greatly in the coming decades, with serious consequences for marine species- especially those reliant on calcium carbonate for structure and function (Fabry et al. 2008). The Northern California Current Ecosystem off the coast of US West Coast...

Fishing for Hypoxia: Exploring Coastal Oxygen Dynamics and Predictability of Low Oxygen Episodes through a Partnership with the Oregon Dungeness Crab Fishing Fleet

Creator:: Stoltz, Linus O.
Abstract:: Coastal hypoxia, or low oxygen episodes pose a threat to marine resources in the Pacific Northwest. Previous research into nearshore oxygen dynamics have linked coastal upwelling to this seasonally occurring phenomenon, however the manifestation of hypoxic waters over coastal fishing grounds was not well understood. Through a partnership with Dungeness...
