A phenological examination of terrestrial invertebrate abundance at H. J. Andrews Experimental Forest, Oregon

Creator:: Mackereth, Kailan F.
Abstract:: Abstract Understanding the effects of climate change on forest ecosystems requires exploration of the relationships of different components of the system, such as the response of biota to local hydrology, temperature, precipitation, and elevation. The Long-term Ecological Research Program at the H. J. Andrews Experimental Forest, located in the Western...

Soil surface CO2 efflux across the climatic gradient of the Oregon Transect for Terrestrial Ecological Research (OTTER)

Creator:: Martin, Mark A.
Abstract:: Soil CO2 efflux is a major contributor of CO2 to the atmosphere. The rate that CO2 is respired out of the soil is called the soil flux (Fs). Many variables alter Fs. These variables differ drastically in the variety of ecosystems found on the earth. It is important to understand...

Chromosome visualization in a temperate anemone, Anthopleura elegantissima

Creator:: Shaffer, Lucy J.
Abstract:: Anthopleura elegantissima (Cnidaria: Anthozoa) is an emerging model organism for studying the endosymbiotic relationship between dinoflagellate (genus Symbiodinium) and the cnidarian host. To be developed as a model organism, more genetic resources, like integrated genome and linkage map, are needed. An important validation for developing genomic resources is chromosome number....

The Gut Microbiome Drives Benzo[a]pyrene's Impact on Zebrafish Behavioral Development

Creator:: Sieler, Michael J.
Abstract:: Benzo[a]pyrene (B[a]P) is a common environmental pollutant produced from the incomplete combustion of organic matter, such as fossil fuel emissions. In vertebrates, B[a]P exposure is associated with hyperactivity, though the underlying mechanisms driving this effect are undescribed. Mounting evidence indicates that the gut microbiome, which is the diverse community of...

Native wildlife species (Pseudacris regilla) utilizing invasive-dominated habitat in a highly disturbed ecosystem

Creator:: Epperly, Haley K.
Abstract:: The Pacific Treefrog (Pseudacris regilla) is commonly encountered throughout the Pacific Northwest and can be an indicator for ecosystem health. At each life stage P. regilla utilizes a different habitat and therefore it is important to understand habitat use at all life stages to properly manage the ecosystem, however, few...

The toxicogenetic effects of a chitosan based hemostatic control patch in rat models

Creator:: Colburn, Andrew J.
Abstract:: Chitosan based hemorrhage control dressings provide effective external hemorrhage control while having few side effects. Known residual contaminants present in chitosan formulations include endotoxins and proteins known to stimulate gene expression in the liver. This study investigated gene expression in the liver using rat bio-compatibility models to gain knowledge regarding...

Whole system perspective : Steelhead, Onchorhynchus mykiss, glutathione s-transferase as a biomarker of chlorpyrifos exposure

Creator:: Pecore, Rachael G.
Abstract:: Organophosphate insecticides may produce sublethal, adverse effects on salmonid growth, reproduction, maturation, swimming, and feeding. Chlorpyrifos, an organophosphate insecticide, was detected by the Oregon Department of Environmental Quality in the Hood River and tributaries during March 1999 at levels exceeding state water quality standards in the range of 0.011-0.482 μg/L....

Carbon isotopes show snowpack acts as a valuable moisture subsidy to mountain forests in the Oregon Cascades

Creator:: Ratcliff, Christopher J.
Abstract:: This study examines climatological influences, particularly that of snowpack, on tree growth and stable carbon isotope discrimination (Δ¹³C) from ~1980 to 2013 at two sites located in the upper reaches of the McKenzie River watershed of the Oregon Cascade Mountains. We tested the use of Δ¹³C values from latewood, corroborated...
