Interactions of Hydrological Processes and Riparian Zone Function During Seasonal Ceased Flow Regimes Within an Intermittent Stream Basin of the Oak Creek Watershed, Oregon, USA

Creator:: Colter, Nicholas R.
Abstract:: Riparian zone conservation is vital as species’ ability to adapt to a changing climate and pressure from land use is constantly tested. The unique microclimates of riparian zones offer cooler temperatures and resourceful habitats for aquatic and terrestrial organisms. This is essential during seasonal ceased flow regimes when water availability...

The morphology and ecology of Echinorhynchus lageniformis Ekbaum, 1938 (Acanthocephala)

Creator:: Barnes, James R.
Abstract:: The acanthocephalan Echinorhynchus lageniformis Ekbaum, 1938, is a common intestinal parasite of the starry flounder, Platichthys stellatus (Pallas), of Yaquina Bay, Lincoln Co., Oregon. Three hundred and sixty-one flounders were examined and 146 (40.5 percent) were found to harbor infections of E. lageniformis. Cystacanths of E. lageniformis were found encysted...

The life history of Neoechinorhynchus rutili (Mueller, 1780) and its development in the intermediate host (Acanthocephala ; Neoechinorhychidae)

Creator:: Merritt, Sheridan Vernon
Abstract:: The fish of Suttle Lake, Oregon, have been found to harbor an acanthocephalan parasite, which lives attached to the mucosa of the intestine. Between July 1961 and January 1963, several hundred of these fish were exarnined and nearly every one was infected with this parasite, which was identified as Neochinorhynchus...

Copper tolerance in four fungal species

Creator:: Grable, Carl Ivan
Abstract:: This study was initiated to determine the tolerance to copper of Aspergillus niger, Stemphylium sarcinaeforme, Monilinia fructicola and Fusarium oxysporum f. sp. lycopersici. Included were strains of the latter two fungi that were induced to tolerate relatively high levels of copper by continual culture on sublethal levels of the toxicant....

Understanding the Impact of Global Warming on Orographic Rain Shadows: Insights from a Pseudo-Global Warming Simulation over the Western United States

Creator:: Koszuta, Matthew
Abstract:: Some studies using regional climate models (RCMs) suggest a weakening of the climatological rain-shadow along the Cascade and Sierra Nevada mountains during the western US cool-season. To identify the possible mechanisms of rain-shadow weakening under warming, a new set of 30-year, high-resolution (6 km) pseudo-global warming (PGW) simulations were analyzed...

Understanding Drivers of Glacier Length Variability Over the Last Millennium

Creator:: Huston, Alan C.
Abstract:: Changes in glacier length reflect the integrated response to local fluctuations in temperature and precipitation, but when do such changes indicate forced climate change, and when do they indicate natural variability? In this study, we simulate the past ~1000 years of glacier length variability across the globe using the 3-stage...

Evaluating a Zonal-mean Hydrologic Model Against a Water Tag-enabled Global Simulation

Creator:: Mandovi, Andrew
Abstract:: The hydrologic cycle on Earth comprises the transitions among the solid, liquid, and gaseous phases of water. Understanding the hydrologic cycle is of course important for climate science, but also for agricultural, drinking water, and disaster preparedness purposes. Improvements in satellite observations and general circulation models (GCMs) have led to...

Systematically evaluating the developmental toxicity of nanomaterials using the zebrafish model

Creator:: Edwards, Sabrina R.
Abstract:: As engineered nanomaterials (ENM) become more common in consumer products, it is crucial to rapidly assess toxicity of unique ENM. Previous studies rarely focused on standardizing nanotoxicity testing, leading to inconsistent and irreproducible results. This study characterized a variety of ENM of different size, shape, core type, and surface charge...

Using environmental DNA to detect the invasive New Zealand mud snail (Potamopyrgus antipodarum) in freshwater

Creator:: Ponce, Jake J.
Abstract:: Environmental DNA (eDNA) detection of aquatic invasive species is at the forefront of aquatic conservation efforts because of decreased costs, increased response times, and increase of sensitivity for intercepting invasions with low density populations. Developments in eDNA technologies have improved detection probabilities for rare, indicator, and invasive species over the...
