The Role of Trees and Thermal Refugia in Greater Sage-Grouse Brood Habitat Selection

Creator:: Dungannon, Tyler D.
Abstract:: It is well documented that greater sage-grouse (Centrocercus urophasianus; hereafter sage-grouse) populations have been in decline throughout their range in the western United States. Currently, sage-grouse occupy approximately 56% of their historic distribution prior to European settlement. Numerous factors have been cited as potential causes for declining productivity and contraction...

The Interaction of Fire Refugia and Climate Refugia: A Case Study within California’s Diablo Mountain Range

Creator:: Turk, Douglas E.
Abstract:: As climate change contributes to larger and more severe wildfires in California, areas of fire refugia – considered unburned and low-severity burn patches – are playing an increasingly important role in sustaining ecosystem resilience, maintaining biodiversity, and supporting post-disturbance recovery. At the same time, climate refugia – which are areas...

Klamath Basin pilot project : coldwater refugia study and videography

Creator:: McIntosh, Bruce A., Li, Hiram W., Oregon State University. Department of Forest Science, and Oregon State University. Department of Fisheries and Wildlife
Abstract:: The purpose of this pilot program was to determine whether or not forward looking infrared (FLIR) videography could be used to develop thermal maps of the mainstem Klamath River to access habitat limitations due to high stream temperatures for fall chinook salmon (Oncorhynchus tshawytscha).

Seagrasses as Potential Chemical Refugia for Acidification-Sensitive Bivalves

Creator:: Smith, Stephanie Rae
Abstract:: As the effect of ocean acidification (OA) on marine calcifiers is better understood, a range of potential mitigative strategies have been proposed, many of which are plagued by concerns of scale and feasibility. One oft-cited option is to increase the biomass of photosynthetic organisms to remove CO₂ from the water...

Bryenton, A_Thesis.pdf

Creator:: Bryenton, Andrew G.
Abstract:: Alcoves in some river systems are cooler than the mainstem of the river and provide thermal refugia for aquatic species. An energy balance and sensitivity analysis on 3 alcoves in the Willamette River, Oregon indicate that alcove size and alcove flux determine the degree to which meteorological conditions affect the...

Large Downed Wood as Post-fire Refugia for Terrestrial Salamanders in Pacific Northwest Forests

Creator:: Stephens, Paige N.
Abstract:: Climate change, wildfire, timber harvest, and land conversion alter the availability of downed wood in forests of the western United States. Numerous taxa rely on downed wood for temperature and humidity refugia, and downed wood may play a key role in enabling the persistence of climate-sensitive, low-vagility species like terrestrial...

Marine Neritic and Epipelagic Community Dynamics: An Investigation of the 'Yin' and 'Yang', No-Analog, and Refugia from a Multi-species Perspective

Creator:: Barceló, Caren
Abstract:: Changes in ocean conditions influenced by climatic fluctuations have lead to changes in individual species distributions, which alter the diversity, communities and species interactions across marine ecosystems worldwide. Assessing the species composition and identifying regions and habitats that can safeguard the persistence of biota are critically important. In this dissertation,...

Heterogeneous thermal habitat for northeast Oregon stream fishes

Creator:: Ebersole, Joseph L.
Abstract:: Discrete coldwater patches within warm streams provide potential thermal refuge for coldwater fishes during periods of heat stress. This analysis focused on heterogeneity in stream water temperatures as influenced by local influx of cooler subsurface waters. Using field thermal probes and recording thermistors, we identified and characterized coldwater patches potentially...

Feasibility of Thermal Restoration by Groundwater Additions in the Middle Fork John Day

Creator:: Hale, Abigail E.
Abstract:: Survival of ecological systems pivot on critical moments. In the arid John Day Basin of Eastern Oregon, extensive restoration of the stream and floodplain focused on supporting salmon has been ongoing for the past 20 years, but recurring short periods of extreme temperature increase and low flows result in mortality...
