Forest Successional and Disturbance Dynamics in the Southern Blue Mountains of Eastern Oregon

Creator:: Johnston, James D.
Abstract:: The application of modern land management practices beginning at the turn of the 20th century is widely believed to have dramatically transformed forest landscapes of the inland Pacific Northwest. Restoring historical conditions to make forests resilient to future climate and disturbance regimes is a major goal of federal forest managers....

Serologic survey of infectious disease agents in black bears (Ursus americanus) of California, Oregon, and Washington

Creator:: Mortenson, Jack A.
Abstract:: The causes of natural mortality and disease in free ranging black bears, Ursus americanus, in California, Oregon, and Washington are poorly known. Life history components, such as scavenging and overlapping habitat with many species of carnivores, potentially expose bears to a wide range of infectious disease agents. To date, no...

Unraveling the Diagenetic Cycling and Sequestration of Rare Earth Elements (REEs) in Marine Sediments to Understand REE Accumulation in Ancient Shales

Creator:: Yang, Jon
Abstract:: The rare earth elements (REEs) have been established as powerful tracers for a range of physiochemical processes occurring in the natural environment. They also hold significant economic importance as many technological advancements are reliant upon the REEs for their unique magnetic, luminescent, and electrochemical characteristics. In sedimentary settings, understanding the...

An Assessment of Black-backed Woodpecker (Picoides arcticus) Vital Rates in Green and Burned Forests within a Pyrodiverse Landscape Mosaic

Creator:: Kerstens, Mark E.
Abstract:: Vital rates and population connectivity are fundamental concepts in animal ecology and such information is critical for successful conservation planning. The Black-backed Woodpecker (Picoides arcticus) is a species of conservation concern because of its strong association with forests recently burned by high-severity wildfire. However, several recent studies have found that...

An evaluation of factors influencing the management of Otiorhynchus sulcatus (F.) (Coleoptera: Curculionidae)

Creator:: Kepler, Ryan M.
Abstract:: The black vine weevil (BVW), Otiorhynchus sulcatus (F.) (Coleoptera: Curculionidae) is a persistent pest of nursery operations in the United States, feeding on over 140 species of plants. The goals of this research were to 1) assess the behavioral response of BVW to a commonly employed insecticide bifenthrin (Talstar 0.2G®)...

Offshore controls on nearshore circulation

Creator:: Long, Joseph W.
Abstract:: The rip current field resulting from the transformation of surface gravity waves over offshore submarine canyons is studied. Employing a wave transformation model and a wave-induced circulation model over observed bathymetry we find that rip current circulation cells exist with alongshore spacing of O(1OOm) even though the nearshore bathymetry displayed...

Sites of Memory : Black Women's Geographies, #SayHerName, and Black Hair Politics

Creator:: Adkins, Daryl
Abstract:: According to Katherine McKittrick, black women’s geographies reveal and confront geographies of domination that have been erased or considered unworthy of analysis. This thesis positions #SayHerName protests and natural kink/coiled hair within a black women’s geographic analysis suggesting that both body and hair politics provide historical and contemporary geographic clues...

Defining micro-habitat relationships for juvenile black rockfish, Sebastes melanops

Creator:: Mann, Marion E.
Abstract:: The functioning of marine habitats needs to be understood in the context of the ecological relationships and associations between organisms and the physical and biogenic environment they inhabit. Thus, it becomes important to explore and define habitat features which contribute to these relationships and which are important in the life...

Community Ecology of Foliar Fungi and Oomycetes of Pseudotsuga menziesii on the Pacific Northwest Coast

Creator:: Gonen, Lilah
Abstract:: Pseudotsuga menziesii var. menziesii (coast Douglas-fir) is a tree of ecological, economic, and cultural value in its native North American Pacific Northwest (PNW) distribution. P. menziesii is host to a variety of well-documented endophytic foliar microorganisms, including the fungus Nothophaeocryptopus gaeumannii, the causal agent of Swiss needle cast (SNC), and...
