The accumulation of fuels in fire prone landscapes, and changing climatic conditions, have resulted in increasingly volatile fire behaviors. As a result, social and operational risk, management expenditures, and budgetary requirements for responsible agencies are increasing. The United States Forest Service (USFS) manages 193 million acres across the United States...
Early seral forests regenerating from stand-replacing disturbances provide unique habitat for many species in productive, temperate forest landscapes and contribute to supporting biodiversity. Population declines in some species associated with early seral forests have prompted concerns about the conservation of these habitats, particularly the characteristic structural and compositional complexity associated...
Molecular phylogenetic and chemical analyses, and morphological characterization of collections of North American Paraisaria specimens support the description of two new species and two new combinations for known species. P. cascadensis sp. nov. is a pathogen of Cyphoderris (Orthoptera) from the Pacific Northwest USA and P. pseudoheteropoda sp. nov. is...

Little is known about the fall and winter ecology of hibernating bats in western North America. Filling knowledge gaps for these populations has become more urgent with the westward spread of the white-nose syndrome, a disease that infects bats during hibernation. Due to the thermal requirements of the fungal pathogen...
The practice of modern silviculture on U.S. public lands has been stymied by a legacy of litigation and policy changes since the late 20th century. Forestry in the 1980s was focused on physical science strategies and failed to consider the social complexities of multi-use forest management. Emblematic of the challenges...
Beginning with the inception of American art history as a formal discipline in the 1940s, the dominant mode of interpreting nineteenth-century American landscape painting has been to view aspects of the landscape as symbols for grand cultural, religious, national, and moral narratives. While this method of interpretation highlights some key...
Since the discovery of penicillin in 1928, the fungal kingdom has remained a fertile source for the discovery of new, biologically active, natural products. Further, as natural products continue to be discovered from fungi, a deeper understanding of the critical role of specialized metabolism in fungal ecology is afforded. The...
Non-timber forest products (NTFPs) have an extensive history of harvest in the United States. The Pacific Northwest is well-reputed as a major source of floral greens for international markets. One NTFP in particular, beargrass (Xerophyllum tenax), has been repeatedly identified as a prominent, high-value species in the floral greens industry...
Mountain pine beetles (MPB) have killed millions of acres of forest throughout the Rocky Mountain ecoregion in the United States and Canada and climate change may be intensifying outbreaks. Climate change can change forest ecosystems and dynamics by increasing drought conditions and intensifying heat waves. Due to changing climate conditions,...
Anthropogenic land-cover change and climate change are the major drivers of the steep loss of avian biodiversity in past decades. Loss of avian biodiversity is predicted to result in the reduction of ecosystem services and ecological functions. Identifying avian population changes and the drivers of these trajectories is essential for...
Collaborative governance plays a significant role in forest management on public land in the Pacific Northwest. The method of governance offers the unique ability to engage a diverse range of stakeholders to reach consensus regarding forest management action. Evaluating the dynamics of the collaborative and its members is essential to...
Viral infections were investigated in American black bears (Ursus americanus) from Nevada and northern California with and without idiopathic encephalitis. Metagenomics analyses of tissue pools revealed novel viruses in the genera Circoviridae, Parvoviridae, Anelloviridae, Polyomaviridae, and Papillomaviridae. The circovirus and parvovirus were of particular interest due to their potential importance...
The Messenger magazine is published twice annually by Oregon State University Libraries and Press. This issue is devoted to the history of OSU Libraries and Press.
The Pisgah and Nantahala National Forests (PNNF) are located in the Southern Appalachian Mountains. A center of biological diversity, they are also within a few hours’ drive of much of the population of the United States. Therefore, there are many desires and objectives the public has for how these national...
Climate change is increasing the severity of pest and pathogen infestations affecting forests. Resulting shifts in disturbance patterns can have substantial ecological, social, and economic impacts on forested ecosystems and their dependent communities. Researchers are actively investigating methods to improve tree resistance to specific pests and pathogens and enhance forest...
Through researching CBOs across Washington, Oregon, Northern California, and British Columbia, it is evident that there are need gaps in the organizational capacity in CBOs and other environmental groups for outreach and communication support to collaborate. A dedicated online space where environmental organizations and other conservation-focused groups can share their...
Projected intensification of drought as a result of climate change may reduce the capacity of streams to rear fish, exacerbating the challenge of recovering ESA-listed salmon populations. Without management intervention, some stocks will likely go extinct as stream drying and fragmentation reduce juvenile survival to unsustainable levels. To offset drought-related...
This classification is an update of the 2004 classification of native vegetation of Oregon by Kagan, Christy, Murray and Titus. As before, this classification lists the native plant associations known to occur in Oregon, and includes both successional and climax vegetation types that were part of the presettlement landscape of...
As wolves return to their historic habitats both in Oregon and across the globe, emotions are running high between people either gladdened or disturbed by their homecoming. Prior to colonization, wolves occupied the entire Pacific Northwest alongside Indigenous peoples. However, European settlements that ultimately coalesced to form the state of...
The purpose of this dissertation was to examine the effects of war stressors and psychosocial factors on negative and positive mental health outcomes among Korean Vietnam War veterans. The sample consisted of 367 male veterans who completed a self-reported survey conducted in 2017 (Mage = 72, SD = 2.66, range...
Addiction is a word that represents a condition that, at best, causes minor disruptions to one’s life and, at worst, is lethal. The current definition was developed by 80 neuroscientists. It references substance use and other behaviors and includes food and sex. Addictions do not seem to be lessening but...
Conservation is, among other things, the expression of a relationship between humans and nonhuman nature. This relationship can be described empirically using the methods of social science, but it can also be prescribed in the form of philosophical arguments. Scholars in the field of environmental ethics have discussed and debated...
Zoos, aquariums and other free-choice/informal education settings offer the public opportunities to interact with live animals in exhibits through animal encounters and/or touch experiences designed to carry a conservation mission. Many of these institutions are accredited by the American Association of Zoos and Aquariums (AZA) and the World Association of...
The social sciences have the capacity to contribute to natural resource management through investigations of human dynamics associated with the environment. Sense of place (SOP), the formed relationships between an individual and the environment, has been considered a fundamental aspect of human well-being and can contribute to more holistic understanding...
In a subduction zone, the volcanic arc marks the location where magma, generated via flux melting in the mantle wedge, migrates through the crust and erupts. While the location of deep magma broadly defines the arc position, here we argue that crustal structures, identified in geophysical data from the Washington...
Wet meadow ecosystems are a useful natural laboratory in which to explore feedbacks between biogenic and geologic controls on valley bottom landforms. Characterized by flat valley floors flanked by higher-gradient hillslopes, these meadows are singular both in that they represent depositional features in what is primarily an erosional environment, and...
An increase in anthropogenic activities since the industrial revolution, primarily due to burning of fossil fuels and changes in land cover, has resulted in a steady increase in the global mean atmospheric CO2 concentrations. While there is unequivocal scientific evidence on global warming and its multidimensional impacts on natural and...
The Forest Service and the Bureau of Land Management propose to adopt coordinated ecosystem management direction for the lands they administer within the range of the northern spotted owl. This Supplemental Environmental Impact Statement (SETS) presents as alternatives the options, with slight modifications, developed by the Forest Ecosystem Management Assessment...
The settlement history of a remote area in the Coast Range of Oregon, from the 1870s to the 1930s, is examined through factors that may have influenced the success or failure, and length of residence of the homesteaders and later residents. Despite the rugged and isolated location, a small community...
