Biodiversity Responses in Early Seral Forests of the Klamath-Siskiyou: Comparisons with Birds, Bees, and Ground Beetles among Post-fire, Salvage Logging, and Intensive Forest Management Environments

Creator:: Frank, Graham S.
Abstract:: 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...

Drug Discovery and Chemical Ecology Investigations of Specialized Metabolism in Tolypocladium and Paraisaria

Creator:: Tehan, Richard M.
Abstract:: 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...

An examination of climate and land-use change as drivers of population dynamics in breeding birds

Creator:: Kim, Hankyu
Abstract:: 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...

The Effects of War Stressors and Psychosocial Factors on Mental Health among Korean Vietnam War Veterans

Creator:: Lee, Hyunyup
Abstract:: 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...

Discursive and Psychological Processes in Project MATCH Treatment Manuals and 12-Step Program Literature

Creator:: O'Hara, Margaret A.
Abstract:: 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...

On Morality, Psychology, and Conservation: An Interdisciplinary Appraisal of Ethics in Context

Creator:: Batavia, Chelsea K.
Abstract:: 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...

Are Families Talking about Conservation at Live Animal Exhibits? Analyzing Family and Professional Conservation Discourse

Creator:: Rowe, Susan Roberta M.
Abstract:: 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...

Construction, Degradation, and Restoration of Wet Meadow Ecosystems in Semi-arid Landscapes, Northern Great Basin, USA

Creator:: Nash, Caroline S.
Abstract:: 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...

Ecosystem Photosynthesis and Forest-Atmosphere Interactions Inferred from Carbonyl Sulfide

Creator:: Rastogi, Bharat
Abstract:: 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...

Evaluation of mix ingredients on the performance of rubber-modified asphalt mixtures

Creator:: Takallou, Hossein B.
Abstract:: Rubber-modified asphalt pavements have been used in Sweden and the United States since the 1970's. In these applications ground recycled tire particles (0.25 inch minus) are added to a gap-graded aggregate and then mixed with hot asphalt cement. The benefits of adding rubber to the mix include increased skid resistance...
