Stability of Biochar Under Storage Conditions and Evaluating its Potential as a Carbon Sequestration Tool in the United States

Creator:: Rovero, Matthew
Abstract:: Biochar has shown promise as a soil amendment for improvement of agricultural and forest productivity, remediation of heavy metals, and sequestration of carbon, but has not yet been adopted for widespread use in any of these applications. By assessing the production potential as a carbon sequestration tool, and the stability...

Context matters : A multi-scale assessment of riparian tree response to upslope density reduction

Creator:: Ruzicka, Kenneth J., 1982-
Abstract:: Forest management is rapidly undergoing a transformation from a discipline based on efficient commodity production to one for multiple uses, especially on federally managed land in the United States. This new management paradigm has challenged silviculturists to develop and adapt forest management techniques that can deal with increased demands. Using...

The Effects of Host and Pathogen Variation on Infection Dynamics in the Amphibian-Chytrid System

Creator:: Dang, Trang D.
Abstract:: This dissertation uses manipulative experiments to explore amphibian-Bd infection dynamics. Although there has been almost two decades research since the discovery of Bd, many questions still remain regarding what conditions mediate chytridiomycosis virulence. My research shows how certain host and pathogen factors can influence disease virulence. Identifying how host and...

Emerging infectious disease in lentic environments : the ecology and biogeography of the amphibian chytrid fungus Batrachochytrium dendrobatidis, with perspectives on water quality, limnology, and chemical contaminants

Creator:: Chestnut, Tara
Abstract:: Biodiversity losses in terrestrial, freshwater, and marine systems are accelerating at a global scale and the most threatened vertebrate taxa are those associated with freshwater habitats. The causes of biodiversity losses are often complex and include synergistic effects of natural and human-induced stressors, such as habitat loss and fragmentation, urbanization,...

Ontogenetic Shifts in Disease Response in Native and Invasive Anuran Species

Creator:: Urbina Gonzalez, Jenny Cecilia
Abstract:: This dissertation presents a different approach to understanding how amphibians are responding to disease through ontogeny. Although numerous efforts have been conducted to understand host responses to the fungus Batrachochytrium dendrobatidis (Bd), studies have been restricted to distinct developmental stages. This dissertation provides information on host response to Bd across...

Bioenergetic evaluation of diel vertical migration by bull trout

Creator:: Eckmann, Madeleine
Abstract:: I evaluated hypotheses related to growth as a driver of depth use and diel vertical migration by bull trout (Salvelinus confluentus) in a thermally stratified reservoir. I applied a bioenergetic model to evaluate growth of bull trout in relation to potential patterns of diel depth use by bull trout in...

The Behavioral Responses of Western Toad (Anaxyrus boreas) Larvae to Simultaneous Stressors

Creator:: Reynolds, Emily R.
Abstract:: Animals can be naturally exposed simultaneously to multiple stressors. These include habitat changes, contaminants, diseases, invasive species, parasitism, and predation. Exposure to various combinations of biotic and abiotic stressors may induce behavioral changes that affect the way an individual interacts within its environment.Like other groups of organisms, amphibians are exposed...

Basin-scale variation in the spatial pattern of fall movement of juvenile coho salmon in the West Fork Smith River, Oregon

Creator:: Hance, Dalton J.
Abstract:: from the summer dry season to the winter wet season. Such movement that connects summer and winter habitats may be particularly important for coho salmon, O. kisutch, because availability of overwintering habitat can limit freshwater survival for this species. Here, I describe basin-scale variability in the spatial pattern of fall...

Distribution of juvenile salmonids and stream habitat relative to 15-year-old debris-flow deposits in the Oregon Coast Range

Creator:: Kirkby, Kristen-Marie S.
Abstract:: Debris flows, common disturbances in many mountainous areas, initially scour or bury stream habitats; however, debris flows deliver vast amounts of wood, boulders, and gravel that may ultimately form complex stream habitat to potentially support a diverse salmonid assemblage. The materials deposited by debris flows would otherwise be inaccessible to...

The influence of sex, migration distance, and latitude on expression of anadromy in Oncorhynchus mykiss

Creator:: Ohms, Haley
Abstract:: The evolution and maintenance of multiple phenotypes within populations is an interesting evolutionary and ecological question, and is becoming increasingly important for the restoration and conservation of partially migratory species. In particular, why individuals adopt a particular phenotype has been the focus of numerous research efforts. In the partially migratory...
