Effects of Diversity on Emerging Infectious Diseases of Amphibians

Creator:: Snyder, Paul W.
Abstract:: Species declines and extinctions have been recorded across taxa as evidence of an ongoing global biodiversity crisis. Amphibians are at the forefront of these declines with nearly one third of amphibian species estimated to be at risk of extinction. While many factors contribute to population declines and extinctions, the role...

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...

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...

The Role of Algal Cellular Physiology on the Onset and Maintenance of a Model Cnidarian-Algal Symbiosis

Creator:: Maruyama, Shumpei
Abstract:: Coral reefs form vast ecosystems in tropical oceans that are hotspots for biodiversity and are economically valuable. The ecological success of coral reefs is made possible by the symbiotic relationship between corals and dinoflagellate algae from the family Symbiodiniaceae. In this symbiosis, the algae are found within host gastrodermal cells...

Amphibian Population Declines and Extinctions: Disease in Amphibian Communities with Cascading Effects in Freshwater Communities

Creator:: Harjoe, Carmen C.
Abstract:: Earth is experiencing unprecedented biodiversity loss. Amphibians are at the forefront of this biodiversity loss, with species declines estimated to be more severe than those of birds and mammals. Amphibian population declines and extinctions are driven by a number of factors including climate change, habitat destruction, contaminants and disease but...

Emergent Properties of Animal Social Networks: Five Stories in Five Systems

Creator:: Devan-Song, E. Anne
Abstract:: Animals aggregate and interact in nonuniform and nonrandom patterns, which lead to group level characteristics that have important evolutionary and ecological consequences. Network analysis provides a useful conceptual framework for linking animal interactions at all scales from dyads to communities, to populations and ecosystems. Despite exciting theoretical and applied advances...

Genomic Resource Development and Studies of Thermal Tolerance in Symbiotic Cnidarians

Creator:: Elder, Holland L.
Abstract:: Reef building corals are the foundation of an entire ecosystem, but they are threatened primarily by rising ocean temperatures due to climate change. Corals depend on a thermally sensitive symbiosis with intracellular dinoflagellates. As oceans warm, this symbiosis is disrupted and results in coral mortality, declining populations and degraded reefs....

Relationship between parasite load and diet quality in two desert bighorn sheep metapopulations in southern California

Creator:: Gibson, Sarah
Abstract:: The increased severity of unseasonal drought conditions in the American Southwest have resulted in herbivorous species, like the desert bighorn sheep (Ovis canadensis nelsoni), receiving lower quality forage in their diet at less reliable frequency. The Mojave Desert and the Peninsular Mountain ranges also contain large variations in elevation, which...

Modifications to Rearing Environments as a Method for Reducing Domestication Selection in Hatchery-reared Steelhead (Oncorhynchus mykiss)

Creator:: Obley, Miriam
Abstract:: Since the decline of salmonid populations in the Pacific Northwest, supplementation programs have become frequently implemented by hatcheries as a way to protect and conserve wild stock. However, hatchery-reared fish have lower fitness than wild fish which is likely due to adaptation to the hatchery environment, i.e., domestication selection. Fish...

Seismic survey vessel noise pollution in nearshore Southern Oregon : spatial and temporal analysis of demersal fish movements

Creator:: Borland, Lauren K.
Abstract:: Sound is a crucial aspect of the underwater environment for fishes – various species use sound to communicate, identify predators, navigate, and many other activities needed for survival in their habitat. Disruptions and disturbances in the natural soundscape can have important impacts on all these activities and are likely to...
