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,...

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...

Ecological aspects of kin discriminating behavior with implications of functional value

Creator:: Hokit, D. Grant
Abstract:: To assess the context dependence of kin discriminating behavior, I examined kin-biased aggregation behavior in tadpoles of R. cascadae in different ecological conditions. I manipulated food distribution, predator presence, thermal heterogeneity, and relatedness in a multifactorial mesocosm experiment. All four factors interacted to influence tadpole dispersion. My results suggest that...

Host-pathogen dynamics in a changing environment : susceptibility of amphibians to an emerging infectious disease

Creator:: Searle, Catherine L.
Abstract:: Infectious diseases are a growing concern for both humans and wildlife. The negative effects of infectious disease have been exemplified by the recent global amphibian population declines associated with disease outbreaks. Although multiple pathogens and factors play a role in these declines, the aquatic fungal pathogen, Batrachochytrium dendrobatidis (Bd), has...

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...

All hosts are not created equal : variation in amphibian responses to an emerging fungal pathogen and why it matters

Creator:: Gervasi, Stephanie S.
Abstract:: Emerging infectious diseases are increasing globally and are a threat to human, wildlife, and ecosystem health. The emerging fungal pathogen, Batrachochytrium dendrobatidis (Bd), or amphibian chytrid fungus, is associated with worldwide amphibian population declines and extinctions. Bd has been found on every continent where amphibians exist and has been documented...

The Role of Emerging Pathogens in Amphibian Population Declines : Experimental Evidence

Creator:: Hambalek, Natalie M.
Abstract:: Rapid rates of biodiversity loss have supported the notion that Earth is experiencing a sixth major extinction event. The causes of worldwide biodiversity loss are multifaceted and context dependent. One of the most prominent groups experiencing population declines and extinctions are amphibians. Several pathogens and their associated diseases are especially...

Disentangling the Biotic and Abiotic Drivers of the Amphibian Disease Chytridiomycosis

Creator:: Bradley, Paul W.
Abstract:: The ongoing worldwide loss of biodiversity has been described as a "biodiversity crisis," "the Anthropocene defaunation," and alternatively "an extinction spasm." More recently, many scientists have come to the conclusion that we are witnesses to Earth's sixth major mass extinction event, which has the potential to fundamentally alter basic ecological...

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...

Environmental influences on host-pathogen dynamics of the amphibian chytrid fungus

Creator:: Buck, Julia C.
Abstract:: The causes of the global biodiversity crisis are varied and complex. Anthropogenic threats may act in isolation, or interact additively or synergistically with each other or with natural stressors to affect sensitive taxa. The recent emergence of many infectious diseases in wildlife has brought attention to the role of disease...
