Development and Infectious Disease in Hosts with Complex Life Cycles

Creator:: Searle, Catherine L., Xie, Gisselle Yang, and Blaustein, Andrew R.
Abstract:: Metamorphosis is often characterized by profound changes in morphology and physiology that can affect the dynamics of species interactions. For example, the interaction between a pathogen and its host may differ depending on the life stage of the host or pathogen. One pathogen that infects hosts with complex life cycles...

Predation by zooplankton on Batrachochytrium dendrobatidis: Biological control of the deadly amphibian chytrid fungus?

Creator:: Buck, Julia C., Truong, Lisa, and Blaustein, Andrew R.
Abstract:: Batrachochytrium dendrobatidis (hereafter Batrachochytrium), a fungal pathogen of amphibians, causes the disease chytridiomycosis which is responsible for unprecedented population declines and extinctions globally. Host defenses against chytridiomycosis include cutaneous symbiotic bacteria and anti-microbial peptides, and proposed treatment measures include use of fungicides and bioaugmentation. Efforts to eradicate the fungus from...

Host Identity Matters in the Amphibian-Batrachochytrium dendrobatidis System: Fine-Scale Patterns of Variation in Responses to a Multi-Host Pathogen

Creator:: Gervasi, Stephanie, Gondhalekar, Carmen, Olson, Deanna H., and Blaustein, Andrew R.
Abstract:: Species composition within ecological assemblages can drive disease dynamics including pathogen invasion, spread, and persistence. In multi-host pathogen systems, interspecific variation in responses to infection creates important context dependency when predicting the outcome of disease. Here, we examine the responses of three sympatric host species to a single fungal pathogen,...

Host species composition influences infection severity among amphibians in the absence of spillover transmission

Creator:: Han, Barbara A., Kerby, Jacob L., Searle, Catherine L., Storfer, Andrew, and Blaustein, Andrew R.
Abstract:: Wildlife epidemiological outcomes can depend strongly on the composition of an ecological community, particularly when multiple host species are affected by the same pathogen. However, the relationship between host species richness and disease risk can vary with community context and with the degree of spillover transmission that occurs among co-occurring...

Ultraviolet Radiation Influences Perch Selection by a Neotropical Poison-Dart Frog

Creator:: Kats, Lee B., Bucciarelli, Gary M., Schlais, David E., Blaustein, Andrew R., and Han, Barbara A.
Abstract:: Ambient ultraviolet-B radiation can harm amphibian eggs, larvae and adults. However, some amphibians avoid UV-B radiation when given the opportunity. The strawberry poison dart frog, Oophaga pumilio, is diurnal and males vocalize throughout the day in light gaps under forest canopies that expose them to solar radiation. Previous studies have...

Heterogeneous Occupancy and Density Estimates of the Pathogenic Fungus Batrachochytrium dendrobatidis in Waters of North America

Creator:: Chestnut, Tara, Anderson, Chauncey, Popa, Radu, Blaustein, Andrew R., Voytek, Mary, Olson, Deanna H., and Kirshtein, Julie
Abstract:: Biodiversity losses are occurring worldwide due to a combination of stressors. For example, by one estimate, 40% of amphibian species are vulnerable to extinction, and disease is one threat to amphibian populations. The emerging infectious disease chytridiomycosis, caused by the aquatic fungus Batrachochytrium dendrobatidis (Bd), is a contributor to amphibian...

Differences in sensitivity to the fungal pathogen Batrachochytrium dendrobatidis among amphibian populations

Creator:: Bradley, Paul W., Gervasi, Stephanie S., Hua, Jessica, Cothran, Rickey, D., Relyea, Rick A., Olson, Deanna H., and Blaustein, Andrew R.
Abstract:: Contributing to the worldwide biodiversity crisis are emerging infectious diseases, which can lead to extirpations and extinctions of hosts. For example, the infectious fungal pathogen Batrachochytrium dendrobatidis (Bd) is associated with worldwide amphibian population declines and extinctions. Sensitivity to Bd varies with species, season, and life stage. However, there is...

Shifty salamanders: transient trophic polymorphism and cannibalism within natural populations of larval ambystomatid salamanders

Creator:: Jefferson, Dale M., Ferrari, Maud C. O., Mathis, Alicia, Hobson, Keith A., Britzke, Eric R., Crane, Adam L., Blaustein, Andrew R., and Chivers, Douglas P.
Abstract:: INTRODUCTION: Many species of ambystomatid salamanders are dependent upon highly variable temporary wetlands for larval development. High larval densities may prompt the expression of a distinct head morphology that may facilitate cannibalism. However, few studies have characterized structural cannibalism within natural populations of larval salamanders. In this study we used...

Effects of Pesticide Mixtures on Host-Pathogen Dynamics of the Amphibian Chytrid Fungus

Creator:: Buck, Julia C., Hua, Jessica, Brogan, William R. III, Dang, Trang D., Urbina, Jenny, Blaustein, Andrew R., Bendis, Randall J., Stoler, Aaron B., and Relyea, Rick A.
Abstract:: Anthropogenic and natural stressors often interact to affect organisms. Amphibian populations are undergoing unprecedented declines and extinctions with pesticides and emerging infectious diseases implicated as causal factors. Although these factors often co-occur, their effects on amphibians are usually examined in isolation. We hypothesized that exposure of larval and metamorphic amphibians...

Larval exposure to predator cues alters immune function and response to a fungal pathogen in post-metamorphic wood frogs

Creator:: Groner, Maya L., Buck, Julia C., Gervasi, Stephanie, Blaustein, Andrew R., Reinert, Laura K., Rollins-Smith, Louise A., Bier, Mark E., Hempel, John, and Relyea, Rick A.
Abstract:: For the past several decades, amphibian populations have been decreasing around the globe at an unprecedented rate. Batrachochytrium dendrobatidis (Bd), the fungal pathogen that causes chytridiomycosis in amphibians, is contributing to amphibian declines. Natural and anthropogenic environmental factors are hypothesized to contribute to these declines by reducing the immunocompetence of...
