Abstract

Research focused on understanding the parameters leading to massive mortality of amphibian populations in some regions during certain time frames is important for the development of conservation and management strategies. Sampling for Bd up to this point has largely been opportunistic and haphazard, so little information exists on the true presence/absence of the disease across the U.S., and thus, how to most appropriately sample for it. In addition, more information is needed concerning the relationship of Bd prevalence with environmental and climate variables. The ability to detect Bd with a standardized protocol is necessary for the management of amphibian populations and determining how environmental and temporal factors affect detection probabilities is crucial. Obtaining information on the distribution, prevalence, and detectability of Bd in the Midwestern U.S. is a critical first step in assessing the threat this pathogen may pose to amphibian assemblages and directing conservation actions towards affected species. The objectives of this research are to 1) Estimate the prevalence of Bd in Midwestern U.S. cricket frog populations; 2) Determine how environmental and temporal factors affect estimated prevalences.
