Competing Interests

JH is an employee of Hemmera Envirochem Inc. JH was involved with the conceptualization of the overall research goals, identification of appropriate tailed frog survey sites, and water sample collection at these sites. Hemmera provided support for research materials, but did not play a role in the qPCR assay design, data collection and analysis, decision to publish, or preparation of the manuscript with the exception of critical review of the manuscript by JH. This does not alter our adherence to PLOS ONE policies on sharing data and materials. The specific roles of authors are articulated in the ‘author contributions’ section.
