Amphibian population declines and range constrictions are widespread but poorly understood. Effective conservation planning relies on accurate distribution data to develop a fundamental understanding of causal changes in species distributions. However, conventional detection methods for cryptic and elusive amphibians suffer from imperfect detection. Environmental DNA (eDNA) has emerged as an innovative and powerful conservation tool for detecting aquatic species presence; however comparative studies aimed at fully understanding eDNA detection probabilities are lacking. In this study, I used environmental DNA (eDNA) sampling methods and detailed historical records to identify drivers of extirpation and sampling method efficiency for an imperiled, long-lived giant …

Microbes inhabit virtually all surfaces of multicellular animal hosts, with microbial cells outnumbering the hosts’ own cells 10:1. Symbiont microbes, collectively referred to as the microbiome, can have profound impacts on the metabolism, development, behavior, and disease resistance of their multicellular hosts. Because the community structure of symbiont bacteria can influence host health, the characterization of amphibian microbiomes is becoming an increasingly important tool for future conservation in the face of global amphibian declines. Eastern hellbenders are good candidates for a microbiome study because they have seen substantial declines in recent decades and learning more about the environmental and physiological …
