Repurposing environmental DNA samples to verify the distribution of Rocky Mountain tailed frogs in the Warm Springs Creek Basin, Montana

Publications Posted on: June 26, 2019
Rocky Mountain tailed frogs (Ascaphus montanus) were thought to exist exclusively in two tributaries of Warm Springs Creek watershed - Storm Lake Creek and Twin Lakes Creek, based on opportunistic observations of tailed frogs during fish sampling rather than formal basin-wide sampling for frogs.

The case for eDNA archiving: Case study in re-analyzing samples for the western pearlshell mussel

Science Spotlights Posted on: March 05, 2018
Effective conservation and management decisions for habitats require information about the distribution of multiple species but such data is expensive to obtain; this often limits data collection to just a few, high-profile species. Environmental DNA (eDNA) sampling can be more sensitive, and less expensive, than traditional sampling for aquatic species, and a single sample potentially contains DNA from all species present in a waterbody. Cost-savings accrue if eDNA collected for detecting a particular species can be repurposed to detect additional species. This study tested the feasibility of repurposing and re-analyzing already collected samples.
