Certain detection of uncertain taxa: eDNA detection of a cryptic mountain sucker (Pantosteus jordani) in the Upper Missouri River, USA

Publications Posted on: September 30, 2020
A lineage of the Mountain Sucker species complex (Pantosteus jordani) exists as a genetically and morphologically distinct taxon restricted to the Missouri River basin. This species is thought to be declining throughout its range and is assumed to be extirpated from the southern portion of its distribution. We developed a quantitative PCR-based environmental DNA assay for P. jordani to help define and monitor its current range.

No fish left behind: Using eDNA sampling to inform fish eradication efforts

Science Spotlights Posted on: May 28, 2020
Environmental DNA methods are highly sensitive and accurate, making them ideal for detecting animals at low densities. However, this tool also come with its own unique set of challenges when applied to efforts to eradicate invasive species. This research explores the use of eDNA for evaluating invasive species eradication efforts in streams and offers best practices for incorporating eDNA methods into invasive species removal projects.

Parallel, targeted analysis of environmental samples via high-throughput quantitative PCR

Publications Posted on: May 10, 2020
When analyzing environmental samples for DNA from multiple taxa, researchers must usually decide between iterative analyses with single-taxon assays - which are reliable and sensitive, but also laborious to apply - and approaches such as metabarcoding that can simultaneously target multiple species, but which are less sensitive for detection across taxa.

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.
