Katy Klymus, PhD
Dr. Katy Klymus is a Research Biologist at the Columbia Environmental Research Center.
Since joining the USGS in 2016, Katy’s research focus has been on using genetic and genomic methods to inform wildlife species management. Currently she is studying environmental DNA methods, how they can be used to assess current levels of and changes in biodiversity, and development of standards for eDNA analyses. Additionally, she has a background in ecology, animal behavior and phylogenetics/ systematics.

Genomic variation in the genus Pimephales: raw sequence data and single-nucleotide polymorphisms
The fathead minnow (Pimephales promelas) is a key model of vertebrate toxicity. Standardized tests of toxicity in fathead minnow have been developed to support regulatory science, and much is known about the response of the species to various environmental pollutants. However, there is little data on genetic variation within the species, despite the potential influence of genetic...
Longnose darter (Percina nasuta) eDNA survey results from the St. Francis River, Missouri 2018
Data describe a designed environmental DNA (eDNA) survey for the detection of longnose darter (Percina nasuta) in field collected water samples. Parameters described include the limit of detection and limit of quantification of the assay; a list of freshwater fish species tissue samples that were used to test specificity of the assay; and field collected water samples that were tested to...
Metabarcoding data from freshwater mussel eDNA collected in Clinch River, Virginia 2017
Data from metabarcoding assays to detect a suite of mussel species using mitochondrial DNA regions of the cytochrome c oxidase subunit I (COI) and NADH dehydrogenase subunit (ND1) genes sequences.
Mucket eDNA detection in Wallen's Bend, Clinch river, Tennessee, September 2019
The data describe the technical performance of a designed qPCR assay for the detection of mucket (Actinonaias ligamentina) eDNA from field collected water samples. Parameters described include the sequences of the primers and probes used; the limit of detection and limit of quantification for the assay; a list of freshwater mussels species that were used to test specificity of the assay...

A comparison of eDNA and visual survey methods for detection of longnose darter Percina nasuta in Missouri
The longnose darter Percina nasuta is a rare and cryptic fish that recently disappeared from much of its historic range. We developed and used an environmental DNA (eDNA) assay for longnose darter paired with visual surveys to better determine the species’ range and compare detection probability between sampling approaches in an occupancy modeling framework. We detected longnose darter...

Editorial: Environmental DNA innovations for conservation
Environmental DNA (eDNA) analysis refers to the collection of bulk environmental samples such as water, sediment, or air, and studying the genetic remnants that organisms have shed into their environment to gain information about species presence.

Metabarcoding assays for the detection of freshwater mussels (Unionida) with environmental DNA
Freshwater mussels of the order Unionida are a widely distributed taxon that are important in maintaining freshwater ecosystems and are also highly imperiled throughout the world. Monitoring of mussel populations with environmental DNA (eDNA) is an attractive alternative to traditional methods because it is noninvasive and requires less labor and taxonomic knowledge from field personnel...

Development and testing of species-specific quantitative PCR assays for environmental DNA applications
New, non-invasive methods for detecting and monitoring species presence are being developed to aid in fisheries and wildlife conservation management. The use of environmental DNA (eDNA) samples for detecting macrobiota is one such group of methods that is rapidly becoming popular and being implemented in national management programs. Here we focus on the development of species-specific...

Reporting the limits of detection and quantification for environmental DNA assays
BackgroundEnvironmental DNA (eDNA) analysis is increasingly being used to detect the presence and relative abundance of rare species, especially invasive or imperiled aquatic species. The rapid progress in the eDNA field has resulted in numerous studies impacting conservation and management actions. However, standardization of eDNA methods and reporting across the field is yet to be...

Metabarcoding of environmental DNA samples to explore the use of uranium mine containment ponds as a water source for wildlife
Understanding how anthropogenic impacts on the landscape affect wildlife requires a knowledge of community assemblages. Species surveys are the first step in assessing community structure, and recent molecular applications such as metabarcoding and environmental DNA analyses have been proposed as an additional and complementary wildlife survey method. Here, we test eDNA metabarcoding as...
