Species occurrence data from the aquatic eDNAtlas database

Datasets Posted on: December 30, 2020
The eDNA samples in the eDNAtlas database describe species occurrence locations and were collected by the U.S. Forest Service and numerous agencies that have partnered with the National Genomics Center for Wildlife and Fish Conservation (NGC) throughout the United States. This project began in 2015, but updates will include legacy data that were collected using the same protocol. The eDNAtlas database consists of three feature classes.

Summary of U.S. threatened and endangered species listings, 1976-2019

Datasets Posted on: December 30, 2020
These data document the summary of species, by taxonomic group, listed as threatened or endangered by the U.S. Fish & Wildlife Service from 1 July 1976 to 30 September 2019 for the United States.

Landscape resistance mediates native fish species distribution shifts and vulnerability to climate change in riverscapes

Publications Posted on: October 02, 2020
A broader understanding of how landscape resistance influences climate change vulnerability for many species is needed, as is an understanding of how barriers to dispersal may impact vulnerability. Freshwater biodiversity is at particular risk, but previous studies have focused on popular cold-water fishes (e.g., salmon, trout, and char) with relatively large body sizes and mobility.

This volume addresses the wildlife and fish of the grasslands in the Southwestern Region of the USDA Forest Service. Our intent is to provide information that will help resource specialists and decisionmakers manage wildlife populations within grassland ecosystems in the Southwestern United States. The information and analysis presented is at a Regional scale.

Using expressed behaviour of coho salmon (Oncorhynchus kisutch) to evaluate the vulnerability of upriver migrants under future hydrological regimes: Management implications and conservation planning

Publications Posted on: July 29, 2019
1. Globally, river systems have been extensively modified through alterations in riverscapes and flow regimes, reducing their capacity to absorb geophysical and environmental changes.

The eDNAtlas project: A national map of aquatic biodiversity

Science Spotlights Posted on: June 07, 2018
The National Genomics Center for Wildlife and Fish Conservation pioneered development of eDNA sampling of aquatic environments at their laboratory in Missoula, MT. The Center has partnered with dozens of National Forests, as well as other state, federal, tribal, and private natural resource organizations to assist in the collection and processing of eDNA samples. Thousands of eDNA samples are collected annually and constitute a rapidly growing biodiversity archive that provides precise information about native and non-native species distributions, temporal trends in those distributions, and the efficacy of species and habitat restoration and conservation efforts. eDNA sampling provides a low-cost & sensitive method for determining which species occur in water bodies. Rapid adoption of eDNA sampling by many natural resource agencies led to an exponential increase in data and the need for an open-access database. The website and open-access database were launched in June 2018 with approximately 6,000 samples and is updated semi-annually with newly processed samples.

The importance of sound methodology in environmental DNA sampling

Publications Posted on: May 21, 2018
Environmental DNA (eDNA) sampling - which enables inferences of species’ presence from genetic material in the environment - is a powerful tool for sampling rare fishes. Numerous studies have demonstrated that eDNA sampling generally provides greater probabilities of detection than traditional techniques (e.g., Thomsen et al. 2012; McKelvey et al. 2016; Valentini et al. 2016; Wilcox et al. 2016). In contrast, Ulibarri et al.

Global warming of salmon and trout rivers in the northwestern U.S.: Road to ruin or path through purgatory?

FS News Posted on: May 10, 2018
What will the future hold for western river systems and the cold-water species that depend on them? To answer this question, scientists at the USDA Forest Service Rocky Mountain Research Station compiled temperature records from nearly 400 monitoring sites along large rivers in the northwestern United States.

NorWeST modeled summer stream temperature scenarios for the western U.S.

Datasets Posted on: March 15, 2018
NorWeST summer stream temperature scenarios were developed for all rivers and streams in the western U.S. from the > 20,000 stream sites in the NorWeST database where mean August stream temperatures were recorded.

NorWeST stream temperature data summaries for the western U.S.

Datasets Posted on: March 15, 2018
NorWeST is an interagency stream temperature database and model for the western United States containing data from over 20,000 unique stream locations. Temperature observations were solicited from state, federal, tribal, private, and municipal resource organizations and processed using a custom cleaning script developed by Gwynne Chandler. Summaries of daily, weekly, and monthly means, minima, and maxima are provided for observation years.
