Using genetics to distinguish limber from whitebark pine

Publications Posted on: October 01, 2020
The northern Rocky Mountains, the Great Basin, and the central Sierra Nevada are regions of North America where limber pine (Pinus flexilis James) and whitebark pine (Pinus albicaulis Engelm.) live in sympatry or close proximity. For those needing to distinguish between these two pine species in these areas of western North America, seed cones are the best visual identification aid.

Exploiting the winter trophic relationship between weasels (Mustela spp.) and their microtine prey as a survey method for weasels in meadow ecosystems

Publications Posted on: July 02, 2020
Weasels can be important components of grassland and meadow communities where they influence the dynamics of small mammal populations which, in turn, can be keystone species in these communities. We evaluate a method for detecting and identifying two species of North American mustelines (i.e., Mustela frenata and M. erminea) in mountain meadow systems.

Red fox ancestry and connectivity assessments reveal minimal fur farm introgression in Greater Yellowstone Ecosystem

Publications Posted on: April 09, 2019
Rocky Mountain red foxes Vulpes vulpes macroura potentially encounter other red fox Vulpes vulpes lineages at lower elevations, which may include nonindigenous red foxes derived from fur farms. Introgression from nonindigenous red foxes could have negative evolutionary consequences for the rare Rocky Mountain red fox subspecies.

The aquatic eDNAtlas project

Projects Posted on: February 08, 2018
The website provides: 1) A large list of supporting science behind eDNA sampling. 2) The recommended field protocol for eDNA sampling and the equipment loan program administered by the NGC. 3) A systematically-spaced sampling grid for all flowing waters of the U.S. in a downloadable format that includes unique database identifiers and geographic coordinates for all sampling sites. Available for download in an Geodatabase or available by ArcGIS Online map. This sampling grid can be used to determine your field collection sites to contribute. 4) The lab results of eDNA sampling at those sites where project partners have agreed to share data.

Marine mammal subspecies in the age of genetics: Introductory remarks from the Associate Editor and Editor-in-Chief of Marine Mammal Science

Publications Posted on: July 19, 2017
Almost every conservation genetics and evolutionary biology textbook has a section questioning: "What is a species or subspecies?" It has been one of the most discussed, nearly unanswerable questions in all of biology. At issue is how to logically divide a variable that is generally continuous, with some occasional discrete breaks.

Managing invasive annual brome grasses and altered fire regimes

Science Spotlights Posted on: August 19, 2016
Invasive annual brome grasses are resulting in altered fire regimes and conversion of native arid and semi-arid ecosystems in the western United States to annual grass dominance. The problem is particularly acute in sagebrush shrublands where cheatgrass (Bromus tectorum) has resulted in annual grass fire cycles that are placing numerous native species such as greater sage-grouse at risk and threating ecosystem services such as livestock forage, hunting and recreation, and even clean air and water. This 15-chapter book examines the environmental impacts, invasiveness, environmental controls, and management alternatives for invasive annual brome-grasses.

Great Basin Native Plant Project: 2015 Progress Report

Publications Posted on: June 21, 2016
The Interagency Native Plant Materials Development Program outlined in the 2002 United States Department of Agriculture (USDA) and United States Department of Interior (USDI) Report to Congress encouraged use of native plant materials for rangeland rehabilitation and restoration where feasible.

Silviculture in special places: proceedings of the 2003 National Silviculture Workshop

Publications Posted on: May 12, 2016
This proceedings presents a compilation of 20 manuscripts and five posters summarizing results of research studies and management projects conducted throughout the United States in areas with special natural resource values.

Genetic diversity and genecology of squirreltail (Elymus elymoides)

Projects Posted on: February 09, 2016
Squirreltail (Elymus elymoides) can rapidly colonize disturbed sites, is relatively fire-tolerant, and is a potential competitor with medusahead (Taeniatherum caput-medusae) and cheatgrass (Bromus tectorum). Determining the extent to which adaptive genetic variation is related to climatic variation is needed to ensure that the proper germplasm is chosen for revegetation and restoration. This study provides (1) seed zones and seed transfer guidelines for developing adapted plant materials of squirreltail for revegetation and restoration in the Great Basin and adjacent areas and (2) guidelines for conservation of germplasm within the National Plant Germplasm System.

Genetic diversity of prairie junegrass (Koeleria macrantha)

Projects Posted on: February 09, 2016
Good drought tolerance and fibrous roots make prairie junegrass (Koeleria macrantha) beneficial for revegetation and erosion control on mined lands, over septic systems, in construction areas, on burned sites, and in other disturbed areas. There is a need for greater genetic knowledge of this species to ensure adapted populations are used for restoration and revegetation projects. This study provides (1) seed zones and seed transfer guidelines for developing adapted plant materials of prairie junegrass for revegetation and restoration in the Great Basin and adjacent areas and (2) guidelines for conservation of germplasm within the National Plant Germplasm System.
