Using environmental DNA sampling to monitor the invasion of nonnative Esox lucius (northern pike) in the Columbia River basin, USA

Publications Posted on: July 10, 2019
Aquatic invasive species are recognized as a global threat to conservation of native species and a cost to society. To develop effective suppression and monitoring programs for invasive species, fisheries managers require accurate, affordable, and efficient tools for invasive species detection. In the U.S.

Understanding mountain big sagebrush seed production variability

Science Spotlights Posted on: November 15, 2017
Historically, the sagebrush biome was the most widespread non-forest vegetation type in temperate North America. Compared with historic conditions, current sagebrush ecosystems are reduced in extent, fragmented, degraded, and face multiple threats (Welch 2005), including altered fire regimes (USDI 2015).

Seed production estimation for mountain big sagebrush (Artemisia tridentata ssp. vaseyana)

Publications Posted on: September 25, 2017
Seed production is an essential component of postdisturbance recovery for mountain big sagebrush (Artemisia tridentata Nutt. ssp vaseyana [Rydb] Beetle; MBS). We tested a method for rapid estimation of MBS seed production using measurements of inflorescence morphology.

Can rapid assessment protocols be used to judge sediment impairment in gravel-bed streams? A commentary

Publications Posted on: June 08, 2015
Land management agencies commonly use rapid assessments to evaluate the impairment of gravel-bed streams by sediment inputs from anthropogenic sources. We question whether rapid assessment can be used to reliably judge sediment impairment at a site or in a region.
