Management opportunities and research priorities for Great Plains grasslands

Publications Posted on: September 26, 2019
The Great Plains Grassland Summit: Challenges and Opportunities from North to South was held April 10-11, 2018 in Denver, Colorado to provide syntheses of information about key grassland topics of interest in the Great Plains; networking and learning channels for managers, researchers, and stakeholders; and working sessions for sharing ideas about challenges and future research and management opportunities.

Does burn severity affect plant community diversity and composition in mixed conifer forests of the United States Intermountain West one decade post fire?

Publications Posted on: September 14, 2019
Background: Wildfire is an important ecological process in mixed conifer forests of the Intermountain West region of the USA. However, researchers and managers are concerned because climate warming has led to increased fire activity in recent decades.

Field demonstration of a semiochemical treatment that enhances Diorhabda carinulata biological control of Tamarix spp.

Publications Posted on: September 13, 2019
The northern tamarisk beetle Diorhabda carinulata (Desbrochers) was approved for release in the United States for classical biological control of a complex of invasive saltcedar species and their hybrids (Tamarix spp.). An aggregation pheromone used by D. carinulata to locate conspecifics is fundamental to colonization and reproductive success.

Where the desert meets the river: Investigating southwestern riparian ecosystems

Science Spotlights Posted on: August 23, 2019
Rivers and streams of the American Southwest have been heavily altered by human activity, resulting in significant changes to disturbance regimes. Riparian vegetation in aridland floodplain systems is critically important as foraging, migrating, and breeding habitat to birds and other animal species. To conserve riparian ecosystems and organisms, understanding how plants and animals are affected by disturbance processes and multiple stressors is critical.

Back from the brink: Framework to sustain resilience to species at risk

Science Spotlights Posted on: August 14, 2019
The Regeneration for Resilience (R4R) framework provides a decision structure to prioritize limited resources and utilize seedling planting and natural regeneration management to offer the best likelihood of success in positioning stands and landscapes to support resilience self-sustaining tree populations that are threatened by invasive pests. Effective management of forest regeneration dynamics can increase forest resilience and adaptive capacity to mitigate impacts of invasive species.

Using our understanding of resilience to disturbance and resistance to invasive annual grasses to target management actions in the sagebrush biome

Projects Posted on: July 30, 2019
The concepts of ecological resilience and resistance to invasive annual grasses have been used to develop an understanding of sagebrush ecosystem response to disturbances like wildfire and management actions to reduce fuels and restore native ecosystems. A multi-scale framework that uses these concepts to prioritize areas for conservation and restoration at landscape scales and to determine effective management strategies at local scales has been developed by Chambers and her colleagues. Regional SageSTEP (Sagebrush Treatment Evaluation Project) data coupled with west-wide AIM (Assessment, Inventory and Monitoring) data provide a unique opportunity to refine the predictors of resilience and resistance and extend the existing multi-scale framework effort.

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.

Invasive Species Science Update (No. 11)

Publications Posted on: June 10, 2019
In this issue, we cover new research ranging from using chili powder to improve native plant restoration, searching for a link between exotic white pine blister rust and mountain pine beetle resistance in limber pine, identifying how melting arctic sea ice could open new pathways for invasive species introductions, and research into a relatively newly established biocontrol agent for rush skeletonweed.

Fine-scale environmental DNA sampling reveals climate-mediated interactions between native and invasive trout species

Publications Posted on: November 29, 2018
It is widely recognized that biotic interactions may act as important mediators of species responses to climate change. However, collecting the abiotic and biotic covariates at the resolution and extent needed to reveal these interactions from species distribution models is often prohibitively expensive and labor-intensive.
