Consequences of inoculation with native arbuscular mycorrhizal fungi for root colonization and survival of Artemisia tridentata ssp. wyomingensis seedlings after transplanting

Publications Posted on: October 02, 2019
In arid environments, the propagule density of arbuscular mycorrhizal fungi (AMF) may limit the extent of the plant–AMF symbiosis. Inoculation of seedlings withAMF could alleviate this problem, but the success of this practice largely depends on the ability of the inoculum to multiply and colonize the growing root system after transplanting. These phenomena were investigated in Artemisia tridentata ssp.

Quantifying ecological integrity of terrestrial systems to inform management of multiple-use public lands in the United States

Publications Posted on: April 16, 2019
The concept of ecological integrity has been applied widely to management of aquatic systems, but still is considered by many to be too vague and difficult to quantify to be useful for managing terrestrial systems, particularly across broad areas.

Effects of climate change on rangeland vegetation in the northern Rockies [Chapter 6]

Publications Posted on: October 02, 2017
A longer growing season with climate change is expected to increase net primary productivity of many rangeland types, especially those dominated by grasses, although responses will depend on local climate and soil conditions. Elevated atmospheric carbon dioxide may increase water use efficiency and productivity of some species.

Scientists conserve the seeds of today to propagate the best adapted plants of tomorrow

Science Spotlights Posted on: October 13, 2016
Faced with extensive disturbances and climatological challenges that are rapidly changing ecosystems, scientists and land managers require the seeds of today to provide the plants of tomorrow. Researchers are currently studying more than 50 plant species in order to select best adapted plants to current and future climate conditions.

Effect of repeated burning on plant and soil carbon and nitrogen in cheatgrass (Bromus tectorum) dominated ecosystems

Publications Posted on: July 14, 2015
Fire has profound effects on ecosystem properties, but few studies have addressed the effect of repeated burns on soil nutrients, and none have been conducted in cold desert ecosystems where invasion by exotic annual grasses is resulting in greater fire frequency.

Decision support: Vulnerability, conservation, and restoration (Chapter 8)

Publications Posted on: August 07, 2012
Current predictive tools, management options, restoration paradigms, and conservation programs are insufficient to meet the challenges of climate change in western North America. Scientific and management capabilities and resources will be sapped trying to identify risks to genetic resources and ecosystems and determine new approaches for mitigating and managing changing environments.

Invasive species and climate change (Chapter 7)

Publications Posted on: August 07, 2012
Invasive species present one of the greatest threats to the health and sustainability of ecosystems worldwide. Invasive plants, animals, and diseases are known to have significant negative effects on biological diversity and the ecological structure and functions of native ecosystems.

Disturbance and Climate Change in the Interior West (Chapter 6)

Publications Posted on: August 07, 2012
Within the continental United States, average annual temperature increased during the Twentieth Century by approximately 0.65 ºC. The most extreme warming occurred throughout the northern and western United States (IPCC 2007a; Williams and others 2010). Disturbances such as fire, drought, grazing, urbanization, and energy development are predicted to have a heightened impact on the western United States under a changing climate.

Climate change, animal species, and habitats: Adaptation and issues (Chapter 5)

Publications Posted on: August 07, 2012
Because the rate of anthropogenic climate change exceeds the adaptive capacity of many animal and plant species, the scientific community anticipates negative consequences for ecosystems. Changes in climate have expanded, contracted, or shifted the climate niches of many species, often resulting in shifting geographic ranges.

Plant vulnerabilities and genetic adaptation (Chapter 4)

Publications Posted on: August 07, 2012
The biogeography of plant species and population genetic structure within species is principally governed by climate. The association between climate change and plant distributions has been well documented since the last ice age, and recent studies have shown contemporary climate changes can create landscape-scale die-offs or movement of plant taxa.
