Modeling mountain pine beetle (Dendroctonus ponderosae) oviposition

Publications Posted on: July 08, 2019
Mountain pine beetle, Dendroctonus ponderosae Hopkins (Coleoptera: Curculionidae, Scolytinae), is a significant forest disturbance agent with a widespread distribution in western North America. Population success is influenced by temperatures that drive phenology and ultimately the adult emergence synchrony required to mass attack and kill host trees during outbreaks.

Ips typographus and Dendroctonus ponderosae models project thermal suitability for intra- and inter-continental establishment in a changing climate

Publications Posted on: July 08, 2019
Climate change is altering legacies of native insect-caused disturbances and contributing to non-native invasions globally. Many insect fitness traits are temperature dependent and projected climatic changes are expected to cause continued alterations in insect-caused tree mortality, with uncertain consequences for forest ecosystems and their management.

A tool for projecting rangeland vegetation response to management and climate

Publications Posted on: July 01, 2019
New technologies may enhance management by enabling quantitative testing of assumptions of vegetation response to climate and management. State-and-transition simulation models can keep track of interactions that are too complicated for us to comprehend using only conceptual models. This tool takes conceptual state-and-transition models to the next level, fostering greater communication and dialogue with stakeholders.

Great Basin bristlecone pine volatiles as a climate change signal across environmental gradients

Publications Posted on: June 14, 2019
Alpine treeline species, like Great Basin bristlecone pine (GBBP) (Pinus longaeva Bailey), have received attention for their potential as indicators of climate change. Most studies have focused on climate-induced changes to treeline position, but climate effects on the physiology and stress of treeline plants remain poorly understood.

Climate change likely to reshape vegetation across North America's protected areas

Science Spotlights Posted on: May 23, 2019
National parks, wilderness areas, and nature reserves were created to preserve a sample of pristine ecosystems, but even the most remote protected areas face serious threats from climate change. Managers would benefit from a better understanding how ecosystems within protected areas may respond to global warming.  

Climate change likely to reshape vegetation in North America's largest protected areas

Publications Posted on: May 22, 2019
Climate change poses a serious threat to biodiversity and unprecedented challenges to the preservation and protection of natural landscapes. We evaluated how climate change might affect vegetation in 22 of the largest and most iconic protected area (PA) complexes across North America.

Adaptation to future water shortages in the United States caused by population growth and climate change

Publications Posted on: May 22, 2019
Population growth and climate change will combine to pose substantial challenges for water management in the United States. Projections of water supply and demand over the 21st century show that in the absence of further adaptation efforts, serious water shortages are likely in some regions. Continued improvements in water use efficiency are likely but will be insufficient to avoid future shortages.

Guidelines for aspen restoration in Utah with applicability to the Intermountain West

Publications Posted on: May 07, 2019
As highly productive and biologically diverse communities, healthy quaking aspen (Populus tremuloides; hereafter aspen) forests provide a wide range of ecosystem services across western North America. Western aspen decline during the last century has been attributed to several causes and their interactions, including altered fire regimes, drought, excessive use by domestic and wild ungulates, and conifer encroachment.

Reforestation Matters

Science Spotlights Posted on: May 01, 2019
The number of global initiatives for forest restoration, and the scope of these initiatives, continues to increase. An important tool for meeting objectives of these global initiatives is reforestation, achieved by natural processes or by tree planting. Worldwide, organizations are challenged to most efficiently and effectively direct resources to the most critical reforestation needs. Currently in the United States, the reforestation efforts of the USDA Forest Service, are challenged by changes in policy, funding, climate change, and mega-fires, to name a few, and identifying strategies for timely successful reforestation at scale is needed.
