Risk assessment in the face of a changing environment: Gypsy moth and climate change in Utah

Publications Posted on: March 04, 2020
The importance of efficaciously assessing the risk for introduction and establishment of pest species is an increasingly important ecological and economic issue. Evaluation of climate is fundamental to determining the potential success of an introduced or invasive insect pest. However, evaluating climatic suitability poses substantial difficulties; climate can be measured and assessed in a bewildering array of ways.

Changes in soil organic carbon contents and fractionations of forests along a climatic gradient in China

Publications Posted on: October 02, 2019
Soil organic carbon (SOC) is a large reservoir of terrestrial carbon (C); it consists of different fractions of varying complexity and stability. Partitioning SOC into different pools of decomposability help better predict the trend of changes in SOC dynamics under climate change.

Global warming of salmon and trout rivers in the northwestern U.S.: Road to ruin or path through purgatory?

Publications Posted on: April 23, 2018
Large rivers constitute small portions of drainage networks but provide important migratory habitats and fisheries for salmon and trout when and where temperatures are sufficiently cold. Management and conservation of cold‐water fishes in the current era of rapid climate change requires knowing how riverine thermal environments are evolving and the potential for detrimental biological impacts.

NorWeST modeled summer stream temperature scenarios for the western U.S.

Datasets Posted on: March 15, 2018
NorWeST summer stream temperature scenarios were developed for all rivers and streams in the western U.S. from the > 20,000 stream sites in the NorWeST database where mean August stream temperatures were recorded.

NorWeST stream temperature data summaries for the western U.S.

Datasets Posted on: March 15, 2018
NorWeST is an interagency stream temperature database and model for the western United States containing data from over 20,000 unique stream locations. Temperature observations were solicited from state, federal, tribal, private, and municipal resource organizations and processed using a custom cleaning script developed by Gwynne Chandler. Summaries of daily, weekly, and monthly means, minima, and maxima are provided for observation years.

Redistribution of vegetation zones and populations of Larix sibirica Ledb. and Pinus sylvestris L. in central Siberia in a warming climate

Publications Posted on: May 12, 2016
Evidence for global warming over the past 200 years is overwhelming (Hulme et al. 1999), based on both direct weather observation and indirect physical and biological indicators such as retreating glaciers and snow/ice cover, increasing sea level, and longer growing seasons (IPCC 2001). Recent GCM projections of the Hadley Centre (Gordon et al.

Cold-water fishes and climate change in North America

Publications Posted on: January 15, 2016
Trout, salmon, grayling and whitefishes (Salmonidae) are among the most ecologically and economically important fishes. They also are among the most vulnerable to global warming, and increasing drought, floods, and wildfires. In North America, salmonids occur from central Mexico northward along coastal regions and mountainous interiors to the Arctic Plains.

CO2, CH4 and N2O flux through a Wyoming snowpack and implications for global budgets

Publications Posted on: May 28, 2015
Increasing atmospheric concentrations of the three main greenhouse gases-carbon dioxide, methane, and nitrous oxide account for about 70% of anticipated global warming, but the production-consumption budgets are not balanced for any of these gases2. Snow can cover between 44 and 53% of the land area of the Northern Hemisphere3 and may be several metres deep in alpine and sub-alpine regions for more than half the year.

Climate shield cold-water refuge streams for preserving native trout

Documents and Media Posted on: March 18, 2015
Crowd-sourced biological datasets contributed by multiple agencies were coupled with high-resolution NorWeST stream temperature scenarios to delineate invasion resistant, climate refuge streams across >450,000 stream kilometers in the northwestern U.S. for two native trout species of concern — Bull Trout and Cutthroat Trout.Document Type: Briefing Papers

Climate shield cold-water refuge streams for native trout

Projects Posted on: March 18, 2015
The Climate Shield website hosts geospatial data and related information on specific locations of cold-water refuge streams for native cutthroat trout and bull trout across the American West. Forecasts about the locations of refugia could enable the protection of key watersheds, be used to rally support among multiple stakeholders, and provide a foundation for planning climate-smart conservation networks that improve the odds of preserving native trout populations through the 21st century.
