Effects of global change on alpine and subalpine ecosystems
Atmospheric nitrogen deposition, changing environmental patterns, and recreation are rapidly altering high elevation ecosystems. This project will evaluate long-term biogeochemical, hydrological, and ecological trends in Rocky Mountain National Park to understand the causes and rates of change in alpine and subalpine waters, soils, and vegetation. Resource managers of high-elevation, protected...
Interpreting Global Change Impacts on Southern Rocky Mountain Alpine and Subalpine Ecosystems for Effective Resource Management
Project Overview Human fossil fuel use and agricultural practices have increased atmospheric nitrogen deposits (e.g., through snow and rain) to mountain ecosystems. This, along with increasing measurable climate warming is affecting soil and water acidity and altering nutrient balances. In this project, North Central CASC-supported researchers will analyze decades of unexplored data...
Ecological Forecasting Workshop
Natural resource managers are coping with rapid changes in both environmental conditions and ecosystems. Enabled by recent advances in data collection and assimilation, short-term ecological forecasting may be a powerful tool to help resource managers anticipate impending changes in ecosystem dynamics (that is, the approaching near-term changes in ecosystems). Managers may use the...
Accelerating changes and transformations in western mountain lakes
While research into eutrophication has been a cornerstone of limnology for more than 100 years, only recently has it become a topic for the remote alpine lakes that are icons of protected national parks and wilderness areas. National park lakes in the western U.S. are threatened by global change, specifically air pollution, warming, and their interactions, and the problem is quickly worsening...
The Western Mountain Initiative (WMI)
Western Mountain Initiative (WMI) is a long-term collaboration between FORT, WERC, NOROCK, USFS, NPS, LANL, and universities worldwide to address changes in montane forests and watersheds due to climate change. Current emphases include altered forest disturbance regimes (fire, die-off, insect outbreaks) and hydrology; interactions between plants, water, snow, nutrient cycles, and climate; and...
Western Mountain Initiative: Central Rocky Mountains
Mountain ecosystems of the western U.S. provide irreplaceable goods and services such as water, wood, biodiversity, and recreational opportunities, but their responses to global changes are poorly understood. The overarching objective of the Western Mountain Initiative (WMI) is to understand and predict the responses, emphasizing sensitivities, thresholds, resistance, and resilience, of Western...

Ecosystem trends in the Colorado Rockies Ecosystem trends in the Colorado Rockies
Biological conservation is increasingly moving toward an ecosystem and landscape approach, recognizing the prohibitive cost and difficulty of a species-by-species approach (LaRoe 1993). Also, statewide (e.g., Gap Analysis Program) and national surveys (e.g., Environmental Monitoring and Assessment Program or EMAP) are conducted at a scale and level of resolution that do not meet the...

Analysis of nitrogen saturation potential in Rocky Mountain tundra and forest: implications for aquatic systems Analysis of nitrogen saturation potential in Rocky Mountain tundra and forest: implications for aquatic systems
We employed grass and forest versions of the CENTURY model under a range of N deposition values (0.02–1.60 g N m−2 y−1) to explore the possibility that high observed lake and stream N was due to terrestrial N saturation of alpine tundra and subalpine forest in Loch Vale Watershed, Rocky Mountain National Park, Colorado. Model results suggest that N is limiting to subalpine forest...

Effects of mesoscale vegetation distributions in mountainous terrain on local climate Effects of mesoscale vegetation distributions in mountainous terrain on local climate
Even a casual observer from an aircraft will note the varied landscape of mountainous terrain. These variations in land surface include the terrain features themselves as well as patchiness from different vegetation types, surface geology, urbanization, etc. There are two major questions related to climate system dynamics that need to be addressed concerning this landscape heterogeneity...

The influence of mountain meteorology on precipitation chemistry at low and high elevations of the Colorado Front Range, USA The influence of mountain meteorology on precipitation chemistry at low and high elevations of the Colorado Front Range, USA
We explored the seasonal characteristics in wet deposition chemistry for two sites located at different elevations along the east slope of the Colorado Front Range in Rocky Mountain National Park. Seasonally separated precipitation was stratified into highly concentrated (high salt), dilute (low salt), or acid-dominated precipitation groups. These groups and unstratified precipitation...

Winter phytoplankton dynamics in a subalpine lake, Colorado, U.S.A Winter phytoplankton dynamics in a subalpine lake, Colorado, U.S.A
The temporal dynamics of phytoplankton were examined in The Loch, a subalpine lake in Rocky Mountain National Park, over the winter seasons of 1987-88 and 1988-89. The Loch was ice-covered from early November until early to mid May. The pattern of phytoplankton biovolume during ice-cover was consistent between the two years with maxima occurring in November/December and February/March...
