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...

Options for national parks and reserves for adapting to climate change Options for national parks and reserves for adapting to climate change
Past and present climate has shaped the valued ecosystems currently protected in parks and reserves, but future climate change will redefine these conditions. Continued conservation as climate changes will require thinking differently about resource management than we have in the past; we present some logical steps and tools for doing so. Three critical tenets underpin future management...

Compound-specific stable isotopes of organic compounds from lake sediments track recent environmental changes in an alpine ecosystem, Rocky Mountain National Park, Colorado Compound-specific stable isotopes of organic compounds from lake sediments track recent environmental changes in an alpine ecosystem, Rocky Mountain National Park, Colorado
Compound-specific nitrogen, carbon, and hydrogen isotope records from sediments of Sky Pond, an alpine lake in Rocky Mountain National Park (Colorado, United States of America), were used to evaluate factors contributing to changes in diatom assemblages and bulk organic nitrogen isotope records identified in lake sediments across Colorado, Wyoming, and southern Montana. Nitrogen isotopic...

Spatial patterns of simulated transpiration response to climate variability in a snow dominated mountain ecosystem Spatial patterns of simulated transpiration response to climate variability in a snow dominated mountain ecosystem
Transpiration is an important component of soil water storage and stream-flow and is linked with ecosystem productivity, species distribution, and ecosystem health. In mountain environments, complex topography creates heterogeneity in key controls on transpiration as well as logistical challenges for collecting representative measurements. In these settings, ecosystem models can be used...

Some guidelines for helping natural resources adapt to climate change Some guidelines for helping natural resources adapt to climate change
The changes occurring in mountain regions are an epitome of climate change. The dramatic shrinkage of major glaciers over the past century – and especially in the last 30 years – is one of several iconic images that have come to symbolize climate change. Climate creates the context for ecosystems, and climate variables strongly influence the structure, composition, and processes that...

A report by the U.S. Climate Change Science Program and the Subcommittee on Global Change Research Preliminary review of adaptation options for climate-sensitive ecosystems and resources. A report by the U.S. Climate Change Science Program and the Subcommittee on Global Change Research
Climate variables are key determinants of geographic distributions and biophysical characteristics of ecosystems, communities, and species. Climate change is therefore affecting many species attributes, ecological interactions, and ecosystem processes. Because changes in the climate system will continue into the future regardless of emissions mitigation, strategies for protecting climate...

As attributes of the Earth's ecosystems shift in the face of human impact and sustainability of ecosystem services becomes less certain, one important tool at the disposal of the scientific community and other groups is a blueprint for understanding, evaluating, and communicating the value of ecological services. The blueprint presented here is based on (1) an examination of the...

Application of a coupled ecosystem-chemical equilibrium model, DayCent-Chem, to stream and soil chemistry in a Rocky Mountain watershed Application of a coupled ecosystem-chemical equilibrium model, DayCent-Chem, to stream and soil chemistry in a Rocky Mountain watershed
Atmospheric deposition of sulfur and nitrogen species have the potential to acidify terrestrial and aquatic ecosystems, but nitrate and ammonium are also critical nutrients for plant and microbial productivity. Both the ecological response and the hydrochemical response to atmospheric deposition are of interest to regulatory and land management agencies. We developed a non-spatial...
