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 responses to nitrogen deposition in the Colorado Front Range Ecosystem responses to nitrogen deposition in the Colorado Front Range
We asked whether 3–5 kg N y−1 atmospheric N deposition was sufficient to have influenced natural, otherwise undisturbed, terrestrial and aquatic ecosystems of the Colorado Front Range by comparing ecosystem processes and properties east and west of the Continental Divide. The eastern side receives elevated N deposition from urban, agricultural, and industrial sources, compared with 1–2...

Management of land use conflicts in the United States Rocky Mountains Management of land use conflicts in the United States Rocky Mountains
People have long been attracted to the beauty and grandeur of the Rocky Mountains. Until very recently, however, the Rocky Mountain region was sparsely populated and its use mostly extractive. Commodities removed in massive quantities included first beaver, then precious metals, timber, energy, and finally water. There has been a fundamental change in migration patterns since the 1980s

Sensitivity of a high-elevation Rocky Mountain watershed to altered climate and CO2 Sensitivity of a high-elevation Rocky Mountain watershed to altered climate and CO2
We explored the hydrologic and ecological responses of a headwater mountain catchment, Loch Vale watershed, to climate change and doubling of atmospheric CO2 scenarios using the Regional Hydro-Ecological Simulation System (RHESSys). A slight (2°C) cooling, comparable to conditions observed over the past 40 years, led to greater snowpack and slightly less runoff, evaporation...

Stream chemistry modeling of two watersheds in the Front Range, Colorado Stream chemistry modeling of two watersheds in the Front Range, Colorado
We investigated the hydrologic, geochemical, and biogeochemical controls on stream chemical composition on the Green Lakes Valley and Andrews Creek watersheds using the alpine hydrochemical model (AHM). Both sites had comparable data sets from 1994 and 1996, including high‐resolution spatial data and high‐frequency time series of hydrology, geochemistry, and meteorology. The model of...

Temporal coherence of two alpine lake basins of the Colorado Front Range, USA Temporal coherence of two alpine lake basins of the Colorado Front Range, USA
1. Knowledge of synchrony in trends is important to determining regional responses of lakes to disturbances such as atmospheric deposition and climate change. We explored the temporal coherence of physical and chemical characteristics of two series of mostly alpine lakes in nearby basins of the Colorado Rocky Mountains. Using year-to-year variation over a 10-year period, we asked whether...

Combining binary decision tree and geostatistical methods to estimate snow distribution in a mountain watershed Combining binary decision tree and geostatistical methods to estimate snow distribution in a mountain watershed
We model the spatial distribution of snow across a mountain basin using an approach that combines binary decision tree and geostatistical techniques. In April 1997 and 1998, intensive snow surveys were conducted in the 6.9‐km2 Loch Vale watershed (LVWS), Rocky Mountain National Park, Colorado. Binary decision trees were used to model the large‐scale variations in snow depth, while the...

Preface [to special section on recent Loch Vale Watershed research] Preface [to special section on recent Loch Vale Watershed research]
Catchment-scale intensive and extensive research conducted over the last decade shows that our understanding of the biogeochemical and hydrologic processes in subalpine and alpine basins is not yet sufficiently mature to model and predict how biogeochemical transformations and surface water quality will change in response to climatic or human-driven changes in energy, water, and...

Spatial variation among lakes within landscapes: Ecological organization along lake chains Spatial variation among lakes within landscapes: Ecological organization along lake chains
Although limnologists have long been interested in regional patterns in lake attributes, only recently have they considered lakes connected and organized across the landscape, rather than as spatially independent entities. Here we explore the spatial organization of lake districts through the concept of landscape position, a concept that considers lakes longitudinally along gradients of
