Community-Specific Biogeochemical Responses to Atmospheric Nitrogen Deposition in Subalpine Ecosystems

Dates

Start Date
2014
End Date
2016

Summary

Elevated anthropogenic nitrogen (N) emissions are causing higher rates of atmospheric N deposition (Ndep) that may saturate Cascade ecosystems with reactive N. Simultaneously, increasing global temperatures and altered circulation patterns generated by climate change are expected to strongly impact snow regimes in the Cascade Range, causing reduced snowpack, earlier snowmelt dates, and higher proportions of rain precipitation. Concern over the impacts of Ndep to sensitive, high-elevation ecosystems has prompted calls for research into its interaction with climate change and the effects of Ndep on ecosystem services. This is a collaborative project between the National Park Service and Washington State University to improve understanding [...]
