Project Title:Assessing Alpine Ecosystem Vulnerability to Environmental Change Using Dall Sheep as an Iconic Indicator Species
Project Lead: Laura Prugh, University Of Washington
Project Funding: 2015 - 2019
NASA (agency representative: Eric Kasischke)
Project Type:NASA -- joined ABoVE in 2015
Solicitation:NASA: Terrestrial Ecology (2014)
Abstract: Dall sheep are an emblem of the North. The global distribution of this iconic species is contained entirely within the Arctic and boreal region of northwestern North America, and the rapid changes associated with a warming climate throughout the ABoVE domain therefore have profound implications for this species and the ecosystem services it provide ...
