Detailed Description

-- are American pikas harbingers of changing conditions?

by USGS Research Ecologist Erik Beever


  • American pikas are denizens of rocky talus and lava-flow habitats in mountain ecosystems across western North America
  • Mountain environments, cauldrons of climatic harshness, exhibit sharp topographic, vegetative, and climatic gradients
  • Pikas are providing scientists with a model for assessing species vulnerability to warming temperatures
  • Are other species and indicators in the animal kingdom equally sensitive to changing climate conditions and warming temperatures?
