Blake Hossack's research is focused on measuring population and community responses to climate change, energy development, invasive species, and wetland mitigation and management. Most of his research is focused on wetlands and amphibians, with long-term research areas in the Crown of the Continent Ecosystem (Montana), Greater Yellowstone Ecosystem (Wyoming), southern Arizona and Mexico, the northern Great Plains, and the subarctic (Manitoba). To improve conservation success, Blake has increasingly sought to integrate research into management applications. He is stationed at the Aldo Leopold Wilderness Research Institute in Missoula, Montana, where he coordinates activities for the Amphibian Research and Monitoring Initiative (ARMI) in the Northern Rockies and Desert Southwest.


Current Research Projects:

  • Long-term research on amphibians and wetlands in the Desert Southwest, Greater Yellowstone Ecosystem, and Crown of the Continent Ecosystem.
  • Designing citizen science programs for research on effects of climate change on wetland metacommunities in the Canadian Subarctic.
  • Measurement of the threat of climate to aquatic species, their capacity for local adaptation, and adaptive management to reduce threats.
  • Linking variation in stream flows and disease to metapopulation dynamics in arid ecosystems.
  • Integrating metapopulation ecology and landscape ecology for improved population viability analysis and conservation decision-making.
  • Quantifying the value of mitigation and other constructed wetlands.
  • Assessing the long-term effects of wildfires on amphibians in wilderness and managed forests. 
  • Informing recovery of threatened and endangered amphibians in the US-Mexico Borderlands 
  • Effects of Energy Development in the Prairie Pothole Region on Water Quality and Aquatic Ecosystems (with Chauncey Anderson [USGS] and several others)
