Up Up and Away

- How might mountains differ from other habitats in terms of serving as a refuge during major changes in climate?
- How might body size or ability to migrate affect an animal or plant’s ability to adapt in montane environments?
- To what extent do you imagine the rocky corridors that Millar suggests as a conservation strategy might work for pikas? What are some reasons why they might be successful? Not successful?
- What do you imagine are the main reasons behind the pika population crashes in the Ruby Range? What conservation strategies might minimize these crashes?
- Why should we be concerned about individual species loss when systems adjust and some species will “win” and others will “lose”?
- Why is the pika a poster child for the impact of climate change on biodiversity?
- Why was the American pika not listed under the Endangered Species Act in 2010 (see below for readings)?
