--- ## Response to past and future climate change options: 1. Die 2. Sit tight and hang on for the ride (hope for no glaciers) 3. Migrate 4. Evolve ---
--- ## The data suggests that: - Migration was the primary response to the ice ages - These migrations were highly individualistic - no two species behaved alike source and more reading Williams et al. 1999 --- class: center, middle, inverse #Dispersal kernel
