CASE STUDIES

Putting microclimate and biophysical models to work in the mountains of Colorado

TrEnCh projects in the mountains of Colorado are repeating historical field observations and field and lab experiments as well as measuring historical specimens to examine ecological and evolutionary responses to recent climate change.
