A new study involving LTRR's Dr. Margaret Evans suggests climate change is happening faster than trees can adapt. The finding offers "a word of caution for ecologists" studying climate change. Read more in the link.

Arizona will soon regulate groundwater use near Douglas. What will change for water users? Read more in the link below.

In the same lab where University of Arizona scientists invented ways to decipher Earth's climate history in tree rings, LTRR's associate professor Bryan Black is using a similar technique – but with tiny fish bones. Check out the story in the link.
