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.

We had a great dendro class and lab visit last week with students from Teenage Parent High School. Several of these young ladies are graduating in December and college-bound, having received scholarship! We had a great time focusing on the many applications of dendrochronology.
