In this paper, we develop a framework for explicitly separating the influence of extinction intensity and extinction selectivity on causing overall changes in the composition of the biota.

Caitlin (Ph.D. '16)  is currently working as the GSA-USGS Congressional Science Fellow in the office of Senator Tom Udall (D-NM). She published a piece in GSA Today this month (pg 50) describing the contributions that a geologist can make to science policy in Washington.  It is a terrific piece and not too long.  I urge you to read it!
