Meet our Faculty: Karl Flessa

Karl Flessa stands at the Colorado River pulse flowI am interested in using fossils in conservation biology. My students, colleagues and I have documented environmental conditions, species populations, and species interactions in the Colorado River Delta before upstream dams and diversions. We work on very young, “predambrian” fossils. I am now working with partners in U.S. and Mexican conservation groups, agencies and universities to monitor restoration efforts in the delta’s riparian zone and estuary. We use ecological and paleoecological techniques, including stable isotope analyses of carbonates and water, to “put the dead to work” in assessing environmental impact and guiding restoration.
