Abstract

We collected sediment cores from three alpine lakes in Utah, United States, to isolate dormant Daphnia eggs for a resurrection ecology experiment. Our question was whether radioactive fallout from above-ground nuclear weapons testing at the Nevada Test Site in the 1950s and 1960s caused increased mutation rates and population evolution in Daphnia. That work is ongoing. Here, we publish radioisotope dating profiles from our sediment cores.
