Andrew Linscott/Getty Images(NEW YORK) Researchers in Africa have discovered a way to weaken large criminal networks responsible for the poaching that threatens vulnerable species all over the continent. DNA from the tusks of 4,320 African savanna elephants has identified networks for trafficking ivory out of Africa, according to a study published in Nature Human Behavior Monday. The authors of the study, University of Washington biologist Samuel Wasser and Nairobi Homeland Security Investigations assistant attaché John Brown III, were able to use previous work that identified tusks from the same elephant as well as close relatives found in different seizures, therefore revealing links between those shipments and their movements across the country. The findings showed that the majority of the 49 large ivory seizures (totaling 122 tons) shipped out of Africa between 2002 and 2019 contained tusks from repeated poaching of the same elephant populations.
