ST. LOUIS — Poaching and habitat loss are driving a species of exotic cattle toward extinction in the wild. But scientists at the St. Louis Zoo are coming to the rescue — with fitness trackers. Researchers there used the bovine version of a Fitbit, combined with fecal samples, to uncover hidden patterns in the animals’ reproductive cycles. The results could be key to protecting the animals, called banteng, and scientists hope the data will boost the success of breeding efforts. The discovery arrives as the zoo forges ahead with plans for its WildCare Park, which is designed partly to help scie...
