There are bison on Catalina Island, left there by a film company around a hundred years ago. They are smaller than bison on the mainland: “They’re very challenged healthwise when they’re on this island because they don’t have the adequate nutrition during the right time of year,” King said. “So, our bison are in fact a little smaller than the mainland, and it’s not a genetic difference. It’s due to not having the right nutrients at the right time.” https://www.voanews.com/a/history-catalina-bison-hollywood-tourism-ecology/3930517.html https://www.voanews.com/a/history-catalina-bison-hollywood-t... The article also notes that bison from the island were relocated back to the mainland on three separate occasions to try to reestablish herds here. I can't currently find a citation, but I recall reading that bison that were returned to the mainland put on weight. It's well established that island populations of animals trend physically smaller. That part isn't at all news.
