The Columbus Zoo and Aquarium polar bear cubs arent just cute and cuddly. <\/p>\n
Theyre also helping the federal government fight crimes against their wild relatives in the Arctic, thanks to advancements in forensic science and DNA testing. <\/p>\n
The U.S. Fish and Wildlife Services Forensic Laboratory in Oregon often relies on zoos to maintain its database of DNA samples from protected animal species. But when the Columbus Zoo sent DNA from its six polar bears to the lab in March, it came with payoffs for both parties including a confirmation of whether the zoos three newest cubs are male or female. <\/p>\n
The labs scientists analyze evidence during investigations of violations of federal wildlife protection laws, including poaching, illegal trading of animals, theft of rare plants and creating products from endangered species. <\/p>\n
For example, the lab could use DNA to identify a decaying carcass as a protected animal or confirm that a business is selling items made with bald eagle feathers or elephant ivory. <\/p>\n
Scientists are trying to perfect a new, more accurate DNA test for bears and benefited from the Columbus Zoos controlled samples from a known family of animals. The reference data illustrate how genetic patterns change in a population over time. It could someday pin down criminals who harm polar bears, which are protected by the Marine Mammal Protection Act and the Endangered Species Act, on which the bears are listed as threatened. <\/p>\n
Only an estimated 20,000 to 25,000 polar bears are living in the wild, and there are just 40 or so bears in 27 U.S. zoos that are members of the Association of Zoos and Aquariums. <\/p>\n
Our polar bear database is fairly small, so the more samples we can get, the better, senior forensic scientist Mary Burnham Curtis said. <\/p>\n
The zoo, meanwhile, was seeking a noninvasive way to determine the sexes of its baby bears. Because the 6-month-old animals are being raised by their mothers and not hand-reared by zookeepers, staffers would have had to put them under anesthesia to examine their genitals and make an official determination. <\/p>\n
That seemed like an unnecessary risk for something that was just curiosity, not critical, said Randy Junge, the zoos vice president of animal health. <\/p>\n
Luckily, we were able to help each other out. <\/p>\n
