1 . Conservation scientist Kim Williams-Guillen was trying her best to come up with a way to save endangered sea turtles (海龟) from egg thieves when she had an “aha” moment: If she placed a fake (假的) egg containing a GPS tracker in the reptiles’ nests, she might be able to track the thieves.
Williams-Guillen found a flexible plastic material to mimic (仿造) the shell of real eggs. She and colleagues then used a 3D printer to produce the fakes of the same size, weight, and texture and put the smallest GPS tracking devices inside each. The researchers then went to four Costa Rican beaches, where green sea turtle come ashore to make their nests. As mothers laid their eggs under cover of night, the researchers slipped a fake egg into each nest. Once the fakes are covered in sand and mix with the real eggs, it’s very difficult to tell the difference between the two.
Of the 101 fake eggs, 25 were taken by thieves. The farthest moving egg traveled 137 kilometers inland. The fake egg sent its final signal the next day from a residential property, suggesting that the research team had tracked the eggs through “all of the players in the entire chain.”
By understanding that chain, Williams-Guillen says researchers can identify trading hot spots. She emphasizes that the tracker is not a way to catch local thieves, many of them living in poverty, but a tool to better understand their routes, which could help them and eventually law enforcement (执法部门) identify larger players in the chain.
In the meantime, Williams-Guillen and her colleagues are working to get their fake eggs to other sea turtle conservation organizations. Ultimately, though, scientists and nonprofits are going to engage communities with local outreach and education programs to save sea turtles. She says, “The real meat and potatoes of conservation isn’t going to come from deploying (布署) eggs.”
