The WildLife: The Dark Side of New Species Discovery, Bryan Stuart
Bryan Stuart, curator of amphibians and reptiles at the North Carolina Museum of Natural Sciences, talks about the dark side of the discovery of new species. He tells “The WildLife” host Laurel Neme about his experience following his scientific discovery in Laos of a warty salamander (Paramesotriton laoensis) with striking markings. Shortly after describing the previously unknown species in a scientific paper published in 2002, commercial dealers began collecting the salamanders for sale into the pet trade. Particularly galling to Bryan was the fact that they used his geographic description as a roadmap to find the rare newt. This situation is not unique. It’s also happened with a turtle (Chelodina mccordi) from the small Indonesian island of Roti, which so heavily hunted that today it is nearly extinct in the wild. Similarly, a rare gecko (Goniurosaurus luii) from southeastern China was extirpated from its locality as prices in importing countries soared to highs of $1,500 to $2,000 each. It’s a dual dilemma. On the one hand, publishing new species descriptions may inadvertently facilitate their extinctions for commercially valuable species, yet on the other, the conservation benefits of describing the new species can outweigh this potential risk. Bryan recommends that taxonomists work closely with relevant governmental agencies to coordinate publication of the description with legislation or management plans that thwart overexploitation of the new species. In fact, Bryan and his students have worked tirelessly in this regard and, in August 2008, Laos’ Department of Forestry protected this salamander from commercial trade. Now the remaining question is enforcement. Note: Laurel first met Bryan while researching a wildlife trafficking case for ABC News Nightline that involved the illegal import of hundreds of these rare salamanders that were dried and destined for traditional medicine.
Bryan Stuart is curator of amphibians and reptiles at the North Carolina Museum of Natural Sciences. He received his Bachelor of Science (B.Sc.) in biology from Cornell University, a Master of Science (M.Sc.) in zoology from North Carolina State University, and a Ph.D. in biology from the University of Illinois. He also held a post-doctoral appointment at the Museum of Vertebrate Zoology at the University of California, Berkeley, before returning to Raleigh to join the North Carolina Museum of Natural Sciences in September 2008. His research interests are in the biodiversity, systematics, biogeography and conservation of amphibians and reptiles. Much of his research has focused on amphibians and reptiles of the Old World tropics, especially Southeast Asia, where he has maintained an active field program for the past decade. He has particular interest in using molecular tools to define species boundaries and unravel their evolutionary histories.
