21 December 2011 Scientists and the public usually rejoice when a new species is discovered. But biologist Bryan Stuart has learned the hard way that the discovery of new species, especially when that species is commercially valuable, has a dark side-one that could potentially wipe out the new species before protections can be put in place. Stuart has discovered 27 species unknown previously to scientists – so far. That includes 22 species of frogs, three types of snakes, and two salamanders. His experience with one of these, a warty salamander from Laos with striking markings (Laotriton laoensis), opened his eyes to a dark side of scientific discovery: commercial overexploitation before protections are in place. Shortly after Stuart described the previously unknown species Laotriton (Paramesotriton) laoensis in a scientific paper published in 2002, commercial dealers began collecting this Lao newt for sale into the pet trade. In essence, the dealers used Stuart’s geographic description in the paper 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 was 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 scientific descriptions of new species may inadvertently facilitate their extinctions for commercially valuable species. Yet on the other hand, the conservation benefits of describing the new species can outweigh this potential risk. To reduce the potential tragedy, Stuart recommends that taxonomists work closely with relevant governmental agencies to coordinate publication of the description with legislation or management plans that can thwart overexploitation of the new species. Indeed, he and his students have worked tirelessly in this regard and, in August 2008, Laos’ Department of Forestry protected the Lao newt from commercial trade. Now, the remaining question is one of enforcement. […]
