高品质的松露可卖到每磅1000美元。事实上，在环境研究中，科学家也用松露来吸引动物，因为它们也很爱吃这个。
Truffles Serve Up Environmental Info
Quality truffles can sell for more than a $1,000 a pound. They’re also valuable in environmental research, work that’s discussed in an article called "The Hidden Life of Truffles" in the April issue of Scientific American magazine, by Oregon State University’s James Trappe and Andrew Claridge, visiting fellow at the University of New South Wales in Australia.

Claridge is getting better estimates of Australian endangered species populations, thanks to truffles. Some marsupials are as crazy for truffles as some humans are. Claridge soaked foam pads with olive oil infused with the scent of European black Perigord truffles, and left the pads near motion-sensing cameras. The animals came in droves, with 50 times as many individuals counted as with other techniques. Claridge used the European truffle product because it was easy to get—his team will next see the reaction of native animals to native truffles.
Meanwhile, if you want spotted owls in the Pacific Northwest, you need flying squirrels, the bird’s favorite food. Which means you need an environment rich in the squirrel’s favorite food: truffles.
