One species of cold-blooded vertebrate affected by collecting (ANY
collecting) is the green salamander, _Aneides aeneus_. It's a high-altitude,
rock crevice dwelling species native to the southern Appalachians. Chris
Wilson at Appalachian State Univ. in NC did his doctoral work surveying
several NC populations in the 1990s and observed a dramatic decline, both
during his field work and especially compared to earlier surveys from the
1970s. The species may actually be four species, all of which currently
exist as isolated "population islands". Several populations exist on public
lands. Both scientific and hobbyist/pet-trade collecting appear to have
contributed to destabilizing increasingly vulnerable populations (so-called
stochastic processes, or in this case, decline through random events).

For a review of WIlson's work and status of this salamander, go to:
