Greetings,
I ran into an interesting article that may be of interest. Check out Courchamp, et al. 2006. Rarity Value and Species Extinction: The Anthropogenic Effect. PLoS Biol 4(12): e415doi:10.1371/joiurnal.pbio.0040415.
The intro includes: "article makes the case that as populations become more sparse, it is increasingly costly to exploit them ... However less-abundant exploitation if their rarity makes them systematically more valuable... driving toward extinction."
