PLoS ONE: Size, Rarity and Charisma: Valuing African Wildlife Trophies

PLoS ONE: Size, Rarity and Charisma: Valuing African Wildlife Trophies: "We explore variation in the prices paid by recreational hunters of trophy animals in Africa and its possible causes, including perceived rarity. Previous work has raised the possibility that extinction can result if demand rises fast enough as a species becomes rarer. We attempt to disentangle this from other inter-correlated influences affecting price."
