The Rohr et al paper is consistent with the spread of Bd causing amphibian decline. Suggest people read Skerratt et al (2007) which is available at http://www.jcu.edu.au/school/phtm/PHTM/frogs/chart.htm for analysis of the evidence for spread of Bd causing amphibian decline. This has been generally accepted by the scientific community, wildlife managers and conservation agencies. For example the World Animal Health Organisation has made Bd a notifiable disease in order to prevent its spread, one of the two major aims of the Australian Government Threat Abatement Plan for chytridiomycosis is to prevent its spread, at the PARC meeting in Arizona last year chytridiomycosis experts and wildlife managers agreed that the major reason for Bd emergence was its spread and current emergency response plans to Bd around the world are based on the fact that Bd is currently spreading into naive populations.

This is a really interesting article and I'm currently writing a paper about amphibian decline for a class. I was wondering if you had the papers these results were published in. I was under the impression from "Widespread amphibian extinctions from epidemic disease driven by global warming" by Pounds et. al that the climate driven hypothesis was pretty correct at least for Costa Rica.
