Wow. I didn't realize it was in as many places as it is. It's only been in the last year or so that I have really heard about it, but I don't know the history behind it. I remember an article I read near the beginning that made it sound like only tadpoles were truly affected, but I know now that is not true. This may be a really dumb question, but what do you mean by "Old World" amphibians? Are newts and salamanders equally affected (I don't hear about them much in such articles...)?
