Amphibians -- are they going extinct or not?

OK.  This week I read an article in "American Scientist" claiming that virtually all amphibians all over the world had gone extinct and that an entire niche in our eco-systems was now empty with all kinds of unknown and dread consequences likely to ensue.

Then, not two days later, I read an article about harmful, invasive coqui frogs taking over the islands of Hawaii.  This frogs are allegedly harmful, but all I could tell from the article about their alleged harm is that they make a lot of noise and keep people awake == but they're regarded as pests.

Now people, which is it?  Are they dangerous pests multiplying out of control, or are they tragically, nearly extinct?

You just can't make this stuff up.  Sometimes I wonder if I'm Alice through the looking glass.
