I read the paper. Yes, it had been already suggested by others (Duellman, for instance) that these two species were possibly closely related. I am not sure the relevance of this paper other than reproduction in order to produce a paper (damn the prevailing ‘publish or perish’ attitude in the scientific community!). There are many allopatric species that will, given the chance, cross reproduce. Just look at the hobby.

Okay, both species are threatened by chytrid. Both species seem to holding their own in altered habitat (coffee plantations: A. annae near San Jose, A. moreletti in El Salvador). But what relevance does this paper have on addressing Bd or conservation?

I admire the Manchester Museum’s captive breeding program via the internet. But I’m not sure that a paper describing a hybrid warrants publication or attention…….just a thought.
