book of taxonomy?

[Tara Garratt]

Hi everyone.

I have an odd question. Is there a book or information available regarding the taxonomy for the subspecies of dendrobates? Is there information out there that tells people what criteria to look for in species and subspecies of these frogs? I have been looking, but have not been especially successful in finding anything. There are so many subspecies and each looks so different. I would like to find information regarding the criteria one should look for--what makes the subspecies special (eg. size, colour patern, body structure etc.). I hope people understand what I mean.

Any help would be appreciated.

Thanks,
