I was wondering if any research has been focused on the radiation of the Dendrobatidae into Panama and Costa Rica since the formation of the isthmus of Panama around 2.5-3 mya.
No but I would check in with Drs. Kelly Zamudio, Karen Lipps or Joseph Mendelson III
Thanks for that Gordon, I shall spend the next couple of days looking into the research of the people you have mentioned above.
Hi Steven
i only know one article that may discuss the phylogeographie of the dendrobatid and their speciation pattern for the Amazonia, but in that paper they stablish many hypothesis, one with the istmus

Much research has been done in Panama on the radiation of Dendrobatids. Just have a look at the internet and check papers by C.W. Myers (who discovered the radiation in Bocas del Toro), Myers and J. Daly, also check for Dendrobates pumilio and you will find a host of papers.

check for papers by Jeanne Robertson.

She worked with Kelly and Karen so you likely already found her....
