"At Otokiki, similar large variation in colors and patterns is represented in quadrats under management by Wikiri (three habitat-enriched semiclosed enclosures, one enriched open quadrat), and in one control (not enriched) quadrat."
The variation that we are seeing currently in the hobby is what the population currently is today in the Otokiki Reserve...Could this population have been manipulated by humans 20 years ago?...Sure, but unless someone has a time machine we won't know that for sure. What we do know for sure is that there are yellow, red, brown, etc., etc. phenotype frogs in the same general area in the reserve. This is a snapshot of the population as it is today.
The quote above explains that the natural variation in the control plot is very close to the variation in plots that those involved with this program have manipulated to provide us with these frogs. Nowhere in the remarks about the research going on with these frogs have I found them (Wikiri) questioning whether the variation is natural or unnatural. They are researching the cause of the variation, not the credibility.
The people involved with this program have done a great service to us by providing CB legal large obligates. They also live with the frogs and have seen them in their natural habitat for years. They know what they're doing...I have no reason to doubt them. If they wanted us to keep them separate phenotypically, they would be brought in as O. sylvatica 'Paru-red', 'Paru-yellow', etc., etc. In my opinion, it would be unwise of us to potentially limit the genetic variability of captive populations (of a frog that has been notorioulsly hard to keep in the hobby in the past...) by deciding on our own that there are separate morphs within the overarching locale 'Paru'.
