Only a publisher can retract a published paper. An author can request that it be retracted, but the actual retraction is the function of the journal/publisher. Right everyone? Therefore, the Fish and Wildlife Service cannot properly say it has retracted the article. It may have requested the article’s retraction.
I have no information about the OU authors being disciplined. Also, let’s not minimize the malevolence of using a predatory journal to promote a scientific point. That’s really what my blog post is about, not the purported bad science.
