Dr. Behan and Dr. Breen regret these errors, of which the co-authors Marion Hogg, Ina Woods, Karen Coughlan, Mollie Mitchem and Jochen Prehn were completely unaware. We thank the reader for bringing this to our attention and sincerely apologize to the scientific community for any confusion or adverse consequences resulting from the publication of these data.
