Please record the following information for Manuela Huso: We are writing concerning our omission of a coauthor associated with our recent article: Manuela Huso, who was not included as a coauthor during the submission and revision stages of this work, made significant contributions to statistical aspects of this study that we believe merit coauthorship. These contributions involved: (1) assisting substantively with the overall statistical design, and (2) deriving an approach to numerical approximation of the area under the curve in a mass-loss function, which produced a single k-value from complex mass-loss patterns that allowed cross-species comparisons. a.
