The Open Robust Model methods used for analysis in this study were developed by Kendall and Bjorkland (2001) and Kendall (2010). The language used in this manuscript to describe formatting and implementation of data for these analyses was derived heavily from Phillips et al. (2014). Therefore, the wording in the last paragraph of the ‘Materials and methods’ (p. 2662) and in the last paragraph of the ‘Results’ (p. 2663) of our publication is largely identical to the corresponding sections on pp. 865–866 in Phillips et al. (2014). Unfortunately, we did not indicate this adequately, thus proper credit was not given to the contribution of Phillips et al. (2014) in our publication.
