The authors acknowledge that their article (Montgomery et al., Reference Montgomery, Hamel and Mercier2019) contained six conversion errors (out of the 161 records); two duplicate records were removed, and references were also updated in the supplementary file (S1).
The main findings of our original paper remain unchanged with these corrections and adjusted statistics (Figures 1–4).
The authors thank Lanna and Riesgo (Reference Lanna and Riesgo2019) both for identifying these errors and the new records they have provided, and apologise to the Journal's readers.
