In the version of this Article originally published there were some errors in the data in Table 1. For model 5 the P value should have been 2.18 × 10–7 not 2.19 × 10–7; for model 8 it should have been 0 not 3.0 × 10–4; for model 14 it should have been 1 × 10–3 not 8.0 × 10–4. The r2 value for model 7 should have been 0.14 not 0.15. The AICc value for model 12 should have been 21 not 22. Further, a technical error led to some values not appearing as bold: for model 4, 0.10 on the bottom arrow; for model 5, 0.15 on the top arrow; for model 13, the AICc value 7. All these errors have now been amended.
