Correction to: Scientific Reports https://doi.org/10.1038/s41598-019-42095-z, published online 10 April 2019

In the Supplementary Information file originally published with this Article, the University of Alaska Museum specimen IDs were omitted from Supplementary Datasets 1-4.

In addition, the original version of Table 2 contained an error in the Parameters column for the Linear model where,

b = 1.19 (1.02; 1.35)”

now reads:

a = 1.19 (1.02; 1.35)”

These errors have now been corrected in PDF and HTML versions of the Article, and in the accompanying Supplementary Information file.
