Dear readers,
I am very sorry to report that we recently noticed a major problem with the published supplementary file Table S1 in our paper. Somehow, published Table S1 contains incorrect raw data in the last two columns (values for ta and M). The conclusions of our paper are correct, as are all references to statistics and analyses in text – as the correct data of Table S1 was used throughout for all analyses: We sent incorrect version as supplementary file.

Corrected Table S1 will be replaced soon. At the meantime, corrected data of Table S1 will be available on request by email wangxia8383@gmail.com.

We apologise sincerely for this.
