摘要：In the originally published version of this article, the authors reported an incorrect entry, namely ‘‘Synclonal’’ in the ‘MTD pattern’’ column, in rows 5 (for speciesborealis)and6(forspeciescanadensis) in Table 1. This incorrect entry is now corrected with the appropriate entry, namely ‘‘Karyonidal’’. In addition, all the species names appear now in ‘‘italics’’ and with no capital letters. The correct table appears below.
