  The raw data from study of variation of D-loop mtDNA of white sturgeon
Acipenser transmontanus (Mol. Biol. Evol. 1993. 10: 326-341) was re-analyzed.
Re-calculated nucleotide substitution rate ({\mu}) was 0.782-0.939 x 10-7
substitutions/site/year/lineage, which was 1.4 times less than the estimate
given in above-mentioned publication. The use of new {\mu} has led to an
increase in estimates of long-term female effective population size (Nef) and
coalescence times for mtDNA haplotypes, previously calculated for samples of
Amur sturgeon A. schrenckii and kaluga A. dauricus, but it did not affect the
conclusions on the critical state of their natural populations.
