Median-joining haplotype networks of the available COI sequences of bumble bees from Novaya Zemlya and other Arctic areas. (A) Bombus hyperboreus. (B) B. pyrrhopygus. (C) B. glacialis. The circle size is proportional to the number of available sequences belonging to a certain haplotype (smallest circle = one sequence). The small black dots indicate hypothetical ancestral haplotypes. Red numbers near branches indicate the number of nucleotide substitutions between haplotypes.
