Genetic differentiation and population structure of four geographical krill groups. a The genetic diversity and differentiation among the four krill groups. Values within the circles represent the nucleotide diversity (π) at the group level, while values adjacent to the linked lines represent population differentiation (ФST), and the corresponding p-values are provided in parentheses. b Scatterplot showing the discriminant analysis of principal components (DAPC) of four groups from different geographical locations. The axes represent the first two linear discriminants. Each dot represents an individual, and each circle represents one cluster. c Bayesian phylogenetic tree depicting the relationships among the 80 krill samples. Different groups are represented by different colors, and bootstrap values are shown at the nodes. d The ФST values, calculated across the mitogenome, reflect the genetic differentiation among the four maternal genetic clusters and four geographical groups, respectively
