Fig. 2. MATRIX-I (root-root transformed). A. Dendrogram of species distribution
affinities. B. MDS plot of species distribution affinities, pattern types in accordance with
Rulley [14]. Widespread + Tropical (solid circle), Subtropical (half-solid circle),
Convergence (open circle), Temperate (solid triangle), SubAntarctic (solid square),
Broadly Antarctic (half-solid square), Antarctic (open square). C. MDS plot of species
distribution affinities with genera and subgenera superimposed. Electrona (solid triangle),
Metelectrona (half-solid triangle), Hierops (open circle), Protomyctophum (solid circle),
Krefftichthys (half-solid square), Gymnoscopelus ( open square), Nasolychnus ( solid square)
Group B 1 consisted of Widespread, Tropical and Subtropical Pattern
species, except for D. meadi and D. ostenfeldi. Group B2 consisted of
Convergence and Bitemperate Pattern species, except for Symbolophorus
barnardi. Group C encompassed Antarctic Pattern species. Group Dl
consisted of Broadly Antarctic Pattern species, except for Electrona
carlsbergi and Lampanyctus achirus. Group D2 comprised SubAntarctic
