ABSTRACT

I tested for relationships between male and female surface-area-to-volume ratios and abundance in red millipedes Centrobolus. Female surface areas appeared related to abundance (r=-0.63, Z score=-1.66, n=8, p<0.05). Male surface areas appeared related to abundance (r=0.63, Z score=1.66, n=8, p<0.05). There was no relationship between surface areas and abundance when the sexes were pooled (r=0.12, Z score=0.43, n=16, p=0.33). There was no relationship in species surface areas alone i. e. C. inscriptus (r=0, Z score=0, n=8, p=0.50) or C. anulatus (r=0, Z score=0, n=8, p=0.50).

Key words: Abundance, male, female
