Do copulation duration and sexual size dimorphism vary with absolute abundance in red millipedes Centrobolus Cook, 1897?


Author(s): Mark Ian Cooper

Abstract: Sexual Size Dimorphism (SSD), copulation duration, and absolute abundance were checked for correlations in the red millipede genus Centrobolus. There was a significant relationship between SSD and absolute abundance (r=0.63, Z score=1.66, n=8, p<0.05). Greater SSD was related to a higher absolute abundance of C. inscriptus over C. anulatus. There was an absolute difference (326) (T-score=1.99, d. f. = 6, p<0.05) and a relative difference (7.27) in absolute abundances between species (T-score=3.60, d. f. =6, p<0.01). Absolute abundances were higher in the trees (Z score=2.46, d. f. =10, p<0.01). Absolute densities were higher late in the season (Z score=-124, n=6, 6, p=0). Copulation duration increased with absolute abundance (r=0.63, Z score=1.66, n=8, p=0.049).
