Sexual dimorphism across latitude in pill millipedes (Diplopoda)

Author(s): Mark Ian Cooper

Abstract: Sexual size dimorphism (SSD) was investigated across latitudes in southern African members of the pill millipede genus Sphaerotherium. Body width was extracted from published material (1928) and used to compare interspecific variation in mean calculated volumes using a morphometric approach. Based on the formula for a sphere (4/3. π. r3), volume was calculated in seven given species. A positive relationship between SSD and latitude (R = 0.71; Z score = 1.78, n=7, P = 0.04) was established.
