Five factors affecting copulation duration in the breeding season in forest millipedes Centrobolus Cook, 1897
Author(s): Mark Ian Cooper
Abstract: The objectives of this study were to determine what happened when copulation duration varied with five factors in Centrobolus. The mean copulation duration was correlated with female width, male width, the month with the highest number of days with precipitation, moments of inertia, and precipitation of the forest millipede genus Centrobolus. There was a linear relationship between copulation duration and female width (r = 0.97, Z score = 2.97, n = 5, p = 0.001), male width (r = 0.90, Z score = 2.05, n = 5, p = 0.02), moments of inertia (r = 0.67, Z score = 1.81, n = 8, p = 0.03), and precipitation (r = 0.85, Z score = 1.77, n = 5, p = 0.04). There was a marginal linear relationship between copulation duration and the month with the highest number of days with precipitation (r = 0.77, Z score = 1.46, n = 5, p = 0.07). Variance in the polygynandrous reproductive systems of Centrobolus occurred with longer copulations at higher precipitation with wider females having greater moments of inertia and wider males having lower moments of inertia during the height of the rainy season.
