Figure 5. Effect of light treatment and sex on the relationship between tibial length and age at maturity.
The relationship between tibial length (mm) at maturity and age (in days) at which male and female spiders reared in the dark at night (0 lux) and light at night (20 lux) treatments completed their final moults. The black line represents the fitted regression line (y = 0.02x + 0.63; Rm2 = 0.49, Rc2 = 0.65) for the overall relationship between tibial length and age at maturation.
