Changes in overall morphology of E. rowelli during decay. Change (%) is calculated as original length minus decayed length, divided by original length. Dotted lines join mean values; solid lines show linear regressions. (a) Change in the body length; R2 = 0.021, F = 0.881, df = 1,39, p = 0.354. (b) Change in body width; measurements were taken between the 7th and 8th limb pair, across the outer cuticle (open circles) and detached epidermis (solid); outer R2 = 0.392, F = 27.777, df = 1,43, p <0.0001; inner R2 = 0.122, F = 4.304, df = 1,31, p = 0.046. (c) Change in limb length (seventh pair); measurements were taken from base of the terminal pad to the junction between limb and trunk; R2 = 0.148, F = 4.003, df = 1,23, p = 0.057. (d) Change in the limb width (seventh pair); measurements were taken at the widest point of the limb, across the outer cuticle (open circles) and detached epidermis (solid); outer R2 = 0.003, F =0.131, df = 1,40, p = 0.719; inner R2 = 0.181, F = 5.966, df = 1,27, p = 0.021. F tests are for significance of slope of regression.
