Fig. 4From: Sex-specific innate immunity and ageing in long-lived fresh water turtles (Kinosternon flavescens: Kinosternidae)Egg mass, not clutch size, increases with age in reproducing female K. flavescens. The Y-axis represents residuals from the linear model in Table 3 with age removed from the model. Egg mass residuals = 0.025(Age) – 0.73, R2 = 0.40Back to article page
