Figure 5. Influences of the interactions among age, sex and growth environment on the model. (a) Scatter plots of Δage (year) and chronological age (year) in the female and male datasets. (b) Scatter plots of Δage (year) and chronological age (year) in the captive and wild datasets. The interaction between age and growth environment was significantly explanatory for Δage. (c) Scatter plots of |Δage| (year) and chronological age (year) in the female and male datasets. (d) Scatter plots of |Δage| (year) and chronological age (year) in the captive and wild datasets.
