Figure 6
Variation in female life histories along climatic gradients. Depicted are the results of post-hoc ANCOVAs (residuals, corrected for other model terms). (a) As climate-related PC1 increases, body fat content showed a slight decrease in female G. affinis, while the trends differed slightly between coastal and inland populations. Females from inland populations increased (b) RA towards the south, while the trend was reversed in coastal populations. (c) A similar (but weak) trend was observed for embryo lean weight. Overall, this led to a pattern where females increased (d) RA and (h) embryo lean weight, but decreased (e) body fat content and (g) somatic lean weight with increasing values of climatic PC1. With increasing values of climate-related PC2, broods consisted of (i) more but (h and j) smaller embryos.
