Conclusion
In sum, we showed that the body sizes of female lizards were smaller at
high altitudes due to colder and drier climatic conditions, which is a
reversal of Bergmann’s rule. Further, we showed that the geographical
patterns of body sizes within populations of lizards are largely
influenced by the variation of climatic and seasonality along
altitudinal clines. As expected, resource availability in highly
seasonal environments such as rainfall along altitudinal clines
significantly influenced the body’s variations within populations of
female lizards, suggesting that the variations in the geographic
patterns of female lizards’ body sizes may be largely driven by
multifarious environments as adaptive plasticity for organisms to
possibly buffer physiological costs along geographic clines.
