3.2 Lizard body size relationship with resource availability and
seasonality across altitudes
We found that the geographical pattern in the body size of female
lizards is significantly related to changes in net primary productivity
across altitude (Table 3). Specifically, we found that less seasonal
precipitation and limited available resources that characterized
environments at higher altitudes were associated with reduced body size
(Fig. 3a; Table 3). Although seasonal temperature changes were apparent
along altitudes (Fig. 3b), there was no significant relationship between
seasonal temperatures and body size (𝝌2 = 0.068,p = 0.955).
