Spatial Structure Explains Morphological Variation Better Than Climatic Gradients in the South American Rattlesnake (Crotalus durissus)

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
We evaluated whether climatic gradients or spatial structure better explain body size variation in the South American rattlesnake (Crotalus durissus) across its wide geographic range. After explicitly accounting for spatial autocorrelation, climatic variables were not significant predictors of body size in either sex, whereas sex‐specific spatial ...
