Overview

Randomized trial examines cranial soft tissue scaling in geckos, highlighting evolutionary implications.

Key Points

  • The study aims to explore the scaling patterns of cranial soft tissues in geckos in relation to their body sizes.
  • Used three-dimensional volumetric data from DiceCT and μCT scans.
  • Conducted phylogenetic comparative analyses using phylogenetic RMA regression.
  • Evaluated scaling against two size proxies: snout-vent length and cranial size index.
  • Cranial soft tissues scale non-uniformly; head volume is approximately isometric.
  • Brain volume exhibits negative allometry, while jaw adductor muscle volume shows positive allometry.
  • Functional partitioning reveals temporal and palatal jaw groups drive positive allometry, whereas protractor muscles are approximately isometric.
