WebMay 11, 2010 · The focus of this study is the interplay between sociality and thermoregulation in neonatal bearded dragons. Aggregations may reflect social tendencies or may exist as a behavioral mechanism involved in modulating heating and cooling rates [6], [29], [35], suggesting them to be an adaptive response to variable climatic environments. WebAnimal coloration has multiple functions including thermoregulation, camouflage, and social signaling, and the requirements of each function may sometimes conflict. Many terrestrial ectotherms accommodate the multiple functions of color through color change.
