Study reveals mechanism used by #TeguLizard to raise own temperature https://phys.org/news/2024-08-reveals-mechanism-tegu-lizard-temperature.html

Mitochondrial function in skeletal muscle contributes to reproductive #endothermy in tegu #lizards https://onlinelibrary.wiley.com/doi/10.1111/apha.14162

During the reproductive season, the muscles of both males and females produced far more #mitochondria... In addition, a mitochondrial protein ANT, known to be involved in a process that generates heat in #birds, was more abundant and more active during the reproductive season.

#Dinosaurs needed to be cold enough that being #warmblooded mattered
Researchers now think dinosaurs that already had some cold tolerance evolved #endothermy, or warm-bloodedness, to adapt when they migrated to regions with cooler temperatures, many dinosaurs from these groups are thought to have been feathered. Feathers can be used to both trap and release heat, allowing dinosaurs to regulate their body temperature in more diverse climates. Birds use feathers same way.

Nesting #dinosaur in the #Arctic : despite constant darkness in winter and cool condition in summer, they were non-migratory species, which raises the question of their possible #endothermy (again). #science #biology #paleontology
