Subtropical hibernation in juvenile tegu lizards (Salvator merianae): insights from intestine redox dynamics

Juvenile tegu lizards ( Salvator merianae ) experience gradual and mild temperature changes from autumn to winter in their habitat. This tropical/subtropical reptile enter a state of dormancy, with an 80% reduction in metabolic rate, that remains almost constant during winter. The redox metabolism in non-mammalian vertebrates that hibernate under such distinguished conditions is poorly understood. We analyzed the redox metabolism in the...
