Abstract

Freeze tolerance is the ability of an organism to survive from water in portions of its body freezing due to molecular, biochemical, physiological, or a combination of these adaptations. Within squamates, freeze tolerance is documented or suspected, based on observations of freezing survival in only five species. I report an observation of survival of short-term freezing in the eastern fence lizard, Sceloporus undulatus.

La tolerancia al congelamiento es definida como la habilidad de un organismo para sobrevivir ileso al congelamiento del agua en partes de su cuerpo, debido a una o varias adaptaciones moleculares, bioquímicas, y fisiológicas. En Squamata, la tolerancia al congelamiento ha sido documentada o sospechada únicamente en cinco especies, basado en observaciones de sobrevivencia al congelamiento. Reporto una observación de tolerancia al congelamiento a corto plazo en la lagartija escamosa de pradera, Sceloporus undulatus.
