We propose Freeze Endurance (Fend) as a new measure of the ability of amphibians to tolerate internal freezing, allowing integration of time and temperature to describe each freeze event. Use of freeze endurance as a descriptor allows direct comparison between individuals, populations, and species, and may be scaled by body size, or other characteristics, to determine if abilities to survive freezing are significantly different between groups. Thermal limit examinations have long suffered from lack of comparability between publications due to differing endpoints, measurements, equipment, and organism availability, despite the value of information yielded by such studies to understanding …
