|
Box turtles (Terrapene carolina, T. ornata), at ~500 g in mass, are both the largest known freeze-tolerant animals and the only adult turtles that display this adaptation (Storey and Storey, 1992). However, hatchlings of several northern turtle species that spend their first winter on land are freeze tolerant including painted turtles (Chrysemys picta), Blanding’s turtles (Emydoidea blandingii), diamondback terrapins (Malaclemys terrapin), and ornate box turtles (T. ornata) (Storey and Storey, 1992; Costanzo et al., 2008). Hatchlings of some other species rely instead on a capacity to supercool and resist ice nucleation; the map turtle, Graptemys geographica, is a good example (Baker et al., 2003). Interestingly, both cold hardiness strategies have been reported for painted turtle populations from different geographic locales; some populations of C. picta show well-developed freeze tolerance whereas others show extensive supercooling (to - 10°C or lower) (Storey, 2006; Costanzo et al., 2008).
