... an adult-specific translational arrest mechanism that could explain divergent overwintering strategies across development. Chrysemys picta Comparative transcriptomics Reptile Ribosomal protein RNA-seq For almost every animal, oxygen is required for life, but variation in survival time...

...Gary C. Packard; Mary J. Packard SUMMARY Many physiologists believe that hatchling painted turtles ( Chrysemys picta ) provide a remarkable, and possibly unique, example of `natural freeze-tolerance' in an amniotic vertebrate. However, the concept of natural freeze-tolerance in neonatal painted...

...Jon P. Costanzo; Patrick J. Baker; Stephen A. Dinkelacker; Richard E. Lee, Jr SUMMARY Hatchlings of the painted turtle ( Chrysemys picta ) commonly hibernate in their shallow, natal nests. Survival at temperatures below the limit of freeze tolerance (approximately -4°C) apparently depends...

...Gary C. Packard; Mary J. Packard; Leonard L. Mcdaniel ABSTRACT Hatchlings of the North American painted turtle ( Chrysemys picta ) typically spend their first winter of life inside the shallow, subterranean nest where they completed incubation the preceding summer. This facet of their natural...

...Jon P. Costanzo; Jacqueline D. Litzgus; John B. Iverson; Richard E. Lee, JR ABSTRACT Hatchling painted turtles ( Chrysemys picta ) commonly hibernate in shallow, natal nests where winter temperatures may fall below −10 °C. Although hatchlings are moderately freeze-tolerant, they apparently rely...

...Jon P. Costanzo; Jacqueline D. Litzgus; John B. Iverson; Richard E. Lee, JR ABSTRACT Hatchling painted turtles ( Chrysemys picta ) hibernate in their shallow natal nests where temperatures occasionally fall below −10 °C during cold winters. Because the thermal limit of freeze tolerance...
