  • In recent years, epigenetic regulation has become heavily implicated in stress adaptation of many animals, including supporting freeze tolerance of the wood frog ( Rana sylvatica ). (nih.gov)
  • Multiple, interactive stresses, in addition to diminished cryoprotectant levels, contribute to the reduced capacity for freeze tolerance in posthibernal frogs. (hindawi.com)
  • Elucidation of these mechanisms will require comprehensive study of organisms for which the fundamental adaptations of freeze tolerance are reasonably well known. (hindawi.com)
  • The relatively robust freeze tolerance exhibited by certain woodland frogs is associated with their ability to accrue high concentrations of the cryoprotectants, glucose, and/or glycerol, which during freezing are mobilized from glycogen in the liver. (hindawi.com)
  • Because the hepatic glycogen store is substantially reduced following hibernation and mating, spring frogs can accrue only modest amounts of these agents, and this difference purportedly is the cause of their reduced freeze tolerance [ 4 - 8 ]. (hindawi.com)
  • It was recently reported [ 9 ] that some freeze-tolerant frogs also use urea as a cryoprotectant, but whether variation in urea levels also contributes to seasonality of freeze tolerance has not been investigated. (hindawi.com)
  • Aside from cryoprotectant levels, freeze-tolerance capacity is influenced by physiological factors such as the osmotic activity of body fluids, hydration state of the tissues, and distribution of the water between "bulk" and "bound" fractions. (hindawi.com)
  • Investigation of the putative roles of these factors in the seasonality of freeze tolerance in vertebrates has been hampered by the rather modest limits for freezing survival in these organisms, as even fully cold-hardened frogs survive freezing to temperatures only as low as −4°C to −6°C. Recently, however, extreme freeze tolerance was documented in wood frogs ( Rana sylvatica ) endemic to Interior Alaska [ 10 ]. (hindawi.com)
  • Exceptional freeze tolerance was also attributed to an unusually large proportion of body water that was "bound" (i.e., unfreezable by virtue of its close association with macromolecules). (hindawi.com)
  • Our present aim was to characterize freeze-tolerance capacity and physiological aspects of the freezing adaptation in a northern population of R. sylvatica shortly following their emergence from hibernation. (hindawi.com)

  • Whereas winter frogs can survive freezing at temperatures at least as low as −16°C, the lower limit of tolerance for spring frogs was between −2.5°C and −5°C. Spring frogs had comparatively low levels of the urea in blood plasma, liver, heart, brain, and skeletal muscle, as well as a smaller hepatic reserve of glycogen, which is converted to glucose after freezing begins.
