Hatchling turtles survive freezing during winter hibernation.
Hatchlings of the painted turtle (Chrysemys picta marginata) are unique as the only reptile and highest vertebrate life form known to tolerate the natural freezing of extracellular body fluids during winter hibernation. Turtles survived frequent exposures to temperatures as low as -6 degrees C to -8 degrees C in their shallow terrestrial nests over the 1987-1988 winter. Hatchlings collected in ...
متن کاملVisualization of Freezing Damage
Freeze-cleaving can be used as a direct probe to examine the ultrastructural alterations of biological material due to freezing. We examined the thesis that at least two factors, which are oppositely dependent upon cooling velocity, determine the survival of cells subjected to freezing. According to this thesis, when cells are cooled at rates exceeding a critical velocity, a decrease in viabili...
متن کاملEvaluation of Freezing Damage in some Pistachio Seedling Rootstocks
A greenhouse experiment was conducted to evaluate the freezing damage in some pistachio rootstocks by ion leakage and pH changes of leaked solution. A factorial experiment was carried out in randomized block designs (RBD) with three factors: Temperature (A) including 4 ̊C, 0 ̊C, -2 ̊C, -4 ̊C, -6 ̊C, Time (B) including 3, 12, 24h , and Rootstock (C) including P. vera cv 'Badami Zarand' (V13) and 'Sar...
متن کاملModeling of Dynamic Behavior and Estimation of Damage Incurred by Self-Centering Rocking Walls
Self-centering rocking walls are known as viable alternatives to typical shear walls, as they provide a number of solutions for eliminating seismic flaws of conventional designs. These rocking walls have a generally positive impact on the seismic behavior of structural systems, but their design makes them susceptible to concrete crushing around their base, which can lead to significantly advers...
متن کاملHow Does Thymine DNA Survive Ultrafast Dimerization Damage?
The photodimerization reaction between the two adjacent thymine bases within a single strand has been the subject of numerous studies due to its potential to induce DNA mutagenesis and possible tumorigenesis in human skin cells. It is well established that the cycloaddition photoreaction takes place on a picosecond time scale along barrierless or low barrier singlet/triplet pathways. However, t...
