... freeze avoidance through supercooling or freeze tolerance. Supercooling, a metastable state in which body fluids remain liquid below the equilibrium freezing/melting point, is promoted by physiological responses that protect against chilling injury and by anatomical and behavioral traits that limit risk...

... by a 20 h exposure to sub-zero temperatures in a supercooling state or after thawing. In parallel, we show an increase in the co-activators,peroxisome proliferator-activated receptor γ coactivator-1α(PGC-1α) and peroxisome proliferator-activated receptors (PPAR), mRNA expression, suggesting...

...-wintering, termed cryoprotective dehydration, has been described for several freeze-intolerant soil invertebrates( Holmstrup, 1992 ; Holmstrup and Westh, 1994 ; Holmstrup and Sømme,1998 ; Holmstrup et al.,2002 ). In this strategy, supercooled invertebrates with high integumental permeability dehydrate...

... freezing and to sustain a state of supercooling. As temperature declines below 0°C, however, the heart of an unfrozen turtle beats progressively slower, the diminished perfusion of peripheral tissues with blood induces a functional hypoxia, and anaerobic glycolysis assumes ever greater importance...

... into body compartments from frozen soil. In the absence of a nucleating agent or a crystal of ice to `catalyze'the transformation of water from liquid to solid, the bodily fluids remain in a supercooled, liquid state. The supercooled animals nonetheless face physiological challenges, most notably...

... on their ability to remain supercooled, and, whereas previous studies have reported that supercooling capacity improves markedly with cold acclimation, the mechanistic basis for this change is incompletely understood. We report that the crystallization temperature ( T c ) of recently hatched(summer) turtles...
