The wood frog, Rana sylvatica, has numerous adaptations that allow it to survive freezing of up to 65% of its total body water during the winter. Such adaptations have been found to include the expression of novel freeze responsive genes that are thought to be important for adaptation and ...

(to 71°N) by the Siberian wood frog (Rana amurensis) was facilitated by a unique adaptation, the ability to survive extreme hypoxia — and probably anoxia — in waterbodies during overwintering. The oxygen content in the overwintering waterbodies that we have studied in different parts of ...
This study employed the use of immunoblotting to examine response of a potent cell cycle and apoptosis regulator, known as the Janus kinase-signal transducer and activator of transcription (JAK-STAT) signaling pathway, to freezing and thawing in the liver and skin of the wood frog. This ...
One of the most extreme examples of environmental stress adaptation is used by the North American wood frog Rana sylvatica (recently reclassified as Lithobates sylvaticus) that undergoes whole body freezing in their terrestrial wintering sites (Schmid 1982). The ability of wood frogs to tolerate ...
When temperatures are cold, a wood frog digs down a few inches beneath the leaves on the forest floor. As the outdoor temperature decreases, the frog' s skin freezes. For a human this would result in cold injury, or the freezing of body tissues, but the wood f...
