The wood frog has evolved traits that prevent their cells from being damaged when frozen and thawed out. The wood frog has developed various adaptations that allow it to effectively combat prolonged ischemia/anoxia and extreme cellular dehydration. One crucial mechanism utilized by the wood frog is the accumulation of high amounts of glucose ...
The wood frog lives farther north than any other North American amphibian. Glucose in the frog’s cells protects its body from damage caused by freezing, although nearly a third of the body ...
"Ice crystals form beneath the skin and become interspersed among the body's skeletal muscles. During the freeze, the frog's breathing, blood flow, and heartbeat cease. Freezing is made possible by specialized proteins and glucose, which prevent intracellular freezing and dehydration." [8] [9] The wood frog can survive up to 11 days frozen at ...
[1] [2] It is the only ranid frog found in Australia. [3] In Australia, the species is restricted to the rainforest of northern Queensland and the eastern border of Arnhem Land, in the Northern Territory. In Australia, it is usually known as wood frog [4] [5] [6] (though in North America this would refer to Lithobates sylvaticus) or sometimes ...
While some frogs hibernate underground or in water, body temperatures still drop to −5 to −7 °C, causing them to freeze. The wood frog (Lithobates sylvaticus) can withstand repeated freezing, during which about 65% of its extracellular fluid is converted to ice. [57]
