Hyperolius nitidulus live in an environment with a wet season that can be cold and humid, and an extremely hot and dry season. [3] [5] During the hot and dry season the frog is dependent on water therefore it has special adaptations to survive the extreme climate.
Frogs can survive many freeze/thaw events during winter if no more than about 65%-70% of the total body water freezes. Wood frogs have a series of seven amino acid substitutions in the sarco/endoplasmic reticulum Ca 2+ -ATPase 1 (SERCA 1) enzyme ATP binding site that allows this pump to function at lower temperatures relative to less cold ...
Moor frogs are renowned for their ability to tolerate freezing temperatures because most frog species live in hot and humid tropical environments. Many frogs that do live in cold climates will attempt to overwinter in bodies of water because ambient temperatures are moderated by water. In these cases, temperatures only reach a few degrees below ...
The survival of amphibians and reptiles during winter is just as fascinating as the long migration of birds or the winter snooze of woodchucks and chipmunks.
Some frogs such as the wood frog, moor frog, or spring peeper can even survive being frozen. Ice crystals form under the skin and in the body cavity but the essential organs are protected from freezing by a high concentration of glucose. An apparently lifeless, frozen frog can resume respiration and its heartbeat can restart when conditions ...
During times of drought, the clawed frogs can burrow themselves into the mud, becoming dormant for up to a year. [6] Xenopus laevis have been known to survive 15 or more years in the wild and 25–30 years in captivity. [7] They shed their skin every season, and eat their own shed skin.
This photo provided by researchers in December 2022 shows a glass frog, strict leaf dwelling frogs, that sleep, forage, fight, mate, and provide (male) parental care on leaves over tropical streams.
Keeping some or all this material in place until the following growing season, the insects are much more apt to survive the harsh winter conditions with the protection provided. By preserving the ...
