The wood frog has a complex lifecycle that depends on multiple habitats, damp lowlands, and adjacent woodlands. Their habitat conservation is, therefore, complex, requiring integrated, landscape-scale preservation. [1] Wood frog development in the tadpole stage is known to be negatively affected by road salt contaminating freshwater ecosystems ...
In winter regions that do not have permafrost, the subnivean zone maintains a temperature of close to 32 °F (0 °C) regardless of the temperature above the snow cover, once the snow cover has reached a depth of six inches (15 cm) or more. The sinuous tunnels left by these small mammals can be seen from above when the snow melts to the final ...
Although these frogs can swallow animals almost half their size, they sometimes attempt to eat things larger than they are. Their teeth, as well as bony projections in the front of the jaw, can make it difficult for them to release prey after taking it in their mouth, in some cases leading to death by choking.
Other animals able to survive long periods with very little or no oxygen include goldfish, red-eared sliders, wood frogs, and bar-headed geese. [36] The ability to survive hypoxic or anoxic conditions is not closely related to endotherm hibernation. Some animals can literally survive winter by freezing.
Water-holding frogs are ectothermic, [8] meaning they depend on external sources of body heat. Aestivation is a behaviour characteristic of water holding frogs. It is similar to how other animals hibernate, except it takes place during summer as opposed to winter when weather conditions are hot and dry. This behaviour is a response to high ...

A rain of animals is a rare meteorological phenomenon in which flightless animals fall from the sky. Such occurrences have been reported in many countries throughout history. [ 1 ] One hypothesis is that tornadic waterspouts sometimes pick up creatures such as fish or frogs, and carry them for up to several miles.
Cascades frogs lay their eggs May 20 through July 10, depending on when the snow melts and creates ponds in which the eggs are laid. First, egg masses are deposited in comparatively warm water along gradually sloping shorelines, often over soft substrates protected from severe wave action.
