Alaska has two species of frogs. They are the Columbia spotted frog and wood frog. Alaska also is inhabited by two introduced frog species, the Pacific tree frog (also referenced as the Pacific chorus frog), and the red-legged frog. [1] The only species of toad in Alaska is the western toad. [30]
The barking tree frog is known for its loud, strident, barking call. It may also utter a repetitive single-syllable mating call. The calls of the barking tree frog sound like a church bell and have been described as "tonk" and "doonk". [6] It has been known to chorus with other frogs of the same and similar species.

Frogs and amphibians use "anti-freeze" to prevent organ damage while hibernating. Polar bears, foxes, and owls use insulated fur and feathers to protect from the cold conditions.

They are abundant throughout most of the world, occurring on all continents except Antarctica. The true frogs are present in North America, northern South America, Europe, Africa (including Madagascar), and Asia.
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 ...
