Methylmercury concentrations of wood frog eggs (geometric mean = 35.9; range: 6.7–77.9 ng/g dry wt) exceeded previous reports for amphibians, including from sites contaminated by industrial sources of Hg. Methylmercury concentrations of adult wood frogs (298.9 ng/g dry wt) were also higher than...
frog before water freezes in the fall. During winter in Alaska, the wood frog freezes so that it looks like a frog-shaped piece of ice. While frozen, the frog stops breathing, its heart stops beating, its blood stops flowing, and it cannot move.However, when spring arrives, the frog’...
scarf down small birds, mammals and snakes with ease, as well as other amphibians and even table scraps and pet food, according to theFlorida Fish and Wildlife Conservation Commission. Their native range stretches from the
The goals of our study were to (1) identify the contribution of environmental variables to the broad-scale distribution of amphibians in drylands of the southwestern United States and Mexico, (2) describe how the habitat suitability of amphibians can potentially respond to a range of climate ...
Our predictions are largely conservative, and probably overestimate the resilience of amphibians to global warming in two main ways. First, we assume that microhabitats such as shaded ground-level substrates, aboveground vegetation and water bodies are available throughout a species’ range, and that...
Framed Antique Frog Engravings of Life Cycle & Metamorphosis A pair of French hand colored copper plate engravings dating from 1749-1780 showing the stages of metamorphosis of frogs. For people interested in Herpetology, the delightful 18th Century engravings are comprised of different frogs, shown in...

Amphibian chytridiomycosis panzootic is ongoing and continuing to have extensive worldwide impact on amphibians. Severity of chytridiomycosis-associated amphibians declines is partly associated with species’ altitudinal ranges. Michoacán state in México harbors 54 amphibian species on a wide range of ...
