Fungus knocks a frog down but not out, raising questions about amphibian declines

...hers to speculate that temperature may be a factor affecting the virulence of the fungus and/or the ability of the frogs to survive it. While the Gastric Brooding Frog went extinct, and T. eungellensis suffered its severe decline, yet another species in the area, Litoria lesueuri, was apparently com...

Protein energy profiles offer clues about amyloids
