About this video, from Turtle Journal in the USA:
Wood frogs (Rana sylvatica) are typically the first amphibians Turtle Journal encounters each March. No difference this year. Last week, when we checked for signs of spring emergence in wetlands surrounding the abandoned Goldwitz cranberry bog in Marion, the only peep we heard was a single wood frog. Deep in the swamp, a plaintive, unanswered call echoed through the brush.
A world without frogs? These scientists can’t imagine it — and are doing something about it: here.
