Hi Everyone
Just a very quick reply to Heather – why do frogs hang about in ponds in the cold?
The answer is that this is a safe and warm place (relative to the air) which, as long as the water remains oxygenated, is a good place to overwinter.
And frogs have adaptations to this environment – being underwater in winter – though obviously they can stay on land too.
But when the oxygen runs out, underwater is fairly quickly a deadly place for frogs – they can survive probably a maximum of 7 days without oxygen.
So the question is – what type of ponds are most likely to become de-oygenated.
And that’s what we’re working on now – so will keep you posted with results from the Big Pond Thaw and other information.
