"Frogs and other amphibians rely on the surrounding environment to regulate
their body temperature. On hot days they might seek shade, water or cool spaces
underground. But what if everywhere is too hot?
There is a limit to how much heat amphibians can tolerate. My colleagues and I
wanted to work out how close amphibians are to reaching these limits, globally.
Our new research, published today in
Nature, shows 2% of the world’s
amphibians are already overheating. Even when they have access to shade and
moisture, more than 100 species are struggling to maintain a viable body
temperature.
If global temperatures rise by 4°C, nearly 400 species (or 1 in 13 amphibians)
could be pushed to their limits. However, this assumes access to shade and
water, so it’s probably an underestimate. Habitat loss, drought and disease
will likely make even more amphibians vulnerable to heat stress.
Here is why that matters — and what we can do about it."
