Kids in the Pool

The runner-up in the “biodiversity under threat” category, this photo depicts a male wood frog clinging to an egg mass. Wood frogs are known for being able to survive winters by freezing themselves. And though their populations aren’t in serious danger currently, many of the forested habitats they occupy throughout North America are being threatened by urbanization, while climate change may be harming the survival of their eggs, which are often laid in temporary puddles or pools of water.
