Researchers find Antarctic penguin breeding is heating up sooner, and that’s a problem

"Penguins are changing the time at which they're breeding at a record speed, faster than any other vertebrate," said lead author Ignacio Juarez Martinez, a biologist at Oxford University in the United Kingdom. "And this is important because the time at which you breed needs to coincide with the time with most resources in the environment and this is mostly food for your chicks so they have enough to grow.''
