Why snakes can go months between meals: A genetic explanation
Snakes may well be one of nature's greatest predators, capable of eating whole deer or even crocodiles, but just as impressive is that they can go months, or even a whole year, without a single meal. And now an international ...
From single queens to mega-colonies: How ant societies are shaped by the environment
A single queen in the tropics; large colonies in deserts; workers with uniform morphology in temperate regions; ant social structures vary according to environmental conditions. This is shown, for the first time at a global ...
