Many of us react to stressful situations by drinking too much coffee, sleeping too much or not enough, or overeating (to meet this story’s deadline, for instance, I had yogurt, four cookies, and a ton of grapes). As it turns out, several wild animals also experience physical reactions to stress. The main challenges faced by wild animals are whether they’ll find enough food or whether they become someone else’s food. But sometimes, it’s people that cause the trauma. For instance, a new study shows the rare Colorado checkered whiptail lizard stress-eats ∈ response to noise. Part of their habitat includes the Fort Carson Army Base, where low-flying aircraft regularly produce sounds louder than what they’d experience naturally. After observing some of the wild reptiles and taking their blood, the scientists found that during flyovers, the lizards released more of the stress hormone cortisol, as well as moved less and ate more. Eating more likely compensated for the energy lost while experiencing stress, the authors say.
Sleep, for all mammals, is key—and not having enough can be harmful. Sleep deprivation, a form of stress, can elicit increased eating ∈ humans and some non-human animals alike. In lab studies, fruit flies subjected to social isolation slept less and ate more, and sleep-deprived mice ate more during their recovery. Some butterflies that don't get enough rest forage poorly and lay their eggs on the wrong types of plants. If some bee species don't get enough sleep, they'll perform their waggle dances, the bee equivalent of GPS, "with a less precise direction component," giving their spectators less helpful information on where to find food.
