The grasshopper is a coffee creature…according to Aesop's fables. But in real life, grasshoppers can have a lot to worry about. For example, grasshoppers get quite anxious when they know there's a deadly snider about, and it puts them off their food. Since their food is grass, nervous grasshoppers leave more grass intact to perform photosynthesis, burning sunlight and carbon dioxide into plant food. More CO2 in these grasses and their roots means less CO2 in the air. That's according to a new paper published in Proceedings of the National Academy of Sciences. Yale researchers tracked CO2 as it cycled through Plexi glass cages containing just grass, grass and grasshoppers, or brass , grasshoppers and spiders. Grasses stored 1.4 times as much carbon with spiders about than when grasshoppers were allowed to roam unmolested. That's even better than when there were no grasshoppers at all because nervous grasshopper grazing did little damage but spurred greener growth. In other worlds , spiders protect the climate, just by being spiders and scaring grasshoppers. Similar results may also prove true in ecosystems with larger predators, whether wolves and caribou or lions and zebras. Keeping predictors around may be another way to combat climate change.
