A stressed grasshopper's body has less nitrogen because of the change in its diet, and microbes in the soil rely on that nitrogen to break down other material. Without the nitrogen from the grasshopper, plant parts will be broken down by microbes more slowly than usual, and without that help from the microbes, new plants will struggle to grow too. So what freaks out grasshoppers? Well, getting eaten is pretty high on the list, and that's what researchers at the Hebrew University of Jerusalem and Yale used to test this idea. They split up two groups of grasshoppers; the unlucky group...
