Plants Can Hear Themselves Being Eaten
Now what are vegans going to eat!?
I guess the bigger questions now is do the plants care and can they feel it?
Full story at I Fucking Love Science.com:
A small, flowering plant called Arabidopsis thaliana can hear the vibrations that caterpillars trigger when they chew on its leaves. According to a new study, the plants can hear danger loud and clear, and they respond by launching a chemical defense.
In this first example of plants responding to ecologically relevant vibrational sounds (i.e. predation), Cocroft and Mizzou’s Heidi Appel combined audio and chemical analyses. First, they placed a tiny piece of reflective tape on a leaf; that way, using a laser beam, they can measure the leaf’s movements as the caterpillar munches.
