Can plants hear?

Yes they can. Marta Zaraska, Scientific American, reports on a new study indicates that “some flora may be capable of sensing sounds, such as the gurgle of water…or the buzzing of insects.” If plants can hear, are they susceptible to noise pollution? Sadly, the answer could be yes.  Zaraska writes that the research “raises questions about whether acoustic pollution affects plants as well as animals.” Monica Gagliano, an evolutionary biologist at the University of Western Australia who worked on the research project said that “[n]oise could block information channels between plants, for example, when they need to warn each other of insects.” So throw out the gas-powered leaf blower and buy yourself a rake. Your flora will thank you.
