Still Waters Posted November 14, 2012 #1 Share Posted November 14, 2012 Grasshoppers that live in noisy urban environments are having to change their song, a study has found.

They say the insects are forced to increase the volume of the low-frequency sections of their call. http://www.bbc.co.uk/nature/20310262 Link to comment Share on other sites More sharing options...
