Cricket Confusion
Light pollution has been found to make crickets chirp during the day instead of nocturnally, which researchers fear is disrupting their breeding success. Male crickets typically chirp at night as an invitation for females to come and mate with them.
A team from Tel Aviv University and the Open University of Israel found that field crickets exposed to 12 hours of light followed by 12 hours of darkness began to chirp when the lights went out and stopped when the light returned. But those exposed to more light during 24-hour periods lost their natural rhythms and developed a different synchronization with their environment, or they lost all natural rhythm when exposed to constant light.
