Japanese researchers from Nagoya University have revealed new aspects of the interaction between mast plants or mass seeding plants, i.e. plants that spread their seeds at once like Sasa bamboo and field mice. Their research reveals that mouse behavior (which varies between species, and varies according to environmental conditions and seasons) plays a crucial role in seed dispersal and ecosystem health in forests, and challenges existing theories about seed storage and consumption.

Each plant and each type of distress has a characteristic, recognizable sound. The sounds of the plants sound like clicks, like popcorn, at a volume similar to human speech but at frequencies above the human hearing range, and they are made
