When spring gets here, a lot of wood frogs awaken from their icy rest with something on their mind: sex. Males discover a pond or short-lived vernal swimming pool and contact us to women with noises “practically like a quacking duck,” states Dartmouth College’s Ryan Calsbeek, a biology teacher who studies amphibians’ sex lives. As more males take part, the cacophony of croaks can be heard throughout the forest.

Hearing the teasers from the ponds around them, women hop towards the croaks they discover most sexy. In a current research study utilizing an innovative acoustic electronic camera, Calsbeek figured out that female wood frogs, like numerous people, can’t withstand deep, husky voices. Such croaks tend to come from big frogs– once a woman is tempted to a
