The signal in noise: Acoustic information for soundscape orientation in two North American tree frogs

Lay Summary Information conveyed by the timing and temporal structure of calls embedded in sounds of breeding choruses is necessary for eliciting orientation in treefrogs. In contrast, information based on emergent acoustic properties arising from the collective mixture of calls constituting the chorus is not enough. Orientation based on the timing and temporal properties of the actual calls composing choruses could limit the distances over which female frogs could use sound to orient toward and localize breeding aggregations.
