Call intensity is a repeatable and dominant acoustic feature determining male call attractiveness in a field cricket
Acoustic signal variation and female preference for different signal components constitute the prerequisite framework to study the mechanisms of sexual selection that shape acoustic communication. Despite several studies of acoustic communication in crickets, information on both male calling song variation in the field and female preference in the same system is lacking for most species. […]
Ambient noise and parental communication of predation risk in tree swallows, Tachycineta bicolor
Ambient noise can mask important acoustic signals used in a variety of communication systems, especially if signals are not adjusted to improve transmission in noise. Nestling birds communicate with their parents using loud begging calls that convey their need for food, but that also attract predators to the nest. Parents can reduce this vulnerability by […]
