The costs of chronic noise exposure for terrestrial organisms
Growth in transportation networks, resource extraction, motorized recreation and urban development is responsible for chronic noise exposure in most terrestrial areas, including remote wilderness sites. Increased noise levels reduce the distance and area over which acoustic signals can be perceived by animals. Here, we review a broad range of findings that indicate the potential severity […]
Acoustic Interaction in Animal Groups: Signaling in Noisy and Social Contexts
It has long been known that individuals of many species vocally communicate with one another in noisy environments and in rich contexts of social interaction. It has recently become clear that researchers interested in understanding acoustic communication in animal groups must study vocal signaling in these noisy and socially complex settings. Furthermore, recent methodological advances […]
Estimating the distance to a source of sound: mechanisms and adaptations for long-range communication
Acoustic signals are used for long-range communication in many animals from insects to birds and mammals. Long-range signals are used primarily by males to advertise and defend their home ranges or territories or to attract mates. During transmission over long distances, the structure of signals becomes progressively degraded. At the position at which a receiver […]
