Any signal must get from a sender to a receiver if information is to be transmitted. In the case
of bird song, the acoustic properties of the habitat may hinder this being achieved. However …

Many animals rely on long-range communication for species recognition, mate selection and
territorial defense, but background noise from the environment can constrain their …

Although field-collected recordings typically contain multiple simultaneously vocalizing birds
of different species, acoustic species classification in this setting has received little study so …

A universal challenge faced by animal species is the need to communicate effectively
against a backdrop of heterospecific signals. It is often assumed that this need results in …

Soundscape mapping provides a unique perspective to explain the complicated spatial-
temporal change of bird activities in urban forests. Most studies of soundscapes have used …

Bird species sing different songs and as a result rarely breed with each other. Species are
not static but can shift in acoustic and morphological space, yet maintain their …

Natural selection is known to produce convergent phenotypes through mimicry or ecological
adaptation. It has also been proposed that social selection—ie, selection exerted by social …

In species-rich biomes such as tropical rainforests, the efficiency of intraspecific acoustic
communication will strongly depend on the degree of signal overlap. Signal interference …

Monitoring biodiversity and assessing the impact of human activities using acoustics is a
promising area in the field of urban ecology. Previous studies on urban biodiversity using …

Many social animals use long-distance signals to attract mates and defend territories. They
face the twin challenges of discriminating between species to identify conspecific mates, and …
