The species richness and calling activity of an anuran community inhabiting an agricultural
wetland area at 1645 m asl near Butare, Rwanda, was assessed using visual and acoustic …

Sound is an inherent component of the environment that provides conditions and
information necessary for many animal activities. Soniferous species require specific …

Abstract Asian Mountain Toads (Ophryophryne) are a poorly known genus of mostly small-
sized anurans from southeastern China and Indochina. To shed light on the systematics …

Acoustic signals are constrained by background noise. Visual signals are an alternative or
complementary communication mode in noisy habitats and play a fundamental role in …

Humans categorize unwanted sounds in the environment as noise. Consequently, noise is
associated with negative human and ecological values, especially when it is derived from an …

Physical aspects of anurans constrain sound production, and noisy habitats pose a
challenge to signal recognition and detection. Habitat acoustics impose selection on anuran …

Differences in advertisement calls and calling sites are important mechanisms that regulate
interactions in anuran assemblages. Individuals might have preferences for ranges of …

Long-range acoustic signals are subject to a variety of evolutionary pressures, such as
sexual selection, species recognition, body-size constraints, physiological constraints, and …

Environmental noise can be an important selective force modulating signal evolution in
species with acoustic communication. Many anuran species breed alongside streams; …

According to the acoustic adaptation hypothesis, abiotic noise generated by streams should
promote the evolution of high‐pitched signals in acoustically communicating animals. The …
