Variation in signal complexity is common among different species. Understanding why some
species have evolved extensive call complexity can offer insight into the evolution of …

Vocal Communication plays a crucial role in survival and reproductive success in most
amphibian species. Although amphibian communication sounds are often complex …

Background: Contemporary bioacoustics is an interdisciplinary science by combining
biology and ecology with acoustics. Through the mutual penetration and integration of …

The effective production of acoustic signals is critically important for intraspecific
communication in vocal animals; however, it is also highly time-consuming, energetically …

The ability to discriminate species and recognize individuals is crucial for reproductive
success and/or survival in most animals. However, the temporal order and neural …

Background Animal vocal signals encode very important information for communication
during which the importance of temporal and spectral characteristics of vocalizations is …

Sex differences in both vocalization and auditory processing have been commonly found in
vocal animals, although the underlying neural mechanisms associated with sexual …

Seasonal changes in the structure and function of the vertebrate brain have been described
in many species, particularly in seasonal breeders. However, it remains unclear whether …

The characteristics of acoustic signals co-evolve with preferences of the auditory sensory
system. However, how the brain perceives call variations and whether it can reveal …

Sex differences in vocalization have been commonly found in vocal animals. It remains
unclear, however, how animals perceive and discriminate these differences. The amplitudes …
