Heterospecific alarm call recognition in a non-vocal reptile.
The ability to recognize and respond to the alarm calls of heterospecifics has previously been described only in species with vocal communication. Here we provide evidence that a non-vocal reptile, the Galápagos marine iguana (Amblyrhynchus cristatus), can eavesdrop on the alarm call of the Galápagos mockingbird (Nesomimus parvulus) and respond with anti-predator behaviour. Eavesdropping on com...
متن کاملAuditory Plasticity: Vocal Output Shapes Auditory Cortex
Studies in humans and songbirds have revealed a close link between vocal output and hearing. Now experiments in marmosets have shown that self-generated vocalizations can modulate the activity of neurons in the auditory cortex and even remodel their response properties.
متن کاملOn the evolution of noise-dependent vocal plasticity in birds.
Signal plasticity is considered an important step in the evolution of animal communication. In acoustic communication, signal transmission is often constrained by background noise. One adaptation to evade acoustic signal masking is the Lombard effect, in which an animal increases its vocal amplitude in response to an increase in background noise. This form of signal plasticity has been found in...
متن کاملSong-evoked inhibition and its role in vocal plasticity
cell types, one that innervates the song motor nucleus RA, and the other that innervates the basal ganglia homologue area X. Area X, the thalamic nucleus DLM and the anterior telencephalic nucleus LMAN form the anterior forebrain pathway (AFP; gray), which is implicated in auditory feedback and song perception, and which is essential to audition-guided vocal plasticity in juvenile and adult bir...
متن کاملBiomechanical control of vocal plasticity in an echolocating bat.
Many animal species adjust the spectral composition of their acoustic signals to variable environments. However, the physiological foundation of such spectral plasticity is often unclear. The source-filter theory of sound production, initially established for human speech, applies to vocalizations in birds and mammals. According to this theory, adjusting the spectral structure of vocalizations ...
