- Selective attention in peacocks during assessment of rival males
Summary: Peacocks selectively direct their attention toward the lower display regions of the train during rival assessment in a pattern similar to how peahens direct their attention toward potential mating partners.
- Evolution of vocal patterns: tuning hindbrain circuits during species divergence
Summary: Courtship song dynamics arise from finely tuned motor circuits. Alterations in the activity of a key nucleus of the hindbrain vocal circuit accompany call pattern divergence during speciation in African clawed frogs.
- Unusual sound production mechanism in the triggerfish Rhinecanthus aculeatus (Balistidae)
Summary: Rhinecanthus aculeatus produce sounds by alternate sweeping movements of pectoral fins which push the scutes. The first part of each sound pulse cycle corresponds to inward buckling of the scutes and the second corresponds to passive recoil of the swimbladder wall.
- Mechanosensory signaling as a potential mode of communication during social interactions in fishes
Summary: Many fish social behaviors generate water movements that are detectable by the lateral line system of nearby conspecifics, suggesting that mechanosensory signaling may be an important mode of communication during social interactions such as reproduction, aggression and parental care.
- Modelling colour constancy in fish: implications for vision and signalling in water
Summary: Models of light propagation in water and visual mechanisms show how changes in depth and distance alter visible spectra, and predict the consequences for fish colour vision and colour signals.
- Developmental changes of cognitive vocal control in monkeys
Highlighted Article: Monkeys reliably vocalize on command during juvenile periods, but discontinue this behavior in adulthood. This greater vocal flexibility of monkeys early in ontogeny supports the neoteny hypothesis in human evolution.
- Effects of estradiol on neural responses to social signals in female túngara frogs
Summary: Estradiol changes the basal activity of the auditory midbrain and limbic forebrain of female túngara frogs, and modifies the response of the preoptic area to mating calls.
- Sound pressure enhances the hearing sensitivity of Chaetodon butterflyfishes on noisy coral reefs
Summary: Butterflyfish detect sound pressure to enhance hearing and aid social communication in a noisy environment.
- Evolutionary adaptations for the temporal processing of natural sounds by the anuran peripheral auditory system
Summary: Peripheral auditory systems of treefrogs are evolutionarily adapted to process the temporal fluctuations inherent in conspecific communication signals.
