acoustic communication
- Lung-to-ear sound transmission does not improve directional hearing in green treefrogs (Hyla cinerea)
Summary: Contrary to prevailing views on the mechanisms of hearing in frogs, the lung-to-ear pathway for sound transmission does not improve directional hearing in these vociferous vertebrates.
- Echolocating bats exhibit differential amplitude compensation for noise interference at a sub-call level
Summary: Echolocating bats dynamically modulate vocalization amplitude in noise at a sub-call level, demonstrating a high degree of vocal flexibility.
- Auditory evoked potentials of utricular hair cells in the plainfin midshipman, Porichthys notatus
Summary: Utricular potentials of the plainfin midshipman reveal that the utricle is highly sensitive to particle motion in the horizontal plane and is well suited to detect conspecific vocalizations.
- Acoustic behaviour of male European lobsters (Homarus gammarus) during agonistic encounters
Summary: Male European lobsters may use sounds to communicate dominance status during agonistic encounters.
- Whistling is metabolically cheap for communicating bottlenose dolphins (Tursiops truncatus)
Summary: Measurements of the costs of tonal sound production in bottlenose dolphins indicate that whistle communication is very cheap.
- Temporal integration of conflicting directional cues in sound localization
Summary: In grasshoppers, the localization of sounds with ambiguous or conflicting directional cues depends on the magnitude and temporal position of each cue. This gives insight into general principles of directional hearing.
- Auditory evoked potentials of the plainfin midshipman fish (Porichthys notatus): implications for directional hearing
Summary: Auditory evoked responses in reproductively active female midshipman fish are modulated by manipulations of both the saccule and the swim bladder, with implications for mate detection and localization.
- Acoustic crypsis in southern right whale mother–calf pairs: infrequent, low-output calls to avoid predation?
Highlighted Article: Low-output infrequent calls in baleen whale mother–calf pairs may mediate contact between mother and calf, while decreasing the risk of detection by potential predators.
- Sea chordophones make the mysterious /Kwa/ sound: identification of the emitter of the dominant fish sound in Mediterranean seagrass meadows
Summary: Morphological, histological and electrophysiological characterization of the sound apparatus, interpreted with visual and acoustic recordings conducted in semi-natural conditions, identify Scorpaena spp. as the species complex emitting the /Kwa/ sound.
- Acoustic communication in marine shallow waters: testing the acoustic adaptive hypothesis in sand gobies
Summary: The communication system of sand gobies is adapted to enhance sound transmission and reception in Atlantic shallow-water environments, supporting the acoustic adaptive hypothesis.
