acoustic communication
- 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.
- Frequency channel-dependent selectivity for temporal call characteristics in gray treefrogs, Hyla versicolor
Summary: Nervous systems process and integrate information from multiple components of complex signals. Frogs process acoustic signals in two different frequency channels, which vary in their temporal sensitivity.
- Functional relevance of acoustic tracheal design in directional hearing in crickets
Summary: Crickets use a modified tracheal system that couples their two ears for sound localization. Yet, the most elaborate of these systems does not provide better directionality compared with more simple forms.
- Better late than never: effective air-borne hearing of toads delayed by late maturation of the tympanic middle ear structures
Summary: Late maturation of tympanic middle ear structures in toads causes reduced sensitivity to sounds in free-living, post-metamorphic animals.
