- 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.
- Vocal differentiation parallels development of auditory saccular sensitivity in a highly soniferous fish
Highlighted Article: Vocal differentiation and parallel development between vocal–motor control and saccular sensitivity in toadfish.
- Decision making and preferences for acoustic signals in choice situations by female crickets
Summary: Choice behaviour of female crickets can be explained by a simple comparison between auditory input from both sides and is reliably predicted by a computational model based on pattern and intensity cues.
- Effects of signal features and background noise on distance cue discrimination by a songbird
Summary: Experiments with trained animals help understanding of how song birds perceive signals in their natural environment. We tested how background noise affects the perception of acoustic cues that aid assessing the distance of a sound source.
