Supporting data: Functional plasticity of the swim bladder as an acoustic organ for communication in a vocal fish
<div> <p>In this study, we show that the swim bladder of male plainfin midshipman fish (<em>Porichthys notatus</em>) exhibits reproductive state-dependent changes in morphology and function for sound production and reception. We quantified swim bladder morphometrics and utilized psuedolandmarking to identify differences in nonreproductive and reproductive male swim bladders. We utilized auditory evoked potential recordings, to measure the auditory sensitivity of saccular hair cells in response to sound pressure levels ranging from 97 - 154 dB re: 1 µPa to determine how the swim bladder contributes to midshipman auditory sensitivity. Finally, we used finite element modeling to explore the frequency response of nonreproductive and reproductive male swim bladders.</p> </div>
High plasticity in marmoset monkey vocal development from infancy to adulthood
<p>The vocal behavior of human infants undergoes dramatic changes across their first year, while becoming increasingly speech-like. Surprisingly, vocal development in nonhuman primates has been assumed to be largely predetermined and completed within the first postnatal months. Contradicting this assumption, we found a dichotomy between the development of call features and vocal sequences in marmoset monkeys suggestive of a role for experience. While changes in call features were related to physical maturation, sequences of and transitions between calls remained flexible until adulthood. As in humans, marmoset vocal behavior developed in stages correlated with motor and social development stages. These findings are evidence for a prolonged phase of plasticity during marmoset vocal development, a crucial primate evolutionary preadaptation for the emergence of vocal learning and speech.</p>

Data from: Vocal plasticity in mallards: multiple signal changes in noise and the evolution of the Lombard effect in birds
Signal plasticity is a building block of complex animal communication systems. A particular form of signal plasticity is the Lombard effect, in which a signaler increases its vocal amplitude in response to an increase in the background noise. The Lombard effect is a basic mechanism for communication in noise that is well-studied in human speech and which has also been reported in other mammals and several bird species. Sometimes, but not always, the Lombard effect is accompanied by additional changes in signal parameters. However, the evolution of the Lombard effect and other related vocal adjustments in birds are still unclear because so far only three major avian clades have been studied. We report the first evidence for the Lombard effect in an anseriform bird, the mallard (Anas platyrhynchos). In association with the Lombard effect, the fifteen ducklings in our experiment also increased the peak frequency of their calls in noise. However, they did not change the duration of call syllables or their call rates as has been found in other bird species. Our findings support the notion that all extant birds use the Lombard effect to solve the common problem of maintaining communication in noise, i.e. it is an ancestral trait shared among all living avian taxa, which means that it has evolved more than 70 million years ago within that group. At the same time, our data suggest that parameter changes associated with the Lombard effect follow more complex patterns, with marked differences between taxa, some of which might be related to proximate constraints..
