The popularity of bioacoustics for threatened species monitoring has surged. Large volumes of acoustic data can be collected autonomously and remotely with minimal human effort. The approach is commonly used to detect cryptic species and, more recently, to estimate abundance or density. However, the potential for conservationrelevant information to be derived from acoustic signatures associated with particular behavior is less well-exploited. Animal vocal behavior can reveal important information about critical life history events. In this study, we argue that the overlap of the disciplines of bioacoustics, vocal communication, and conservation behavior-thus, "acoustic conservation behavior"-has much to offer threatened species monitoring.In particular, vocalizations can serve as indicators of behavioral states and contexts that provide insight into populations as it relates to their conservation. We explore the information available from monitoring species' vocalizations that relate to reproduction and recruitment, alarm and defense, and social behavior, and how this information could translate into potential conservation benefits. While there are still challenges to processing acoustic data, we conclude that acoustic conservation behavior may improve threatened species monitoring where vocalizations reveal behaviors that are informative for management and decision-making.

“…It is important to note that while many studies have found a relationship between fundamental frequency and body size in several species (e.g., Bowling et al, 2017;Charlton & Reby, 2016;Gingras, Boeckle, Herbst, & Fitch, 2013;Hauser, 1993;Wallschläger, 1980), others have not (e.g., Patel, Mulder, & Cardoso, 2010;Rendall, Kollias, Ney, & Lloyd, 2005;Sullivan, 1984). As noted by Bowling et al (2017), a relevant factor seems to be the range in body sizes 16 The authors theorize that two separate, but potentially related, processes may be at work.…”

Five mechanisms of sound symbolic association

2017

Sound symbolism refers to an association between phonemes and stimuli containing particular perceptual and/or semantic elements (e.g., objects of a certain size or shape). Some of the best-known examples include the mil/mal effect (Sapir, Journal of Experimental Psychology, 12, 225-239, 1929) and the maluma/takete effect (Köhler, 1929). Interest in this topic has been on the rise within psychology, and studies have demonstrated that sound symbolic effects are relevant for many facets of cognition, including language, action, memory, and categorization. Sound symbolism also provides a mechanism by which words' forms can have nonarbitrary, iconic relationships with their meanings. Although various proposals have been put forth for how phonetic features (both acoustic and articulatory) come to be associated with stimuli, there is as yet no generally agreed-upon explanation. We review five proposals: statistical co-occurrence between phonetic features and associated stimuli in the environment, a shared property among phonetic features and stimuli; neural factors; species-general, evolved associations; and patterns extracted from language. We identify a number of outstanding questions that need to be addressed on this topic and suggest next steps for the field.

“…These findings are highly relevant for modeling purposes. However, extending them to bioacoustics and voice science seems to require additional investigation because the frequency range examined to assess the effect of the freezing process (0.01-15 Hz) was well below the range of f o of most mammalian vocalizations (see, for example, the results for some primates and carnivores reported by Bowling et al (2017)). …”

The study of sound production mechanisms is a crucial, yet understudied, aspect of vocal communication research in vertebrates. In excised larynx experimentation (ELE), phonation is simulated ex vivo by forcing air through a larynx specimen mounted on a laboratory bench. The method provides unique insights into vocal production and allows inference of in vivo conditions. Here, we provide a historical overview of how this technique has been implemented, from antiquity to current state-of-theart setups. We review the advances made by applying ELE to human voice and biophysics research. We then highlight the promising research output resulting from ELE in animal bioacoustics, a research field that has largely overlooked the use of this method until very recently, but is now increasingly relying on this tool. We continue by discussing the limitations of ELE, depending on the focus of investigation. Finally, we suggest how this approach should be implemented and can be applied to various research questions. We conclude by underlining the value that ELE contributes to the comprehension of human voice as well as mammalian and avian vocal communication within an interdisciplinary approach.
