To express your interest in participating and submitting an abstract, please
send an e-mail with the title of your contribution to the organizers before
April, 26th.
Symposium description: Animal vocalisations can encode a variety of
information, including physical features of the signaler. In particular,
acoustic allometry investigates how vocal features scale with body dimensions
of an animal. Intuitively, larger animals may have larger vocal organs, hence
sounding bigger, within or across species. The study of acoustic allometry is a
crucial step to verify this assumption and identify outliers to this
expectation. Ultimately, it allows to better understand sound production and
evolutionary history of specific vocalisations or acoustic features. Over the
last decades, the study of allometry has flourished. However, although the
relationship between body size and acoustic features of vocalisations has been
documented in many mammals, it deserves further investigations across other
taxa. A purpose of our symposium is to connect and summarise findings of
allometry across multiple dimensions and perspectives. First, we will focus on
comparison across species, with contributions potentially focusing on any
animal, as long as this relates to allometry. Second, we will examine the link
between producing and perceiving sounds that contain acoustic allometric
features, both within and between species. Third, we hope to attract research
work documenting an absence of acoustic allometry to ask which socio-ecological
and evolutionary factors may lead a species to deviate from a widespread
allometric pattern. Fourth, inspired by Tinbergen’s approach, we aim to present
contributions dealing with allometry from a functional, mechanistic,
developmental and phylogenetic perspective. Indeed, allometric mechanisms are
different depending on the taxa considered (e.g. while some birds show tracheal
elongation, some mammals have laryngeal or vocal tract hypertrophy). Moreover,
the evolutionary bases for acoustic allometric rules are diverse (e.g. sexual
selection, agonistic interaction, species-specific recognition) and
interconnected with other questions such as encoding of species, population or
individual identity information in vocalisations. Fifth, we will explore new
approaches and directions to allometry, such as its connection to vocal
learning, size exaggeration, and human non-linguistic vocalisations. Finally,
we will focus on potentially promising applications of this research strand,
including livestock and conservation, with the objective to make use of
estimating the size of an individual towards minimized disturbance.
