Dear MARMAM subscribers,
Our new paper entitled "Mother–pup recognition mechanisms in Australia
sea lion (Neophoca cinerea) using uni‑ and multi‑modal approaches" has
just been published in the special issue "Cognition in marine mammals"
of the journal Animal Cognition.
The paper can be viewed from this link: https://rdcu.be/cPOHl
Authors: Isabelle Charrier, Benjamin Pitcher & Robert Harcourt.
This review covers all the experimental work done these last 16 years on
wild Australian sea lion in collaboration with Macquarie University
researchers (Australia).
*_Abstract:_*
Communication is the process by which one emitter conveys information to
one or several receivers to induce a response (behavioral or
physiological) by the receiver. Communication plays a major role in
various biological functions and may involve signals and cues from
different sensory modalities. Traditionally, investigations of animal
communication focused on a single sensory modality, yet communication is
often multimodal. As these different processes may be quite complex and
therefore difficult to disentangle, one approach is to first study each
sensorial modality separately. With this refined understanding of
individual senses, revealing how they interact becomes possible as the
characteristics and properties of each modality can be accounted for,
making a multimodal approach feasible. Using this framework, researchers
undertook systematic, experimental investigations on mother–pup
recognition processes in a colonial pinniped species, the Australian sea
lion Neophoca cinerea. The research first assessed the abilities of
mothers and pups to identify each other by their voice using playback
experiments. Second, they assessed whether visual cues are used by both
mothers and pups to distinguish them from conspecifics, and/or whether
females discriminate the odor of their filial pup from those from
non-filial pups. Finally, to understand if the information transmitted
by different sensory modalities is analyzed synergistically or if there
is a hierarchy among the sensory modalities, experiments were performed
involving different sensory cues simultaneously. These findings are
discussed with regards to the active space of each sensory cue, and of
the potential enhancements that may arise by assessing information from
different modalities.
