The evolution of primate vocal communication: a social route

open access: yesRevue de Primatologie, 2023
There is no doubt that different factors determine the evolutionary trajectory of a species' communication abilities. Beyond habitat, social life is likely a selection pressure.

Middle Spotted Woodpecker territory owners distinguish between stranger and familiar floaters based on their vocal characteristics

open access: yesThe European Zoological Journal, 2020
Acoustic communication is an important part of behaviour in many bird taxa. In most woodpecker species drumming functions in mate attraction and territory defence.

Variación individual e indicios de variación geográfica en el canto territorial del chucao (Scelorchilus rubecula) en el centro-sur de Chile

open access: yesGayana, 2020
We evaluated the individual and geographic variation in the territorial songs of five populations of Scelorchilus rubecula. The results suggest individually consistency in songs and vocal variation among individuals of S. rubecula. This high consistency

Symbols are not uniquely human [PDF]

open access: yes, 2006
Modern semiotics is a branch of logics that formally defines symbol-based communication. In recent years, the semiotic classification of signs has been invoked to support the notion that symbols are uniquely human.

Wild chimpanzees' use of single and combined vocal and gestural signals [PDF]

open access: yes, 2017
We describe the individual and combined use of vocalizations and gestures in wild chimpanzees. The rate of gesturing peaked in infancy and, with the exception of the alpha male, decreased again in older age groups, while vocal signals showed the opposite

Large‐Area 2D Metasurface‐Based Triboelectric E‐Skin Arrays: Contact & Proximity Tactile Mapping with Broadband Acoustic Readouts

open access: yesAdvanced Materials, EarlyView.
Metasurface‐engineered NC‐TENG arrays integrate tactile pressure mapping, non‐contact gesture sensing, and acoustic signal readouts in one ultrathin module, and outperforms pristine PDMS in terms of electrical output and real‐time spatial mapping for next‐gen wearables.

The Vocal Repertoire of Pale Spear-Nosed Bats in a Social Roosting Context

open access: yesFrontiers in Ecology and Evolution, 2019
Commonly known for their ability to echolocate, bats also use a wide variety of social vocalizations to communicate with one another. However, the full vocal repertoires of relatively few bat species have been studied thus far. The present study examined
