Vocal individuality cues in the African penguin (Spheniscus demersus): a source-filter theory approach
- PhysicsScientific reports
- 2015
It is suggested that studying the anatomical constraints that influence nesting penguin vocalisations from a source-filter perspective, can lead to a much better understanding of the acoustic cues of individuality contained in their calls.

Experimental predator intrusions in a cooperative breeder reveal threat-dependent task partitioning
- Psychology
- 2020
It is shown how breeders and helpers of the cooperatively breeding cichlid Neolamprologus savoryi partition predator defense depending on intruder type and the presence of dependent young, and that in a highly social fish different group members exhibit fine-tuned behavioral responses in dependence of ecological and reproductive parameter variation.
Vocal individuality of Holstein-Friesian cattle is maintained across putatively positive and negative farming contexts
- PsychologyScientific Reports
- 2019
This study shows that cattle vocal individuality of high-frequency calls is stable across different emotionally loaded farming contexts, with all vocal parameters except subharmonics responsible for this individual distinctiveness.
Discrimination of Acoustic Stimuli and Maintenance of Graded Alarm Call Structure in Captive Meerkats
- BiologyAnimals : an Open Access Journal from MDPI
- 2021
It is demonstrated that meerkats (Suricata suricatta) living in zoos can assess potential danger and respond naturally based on acoustic signals only and that the graded information of urgency in alarm calls as well as a response to those alarm calls is retained in captivity.
Vocal Production by Terrestrial Mammals: Source, Filter, and Function
- Biology
- 2016
This chapter draws together a wealth of research conducted over the last two decades, and describes how source- and filter-related acoustic components encode functionally relevant information in the vocal communication systems of terrestrial mammal and how selection pressures have led to the evolution of anatomical innovations that enable animals to produce exaggerated vocal traits.

2 key acoustic features that Australian sea lion (Neophoca cinerea) males most likely rely on to assess the threat level posed by potential rivals are investigated, by manipulating bark rhythmicity and spectral characteristics.
Flexible alarm calling in meerkats: the role of the social environment and predation urgency
- Psychology
- 2012
The results indicate that variation in alarm call production depends on whom the call is addressed to and also on the motivational state of the caller, suggesting that neglecting to integrate internal and external factors when elucidating mechanisms underlying vocal production can potentially lead to misguided, parsimonious conclusions regarding vocal flexibility in animals.
All clear? Meerkats attend to contextual information in close calls to coordinate vigilance
- PsychologyBehavioral Ecology and Sociobiology
- 2011
This is the first evidence for socially foraging animals using the information encoded within calls, the main adaptive function of which is unrelated to immediate predator encounters, to coordinate their vigilance behaviour, and new insights are provided into the potential cognitive mechanisms underlying anti-predator behaviour.

It is argued that social monitoring based on non-agonistic cues is probably a common mechanism in group-living species that allows the adjustment of behaviour depending on variation in relationships.
