The mechanisms underlying vocal mimicry in animals remain an open question. Delphinidae are able to copy sounds from their environment that are not produced by conspecifics. Usually, these mimicries occur associated with the context in which they were learned. No reports address the question of separation between auditory memory formation and spontaneous vocal copying although the sensory and moto...

Behavioural asymmetries reflect brain asymmetry in nonhuman primates (NHP) as
in humans. By investigating manual laterality, researchers can study the evolution
of brain hemisphere specialisation. Three dominant theories aim to establish an
evolutionary scenario. The most recent theory relates different levels of manual
laterality to task complexity. Our investigation aimed to evaluate the importa...

Youngsters do not pay attention to conversational rules: is this so for nonhuman primates?

The potentiality to find precursors of human language in nonhuman primates is questioned because of differences related to the genetic determinism of human and nonhuman primate acoustic structures. Limiting the debate to production and acoustic plasticity might have led to underestimating parallels between human and nonhuman primates. Adult-young differences concerning vocal usage have been report...

Acoustic variability and social significance of calls in female Campbell’s monkeys (Cercopithecus campbelli campbelli)

Although the vocal repertoire of nonhuman primates is strongly constrained by genetic, a growing number of studies evidence socially determined flexibility. According to Snowdon et al. [Social Influences on Vocal Development (University Press, Cambridge, 1997), pp. 234–248], calls with a higher social function (affiliative or agonistic) would be expected to show more flexibility than lesser social...

Le langage humain est de loin le système de communication le plus élaboré,
mais parler, comme n’importe quel autre comportement, ne laisse aucune trace
directe de son évolution. Bien que des explications plausibles soient fournies par
les données archéologiques, celles-ci restent quantitativement limitées. Aussi,
rechercher l’origine phylogénétique du langage demeure une entreprise complexe

Background: Non-human primate communication is thought to be fundamentally different from human speech, mainly due to vast differences in vocal control. The lack of these abilities in non-human primates is especially striking if compared to some marine mammals and bird species, which has generated somewhat of an evolutionary conundrum. What are the biological roots and underlying evolutionary pres...

Communication and learning from each other are part of the success of animal societies. Social insects invest considerable effort into signalling to their nestmates the locations of the most profitable resources in their environment. Growing evidence also indicates that insects glean such information through cues inadvertently provided by their conspecifics. Here, we investigate social information...

Conclusion
A negative interaction can easily act as an evolutionary dead-end as it affects
the survival of one individual. By contrast, in a self-reinforcing cycle, a positive exchange can be beneficial to all the individuals involved, which emphasises the structuring force of interactions, a well-known process in ecology. In a community of proto-cell bubbles, species differences do not exist beca...

Habitat selection remains a poorly understood ecological process, but relating mating behaviour to pattern of habitat selection constitutes a fundamental issue both in evolutionary ecology and in biological conservation. From radiotelemetry protocol, habitat-induced variations in mating success were investigated in a solitary mustelid carnivore, the European polecat Mustela putorius. Selection for...

We studied the phylogeography of the strict savannah pygmy mice Mus (Nannomys) minutoides in West Central Africa. A total of 846 base pairs of the cytochrome b sequence were obtained for 66 individuals collected in Gabon, Cameroon, Republic of Congo and Central African Republic. These sequences were compared to those of M. minutoides from other African countries and to eight other species of the g...
