Depuis plusieurs décennies la pression sur les aires protégées s’accroit à travers des infiltrations humaines pour la chasse, l’agriculture et l’orpaillage. De nos jours, les couloirs écologiques constituent une alternative durable face à la fragmentation et à l’isolement des aires protégées. Afin d’anticiper sur les éventuelles conséquences d’un i...

Les primates non-humains (PNH) sont observés dans les milieux périurbains sans protection, où leur survie est menacée, notamment à cause de l’urbanisation galopante qui réduit l’habitat et la disponibilité alimentaire. C’est le cas d’une population de 13 individus de Mones de Lowe, une espèce vulnérable selon la liste rouge de l’UICN, localisée dan...

Animal communication has long been thought to be subject to pressures and constraints associated with social relationships. However, our understanding of how the nature and quality of social relationships relates to the use and evolution of communication is limited by a lack of directly comparable methods across multiple levels of analysis. Here, w...

en Diet determination of endangered species is an essential element in defining successful conservation strategies and optimising captive breeding programmes. In this study, we developed a new diet identification system, derived from standard faecal analysis, to determine the diet of an elusive and endangered herbivore, the pygmy hippopotamus (Choe...

This study aimed to highlight the options selected by Campbell's monkey (Cercopithecus campbelli) to optimize foraging in the Taï National Park, Côte d'Ivoire. A group of C. campbelli, habituated to human's presence, was followed for two months in the dry season to test whether the three parameters (the distance traveled to reach the foraging sites...
Presentation
Full-text available
The white naped mangabey (Cercocebus lunulatus) is on the IUCN Red List of Critically Endangered Species and is endemic to 3 countries in West Africa. To date, while there are conservation efforts in Ghana, there is no established conservation strategy for this species, particularly in Côte d'Ivoire and Burkina Faso. At the risk of seeing this spec...
Article
Full-text available
Call combinations allow animals to expand the communicative power of small repertoires with acoustically inflexible elements. In Campbell's monkeys, Cercopithecus campbelli, males possess a small repertoire of calls that can be merged to an acoustically invariable suffix and which are concatenated into various sequences, mainly in response to exter...

The pygmy hippopotamus is an endangered species which receives little attention from the scientific community, especially wild populations. The highest density of wild pygmy hippopotamus is found in the Taï National Park in Ivory Coast which is inscribed on United Nations Educational, Scientific and Cultural Organization’s World Heritage list. T...
Article
Full-text available
We argue that rich data gathered in experimental primatology in the last 40 years can benefit from analytical methods used in contemporary linguistics. Focusing on the syntactic and especially semantic side, we suggest that these methods could help clarify five questions: (i) what morphology and syntax, if any, do monkey calls have? (ii) what is th...
Article
Full-text available
We explain why general techniques from formal linguistics can and should be applied to the analysis of monkey communication – in the areas of syntax and especially semantics. An informed look at our recent proposals shows that such techniques needn’t rely excessively on categories of human language: syntax and semantics provide versatile formal too...
Article
Compared to humans, non-human primates have very little control over their vocal production. Nonetheless, some primates produce various call combinations, which may partially offset their lack of acoustic flexibility. A relevant example is male Campbell's monkeys (Cercopithecus campbelli), which give one call type ('Krak') to leopards, while the su...
Article
A general pattern in animal behavior is that group-living species tend to bias their sociopositive behavior toward genetic relatives. In nonhuman primates, kin-biased social bonds have been reported in large multimale, multifemale macaque and baboon groups, but little is known for other species. We addressed this with a comparative study on the gen...
Chapter
The One Health concept of combined veterinary and human health continues to gain momentum, but the supporting literature is sparse. In this book, the origins of the concept are examined, and practical content on methodological tools, data gathering, monitoring techniques, study designs, and mathematical models is included. Zoonotic diseases, with d...

Full-text available
We develop a formal semantic analysis of the alarm calls used by Campbell’s monkeys in the Tai forest (Ivory Coast) and on Tiwai island (Sierra Leone)—two sites that differ in the main predators that the monkeys are exposed to (eagles on Tiwai vs. eagles and leopards in Tai). Building on data discussed in Ouattara et al. (PLoS ONE 4(11):e7808, 2009...
Article
We conducted surveys in Cote d'Ivoire's Bandama-Sassandra interfluvial region to assess the abundance of primates and investigate further a population of black-and-white colobus monkey whose taxonomic position has been debated. Primates were encountered in five of eight forests surveyed. The most common primates were Campbell's guenons and lesser s...
Conference Paper
Health research is at the crossroad of multiples disciplines and sectors and need collaboration and communication beyond single discipline border ranging from genes to the ecology. Health research implementation needs tools and methods that involve biology, biostatistics, modelling, risk analysis, transdisciplinarity. Health research also requires...
Book
The book presents new and stimulating approaches to the study of language evolution and considers their implications for future research. Leading scholars from linguistics, primatology, anthroplogy, and cognitive science consider how language evolution can be understood by means of inference from the study of linked or analogous phenomena in langua...

The Tanoé Forest is located within the original distribution area of the Miss Waldron red colobus (Piliocolobus badius waldronae), the diana roloway (Cercopithecus diana roloway) and the white napped mangabey (Cercocebus atys lunulatus). These three monkey species are classified by IUCN among the 25 most threatened monkeys of the world. Surveys con...
Article
Full-text available
In many primate species, individuals produce a finite number of acoustically distinct calls as part of a species-specific vocal repertoire. The calls usually have context-specific functions, such as defending a home range, avoiding predators, or alerting conspecifics to a food source, etc. In some primates, call systems are structurally more comple...

Full-text available
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...
Article
Call rate can be a salient feature in animal communication. Depending on the species, different psychological variables appear to influence call rates but the exact nature of these relationships remains poorly explored. Here, we demonstrate for free-ranging Campbell's monkeys that the call rates of four different alarm series (termed H, K, K(+), an...
Article
Population genetic analyses are of considerable importance for conservation strategies to protect endangered primates. We tested microsatellites of human origin with an aim to understand the genetic diversity of a West African forest guenon, Campbell's monkey, Cercopithecus campbelli. Twelve markers amplified successfully, were polymorphic and were...
Article
Habitat type, predation pressure and reproductive interests are all thought to determine the anti-predator behaviour of non-primates, but only few systematic studies exist. Here, we experimentally elicited anti-predator behaviour in six different groups of forest-living Campbell's monkeys, using visual and acoustic models of leopards, crowned eagle...
Article
Primate vocal behavior is often considered irrelevant in modeling human language evolution, mainly because of the caller's limited vocal control and apparent lack of intentional signaling. Here, we present the results of a long-term study on Campbell's monkeys, which has revealed an unrivaled degree of vocal complexity. Adult males produced six dif...
Data
“Krak” calls are exclusively given after detecting a leopard. (0.09 MB WAV)
Data
“Hok” calls are almost exclusively associated with crowned eagle presence. (0.05 MB WAV)
Data
“Hok-oo” are given to a range of disturbances within the canopy, including eagles, the presence of neighbouring groups and, on a few occasions, to a flying squirrel. While producing these calls, males adopt a threat posture, combined with flashing their eyelids, sometimes combined with a short dash towards the disturbance. (0.06 MB WAV)
Data
“Krak-oo” function as a general alert call and can be given to almost any disturbance. (0.09 MB WAV)
Data
“Wak-oo” calls are given to the same events as “hok-oo” calls (eagles, other flying animals, Diana monkey eagle alarms), but not to neighbours. (0.14 MB WAV)
Data
“Boom” calls are given to non-predatory contexts, such as a falling branch or tree, to initiate or halt group travel, during disputes with neighbours, and to any unusual vocal excitation with the group. (0.20 MB WAV)

Full-text available
Human language has evolved on a biological substrate with phylogenetic roots deep in the primate lineage. Here, we describe a functional analogy to a common morphological process in human speech, affixation, in the alarm calls of free-ranging adult Campbell's monkeys (Cercopithecus campbelli campbelli). We found that male alarm calls are composed o...
Article
Field studies on male forest guenon alarm-calling behaviour have revealed a number of intricacies about how these primates use vocalizations to protect themselves from predation. In these species, the vocal behaviour of adult females is often different from that of the males, but little systematic work has been done. Here, we describe the alarm cal...

Full-text available
Le débat sur l'existence de précurseurs du langage dans la communication vocale animale est toujours ouvert. Depuis 10 ans, les recherches sur les cercopithèques se multiplient car leur système social et leur habitat visuellement clos en font de bons modèles pour une telle comparaison. Nous avons conduit la première série d'observations éthologique...
Article
Full-text available
Human-induced extinction rate of fauna has increased over the last century. The danger is particularly acute in the tropics where conservation resources are scarcest, where habitat conversion is more rapid, and where the threat to biodiversity especially to primate species and populations is greatest. This is the case for the whole primate communit...
