The plastic nature of cat behaviour allows this “friendly symbiont” of humans to adapt to various housing conditions. Beyond daylight, one could wonder if other environmental factors affect its patterns. Yet, how its activity and feeding rhythms are impacted by its environment is rarely studied in standardised conditions between populations. We com...

Full-text available
Different synchronizers can modify daily rhythms during an annual cycle. Nevertheless, the fluctuation of these external factors is often ignored in studies on cat locomotor activity and feeding rhythms, thereby focusing on one single season. To fill this gap, the activity and feeding rhythms of six cats living in a research cattery, receiving natu...

Visual communication involves specific signals. These include the different positions of mobile body elements. We analyzed visual configurations in cats that involve ears and the tail. We aimed at deciphering which features of these configurations were the most important in cats’ interactions with other cats and with humans. We observed a total of...

English Summary. The Human-Animals Relations Committee of the French Veterinary Academy examined the private member's bill No. 3661 registered at the Presidency of the French National Assembly on December 14, 2020 to strengthen the fight against animal abuse. His critical study was based on the conviction that "Science" and "Law" share two absolut...
Article
Cet article, propose une synthèse des différents concepts-clés éthologiques qui constituent le cadre de l’analyse du bien-être animal. Le premier constat est que les animaux sur lesquels nous travaillons ne sont pas des machines réagissant à des schémas préétablis. Ils ont une liberté d’action et prennent des décisions qui font appel à des capacité...
Article
La primatologie n'est pas une discipline de la biologie à proprement parler mais est le dénominateur commun de multiples disciplines de la biologie, écologie, éthologie, psychologie comparée, physiologie, recherches biomédicales, paléontologie, anthropologie, etc. : toutes ces disciplines ont les primates comme sujets. Cet article montre, à travers...
Article
Full-text available
Background Daily rhythms have been widely investigated in various mammals but, surprisingly, literature is scarce and conflicting regarding the domestic cat, Felis catus. This may come from the difficulty to analyse rhythms in a species showing high interindividual variability and from the common idea that the rhythms of the cat are rather random....
Article
The study of mammalian societies and other similar social groups requires identification of group members and documentation of their spatial organization. Ultra-wide band technology is a pioneering research technique which allows real time automatic recording of the location of each group member. Cats living in a group were equipped with active tra...

Book
Full-text available
Social interactions can be viewed as “dialogs” during which messages between partners can be multimodal, consisting of several simultaneous or sequential signals from different sensory modalities. The nature of a message and the way it will be interpreted may depend on the signals, their order, but also the time intervals between them. This study a...

In most social interactions, an animal has to determine whether the other animal belongs to its own species. This perception may be visual and may involve several cognitive processes such as discrimination and categorization. Perceptual categorization is likely to be involved in species characterized by a great phenotypic diversity. As a consequenc...

To identify the causes of anaemia, other than acute blood loss, in dogs and to determine whether severity of anaemia provides clues to the diagnosis. The veterinary medical database of the Veterinary Campus Hospital, Lyon was searched. Dogs with anaemia (packed cell volume <37%) were included and assigned to different disease groups. Dogs with acut...
Article
Ethology has its roots in the observations of naturalists from Aristotle to the 19th century. It is also anchored in the studies of 19th century comparative psychologists, especially those defending the experimental method. Ethology refutes an approach solely based on a stimulus-response (S-R) link obtained in a laboratory by an experimenter. The f...
Article
Ethology, the «biology of behaviour», is a fundamental scientific field. It analyses the interaction between an animal, including man, and its environment. Ethology is closely related to other scientific disciplines, such as physiology, endocrinology, neurobiology, and cognitive sciences. The teaching of ethology is based on peer-reviewed papers pu...

included humans. A reversal learning phase followed the generalization phase, where the rewarded image was then that of the non-dog image. In order to reach the criterion of success, subjects had to choose the S+ at least 10 times during each of 2 successive 12-trial sessions. The 9 subjects were all able to group all the images of dogs within a sa...
Article
Capuchin monkeys have provided uneven evidence of matching actions they observe others perform. In accord with theories emphasizing the attentional salience of object movement and spatial relationships, we predicted that human-reared monkeys would better match events in which a human demonstrator moved an object into a new relation with another obj...
Article
Full-text available
In apes, four criteria are set to explore referential and intentional communication: (1) successive visual orienting between a partner and distant targets, (2) the presence of apparent attention-getting behaviours, (3) the requirement of an audience to exhibit the behaviours, and (4) the influence of the direction of attention of an observer on the...

Faces have features characteristic of the identity, age and sex of an individual. In the context of social communication and social recognition in various animal species, facial information is relevant for discriminating between familiar and unfamiliar individuals. Here, we present two experiments aimed at testing the ability of cattle (Bos taurus)...
Article
For more than ten years, reproductive biotechnologies using somatic cell nuclear transfer have made possible the production of cloned animals in various domestic and laboratory species. The influence of the cloning process on offspring characteristics has been studied in various developmental aspects, however, it has not yet been documented in deta...
Article
Yawning is a common, species-typical behaviour in vertebrates, generally associated with transitions from sleep to wakefulness. In primates, yawning occurs within a group in a variety of social contexts, suggesting that it has a communicative role, a hypothesis examined in this study. Yawning has rarely been studied. Quantitative studies have been...
Article
The basic vocal repertoire of the Crested Gibbon (Hylobates concolor leucogenys) can be defined from qualitative and quantitative analysis of the vocalizations. From sonagraphic analysis of calls of 9 juveniles, one adult ♂, one sub-adult ♂ and one sub-adult ♀ arranged in three semi-free living groups, one can describe six vocal types on a morpholo...
Article
Integration of information coming from several sensory modalities is crucial for communication and individual recognition in many species. In this experiment, we tested 6 grey-cheeked mangabeys with still pictures and vocalizations of familiar conspecifics. During the tests, the subjects faced 2 computer screens. Pictures of different familiar cons...
Article
Full-text available
Background: In order to maintain cohesion of groups, social animals need to process social information efficiently. Visual individual recognition, which is distinguished from mere visual discrimination, has been studied in only few mammalian species. In addition, most previous studies used either a small number of subjects or a few various views a...
Article
It is well documented that hamadryas baboons were used by the ancient Egyptians to pick fruits, but it is not well known that these baboons were also used to collect palm nuts. We describe this practice as it is depicted on a painting on a rarely exhibited ancient Egyptian artefact. Striking similarities with the modern use of pig-tailed macaques a...
Article
Unlike rhythmic activities such as feeding and reproduction, aggressive behaviour is triggered mainly by external stimuli and relational factors. The function of aggressive behaviour is to increase or maintain a certain distance between individuals, whether they belong to the same species or not. However, in social species forming permanent cohesiv...
Article
While an increasing number of animals are produced by means of somatic cloning, behavioral studies on cloned animals are still rare. The aim of this study was to investigate whether the somatic cloning procedure has an influence on locomotion, exploratory, vocal and social behaviors of heifers. Ten heifers were used in the present study. Five of th...

Species discrimination has been described in several taxa but rarely in domestic animals. In contrast to wild species, domestic species present a great phenotypic variety. This study investigated whether 10 Prim'Holstein heifers (Bos taurus) could discriminate images of cows from images of other domestic animals. The experiment was based on simulta...
Article
In order to characterize age-related cognitive changes, olfactory discrimination was assessed in Microcebus murinus, a prosimian primate. We compared young (n = 10) and old (n = 8) animals for individual performance on three olfactory tasks. Animals had to perform a detection, a transfer, and a reversal learning task using a go, no go conditioning...
Article
Charles Darwin would have said that yawning was a useless piece of physiology. If so, then how should the survival of this very stereotyped behavior among the poikilothermal and homoeothermic vertebrates, from the basic brained reptiles to human primates, whether in the air, on the land or in the sea be understand? This issue of the ethnological, n...

The present study was aimed at adapting an automated olfactometer designed for use with rodents to a nocturnal lemur Microcebus murinus. This apparatus allows rigorous control of odor stimuli. We show that M. murinus could remain quiet and attentive for about 20 min in the test chamber, allowing daily sessions of 40 consecutive trials. This allowed...
Article
A preference for novelty paradigm was used to investigate whether mangabeys (Lophocebus albigena), an arboreal non-human primate species, were able to discriminate and to categorize different visual stimuli belonging to natural (food items) and abstract (non-food items) categories. In a comparative perspective human subjects were tested with the sa...
Article
Twisting definitions of a concept to serve one's purposes is rarely a fruitful exercise and the demonstration of culture is, necessarily, a two-step procedure: (1) documenting a behavioral difference between populations, (2) demonstrating that this difference has spread through the group by means of social learning. This will avoid putting the cart...
Article
Social ontogeny is described as one component of the general process of ontogeny that refers explicitly and only to the development of an individual. It deals more specifically with the development of behaviors and cognitive abilities necessary for an individual to live in an organized social milieu. Because these aspects of individual development...

Chez les grands singes, les deux domaines de la cognition suscitent des interrogations dans la perspective de l'évolution : pourquoi l'homme et les grands singes, qui partagent tant de trais communs dans leur biologie, paraissent-ils si différents dans leurs compétences comportementales, comme certains aiment à le faire croire ?
Article
Eight pregnant rhesus monkeys were injected with 100 microg diethylstilbestrol dipropionate (DESDP) from the 40th day of gestation until term, a long-term treatment. Male (n = 3) and female (n = 5) offspring were obtained. Five other pregnant females were injected with DESDP beginning on the 115th day of gestation and continuing until either the 14...
Article
As a consequence of a severe reduction in their autonomy, the social life of people with quadriplegia becomes highly routine. In addition, the social environment becomes very limited because people without disabilities may feel awkward around, or have an aversion to, people with quadriplegia. A pet animal often facilitates social interactions betwe...
Article
All animal-assisted therapy programs raise ethical issues. These ethical issues are even more important when non-domesticated animals are used to help humans with disabilities. In their 1991 review, Iannuzzi and Rowan mentioned programs which use capuchin monkeys to help quadriplegics. The lack of technical or scientific information concerning thes...
Article
In a previous study, we demonstrated the importance of social interactions in the development of non-human primate infants. These results confirmed the social network concept. According to this concept, it is assumed that socialization processes would differ in various social environments. However, much variability remained to be explained. In the...

We hypothesized that, within a primate group, socialization processes are influenced by each group member behaving according to his own social network. Therefore socialization processes would differ in various social environments. In this study, we considered two main socialization processes, the acquisition of a social behavioral repertoire and th...
Article
Environmental enrichment is expected to increase the well-being of animals. Changes in well-being can be measured by variations in behavioral patterns. This study reports on behavioral changes induced, in arboreal monkeys, by progressively increasing the number of perches, from none to five, in an “experimental cage.” A cage equipped with five perc...

This study was designed to determine how to suppress behavioral effects of androgens with a pure non-steroidal antiandrogen, Hydroxyflutamide (OHF). The major dependent variable was yawning behavior of castrated adult male rhesus macaques. Injections of testosterone propionate (TP) increased yawning frequency and cessation of TP injections produced...

This preliminary study reports manipulations in an 8-month infant capuchin monkey,Cebus apella, confronted with a variety of objects, during five 2-hour sessions. This subject is raised in a human environment as it participates to the “Aide Simienne aux Personnes Handicapées (Kerpape)” project. Objects have been chosen in order to expose the capuch...
Article
Ontogeny refers to every aspect of the development of an individual. In this respect growth and sexual maturation are useful life-history parameters that can be correlated with developmental features of social behavior. In this paper, I analyze body-weight growth and sexual maturation in captive gray-cheeked mangabeys (Cercocebus albigena). I also...
Article
This paper reports reproductive parameters for 9 female grey-cheeked mangabeys kept in a captive colony over a 17-year period. Birth seasonality has shown a consistent trend towards an autumn peak. Oestrous cycles had an average length of 31.2 days: however 'short-cycle' (29.9 days) and 'long-cycle' (37.7 days) groups could be discriminated. Gestat...
Article
Socialization processes lead to creation and differentiation of social relationships. It is often difficult to qualify them, especially due to ontogenic changes of social behavior. In this paper, an attempt is made to assess the role of each partner in a dyad by defining the quality of their overall relationship. A Social Investment Index (SII) was...
Article
In 234 copulations, male and female behavioural patterns were collected, especially the vocal pattern for the female. Moreover quantitative structural analysis was performed on 38 of these female copulatory vocalizations. A multifactorial analysis, ANAFAC, was performed to seek relations between (1) utterance of female copulatory call and male and...
Article
Dans notre groupe captif de Macaca fascicularis, le comportement "Marche queue dressée", quand il est effectué par le ♂ "alpha", ne conduit à des poursuites que lorsqu&apos;il est orienté vers une ♀. Ces poursuites se terminent généralement par des morsures du ♂ sur ia ♀. Elles sont plus fréquentes à l&apos;égard de la ♀dominante, quelque soit la p...
Article
The 'tail-up' display, when performed by the 'alpha' male leads to 'stalking' when oriented towards a female. These pursuits are more frequent towards the dominant female, in any phases of her reproductive cycle. When modifications of the social structure occur, there is a positive correlation between 'stalking' and the frequencies of all other ago...
