The phylogenetic relationships among 11 species of the Cervidae family were inferred from an analysis of male vocalizations. Eighteen characters, including call types (e.g. antipredator barks, mating loudcalls) and acoustic characteristics (call composition, fundamental frequency and formant frequencies), were used for phylogeny inference. The resu...

The phylogenetic relationships of Cervidae within the family and within the infra-order Pecora are still uncertain. Traditionally based on morphological data, phylogenetic trees have increasingly relied on molecular data for the last 15 years, without reaching a satisfying consensus solution. This study intends to explore behaviour, between the rut...

La présence du Lynx boréal, Lynx lynx, dans le sud-ouest de la France a toujours fait l'objet de controverses. La première interrogation concerne la date de sa disparition, puisque des indices de présence récents posent la question de sa survivance. La seconde question concerne l'espèce qui aurait disparu (ou qui serait encore présente) dans les Py...

More than one year after its appearance, SARS-CoV-2 virus has spread on our planet. Responsible for the symptoms associated with the disease called Covid-19, this virus has completely changed our lives and our societies. After several lockdowns and de-confinements of the population, and despite efforts to save lives by limiting its spread, our know...

- English and Chinese (simplified) versions available - The Olympic Charter states that “The goal of Olympism is to place sport at the service of the harmonious development of humankind, with a view to promoting a peaceful society concerned with the preservation of human dignity.” As athletes from across the globe gather together today for the st...

Plus d'un an après son apparition, le virus SARS-CoV-2 s'est répandu sur notre planète. Responsable des symptômes associés à la maladie appelée Covid-19, ce virus a bouleversé nos vies et nos sociétés. Après plusieurs confinements et déconfinements de la population, et malgré les efforts déployés pour sauver des vies en limitant la propagation du v...

We call on the World Health Organization and its Executive Board to fully address the recommendations and questions raised in this letter as a critical step toward protecting everyone on earth and future generations. As terrible as COVID-19 has been, this is almost certainly not the last pandemic we will face -- and possibly not even the worst. Ta...

Si les animaux et leurs comportements ont toujours fasciné les hommes, comme en attestent les peintures rupestres et les hiéroglyphes, ce n’est qu’à partir du 19e siècle qu’Isidore Geoffroy Saint-Hilaire (1854) désigne pour la première fois l’éthologie sous son appellation actuelle (ethos, mœurs). Mais derrière cet acte de naissance se cache une sc...

Muséologie du comportement Si l’action de conserver des objets constitue la pre�mière des missions d’un muséum, cette notion prend un sens d’autant plus universel que dans la plupart de nos institutions certains spécimens revêtent une importance à la fois scientifique et patrimoniale. Les types (holotype, syntype, etc.) qui ont servi à décrir...

Reaction to the China-WHO joint study team report. In our previous open letter, we outlined our fears that the joint international committee/Chinese government team “did not have the mandate, the independence, or the necessary accesses to carry out a full and unrestricted investigation into all the relevant SARS-CoV-2 origin hypotheses.” Having re...

As strong supporters of the WHO and its mission, we believe it must be made clear that any findings of the joint committee, while potentially useful to a limited extent, represent neither the official position of the WHO nor the result of an unrestricted, independent investigation. For this reason, we believe it is essential that the contours of a...

Les communications sonores se sont développées chez les Arthropodes et les Vertébrés. Pour communiquer ces animaux ont adapté leurs communications au milieu dans lequel ils vivent. Si certains animaux apprennent leurs vocalisations, ce qui aboutit à des dialectes, chaque son renferme aussi un signal évolutif qui permet d'établir des relations de pa...

Ethology was founded successively by the naturalist, psychological and neurophysiological trends. After the classic opposition between the environmentalist and the objectivist view on behavior, and then the constructivist currents of the naturalist ethology, a fi rst synthesis was proposed by Tinbergen’s four questions, integrating several scientif...

In this article, we examine the possible contribution of behavioural studies to the determination of phylogenetic relationships within the Bovidae. First, we revisit the general arguments concerning the use of behavioural traits as phylogenetic characters; then we present our first attempt at reconstructing the phylogeny of Bovidae based on behavio...

The Gargas Cave is a key site for the Gravettian in Europe because of its exceptional rock art and its rich archaeological filling. This site was excavated between the end of the nineteenth century and the beginning of the twentieth century. A new research program started in 2004, the main aim of which is to establish a precise chronological and cu...

Behavioural characters are still insufficiently used for inferring phylogenetic relationships in systematics. This study is aimed at analysing the possible interest of behavioural studies for resolving relationships in Cervids, a topic hotly debated for decades. Recent molecular studies seemed to be reaching a consensus, but these results are in co...
