- A call for CARE in animal behaviour: an holistic ethical research frameworkPublication . Badihi, Gal; Taylor-O’Connor, Jennifer; Daly, Gabriela Bezerra de Melo; Komeda, Viola; Daoudi-Simison, Sophia; Rodrigues, Evelina D.; Webster, Michael M.; Altschul, Drew M.; Hobaiter, Catherine; Wiltshire,Charlotte; Klein, Harmonie; Freymann, Elodie; Grund, Charlotte; Soldati, Adrian; Henderson, Matthew; Leroux, Maël M.; Slania, Nora E.; ElseviorDespite increasing awareness of animal welfare, there are vast discrepancies between legal protections and recommended practices for different species, in different countries and at different institutions. While many guidelines are now available, they often target specific research contexts or species, leaving a gap in compre hensive ethical oversight across the entire research process. Within animal behaviour research, there is a bias for considering ethics during only the methodology and design phase. This often means only the immediate impact on animals directly involved in the research is accounted for. Conducting ethical research should extend beyond ensuring animal welfare during data collection and include environmentally sustainable research practices, alongside the ethical treatment of people working within and alongside animal behaviour research. We offer the Consult, Approve, Research and Evaluate (CARE) framework to improve the scientific integrity, transparency and ethical practices within the field of animal behaviour. CARE encourages researchers and academic bodies to (1) Consult existing (academic and traditional) knowledge on the study species, local human—animal interactions, their environment and previously implemented ethical practices and to reflect on personal experience and biases when approaching a study question; (2) seek Approval from relevant bodies (e.g. institutional ethics committees and local and government authorities) even when not mandatory; (3) uphold ethical standards while carrying out Research and (4) Evaluate the short- and long-term impacts of the specific study. Our framework is designed to distribute accountability at every level of the academic system, from individual re searchers to their institutions, funding bodies and publishers. We pitch this framework as a ‘version 1.0’ to recognize the fast-evolving nature of ethical standards in animal behaviour research and to allow space for improvement. CARE provides a necessary infrastructure for addressing systemic biases and ensuring ethically sound, socially responsible and environmentally sustainable animal behaviour research.
- Connecting primate gesture to the evolutionary roots of language: A systematic reviewPublication . Rodrigues, Evelina Daniela; Santos, António J.; Veppo, Flávia; Pereira, Joana; Hobaiter, CatherineComparative psychology provides important contributions to our understanding of the origins of human language. The presence of common features in human and nonhuman primate communication can be used to suggest the evolutionary trajectories of potential precursors to language. However, to do so effectively, our findings must be comparable across diverse species. This systematic review describes the current landscape of data available from studies of gestural communication in human and nonhuman primates that make an explicit connection to language evolution. We found a similar number of studies on human and nonhuman primates, but that very few studies included data from more than one species. As a result, evolutionary inferences remain restricted to comparison across studies. We identify areas of focus, bias, and apparent gaps within the field. Different domains have been studied in human and nonhuman primates, with relatively few nonhuman primate studies of ontogeny and relatively few human studies of gesture form. Diversity in focus, methods, and socio‐ecological context fill important gaps and provide nuanced understanding, but only where the source of any difference between studies is transparent. Many studies provide some definition for their use of gesture; but definitions of gesture, and in particular, criteria for intentional use, are absent in the majority of human studies. We find systematic differences between human and nonhuman primate studies in the research scope, incorporation of other modalities, research setting, and study design. We highlight eight particular areas in a call to action through which we can strengthen our ability to investigate gestural communication's contribution within the evolutionary roots of human language.

- Exploring greetings and leave-takings: communication during arrivals and departures by chimpanzees of the Bossou community, GuineaPublication . Rodrigues, Evelina Daniela; Santos, António J.; Hayashi, Misato; Matsuzawa, Tetsuro; Hobaiter, CatherineIn human fission–fusion societies, ritualized non-linguistic signal exchanges that include gestures, vocalizations, and facial expressions are regularly observed at both arrivals (greetings) and departures (leave-takings). These communicative events play an important role in the formation and maintenance of social relationships. Wild chimpanzees also form large communities that split into smaller fluid parties during daily activities, with individuals moving freely between them. However, in chimpanzees only greetings have been reported. This study explores signal exchanges in the Bossou chimpanzee community during fissions (departures) and fusions (arrivals) given an individual’s social rank, kinship, position as traveller or party-member, the level of potential threat, and the party size and presence of mature males. We analysed three time periods (1993–1994; 2003–2004; 2013–2014) during which the composition and social hierarchy of the community varied. We show that the occurrence and form of communication during fission and fusion events are mediated by social factors, including rank, kinship, and party size and composition. Individuals were more likely to communicate during fusions than during fissions, communication was more likely to be produced towards a higher-ranking individual and to non-kin individuals, but the tendency to communicate in general increased with an increase in social rank. The presence of more individuals, and in particular mature males, decreased the likelihood of communication. Communication during fusions supported patterns reported in previous studies on greetings, and our results support the argument that, if present, leave-takings are not a common feature of chimpanzee social interactions. Current methodological difficulties regarding the function of declarative signals hinder our ability to discriminate potential parting rituals within communication before departures. Given similar methodological difficulties, we also provide a note of caution in the interpretation of all signals produced during fusions as ‘greetings’.
