Inferring the evolutionary history of cognitive abilities requires large and diverse samples. However, such samples are often beyond reach individual researchers or institutions, studies limited to small numbers species. Consequently, methodological site-specific-differences across can limit comparisons between Here we introduce ManyPrimates project, which addresses these challenges by providing a large-scale collaborative framework for comparative in primate cognition. To demonstrate...
Contemporary evolutionary theories propose that living in groups drives the selection of enhanced cognitive skills to face competition and facilitate cooperation between individuals. Being able coordinate both space time with others make strategic decisions are essential for cooperating within groups. Social tolerance an egalitarian social structure have been proposed as one specific driver cooperation. Therefore, is predicted be associated underpin communication coordination. should also...
Mouse lemurs are suggested to represent promising novel non-human primate models for aging research. However, standardized and cross-taxa cognitive testing methods still lacking. Touchscreen-based procedures have proven high stimulus control reliability in humans rodents. The aim of this study was adapt these mouse lemurs, thereby exploring the effect age. We measured appetitive learning flexibility two age groups by applying pairwise visual discrimination (PD) reversal (PDR) tasks. On...

Human and non-human primates exhibit facial movements or displays to communicate with one another. The evolution of form function those could be better understood through multispecies comparisons. Anatomically based coding systems (Facial Action Coding Systems: FACS) are developed enable such comparisons because they standardized systematic aid identification homologous expressions underpinned by similar muscle contractions. To date, FACS has been for humans, subsequently modified...
Large-brained diurnal mammals with complex social systems are known to plan where and how reach a resource, as shown by systematic movement pattern analysis. We examined for the first time large-scale patterns of solitary-ranging small-brained mammal, mouse lemur ( Microcebus murinus ), using change-point test heuristic random travel model get insight into foraging strategies potential route-planning abilities. Mouse lemurs small nocturnal primates inhabiting seasonal dry deciduous forest in...
The origin of human handedness and its evolution in primates is presently under debate. Current hypotheses suggest that body posture (postural hypothesis bipedalism hypothesis) have an important impact on the primates. To gain insight into manual lateralization primates, we studied gray mouse lemurs, suggested to represent most ancestral primate condition. First, investigated hand preference a simple food grasping task explore importance usage natural foraging situation. Second, explored...
Inhibitory control, the inhibition of impulsive behaviours, is believed to be key in navigating a complex social environment. Species characterised by higher tolerance, living more groups, with diverse relationships, face uncertainty regarding outcome interactions and, therefore, would benefit from employing inhibitory strategies. To date, little known about selective forces that favour evolution control. In this study, we compared control skills three closely related macaque species which...
Inhibitory control, the ability to override an inappropriate prepotent response, is crucial in many aspects of everyday life. However, various paradigms designed measure inhibitory control often suffer from a lack systematic validation and have yielded mixed results. Thus nature this remains unclear, it general construct or family distinct sub-components? Therefore, aim study was first demonstrate content validity temporal repeatability battery tasks. Then we wanted assess contextual...
Abstract Climate change is associated with more frequent extreme weather conditions and an overall increase in temperature around the globe. Its impact on individual ecosystems not yet well known. Long-term data documenting climate temporal abundance of food for primates are scarce. We used long-term phenological to assess variation, fruit home range sizes endemic Critically Endangered crested macaques ( Macaca nigra ) Tangkoko forest, Sulawesi, Indonesia. Between January 2012 July 2020,...
Abstract Field observations suggest that the diet of Malagasy gray mouse lemur consists not only non‐stationary animal prey (invertebrates or small vertebrates), but also stationary food resources such as gum homopteran larvae secretions (HLS). We studied foraging behavior five lemurs radiotelemetrically, each during six consecutive nights in dry season, to explore which extent they use these and whether there is evidence for their relocation. found animals used all three different...
Abstract Affiliation/agonism and social dominance are central factors determining organization in primates. The aim of our study is to investigate describe, for the first time, intersexual relations a nocturnal cohesive pair‐living prosimian primate, western woolly lemur ( Avahi occidentalis ), determine what extent phylogeny, activity mode, or cohesiveness pair partners shape quality interactions. Six pairs lemurs were radio‐collared dry deciduous forest northwestern Madagascar. More than...

The aim of this study to explore the role acoustic signaling for spacing cohesiveness nocturnal, cohesive, pair‐living strepsirrhine. Material Methods was conducted northwestern Madagascar. Six pairs Avahi occidentalis were radio‐collared home range usage, vocalizations call‐associated behavior recorded using GPS‐based focal animal sampling. Home size analyzed ArcView GIS...
Short-term memory is implicated in a range of cognitive abilities and critical for understanding primate evolution. To investigate the effects phylogeny, ecology sociality on short-term memory, we tested largest most diverse sample to date (421 non-human primates across 41 species) an experimental delayed-response task. Our results confirm previous findings that longer delays decrease performance species taxa. analyses demonstrate considerable contribution phylogeny over ecological social...
Background Recent results in birds, marsupials, rodents and nonhuman primates suggest that phylogeny ecological factors such as body size, diet postural habit of a species influence limb usage the direction strength laterality. To examine to which extent these findings can be generalised small-bodied rooting quadrupedal mammals, we studied trees shrews (Tupaia belangeri). Methodology/Principal Findings We established behavioural test battery for examining paw comparable tested 36 Tupaia...
A recent study suggests that a specific, touchscreen-based task on visual object-location paired-associates learning (PAL), the so-called Different PAL (dPAL) task, allows effective translation from animal models to humans. Here, we adapted nonhuman primate (NHP), gray mouse lemur, and provide first evidence for successful comparative application of humans NHPs. Young human adults reach criterion after considerably less sessions (one order magnitude) than young, adult NHPs, which is likely...
Nonhuman primates may defend crucial resources using acoustic or chemical signals. When essential are limited, ownership display for a resource be enhanced. Defending depend on population density and habitat characteristics. Using the Milne Edwards' sportive lemurs (Lepilemur edwardsi) weasel (L. mustelinus) as models, we tested whether two cryptic nocturnal lemur species differing in show differences their vocal communication signaling of resources. L. edwardsi inhabits western dry...
Inhibitory control, the ability to override a dominant response, is crucial in many aspects of everyday life. In animal studies, striking individual variations are often largely ignored and their causes rarely considered. Hence, our aims were systematically investigate variability inhibitory replicate most common variation (age, sex rank) determine if these factors had consistent effect on three main components control (inhibition distraction, inhibition an action, cognitive set). We tested...
