Abstract Large brains and behavioural innovation are positively correlated, species-specific traits, associated with the flexibility animals need for adapting to seasonal unpredictable habitats. Similar ecological challenges would have been important drivers throughout human evolution. However, studies examining influence of environmental variability on within-species diversity lacking despite critical assumption that population diversification precedes genetic divergence speciation. Here,...
More than just numbers We often frame negative human impacts on animal species in terms of individuals reduced or regions from which are absent. However, activities likely affecting more complex ways these figures can capture. Kühl et al. studied behavioral and cultural diversity our closest relative, the chimpanzee. They found that human-mediated disturbance is reducing traits. Human influence thus goes well beyond simple loss populations species, leading to change even where persist....
How populations adapt to their environment is a fundamental question in biology. Yet, we know surprisingly little about this process, especially for endangered species, such as nonhuman great apes. Chimpanzees, our closest living relatives, are particularly notable because they inhabit diverse habitats, from rainforest woodland-savannah. Whether genetic adaptation facilitates habitat diversity remains unknown, despite it having wide implications evolutionary biology and conservation. By...
Abstract The study of the archaeological remains fossil hominins must rely on reconstructions to elucidate behaviour that may have resulted in particular stone tools and their accumulation. Comparatively, tool use among living primates has illuminated behaviours are also amenable examination, permitting direct observations leading artefacts assemblages be incorporated. Here, we describe newly discovered tool-use accumulation sites wild chimpanzees reminiscent human cairns. In addition data...
Abstract Monitoring populations in areas of ecological transition is crucial to understanding species distributions, but also a critical conservation tool. We used camera trapping investigate the forest mammal community Batéké Plateau National Park ( BPNP ) Gabon, transitional landscape that experiences severe poaching. compiled inventory, investigated group sizes and activity patterns observed species, conducted an initial test evaluate whether gradients within this influence occurrence....
Knowledge on the population history of endangered species is critical for conservation, but whole-genome data chimpanzees (Pan troglodytes) geographically sparse. Here, we produced first non-invasive geolocalized catalog genomic diversity by capturing chromosome 21 from 828 samples collected at 48 sampling sites across Africa. The four recognized subspecies show clear genetic differentiation correlating with known barriers, while previously undescribed exchange suggests that these have been...
Abstract Much like humans, chimpanzees occupy diverse habitats and exhibit extensive behavioural variability. However, are recognized as a discontinuous species, with four subspecies separated by historical geographic barriers. Nevertheless, their range-wide degree of genetic connectivity remains poorly resolved, mainly due to sampling limitations. By analyzing geographically comprehensive sample set amplified at microsatellite markers that inform recent population history, we found...
Strontium isotope (87Sr/86Sr) analysis with reference to strontium landscapes (Sr isoscapes) allows reconstructing mobility and migration in archaeology, ecology, forensics. However, despite the vast potential of research involving 87Sr/86Sr particularly Africa, Sr isoscapes remain unavailable for largest parts continent. Here, we measure ratios 778 environmental samples from 24 African countries combine this data published model a bioavailable isoscape sub-Saharan Africa using random forest...
Abstract Paleoclimate reconstructions have enhanced our understanding of how past climates shaped present‐day biodiversity. We hypothesize that the geographic extent Pleistocene forest refugia and suitable habitat fluctuated significantly in time during late Quaternary for chimpanzees ( Pan troglodytes ). Using bioclimatic variables representing monthly temperature precipitation estimates, human population density data, an extensive database georeferenced presence points, we built a model...

Lions (Panthera leo) are of particular conservation concern due to evidence recent, widespread population declines in what has hitherto been seen as a common species, robust anthropogenic disturbance.

Abstract The question of how behavioural diversity in humans and other animals is shaped by the combined influence demography, genetics, culture, environment receives much research attention. We take a macro-ecological approach to evaluate chimpanzee ( Pan troglodytes ) spatially structured associated with genetic (i.e. heterozygosity as proxy for effective population size) contemporary historic environmental context. integrate largest available genomic datasets apply explicit Bayesian...
