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 Primates are facing an impending extinction crisis, driven by extensive habitat loss, land use change and hunting. Climate is additional threat, which alone or in combination with other drivers, may severely impact those taxa unable to track suitable environmental conditions. Here, we investigate the extent of climate use/cover (LUC) change‐related risks for primates. We employed analytical approach objectively select a subset scenarios, then calculated changes climatic LUC...
DNA sequences have been widely used for taxonomy, inferring phylogenetic relationships and identifying species boundaries. Several specific methods to define delimitations based on molecular phylogenies appeared recently, with the generalized mixed Yule coalescent (GMYC) method being most popular. However, only few studies land plants published so far GMYC analyses of bryophytes are missing. Dicranum is a large genus mosses whose (morpho-)species partly ill-defined frequently confused. To...
Abstract Aim Comparative phylogeography across a large number of species allows investigating community‐level processes at regional and continental scales. An effective approach to such studies would involve automatic retrieval georeferenced sequence data from nucleotide databases (a first step towards an ‘automated phylogeography’). It remains unclear if, despite repeated calls, georeferencing has increased in frequency, if accumulated allow for broad applications based on automated...
Abstract Questions Which environmental variables influence grass diversity in West Africa? What are the effects of climate and functional traits on spatial patterns (richness abundance) clades Andropogoneae, Paniceae Chloridoideae? Location Africa, demarcated by Atlantic Ocean west south (20° W 4° N), Sahara desert north (25° N) border between Niger Chad east E). Methods Based 38 912 georeferenced occurrence records, we modelled distribution 302 species (51% African diversity). We integrated...
ABSTRACT Aim Modelling African great ape distribution has until now focused on current or past conditions, whilst future scenarios remain scarcely explored. Using an ensemble forecasting approach, we predicted changes in taxon-specific under of climate, land-use and human population changes. Location Sub-Saharan Africa Methods We compiled occurrence data populations from the IUCN A.P.E.S. database extracted relevant human-, climate- habitat-related predictors representing (2050) conditions...
Abstract Aim Modelling African great ape distribution has until now focused on current or past conditions, while future scenarios remain scarcely explored. Using an ensemble forecasting approach, we predicted changes in taxon‐specific under of climate, land use and human populations for (1) areas outside protected (PAs) only (assuming complete management effectiveness PAs), (2) the entire study region (3) interspecies range overlap. Location Tropical Africa. Methods We compiled occurrence...
We investigated occurrences and patterns of terrestrial nocturnal activity in wild chimpanzees (Pan troglodytes) modelled the influence various ecological predictors on activity.Data were extracted from camera-trap footage surveys 22 chimpanzee study sites participating Pan African Programme: The Cultured Chimpanzee. described videos demonstrating activity, we tested effects percentage forest, abundance predators (lions, leopards hyenas), large mammals (buffalos elephants), average daily...
Abstract As camera trapping grows in popularity and application, some analytical limitations persist including processing time accuracy of data annotation. Typically images are recorded by traps although videos becoming increasingly collected even though they require much more for To overcome with image annotation, trap studies linked to community science (CS) platforms. Here, we extend previous work on CS annotations from a challenging environment; dense tropical forest low visibility high...

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...
Gut microbial communities are drivers of primate physiology and health, but the factors that influence gut microbiome in wild populations remain largely undetermined. We report data from a continent-wide survey chimpanzee microbiota highlight effects genetics, vegetation, potentially even tool use at different spatial scales on microbiome, including bacteria, archaea, eukaryotic parasites.
Abstract The predation and consumption of animals are common behaviours in chimpanzees across tropical Africa. To date, however, relatively little is known concerning the hunting behaviour central ( Pan troglodytes ). Here, we provide first direct observations by individuals newly habituated Rekambo community Loango National Park, Gabon. Over a period 23 months (May 2017 to March 2019), observed total 61 attempts on eight mammal species, including four monkey species. two most frequently...

We hypothesize that habitat stability in historical Afrotropical refugia played a major role the suitability and persistence chimpanzees ( Pan troglodytes ) during late Quaternary. aimed to build dynamic model changing for at fine spatio-temporal scales provide new resource their ecology, behaviour evolution.

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...
