The question of whether animals possess ‘cultures’ or ‘traditions’ continues to generate widespread theoretical and empirical interest. Studies wild chimpanzees have featured prominently in this discussion, as the dominant approach used identify culture was first applied them. This procedure, ‘method exclusion,’ begins by documenting behavioural differences between groups then infers existence eliminating ecological explanations for their occurrence. validity has been questioned because...
The gastrointestinal tract harbors large and diverse populations of bacteria that vary among individuals within over time. Numerous internal external factors can influence the contents these microbial communities, including diet, geography, physiology, extent contact hosts. To investigate contributions such to variation changes in gut we analyzed distal microbiota individual chimpanzees from two communities Gombe National Park, Tanzania. These samples, which were derived 35 chimpanzees, many...
The most polymorphic part of the human genome, MHC, encodes over 160 proteins diverse function. Half them, including HLA class I and II genes, are directly involved in immune responses. Consequently, MHC region strongly associates with numerous diseases clinical therapies. Notoriously, has been intractable to high-throughput analysis at complete sequence resolution, current reference haplotypes inadequate for large-scale studies. To address these challenges, we developed a method that...
Promiscuous mating was traditionally thought to curtail paternal investment owing the potential costs of providing care unrelated infants. However, mounting evidence suggests that males in some promiscuous species can recognize offspring. In primates, for exists Cercopithecines, but less is known about these patterns other taxa. Here, we examine two hypotheses associations with lactating mothers eastern chimpanzees ( Pan troglodytes schweinfurthii ): effort, whereby associate and interact...
Like human immunodeficiency virus type 1 (HIV-1), simian of chimpanzees (SIVcpz) can cause CD4+ T cell loss and premature death. Here, we used molecular surveillance tools mathematical modeling to estimate the impact SIVcpz infection on chimpanzee population dynamics. Habituated (Mitumba Kasekela) non-habituated (Kalande) were studied in Gombe National Park, Tanzania. Ape sizes determined from demographic records or individual sightings genotyping (Kalande), while prevalence rates monitored...
Inbreeding adversely affects fitness, whereas heterozygosity often augments it. Therefore, mechanisms to avoid inbreeding and increase genetic distance between mates should be advantageous in species where adult relatives reside together. Here we investigate mate choice for dissimilarity chimpanzees, a which many females through dispersal, but promiscuous mating sexual coercion can limit when related adults We take advantage of incomplete female dispersal Gombe National Park, Tanzania...
Abstract Male chimpanzees (Pan troglodytes) defend group territories and sometimes kill members of rival communities — a pattern often compared to human warfare1-3. also grown males from their own community4-9. Such within-community killings are puzzling, as they reduce the coalition strength needed win inter-community contests5,10. Here we examine contexts killing using data two neighboring at Gombe National Park, Tanzania, well published other long-term chimpanzee study sites. At Gombe,...
To address claims of human exceptionalism, we determine where humans fit within the greater mammalian distribution reproductive inequality. We show that exhibit lower skew (i.e., inequality in number surviving offspring) among males and smaller sex differences than most other mammals, while nevertheless falling range. Additionally, female is higher polygynous populations nonhumans mammals on average. This patterning can be attributed part to prevalence monogamy compared predominance polygyny...
Abstract In social primates, individuals use various tactics to compete for dominance rank. Grooming, displays and contact aggression are common components of a male chimpanzee's repertoire. The optimal combination these behaviors is likely differ among males with exhibiting “style” that reflects their tendency cooperative and/or agonistic tactics. Here, we examine the grooming behavior three alpha chimpanzees at Gombe National Park, Tanzania. We found (1) differed significantly in groom...
Short tandem repeats (STRs), also known as microsatellites, are commonly used to noninvasively genotype wild-living endangered species, including African apes. Until recently, capillary electrophoresis has been the method of choice determine length polymorphic STR loci. However, this technique is labor intensive, difficult compare across platforms, and notoriously imprecise. Here we developed a MiSeq-based approach tested its performance using previously genotyped fecal samples from...
Faces provide important information about identity, age, and even kinship. A previous study in chimpanzees reported greater similarity between the faces of mothers sons compared with daughters, or unrelated individuals. This was interpreted as an inbreeding avoidance mechanism where females, dispersing gender, should avoid mating any male that resembles their mother. Alternatively, may be more distinctive than female faces, biasing attention toward males. To test these hypotheses, rhesus...
Major histocompatibility complex (MHC) class I molecules determine immune responses to viral infections. These polymorphic cell-surface glycoproteins bind peptide antigens, forming ligands for cytotoxic T and natural killer cell receptors. Under pressure from rapidly evolving viruses, hominoid MHC also evolve rapidly, becoming diverse species-specific. Little is known of the impact infectious disease epidemics on variant distributions in human populations, a context which chimpanzee superior...
