Abstract Demography provides critical data to increase our understanding of the evolution, ecology, and conservation primate populations. The chimpanzees Mahale Mountains National Park, Tanzania, have been studied for more than 34 yr on basis individual identification standardized attendance records. From this long‐term study, we derived following demographic data: major cause death was disease (48%), followed by senescence (24%) within‐species aggression (16%). Fifty percent died before...
One of the most conspicuous behavioural differences among great apes is paucity tool use wild bonobos ( Pan paniscus ) in comparison to chimpanzees troglodytes who are one prolific and skilled users animal kingdom. This spite fact that bonobo repertories as large diverse chimpanzees’ captive settings. In this study, we compared using behaviours potential drivers these Wamba population located central Democratic Republic Congo with Goualougo chimpanzee northern Congo. The repertoire was...
Abstract Objectives Although conflicts between groups over valuable resources are common in the animal kingdom, an individual's strategy toward out‐group individuals may differ according to benefits and costs received from inter‐group interactions. Groups of bonobos encounter each other frequently mingle range together a few hours days. During these associations, across exhibit both aggressive affiliative This study aimed examine strategies that employ with groups, by comparing patterns...
Understanding the habitat requirements of great apes is essential for effective conservation strategies. We examined annual use a bonobo group in Wamba field site within Luo Scientific Reserve, Democratic Republic Congo. Using satellite imagery, we categorized group's ranging area into three forest types: (1) primary and old secondary (P/OS), (2) young agriculture (YS/Ag), (3) swamp (Sw). tracked 1 year (2007-2008) compared usage types ranging, feeding, night-sleeping. also recorded what...
Bonobos (Pan paniscus) inhabit regions south of the Congo River including all areas between its southerly tributaries. To investigate genetic diversity and evolutionary relationship among bonobo populations, we sequenced mitochondrial DNA from 376 fecal samples collected in seven study populations located within eastern western limits species' range. In 136 effective different individuals (range: 7–37 per population), distinguished 54 haplotypes six clades (A1, A2, B1, B2, C, D), which...
Abstract Patterns of kinship among individuals in different groups have been rarely examined animals. Two closest living relatives humans, bonobos and chimpanzees share many characteristics social systems including male philopatry, whereas one major difference between the two species is nature intergroup relationship. Intergroup relationship basically antagonistic males sometimes kill other chimpanzees, it much more moderate copulations are often observed during encounters. Such behavioural...
Although both bonobos and chimpanzees are male-philopatric species, outcomes of male–male reproductive competition seem to be more closely associated with mating success in chimpanzees. This suggests that the extent male skew is lower bonobos. In addition, between-group lethal differentiation kinship We analysed paternity 17 offspring two bonobo groups estimated relatedness individuals among three neighbouring by using DNA extracted from non-invasive samples at Wamba, Democratic Republic...
The operational sex ratio (OSR) is used as a predictor for the intensity of mating competition. While many factors affect OSR, there tends to be high male bias in primate species with long interbirth intervals and non-seasonal breeding, such hominid apes. However, OSR bonobos (Pan paniscus) lower than that chimpanzees troglodytes), which thought reduce competitive aggressive behaviors. low considered result from early resumption female sexual receptivity during postpartum infertility they...
Great apes are considered to be important seed dispersers in palaeotropical habitats due their large body size (this would reflected the amount of foods consumed) and home ranges (Poulsen et al . 2001, Wrangham 1994). Furthermore, great might process seeds a way that maintains viability (Lambert 1999). Previous studies dispersal by have generally taken form lists found faeces (Voysey 1999a, 1994), effects passage through guts on germination (Idani 1986, location germination/seedling survival...
In general, studies on the diversity of strongylid nematodes in endangered host species are complicated as material obtained by non-invasive sampling methods has limited value for generic and identification. While egg morphology barely allows assignment to family, cultivated infective third stage larvae provides a better resolution at level but cannot be used exact Morphology-based taxonomic approaches greatly depend examination adult worms that usually not available.Hookworm parasites two...
We report here where the most recent common ancestor (MRCA) of bonobos (Pan paniscus) ranged and how they dispersed throughout their current habitat. Mitochondrial DNA (mtDNA) molecular dating to analyze time MRCA (TMRCA) major mtDNA haplogroups wild were performed using new estimations divergence from other Pan species investigate dispersal routes over forest area Congo River's left bank. The TMRCA was estimated be 0.64 or 0.95 million years ago (Ma). Six had very old origins 0.38 Ma older....
