“…The results of this study are consistent with preliminary field studies of wild Guinea baboons [Dunbar and Nathan, 1972;Galat-Luong et al, in press] and previous studies of this captive colony [Boese, 1975;Maestripieri et al, 2005] in suggesting that Guinea baboons have a harem-based mating system similar to that of hamadryas and gelada baboons. Specifically, in our captive group of 11 adult males and 23 adult females, some males copulated with a single female while others had harems of 2-4 females (see also the study by Maestripieri et al [2005], in which maximum har em size was 5 females).…”

Little is known about the mating system and social organization of Guinea baboons. This study investigated whether Guinea baboons have a harem-based mating system similar to that of hamadryas and gelada baboons and whether one-male mating units also correspond to social units. Ten adult females in a captive multi-male multi-female group of Guinea baboons were focally observed 2 h per week for 12 weeks, and all observed copulations within the group were recorded. Some males copulated with a single female while others had harems of 2–4 females. All females copulated with a single male except 1 female that switched harems early in the study. The focal females had higher rates of social interaction with their harem members, especially their harem male, than with individuals outside the harem. Females appeared to be subordinate to the harem male but little or no physical aggression or herding behavior from the male was observed. Variation in female social interactions within the harem was not accounted for by their sexual interactions with the male or their genetic relatedness with the females. Females, however, appeared to maintain social relationships with their female relatives in other harems. Taken together, the results of this study show that both mating and affiliative interactions in Guinea baboons are concentrated within one-male units and that the social dynamics within and between these units share some similarities as well as differences with those of hamadryas and gelada baboons.

The Influence of Social Systems on Patterns of Mitochondrial DNA Variation in Baboons

et al. 2013

Behavior is influenced by genes but can also shape the genetic structure of natural populations. Investigating this link is of great importance because behavioral processes can alter the genetic diversity on which selection acts. Gene flow is one of the main determinants of the genetic structure of a population and dispersal is the behavior that mediates gene flow. Baboons (genus Papio) are among the most intensely studied primate species and serve as a model system to investigate the evolution of social systems using a comparative approach. The general mammalian pattern of male dispersal and female philopatry has thus far been found in baboons, with the exception of hamadryas baboons (Papio hamadryas). As yet, the lack of data on Guinea baboons (Papio papio) creates a taxonomic gap in genus-wide comparative analyses. In our study we investigated the sex-biased dispersal pattern of Guinea baboons in comparison to hamadryas, olive, yellow, and chacma baboons using sequences of the maternally transmitted mitochondrial hypervariable region I. Analyzing whole-range georeferenced samples (N = 777), we found strong evidence for female-biased gene flow in Guinea baboons and confirmed this pattern for hamadryas baboons, as shown by a lack of genetic-geographic structuring. In addition, most genetic variation was found within and not among demes, in sharp contrast to the pattern observed in matrilocal primates including the other baboon taxa. Our results corroborate the notion that the Guinea baboons’ social system shares some important features with that of hamadryas baboons, suggesting similar evolutionary forces have acted to distinguish them from all other baboons.Electronic supplementary materialThe online version of this article (doi:10.1007/s10764-013-9725-5) contains supplementary material, which is available to authorized users.

“…Interbreeding may also occur between western olive and Guinea baboons in Mauretania, Mali, Guinea and even in Ivory Coast (TahiriZagrët 1976, Galat-Luong et al 2006. Until recently, it was assumed that Kinda baboons and chacmas are parapatric or only marginally sympatric, and evidence for interbreeding was lacking (Machado 1969, Ansell 1978.…”

Baboons of the genus Papio have colonised wide areas of Africa and parts of the Arabian Peninsula. Traditionally, 5 phenotypically distinct morphotypes (species) are recognised: chacma baboons, yellow baboons, olive baboons, Guinea baboons and hamadryas baboons. We used mitochondrial DNA ("Brown" region) sequence data obtained mainly from faecal samples collected across the geographical range of baboons to reconstruct their phylogenetic relationships. Eight well-supported major haplogroups were detected, which reflect geographic populations. These disagree with the traditional classification of baboons into only 5 taxa. We found that West African olive and chacma baboons both comprise at least two deeply separated clades. In the case of chacma baboons, they correspond to recognised morphotypes (Cape chacma and grey-footed chacma). Our data also support a previously suggested distinction between yellow and Kinda baboons from central Zambia. Two other terminal clades from eastern Africa comprise either eastern olive and hamadryas baboons or eastern olive and yellow baboons. Southern yellow baboons cluster with grey-footed chacma baboons. Our data also indicate a possible mitochondrial overlap between Guinea baboons and a particular lineage of western olive baboons from Ivory Coast. These results support recent molecular studies, which detected several para-and polyphyletic mitochondrial clades in Papio, suggesting that the evolutionary history of baboons is even more complicated than previously thought. Thus, important roles might have been played by multiple phases of fragmentation, isolation, hybridisation, introgression, and nuclear swamping, hence, reticulation. These processes were most likely triggered by multiple cycles of expansion and retreat of savannah biomes during late Pliocene and Pleistocene glacial and inter-glacial periods. We also speculate on the likely dispersal pathways of these primates that may have led to their current distribution.
