“…Saudi Arabia indicates an older colonisation event (Wildman et al, 2004), perhaps via the land bridge which formed across the Strait of Bab el Mandeb, 85-119 kya (Winney et al, 2004). We found only slightly lower values of allelic richness at five out of six autosomal loci and at one Y-linked locus in an Arabian (Abha, Saudi Arabia) compared to an African population (Filwoha, Ethiopia; Table 4), and no difference between the two populations in mean allelic richness.…”

Low Y chromosome variation in Saudi-Arabian hamadryas baboons (Papio hamadryas hamadryas)

It is important to characterise the amount of variation on the mammalian Y chromosome in order to assess its potential for use in evolutionary studies. We report very low levels of polymorphism on the Y chromosome of Saudi-Arabian hamadryas baboons, Papio hamadryas hamadryas. We found no segregating sites on the Y, despite sequence analysis of 3 kb noncontiguous intron sequence in 16 males with divergent autosomal microsatellite genotypes, and a further analysis of 1.1 kb intron sequence in 97 males from four populations by SSCP. In addition, we tested seven human-derived Y-linked microsatellites in baboons. Only four of these loci were male-specific and only one was polymorphic in our 97 male sample set. Polymorphism on the Y chromosome of Arabian hamadryas appears to be low compared to other primate species for which data are available (eg humans, chimpanzees and bonobos). Low effective population size (Ne) of paternal genes due to polygyny and female-biased adult sex ratio is a potential reason for low Y chromosome variation in this species. However, low Ne for the Y should be counterbalanced to some extent by the species' atypical pattern of male philopatry and female-biased dispersal. Allelic richness averaged over seven loci was not significantly different between an African and an Arabian population, suggesting that loss of variation during the colonisation of Arabia does not explain low Y variation. Finally, in the absence of nucleotide polymorphism, it is unclear to what extent selection could be responsible for low Y variation in this species.

“…Arabian hamadryas are thought to have African ancestry (Kummer et al, 1981;Wildman et al, 2004;Winney et al, 2004). If a founder event during colonisation has contributed to low Y chromosome variation in Saudi Arabia, we also expect lower variation at autosomal loci in Arabian compared to African populations.…”

“…Of the 298 individuals 99.0% were of known sex and 87.2% were of known age. Details of how animals were sexed and aged, DNA samples collected and DNA extracted are given in Hammond et al (submitted) and Winney et al (2004). Hamadryas social structure is based on the 'one male unit' (OMU), which consists of an adult leader male, several adult females and juvenile and infant offspring.…”

“…Weir & Cockerham's (1984) estimate of F st was calculated over all populations in FSTAT for each of the three genomic regions (Y, mtDNA and autosomes). For mtDNA, F st was calculated based on haplotype frequencies for a sample of 107 males and females (Abha, nZ72; Baha, nZ14; Taif, nZ15; Al-Akhal, nZ6) as described in Winney et al (2004). …”

“…Pusey 1987;Pusey & Packer 1987;Stammbach 1987), however, observations of male dispersal have also been documented (Kummer 1968;Phillips-Conroy et al 1992), and some authors have suggested that sex-biased dispersal is limited to local scales and so of little significance in hamadryas baboons (Sigg et al 1982;Abbeglen 1984;Henzi & Barrett 2003;Yamane et al 2003). Recently, it has been argued that low levels of population genetic differentiation for mitochondrial DNA (mtDNA) are consistent with female dispersal (Hapke et al 2001;Winney et al 2004), but without analysis of paternal and/or biparental markers it is impossible to reject the possibility of equal or greater male dispersal. The uncertainty as to whether dispersal is truly female biased is reflected by influential papers on the evolution of dispersal where hamadryas baboons have been categorized as exhibiting either female biased (Marks & Redmond 1987;Pusey 1987) or unbiased dispersal (Greenwood 1980;Dobson 1982;Clutton-Brock 1989).…”

Genetic evidence for female-biased dispersal and gene flow in a polygynous primate

Many models of sex-biased dispersal predict that the direction of sex-bias depends upon a species' mating system. In agreement with this, almost all polygynous mammals show male-biased dispersal whereas largely monogamous birds show female-biased dispersal (FBD). The hamadryas baboon (Papio hamadryas hamadryas) is polygynous and so dispersal is predicted to be male biased, as is found in all other baboon subspecies, but there are conflicting field data showing both female and male dispersal. Using 19 autosomal genetic markers genotyped in baboons from four Saudi Arabian populations, we found strong evidence for FBD in post-dispersal adults but not, as expected, in pre-dispersal infants and young juveniles, when we compared male and female: population structure (F st ), inbreeding (F is ), relatedness (r), and the mean assignment index (mAIc). Furthermore, we found evidence for female-biased gene flow as population genetic structure (F st ), was about four times higher for the paternally inherited Y, than for either autosomal markers or for maternally inherited mtDNA. These results contradict the direction of sex-bias predicted by the mating system and show that FBD has evolved recently from an ancestral state of male-biased dispersal. We suggest that the cost-benefit balance of dispersal to males and females is tightly linked to the unique hierarchical social structure of hamadryas baboons and that dispersal and social organization have coevolved.

The golden monkey (Rhinopithecus roxellana) is one of the most endangered primate species due to its dramatically shrinking distribution during the past 400 years. Its populations are restricted to three isolated regions, Qinglin (QL), Sichuan/Gansu (SG), and Shennongjia (SNJ) in China. As with other snub-nosed monkeys in China and Vietnam, the biology and evolution of this species is still poorly known. To assess genetic differentiation and explore the relationships among populations of golden monkeys from different geographic locations, 379 bp of mitochondrial DNA control region (CR) hypervariable segment I (HVI) was studied from 60 individuals. Twelve haplotypes were identified from seven populations within the three regions. Haplotype diversity was high (0.845), whereas nucleotide diversity among all haplotypes was low (0.0331). The most recent common ancestor (TMRCA) among mtDNA haplotypes was estimated to have lived approximately 0.48-0.32 million years ago. None of the haplotypes is shared among any of the three regions. Phylogenetic analysis and AMOVA revealed clear and significant phylogeographic structure between the three regions. However, only SG contained haplotypes of the two main clades, indicating either incomplete random sorting of haplotypes or a complex history with phases of population subdivisions and merging of populations. The phylogeographic structure implies that R. roxellana should be regarded as separate management units (MUs) for each of the three regions. It is likely that recent phylogeographic history has shaped the pattern of genetic differentiation observed in the golden monkey and that its populations have suffered significant demographic fluctuation.
