“…Rannala and Mountain (1997) described a similar statistical test for detecting immigration and identifying a likely source population for immigrants where population allele frequencies are estimated using Bayesian methods. Thus far, these tests have not been applied to primates, but they have been used to reveal identify dispersal patterns in other mammals (e.g., monogamous white-toothed shrews, Crocidura russula, Favre et al, 1997; white-footed mice, Peromyscus leucopus, Mossman and Waser, 1999).…”

In the past several decades, the development of novel molecular techniques and the advent of noninvasive DNA sampling, coupled with the ease and speed with which molecular analyses can now be performed, have made it possible for primatologists to directly examine the fitness effects of individual behavior and to explore how variation in behavior and social systems influences primate population genetic structure. This review describes the theoretical connections between individual behavior and primate social systems on the one hand and population genetic structure on the other, discusses the kinds of molecular markers typically employed in genetic studies of primates, and summarizes what primatologists have learned from molecular studies over the past few decades about dispersal patterns, mating systems, reproductive strategies, and the influence of kinship on social behavior. Several important conclusions can be drawn from this overview. First, genetic data confirm that, in many species, male dominance rank and fitness are positively related, at least over the short term, though this relationship need not simply be a reflection of malemale contest competition over mates. More importantly, genetic research reveals the significance of female choice in determining male reproductive success, and documents the efficacy of alternative mating tactics among males. Second, genetic data suggest that the presumed importance of kinship in structuring primate social relationships needs to be evaluated further, at least for some taxa such as chimpanzees in which demographic factors may be more important than relatedness. I conclude this paper by offering several suggestions of additional ways in which molecular techniques might be employed in behavioral and ecological studies of primates (e.g., for conducting "molecular censuses" of unhabituated populations, for studying disease and host-parasite interactions, or for tracking seed fate in studies of seed dispersal) and by providing a brief introduction to the burgeoning field of nonhuman primate behavioral genetics.

“…Another way to infer a bias in migration rates between males and females comes from the comparison of Wright's F st estimators computed both for males and females among sub-populations (Rassman et al, 1997;Balloux et al, 1998;Mossman and Waser, 1999). Indeed, F st is a parameter measuring the genetic differentiation (ie differences in allelic frequencies) between populations (Hartl and Clark, 1997).…”

Inferring sex-biased dispersal from population genetic tools: a review

2002

Sex-biased dispersal, where individuals of one sex stay or return to their natal site (or group) to breed while individuals of the other sex are prone to disperse, is a wide-spread pattern in vertebrate organisms. In general, mammals exhibit male-biased dispersal whereas birds exhibit female-bias. Dispersal estimates are often difficult to obtain from direct field observations. Here we describe different methods for inferring sex-specific dispersal using population genetic tools and discuss the problems they can raise. We distinguish two types of methods: those based on bi-parental markers (eg comparison of male/female relatedness, F st and assignment probabilities) and those relying on the comparison between

“…Several powerful approaches have been developed to detect individual dispersers through assignment tests or to characterize general patterns of dispersal through summary statistics of population genetic structure (F-statistics, relatedness). Most of these approaches utilize autosomal microsatellites as molecular markers, either alone (Mossman and Waser, 1999;Petit et al, 2001;Waser et al, 2001;Goudet et al, 2002) or in tandem with a uniparentally inherited marker such as mitochondrial DNA (mtDNA) or a Y-chromosome locus (Girman et al, 1997;Escorza-Trevino and Dizon, 2000). The expectation inherent to all these approaches is that greater genetic structure will be evident in the philopatric sex compared with the dispersing sex, thus comparisons of sex-specific F ST estimates should reveal the direction (and suggest the relative strength) of sex-bias in dispersal (Goudet et al, 2002).…”

Quantifying male-biased dispersal among social groups in the collared peccary (Pecari tajacu) using analyses based on mtDNA variation

Recent advances in the statistical analysis of microsatellite data permit calculation of sex-specific dispersal rates through sexand age-specific comparisons of genetic variation. This approach, developed for the analysis of data derived from codominant autosomal markers, should be applicable to a sexspecific marker such as mitochondrial DNA. To test this premise, we amplified a 449 bp control region DNA sequence from the mitochondrial genome of the collared peccary (Pecari tajacu), and estimated intra-class correlations among herds sampled from three Texas populations. Analyses on data partitioned by breeding group showed a clear signal of malebiased dispersal; sex-specific fixation indices associated with genetic variation among social groups within populations yielded values for females (F GP ¼ 0.91), which were significantly larger than values for males (F GP ¼ 0.24; P ¼ 0.0015). The same general pattern emerged when the analyses were conducted on age classes (albeit nonsignificantly), as well as categories of individuals that were predicted a posteriori to be dispersers (adult males) and philopatric (adult females and all immatures). By extending a previously published methodology based on biparentally inherited markers to matrilineally inherited haploid data, we calculated sex-specific rates of contemporary dispersal among social groups within populations (m # ¼ 0.37). These results support the idea that mitochondrial DNA haplotype frequency data can be used to estimate sex-specific instantaneous dispersal rates in a social species.
