“…Male exchange between groups and solitary wandering of both sexes has been observed but natal dispersal has not been adequately described (Ellisor and Harwell, 1969;Day, 1985;Gabor and Hellgren, 2000). Earlier little population genetic data existed for P. tajacu (but see Gongora et al, 2006). Theimer and Keim (1994) utilized mtDNA variation to measure sequence divergence and geographic partitioning in Arizona populations, but their samples were not associated with social groups.…”

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.

“…Identification: Specimens of Pecari tajacu collected in the Yavarí-Ucayali interfluve externally resemble the widespread Amazonian phenotype (Husson, 1978;Emmons 1997), and craniodental measurements of our material (table 17) broadly overlap those of Surinamese specimens (Husson, 1978: Analyses of mtDNA control region sequences (Gongora et al, 2006(Gongora et al, , 2011 suggest the existence of two moderately well-supported phylogroups of Pecari tajacu, consisting of predominantly North American and Central American sequences on the one hand and of South American sequences on the other. Unfortunately, the relevance of this analytic result for assessing the plethora of currently recognized subspecies (Grubb, 2005) is unclear, because no sequence data are available from the type localities of several key nominal taxa, including the nominotypical form (restricted by convention to Pernambuco, Brazil;Cabrera, 1961;Hershkovitz, 1963).…”

“…More detailed molecular studies suggest that the collared peccary might well comprise two clades, one in South America and one in Central America, with a possible hybrid zone in Colombia (Gongora et al, 2006). The two clades of collared peccaries might possibly rank as two species because genetically they are as distinct as are the white-lipped and Chacoan peccaries (Gongora et al, 2006). Molecular divergence time estimates by Theimer and Keim (1998) suggested that the collared peccary lineage split from that of the white-lipped and Chacoan peccaries~7.4-3.4 Ma, whereas Gongora and Moran (2005) suggested two possible age ranges for this event, 7.7-6.2 Ma and 13.2-4.3 Ma.…”

Two new, extinct taxa of peccaries from upper Miocene deposits of the western Amazon Basin provide the first data documenting the presence of these North American mammals in South America in the Miocene. One, Sylvochoerus woodburnei n. gen. n. sp., is allied morphologically to Tayassu pecari, whereas the second, Waldochoerus bassleri n. gen. n. sp., is more similar to Pecari tajacu. Both new taxa reflect an intermediate position between middle Miocene peccaries and modern Tayassu and Pecari. The specimens reported here were unstudied, but when collected they were referred to living species of Tayassu and Pecari based on their general similarity to species of those two living genera, and they were dated to the Pleistocene, presumably based on a long–standing model of the Great American Faunal Interchange. The presence of peccaries in South America at approximately the same time that South American ground sloths began appearing in upper Miocene deposits of North America, and soon after the appearance of gomphotheres in South America, indicates that dispersal between the Americas was earlier and involved more taxa than previously interpreted. Molecular divergence data are consistent, in part, with a late Miocene dispersal of peccaries to South America.
