“…More haplogroups were detected among FE groups than were previously reported for RC groups 12 (Supplementary Table 6). Although, the same East Asian and Southeast Asian haplogroups previously observed for RC groups (B4, B5, D, E, F, R9, M7 and Y) 12 also were observed among FE groups, but with differences in the array of haplogroup sublineages (Supplementary Table 6). MDS analysis shows that HVS-1 sequences of RC groups appear to be in the middle of FE groups in this study (Figure 2c).…”

“…A separate MDS analysis (data not shown) of complete mtDNA genomes of FE groups and 30 complete mtDNA genomes of undefined geographical origins and/or FE group affiliation, 12 showed the same MDS plot position for the 'Undefined' Filipino group as in Figure 2c. CA (Figure 2d) shows that RC groups (including the 'Undefined' group) are close to most FE groups in the first dimension of the plot, with the association driven by common haplogroups (B4a1a, E1a1a and M7c3c).…”

“…12,24 Overall, BEs of haplogroup coalescent times for FE groups extend from about 2800 years ago (2. Table 5) show that the female N e are but a fraction of the actual group sizes with groups such as the AetaZ and the Agta having very low N e .…”

“…Complete mtDNA genomes of Filipino ethnolinguistic F Delfin et al FE group mtDNA and Filipino RC group mtDNA The Luzon, Visayas and Mindanao groups, who were previously surveyed using mtDNA HVS data, 12 can be considered RC groups because individuals were sampled in regional centers. More haplogroups were detected among FE groups than were previously reported for RC groups 12 (Supplementary Table 6).…”

“…Mitochondrial DNA (mtDNA) diversity based on the hypervariable segment (HVS) and complete mtDNA genomes of Filipinos from three regional centers, each within the main Philippine islands of Luzon, Visayas and Mindanao show support for the 'Out of Taiwan' theory for the expansion of the Austronesian language family. 12 Next-generation sequencing methods allowed an unbiased, population-based survey of complete mtDNA genomes revealing novel and ancient mtDNA lineages as well as different demographic histories (effective population size (N e ) changes) among three FE groups. 13 A survey of the non-recombining region of the Y-chromosome (NRY) reveal extensive heterogeneity with different ancient and recent genetic affinities for 16 FE groups.…”

The Maldives are an 850 km-long string of atolls located centrally in the northern Indian Ocean basin. Because of this geographic situation, the present-day Maldivian population has potential for uncovering genetic signatures of historic migration events in the region. We therefore studied autosomal DNA-, mitochondrial DNA-, and Y-chromosomal DNA markers in a representative sample of 141 unrelated Maldivians, with 119 from six major settlements. We found a total of 63 different mtDNA haplotypes that could be allocated to 29 mtDNA haplogroups, mostly within the M, R, and U clades. We found 66 different Y-STR haplotypes in 10 Y-chromosome haplogroups, predominantly H1, J2, L, R1a1a, and R2. Parental admixture analysis for mtDNA- and Y-haplogroup data indicates a strong genetic link between the Maldive Islands and mainland South Asia, and excludes significant gene flow from Southeast Asia. Paternal admixture from West Asia is detected, but cannot be distinguished from admixture from South Asia. Maternal admixture from West Asia is excluded. Within the Maldives, we find a subtle genetic substructure in all marker systems that is not directly related to geographic distance or linguistic dialect. We found reduced Y-STR diversity and reduced male-mediated gene flow between atolls, suggesting independent male founder effects for each atoll. Detected reduced female-mediated gene flow between atolls confirms a Maldives-specific history of matrilocality. In conclusion, our new genetic data agree with the commonly reported Maldivian ancestry in South Asia, but furthermore suggest multiple, independent immigration events and asymmetrical migration of females and males across the archipelago.

Spatio-temporal migration patterns to and from an upland village of Mindanao, Philippines

Movement of groups of people is closely linked to environmental, agricultural and cultural change. Gaining an understanding of these changes in a local context is a vital prelude to the construction of a viable predictive model. We carried out a study in the Philippines to better understand the association between migration and these types of changes at a village scale and to build a picture of how the associations changed in time and space. The study area was located in the uplands of Mindanao. Migration to the village began in the late 1970s. As of 2010, the population is made up of indigenous people (*57 %), people who migrated from elsewhere in the Philippines (*29 %), and descendants of indigenous/non indigenous parents (*14 %). Face-to-face interviews in the village and in the places of origin/destination were used to collect qualitative information on the migrations made by the current and past village inhabitants. The main results relate to the reasons for migration, the socioenvironmental processes that induced the decision to move and the description and explanation of more recent moves. The local findings are discussed in the context of existing published models of migration in frontier areas.
