How do rivers, geographic distance, and dispersal behavior influence genetic structure in two sympatric New World monkeys
Dispersal, one of the major factors affecting the gene flow between populations, shapes the spatial distribution of genetic diversity within species. Alouatta macconnelli and Saguinus midas are two Neotropical monkey species that sympatrically inhabit the Guiana shield in northern Amazonia and are likely to differ in their dispersal behavior and vagility. We took advantage of their sympatry to investigate, over a fine geographical scale (∼50 km l…
Spatial variation in density and total size estimates in fragmented primate populations
The golden‐crowned sifaka ( Propithecus tattersalli ) is an endangered lemur species found only in the Daraina region, a very restricted area in north‐eastern Madagascar. Its forest habitat is highly fragmented and expected to suffer from significant changes in the near future. The species is poorly known and only one census study, carried out in 2000, has ever been published. It is thus crucial to update the conservation status of the golden‐cro…
Multiple Displacement Amplification for Generating an Unlimited Source of DNA for Genotyping in Nonhuman Primate Species
Multiplexed microsatellites for rapid identification and characterization of individuals and populations of Cercopithecidae
Cross-amplification of 15 human microsatellites was performed successfully in cynomolgus (Macaca fascicularis) and rhesus (M. mulatta) macaques and 11 other Cercopithecidae species of biomedical and conservation relevance. To allow for quick, efficient, and high-throughput genotyping to assess intra- and interspecific genetic variation, we performed three multiplex sets, each comprised of five markers from different parts of the genome (i.e., aut…
GM haplotype diversity of 82 populations over the world suggests a centrifugal model of human migrations
This study investigates the GM genetic relationships of 82 human populations, among which 10 represent original data, within and among the main broad geographic areas of the world. Different approaches are used: multidimensional scaling analysis and test for isolation by distance, to assess the correlation between genetic variation and spatial distributions; analysis of variance, to investigate the genetic structure at different hierarchical leve…
Microsatellite DNA markers from HLA region ( D6S105, D6S265 and TNFa ) in autochthonous Basques from Northern Navarre (Spain)
Findings shown here on HLA microsatellites and their relationships with other HLA class I and class II genes in Basques can be helpful for those studies mainly addressed at detecting associations between HLA genes and diseases in the Basque area as a whole, and particularly in its autochthonous population, settled there since remote times
Testing the reliability of noninvasive genetic sampling by comparing analyses of blood and fecal samples in Barbary macaques ( Macaca sylvanus )
Genetic studies of wild animal populations are often hindered by difficulties in obtaining blood samples. Recent advances in molecular biology have allowed the use of noninvasive samples as sources of DNA (e.g., hair or feces), but such samples may provide low‐quality DNA and prevent the determination of true genotypes in subsequent DNA analysis. We present a preliminary study aimed at assessing the reliability of using fecal samples for genotypi…
Conservation and evolution of microsatellite loci in primate taxa
Microsatellites are promising genetic markers for the study of demographic structure and phylogenetic history in populations. However, little information exists on the molecular nature of the repeats and their flanking sequences of a same microsatellite in a large range of species. In this study, we report polymorphism and consensus sequences of eight microsatellite loci using human primers in 20 primate species. The results show size polymorphis…
