| seed dispersal by long-tailed macaques. | we review here the methods by which long-tailed macaques (macaca fascicularis fascicularis) process seeds in bukit timah nature reserve, singapore, and the factors that influence this. feeding observations have revealed that these macaques either destroy seeds in their mouth with their teeth, spit them out whole from the mouth after removing much of the flesh, or else clean the flesh off them at the front of the mouth and then drop them. absence of these observed behaviors is associated with the ... | 1998 | 9573441 |
| factors shaping genetic variation in the mhc of natural non-human primate populations. | across a large distribution range, population-specific factors as well as pathogen-mediated selection may shape species genetic diversity in the major histocompatibility complex (mhc). we have studied genetic diversity and population differentiation in the mhc region of the southeast asian cynomolgus macaque (macaca fascicularis fascicularis), a species with large and discontinuous range, in order to investigate the role of demography vs selection. genetic variation was assessed at seven mhc mic ... | 2007 | 17854428 |
| mitochondrial dna sequence phylogeny of 4 populations of the widely distributed cynomolgus macaque (macaca fascicularis fascicularis). | we studied the mitochondrial dna (mtdna) polymorphism of 304 macaca fascicularis fascicularis (m. f. fascicularis) individuals, representative of 4 cynomolgus macaque populations (indochina, indonesia, philippines, and mauritius). by sequencing a 590-bp fragment in the hypervariable ii region of the d-loop region, we defined 70 haplotypes. the homologous region was also characterized in 22 chinese macaca mulatta and 2 macaca sylvanus. the phylogenetic analysis confirms the monophyly of m. f. fas ... | 2008 | 18334507 |
| mitochondrial dna and two y-chromosome genes of common long-tailed macaques (macaca fascicularis fascicularis) throughout thailand and vicinity. | macaca fascicularis fascicularis is distributed over a wide area of southeast asia. thailand is located at the center of their distribution range and is the bridge connecting the two biogeographic regions of indochina and sunda. however, only a few genetic studies have explored the macaques in this region. to shed some light on the evolutionary history of m. f. fascicularis, including hybridization with m. mulatta, m. f. fascicularis and m. mulatta samples of known origins throughout thailand an ... | 2017 | 27643851 |
| mitogenomic phylogeny of the common long-tailed macaque (macaca fascicularis fascicularis). | long-tailed macaques (macaca fascicularis) are an important model species in biomedical research and reliable knowledge about their evolutionary history is essential for biomedical inferences. ten subspecies have been recognized, of which most are restricted to small islands of southeast asia. in contrast, the common long-tailed macaque (m. f. fascicularis) is distributed over large parts of the southeast asian mainland and the sundaland region. to shed more light on the phylogeny of m. f. fasci ... | 2015 | 25887664 |
| continental monophyly and molecular divergence of peninsular malaysia's macaca fascicularis fascicularis. | the phylogenetic relationships of long-tailed macaque (macaca fascicularis fascicularis) populations distributed in peninsular malaysia in relation to other regions remain unknown. the aim of this study was to reveal the phylogeography and population genetics of peninsular malaysia's m. f. fascicularis based on the d-loop region of mitochondrial dna. sixty-five haplotypes were detected in all populations, with only vietnam and cambodia sharing four haplotypes. the minimum-spanning network projec ... | 2014 | 25143948 |
| microsatellite variation in two subspecies of cynomolgus monkeys (macaca fascicularis). | to estimate the genetic variability of two subspecies of cynomolgus monkeys (macaca fascicularis fascicularis and m. f. aurea) using microsatellite markers, 26 microsatellite markers were selected from previous reports. seventeen markers showed high polymorphism in a subset of monkeys and were used for the assessment of genetic diversity in the larger sample. the effective number of alleles, the polymorphism information content (pic) and the expected heterozygosity of m. f. aurea monkeys were al ... | 2012 | 22539270 |
| naive, captive long-tailed macaques (macaca fascicularis fascicularis) fail to individually and socially learn pound-hammering, a tool-use behaviour. | a subspecies of long-tailed macaques (macaca fascicularis aurea; mfa) has been reported to use stone tools and a specific technique to process nuts in southeast asia, a behaviour known as 'pound-hammering'. the aim of this study was to examine the development of pound-hammering in long-tailed macaques: whether this behavioural form can be individually learnt or whether it has to rely on some forms of social learning. given the absence of mfa from captivity, long-tailed macaques of a highly relat ... | 2018 | 29892375 |
| whole mitochondrial genomic and y-chromosomal phylogenies of burmese long-tailed macaque (macaca fascicularis aurea) suggest ancient hybridization between fascicularis and sinica species groups. | macaca fascicularis aurea (burmese long-tailed macaque) is 1 of the 10 subspecies of macaca fascicularis. despite having few morphological differences from other subspecies, a recent phylogeographic study showed that m. f. aurea is clearly distinct genetically from macaca fascicularis fascicularis (common long-tailed macaque) and suggests that m. f. aurea experienced a disparate evolutionary pathway versus other subspecies. to construct a detailed evolutionary history of m. f. aurea and its rela ... | 2018 | 29186474 |
