| the phylogenetic relationships and classification of the doucs and snub-nosed langurs of china and vietnam. | the taxonomy of the douc and snub-nosed langurs has changed several times during the 20th century. the controversy over the systematic position of these animals has been due in part to difficulties in studying them: both the doucs and the snub-nosed langurs are rare in the wild and are generally poorly represented in institutional collections. this review is based on a detailed examination of relatively large numbers of specimens of most of the species of langurs concerned. an attempt was made t ... | 1993 | 8335292 |
| preliminary results from a field study of wild guizhou snub-nosed monkeys (rhinopithecus brelichi). | the guizhou snub-nosed monkey, rhinopithecus brelichi, is a large-bodied colobine confined to the subtropical semi-deciduous forests of fanjing mountain reserve in guizhou province, southwest china. field work beginning in 1979 and including 10 months of intensive study in 1991 has revealed several aspects of the behavior and ecology of this species that are distinct from other colobines, including the closely related species r. roxellana and r. bieti. the guizhou snub-nosed monkey is arboreal, ... | 1993 | 8335297 |
| reproductive parameters in guizhou snub-nosed monkeys (rhinopithecus brelichi). | in this study, we present data on reproductive parameters and birth seasonality of guizhou snub-nosed monkeys (rhinopithecus brelichi). our analyses are based on data from a small captive population collected over 15 years and on 5 years of observations of free-ranging snub-nosed monkeys. captive females (n=4) mature at an age of 70.8+/-6.7 months and reproduce for the first time at 103.4+/-7.5 months. the mean interbirth interval was 38.2+/-4.4 months if the infant survived more than 6 months, ... | 2009 | 19051322 |
| altitudinal movements of guizhou snub-nosed monkeys (rhinopithecus brelichi) in fanjingshan national nature reserve, china: implications for conservation management of a flagship species. | primate movements can include a substantial altitudinal component, depending on the complexity of the landscape and the distribution of the inherent vegetation zones. we investigated altitudinal movements of guizhou snub-nosed monkeys (rhinopithecus brelichi) at fanjingshan national nature reserve, china. the monkeys ranged at elevations between 1,350 and 1,870 m with an overall mean of 1,660 m. we did not find a significant difference in the mean elevations among seasons or evidence of winter m ... | 2010 | 21150211 |
| mitochondrial genome of the guizhou snub-nosed monkey (rhinopithecus brelichi). | the guizhou snub-nosed monkey (rhinopithecus brelichi) is an endangered species which is endemic to a small region in the fanjing mountain national nature reserve in guizhou province, china. in this study, we determined the complete mitochondrial genome of r. brelichi. the results showed that the total length of the mitogenome was 16,548 bp and contained 13 protein-coding genes, 22 transfer rna genes, two ribosomal rna genes and one control region. overall base composition of the complete mitoch ... | 2011 | 22165835 |
| Population genetic structure of Guizhou snub-nosed monkeys (Rhinopithecus brelichi) as inferred from mitochondrial control region sequences, and comparison with R. roxellana and R. bieti. | The Guizhou snub-nosed monkey (Rhinopithecus brelichi) is a primate species endemic to the Wuling Mountains in southern China. With a maximum of 800 wild animals, the species is endangered and one of the rarest Chinese primates. To assess the genetic diversity within R. brelichi and to analyze its genetic population structure, we collected fecal samples from the wild R. brelichi population and sequenced the hypervariable region I of the mitochondrial control region from 141 individuals. We compa ... | 2012 | 21953032 |
| into the night: camera traps reveal nocturnal activity in a presumptive diurnal primate, rhinopithecus brelichi. | most living primates exhibit a daytime or nighttime activity pattern. strict diurnality is thought to be the rule among anthropoids except for owl monkeys. here we report the diel activity pattern of an asian colobine, the guizhou snub-nosed monkey rhinopithecus brelichi, based on a methodology that relied on using 24-h continuously operating camera traps. we conducted the study in fanjingshan national nature reserve in guizhou, china from march 22 to may 19 and from june 17 to october 14, 2011. ... | 2013 | 22843040 |
| diet versus phylogeny: a comparison of gut microbiota in captive colobine monkey species. | both diet and host phylogeny shape the gut microbial community, and separating out the effects of these variables can be challenging. in this study, high-throughput sequencing was used to evaluate the impact of diet and phylogeny on the gut microbiota of nine colobine monkey species (n = 64 individuals). colobines are leaf-eating monkeys that fare poorly in captivity-often exhibiting gastrointestinal (gi) problems. this study included eight asian colobines (rhinopithecus brelichi, rhinopithecus ... | 2017 | 28735426 |
| genomic analysis of snub-nosed monkeys (rhinopithecus) identifies genes and processes related to high-altitude adaptation. | the snub-nosed monkey genus rhinopithecus includes five closely related species distributed across altitudinal gradients from 800 to 4,500 m. rhinopithecus bieti, rhinopithecus roxellana, and rhinopithecus strykeri inhabit high-altitude habitats, whereas rhinopithecus brelichi and rhinopithecus avunculus inhabit lowland regions. we report the de novo whole-genome sequence of r. bieti and genomic sequences for the four other species. eight shared substitutions were found in six genes related to l ... | 2016 | 27399969 |
| whole-genome sequencing of the snub-nosed monkey provides insights into folivory and evolutionary history. | colobines are a unique group of old world monkeys that principally eat leaves and seeds rather than fruits and insects. we report the sequencing at 146× coverage, de novo assembly and analyses of the genome of a male golden snub-nosed monkey (rhinopithecus roxellana) and resequencing at 30× coverage of three related species (rhinopithecus bieti, rhinopithecus brelichi and rhinopithecus strykeri). comparative analyses showed that asian colobines have an enhanced ability to derive energy from fatt ... | 2014 | 25362486 |
| a short note on extractive foraging behavior in gray snub-nosed monkeys. | extractive foraging (ef) involves the exploitation of hidden or embedded foods, generally any food that is not visible to the naked eye. therefore, ef is particularly important for survival in marginal habitats as it provides seasonal fallback foods in low food availability seasons. although many studies consider primates' ef behavior and category, colobine species are usually categorized as non-extractive foragers and few studies quantitatively examine their ef behavior. in this study, we exami ... | 2013 | 24344962 |
| genetic diversity in endangered guizhou snub-nosed monkeys (rhinopithecus brelichi): contrasting results from microsatellite and mitochondrial dna data. | to evaluate the conservation status of a species or population it is necessary to gain insight into its ecological requirements, reproduction, genetic population structure, and overall genetic diversity. in our study we examined the genetic diversity of rhinopithecus brelichi by analyzing microsatellite data and compared them with already existing data derived from mitochondrial dna, which revealed that r. brelichi exhibits the lowest mitochondrial diversity of all so far studied rhinopithecus s ... | 2013 | 24009761 |
| diet and feeding behavior of rhinopithecus brelichi at yangaoping, guizhou. | expectations of increases in human population growth and accelerated habitat loss, along with the realization that efforts to provide protection for ecosystems that sustain primates have met with limited success, make it critical that conservation plans are grounded firmly in scientific observation. studies of the diet breadth and feeding behavior of endangered species, therefore, are critical for understanding ecological adaptations and developing a conservation strategy. the diet and feeding e ... | 2012 | 22311194 |
| gut microbiota in wild and captive guizhou snub-nosed monkeys, rhinopithecus brelichi. | many colobine species-including the endangered guizhou snub-nosed monkey (rhinopithecus brelichi) are difficult to maintain in captivity and frequently exhibit gastrointestinal (gi) problems. gi problems are commonly linked to alterations in the gut microbiota, which lead us to examine the gut microbial communities of wild and captive r. brelichi. we used high-throughput sequencing of the 16s rrna gene to compare the gut microbiota of wild (n = 7) and captive (n = 8) r. brelichi. wild monkeys ex ... | 2019 | 31106872 |
