EXPLORING THE FEEDING PATTERNS OF SIAMANGS: BEHAVIOR AND FOOD PREFERENCES IN ZOO ENVIRONMENTS AND THEIR CONTRIBUTION TO BIOLOGY EDUCATION
Bio-Lectura : Jurnal Pendidikan Biologi; Vol. 12 No. 1 (2025); 41-56
The siamang (Symphalangus syndactylus), an endemic primate of Indonesia, is critically endangered due to hunting and habitat destruction and is now predominantly found in conservation areas. This study aims to analyze the feeding behavior and food pr...

Molecular phylogeny confirms the subspecies delineation of the Malayan Siamang (Symphalangussyndactyluscontinentis) and the Sumatran Siamang (Symphalangussyndactylussyndactylus) based on the hypervariable region of mitochondrial DNA
Biodivers Data J
Siamangs (Symphalangussyndactylus) are native to Peninsular Malaysia, Sumatra and southern Thailand and their taxonomical classification at subspecies level remains unclear. Morphologically, two subspecies were proposed as early as 1908 by Thomas nam...

Repetitive sequences originating from the centromere constitute large-scale heterochromatin in the telomere region in the siamang, a small ape
Heredity (Edinb)
Chromosomes of the siamang Symphalangus syndactylus (a small ape) carry large-scale heterochromatic structures at their ends. These structures look similar, by chromosome C-banding, to chromosome-end heterochromatin found in chimpanzee, bonobo and go...

Sleeping trees and sleep-related behaviours of the siamang (Symphalangus syndactylus) in a tropical lowland rainforest, Sumatra, Indonesia
Primates
Sleeping tree selection and related behaviours of a family group and a solitary female siamang (Symphalangus syndactylus) were investigated over a 5-month period in northern Sumatra, Indonesia. We performed all day follows, sleeping tree surveys and ...

SPECIES-SPECIFIC DISTRIBUTIONS OF TYROSINE HYDROXYLASE-IMMUNOREACTIVE NEURONS IN THE PREFRONTAL CORTEX OF ANTHROPOID PRIMATES
Neuroscience
In this study, we assessed the distribution of cortical neurons immunoreactive for tyrosine hydroxylase (TH) in prefrontal cortical regions of humans and nonhuman primate species. Immunohistochemical methods were used to visualize TH-immunoreactive (...

Muscle moment arms and function of the siamang forelimb during brachiation
J Anat
Moment arms have an important modulating impact on muscle function, as they represent the capacity of the muscle to convert muscle action into limb movements. In the current paper, we provide muscle moment arm data of the forelimb of four siamangs, c...

Evolutionary Origin of Higher-Order Repeat Structure in Alpha-Satellite DNA of Primate Centromeres
DNA Res
Alpha-satellite DNA (AS) is a main DNA component of primate centromeres, consisting of tandemly repeated units of ∼170 bp. The AS of humans contains sequences organized into higher-order repeat (HOR) structures, in which a block of multiple repeat ...

A toolkit for the dynamic study of air sacs in siamang and other elastic circular structures
PLoS Comput Biol
Biological structures are defined by rigid elements, such as bones, and elastic elements, like muscles and membranes. Computer vision advances have enabled automatic tracking of moving animal skeletal poses. Such developments provide insights into co...

A molecular phylogeny of the hominoid primates as indicated by two-dimensional protein electrophoresis.
Proc Natl Acad Sci U S A
A molecular phylogeny for the hominoid primates was constructed by using genetic distances from a survey of 383 radiolabeled fibroblast polypeptides resolved by two-dimensional electrophoresis (2DE). An internally consistent matrix of Nei genetic dis...

Integration-free induced pluripotent stem cells from three endangered Southeast Asian non-human primate species
Sci Rep
Advanced molecular and cellular technologies provide promising tools for wildlife and biodiversity conservation. Induced pluripotent stem cell (iPSC) technology offers an easily accessible and infinite source of pluripotent stem cells, and have been ...

Resolution of the African hominoid trichotomy by use of a mitochondrial gene sequence.
Proc Natl Acad Sci U S A
Mitochondrial DNA sequences encoding the cytochrome oxidase subunit II gene have been determined for five primate species, siamang (Hylobates syndactylus), lowland gorilla (Gorilla gorilla), pygmy chimpanzee (Pan paniscus), crab-eating macaque (Macac...

Non-canonical DNA in human and other ape telomere-to-telomere genomes
bioRxiv
Non-canonical (non-B) DNA structures—e.g., bent DNA, hairpins, G-quadruplexes (G4s), Z-DNA, etc.—which form at certain sequence motifs (e.g., A-phased repeats, inverted repeats, etc.), have emerged as important regulators of cellular processes an...

Orangutan Alu quiescence reveals possible source element: support for ancient backseat drivers
Mob DNA
BACKGROUND: Sequence analysis of the orangutan genome revealed that recent proliferative activity of Alu elements has been uncharacteristically quiescent in the Pongo (orangutan) lineage, compared with all previously studied primate genomes. With rel...

Evolutionary Glycomics: Characterization of Milk Oligosaccharides in Primates
J Proteome Res
Free oligosaccharides are abundant components of mammalian milk and have primary roles as prebiotic compounds, in immune defense, and in brain development. Mass spectrometry-based technique is applied to profile milk oligosaccharides from apes (chimp...

Interspecific variation in the diet of Symphalangussyndactylus and Macacanemestrina at Genting Highlands, Pahang, Peninsular Malaysia
Biodivers Data J
Primate communities in the Genting Highlands consist of a single species of Hylobatidae and four species of Cercopithecidae, which are known to exhibit social interaction behaviour. Thus, a study on the diets of Symphalangussyndactylus (siamang; fami...

Anatomical Contributions to Hylobatid Taxonomy and Adaptation
Int J Primatol
Compared with the great apes, the small-bodied hylobatids were treated historically as a relatively uniform group with 2 genera, Hylobates and the larger-bodied Symphalangus. Four genera are now recognized, each with a different chromosome number: Ho...

Comparative Analyses of Gibbon Centromeres Reveal Dynamic Genus-Specific Shifts in Repeat Composition
Mol Biol Evol
Centromeres are functionally conserved chromosomal loci essential for proper chromosome segregation during cell division, yet they show high sequence diversity across species. Despite their variation, a near universal feature of centromeres is the pr...
