Locomotion and posture of the Malayan siamang and implications for hominoid evolution.
TLDR
Comparison of siamang locomotion and posture with that of other apes suggest that quadramanous climbing during feeding is the basic hominoid locomotor adaptation.Abstract:
Wild, adult siamang were observed for over 800 h in lowland dipterocarp forest in the Krau Game Reserve, Pahang, West Malaysia. Siamang use four patterns of locomotion: brachiation, climbing, bipedalism and leaping. The pattern of locomotion used by the siamang varies with the size of arboreal supports and with major behavioral activity. Travel is primarily by brachiation along large boughs. Locomotion during feeding is primarily climbing among small branches. In feeding, siamang use suspensory postures among small supports and seated postures on large supports. Comparison of siamang locomotion and posture with that of other apes suggest that quadramanous climbing during feeding is the basic hominoid locomotor adaptation.read more

Locomotor behavior, body size, and comparative ecology of seven Surinam monkeys
TL;DR: There are no consistent associations between diet and either locomotor behavior or forest utilization; rather, monkeys with similar diets show locomotor and habitat differentiation.

Standardized descriptions of primate locomotor and postural modes

TL;DR: 32 primate positional modes are defined, divided more finely into 52 postural sub-modes and 74 locomotor sub-Modes, and a nomenclature is recommended that is not dedicated to or derived from any one taxonomic subset of the primates.

Habitat preferences, diet, feeding strategy and social organization of the black spider monkey (Ateles paniscus paniscus Linnaeus 1758) in Surinam
TL;DR: This monograph reports on a 26 month socioecological study of black spider monkeys in the Raleigh-vallen — Voltzberg Nature Reserve, Surinam, and clarifies the complex temporal and spatial effects of tropical rain forest food sources on the behavior of a group of spider monkeys.

Body Size and Scaling of Limb Proportions in Primates
TL;DR: It is reasonable to wonder if the linear dimensions of the long bones of adult primates also conform to the expectations of geometric similarity, and if this null hypothesis for primate limb proportions forGalagos and tarsiers simply do not resemble gibbons or gorillas very much with regard to their respective bodily proportions.
