Biomechanical analyses of arboreal locomotion in great apes in their natural environment are scarce and thus attempts to correlate behavioural and habitat differences with variations in morphology are limited. The aim of this study was to investigate the gait characteristics of vertical climbing in mountain gorillas (Gorilla beringei beringei) and chimpanzees (Pan troglodytes) in a natural environment to assess differences in the climbing styles that may relate to variation in body size.

Figures and Tables from this paper

Functional signals and covariation in triquetrum and hamate shape of extant primates using 3D geometric morphometrics

TLDR
The results show that the carpal shape of quadrupedal anthropoids, which mainly use their wrist under compressive conditions, differs from that of suspensory primates as their wrist is possibly subjected to tensile and torsional forces.

Insertion sites in manual proximal phalanges of African apes and modern humans.

TLDR
The flexor ridges signal differences between taxa that use their hands for manipulation and locomotion (gorillas and chimpanzees) and taxas that use them exclusively for manipulation (humans).

Manual skills for food processing by mountain gorillas (Gorilla beringei beringei) in Bwindi Impenetrable National Park, Uganda

TLDR
This study only partly supports a functional link between diet and hand morphology in mountain gorillas and suggests that the gorilla hand is best adapted to forceful grasping that is required for both manipulation and arboreal locomotion.

A review of research in primate sanctuaries

TLDR
The range and form of research that has been conducted at accredited sanctuaries around the world are examined, including large, naturalistic physical and social environments which may result in more relevant models of primates' free-ranging wild counterparts than other captive settings.

Comparison of hand use and forelimb posture during vertical climbing in mountain gorillas (Gorilla beringei beringei) and chimpanzees (Pan troglodytes).

TLDR
Assessing differences in the climbing styles in wild, habituated mountain gorillas and semi-free-ranging chimpanzees found that both apes generally had the same grip preferences and used similar forelimb postures on supports of a similar size, which is consistent with their overall similarity in hard and soft tissue morphology of the hand and Forelimb.

Gait parameters in vertical climbing of captive, rehabilitant and wild Sumatran orang-utans (Pongo pygmaeus abelii)

TLDR
The spatio-temporal gait parameters of adult females carrying infants were not found to differ significantly from those for females without an infant, which suggests that climbing kinematics are not affected by the presence of a clinging infant.

Footfall Patterns, Stride Length and Speed of Vertical Climbing in Spider Monkeys (Ateles fusciceps robustus) and Woolly Monkeys (Lagothrix lagotricha)

TLDR
Results show that there are only few differences between gait parameters of climbing on thin trees, vertical and oblique ropes, while climbing on large-diameter trees differs considerably, reflecting the higher costs of locomotion on the latter.

Characteristics of vertical climbing in African apes

TLDR
3D-kinematics of vertical climbing in different hominoid species in zoos and the relationship between morphology and function in living apes will help to reconstruct the locomotor habits of fossil hominoids and early humans is described.

Gait characteristics and spatio‐temporal variables of climbing in bonobos (Pan paniscus)

TLDR
Bonobos take larger strides at lower stride frequencies and lower duty factors on a horizontal arboreal substrate than on a flat terrestrial substrate, and it is suggested that these changes are the result of the better grip of the grasping feet on an arborean substrate.

Exploring Diagonal Gait Using a Forward Dynamic Three-Dimensional Chimpanzee Simulation

TLDR
A biologically realistic computer simulations of primate gait that enable the constraints of biomechanical loading and the energetics of different modes of locomotion to be explored for the chimpanzee Pan troglodytes suggest that diagonal walking gaits in primates are selected for by multiple factors.

Locomotor energetics in primates: gait mechanics and their relationship to the energetics of vertical and horizontal locomotion.

TLDR
Results combining spatiotemporal and energetic data confirm and expand on the previous argument that similar costs of horizontal and vertical locomotion in small primates facilitated the successful occupation of a fine-branch arboreal milieu by the earliest primates.

TLDR
Analyses reveal that differences in climbing kinematics between individuals of different age/sex classes of one species are mostly size-related, whereas interspecific differences reflect specific locomotor adaptations in hominoids.

TLDR
Although no significant differences were found between sympatric baboons and chimpanzees in the proportion of time spent in the terminal branches, or in the mean diameter of weight-bearing strata, chimpanzees exhibited evidence of a terminal branch adaptation in that they, unlike baboons, used postures among smaller supporting strata different from those used among larger supports.
