Previous research suggests that the moment arm of the m. triceps surae tendon (i.e., Achilles tendon), is positively correlated with the energetic cost of running. This relationship is derived from a model which predicts that shorter ankle moment…

The influence of substrate compliance on gait mechanics has received little attention in previous studies of primate locomotion. Using high-speed video, we investigated how free-ranging platyrrhines in lowland Amazonian Ecuador adjust gait kinematics…

Arboreal mammals face unique challenges to locomotor stability. This is particularly true with respect to juveniles, who must navigate substrates similar to those traversed by adults, despite a reduced body size and neuromuscular immaturity.…

Locomotor features shared by arboreal marsupials and primates are frequently cited as a functional complex that evolved in the context of a "fine branch niche." Adaptation to a fine branch niche cannot be understood without considering that small and…

Physical anthropologists have devoted considerable attention to the structure and function of the primate prehensile tail. Nevertheless, previous morphological studies have concentrated solely on adults, despite behavioral evidence that among many…

Due to small body size, an immature musculoskeletal system, and other growth-related limits on performance, juvenile mammals frequently experience a greater risk of predation than their adult counterparts. As a result, behaviorally precocious…
