Positional behavior and habitat use of Peters’ Angola black and white colobus monkey (Colobus angolensis palliatus) in structurally distinct areas of the Diani Forest, Kenya
Positional behavior is the manifestation of both evolutionary and ecological influences. While a number of studies have examined relationships among positional behavior and a variety of ecological variables, the capacity for primates to exhibit intraspecific positional behavior variation in …

Reimagining the Inner Ear: A Morphometric Modeling Approach for Establishing Shape Change in the Evolution of the Human Otolith System
… systems, particularly in the evolution of human positional behavior. The peripheral vestibular system of the inner ear comprises the organs responsible for this sense; the semicircular canals (detecting angular acceleration) and otolith organs (utricle and saccule; detecting linear acceleration, …

The Ape Ecological Niche: Posture and Hand Use in Gibbons and Macaques and the Influence of Manual Skill on Cognitive Development in Apes and Humans
… of primates were analyzed focusing on their positional behaviour and manual skill. Results support the hypothesis that gibbons exhibit a unique feeding style associated with their orthogrady/suspensory postures in comparison with pronograde macaques. This was demonstrated by their increased …
