Climatic and Altitudinal Influences on Variation in Macaca Limb Morphology
Figure 4
First and second PC factor scores of log-shape variables in males. The following labels designate individuals in each species. Assamese macaques: ▪, crab-eating macaques: ▴, Japanese macaques: ▾, rhesus macaques: ◆, pig-tailed macaques: grey ⚫, and Tibetan macaques: pink ⚫. The first PC axis contrasts limb lengths from joint diameters while the second PC axis juxtaposes the upper limb from the lower limb.
