Some effects of living conditions upon the pattern of growth in the stumptail macaque (Macaca arctoides).

Somatometric and weight measurements of stumptail macaques (Macaca arctoides) bred in various environmental conditions are presented. Environmental parameters may influence the pattern of growth in slowing down the 'growth rate' of monkeys bred in restricted laboratory environment as compared with monkeys bred in 'optimal' captive conditions: their subadult and adult linear dimensions are smaller.
