Abstract
- Much of the primatology literature on stable isotope ratios of carbon (δC) and nitrogen (δN) has focused on African and New World species, with comparatively little research published on Asian primates. Here we present hair δC and δN isotope values for a sample of 33 long-tailed macaques from Singapore. We evaluate the suggestion by a previous researcher that forest degradation and biodiversity loss in Singapore have led to a decline in macaque trophic level. The results of our analysis indicated significant spatial variability in δC but not δN. The range of variation in δC was consistent with a diet based on C resources, with one group exhibiting low values consistent with a closed canopy environment. Relative to other macaque species from Europe and Asia, the macaques from Singapore exhibited a low mean δC value but mid-range mean δN value. Previous research suggesting a decline in macaque trophic level is not supported by the results of our study. [ABSTRACT FROM AUTHOR]
