Honess, P., Fernadez, L. 2011. Environmental enrichment for captive and wild-born macaques. Enrichment Record 9, 16-18.

Although the use of wild-born primates in research is banned in some countries, in others it is commonplace. It has been demonstrated that not only do wild-born primates react more strongly to some stressors than those that are captive-born, but they also use inanimate enrichment less. Given our understanding of the consequences of elevated stress for animal welfare, as well as the quality of science, more consideration should be given to the enrichment, and even the use, of wild-born macaques in biomedical research.
