The American Journal of Primatology welcomes manuscripts on non-human primates in all areas of basic and applied life sciences. To meet the goals of the journal each manuscript must explicitly present and support the significance of its contribution to primatology. To this end it must be clear from the Abstract Introduction and Discussion of each manuscript that the principal focus is to increase significantly the understanding of the behavior or biology of primates in natural semi-natural or formal captive environments enhance welfare management or research value of primates in any or all of these environments advance knowledge of the evolution of primate diversity or contribute to the conservation of this diversity. The journal publishes both original Research Articles and Review Articles. In limited cases where the reported research is of scientific merit but compelling circumstances have limited the number of subjects available or constrained the scope of the data collected manuscripts may be considered for a Brief Report.
