Area of Science:

  • Primate biology
  • Zoology
  • Comparative anatomy

Background:

  • Accurate primate body mass data is crucial for evolutionary and ecological studies.
  • Previous compilations have limitations affecting their reliability.
  • Understanding body mass variation is key to primate research.

Purpose of the Study:

  • To present comprehensive adult primate body mass data.
  • To address challenges in collecting and standardizing body mass measurements.
  • To analyze body mass variability across primate species.

Main Methods:

  • Literature review and incorporation of unpublished data for 230 primate species.
  • Discussion of methodological issues: defining adults, accounting for environmental and physiological factors, data pooling strategies, and significant figures.
  • Statistical analysis of body mass variability, including the coefficient of variation.

Main Results:

  • Compiled data for 230 out of 249 recognized primate species.
  • Identified a positive correlation between mean species body mass and its coefficient of variation.
  • Highlighted significant shortcomings in previously used primate body mass datasets.

Conclusions:

  • The presented dataset offers a more robust foundation for primate comparative studies.
  • Awareness of data collection and variability issues is essential for accurate scientific conclusions.
  • Future research should consider these factors for improved primate ecological and evolutionary insights.
