Overview

Randomized trial characterizes dietary ecology in orangutans, suggesting limited influence of sex, age, or locality.

Key Points

  • The central aim is to characterize dietary ecology in extant Pongo to inform dietary reconstruction for fossils.
  • Analyzed dental microwear textures of 89 orangutans from the Selenka Collection dated to 1894
  • Investigated intrapopulation variation in dietary habits
  • Used climatic records to contextualize findings regarding resource availability.
  • No significant differences in dental microwear textures based on sex, age, or locality were found
  • Findings imply dietary resources consumed were consistent across the population
  • Study provides a valuable reference dataset for future paleodietary studies.
