The role of leaf toughness on foraging efficiency in Angola black and white colobus monkeys (Colobus angolensis palliatus)

摘要

Objectives: Examining the relationships among foraging behavior, food mechanical properties, and masticatory morphology is a bourgeoning research topic among behavioral ecologists and functional morphologists. The purpose of this study was to assess the degree to which leaf toughness influences foraging efficiency with regard to ingestion rate, masticatory investment, and masticatory rate.
