Plant secondary metabolites (PSMs) are compounds found in plant tissues designed to deter herbivores. Tannins, a type of PSM, can bind to proteins and reduce their availability to consumers. The detoxification limitation hypothesis suggests herbivores will prefer foods with lower amounts of PSMs and exhibit decreasing rates of feeding when PSM levels are high in order to stabilize the amount of PSMs ingested. Although this hypothesis has been supported by observations from other mammalian groups, it has not been tested in lemurs with regards to their consumption of tannins.
