[email protected] 23 24 Short title: Variation in food composition of bamboo lemurs 25 26 Abstract 27 Plants producing toxic plant secondary metabolites (PSM) deter feeding of folivores. Animals 28 that are able to cope with noxious PSMs have a niche with a competitive advantage over other 29 species. However, the ability to cope with toxic PSMs incurs costs for detoxification. In order 30 to assess possible compensations for the ingestion of toxic PSMs, we compare the chemical 31 quality of plants consumed by bamboo lemurs (genera Hapalemur and Prolemur; 32 strepsirrhine primates of Madagascar) in areas with and without bamboo.
