Coevolution of Cyanogenic Bamboos and Bamboo Lemurs on Madagascar
Fig 4
Lemur's degree of specialization towards bamboo plants traces on the phylogeny of lemurs, as inferred from a five gene fragments analysis.
Possible states were "generalist" (either obligate of facultative), "facultative specialist" meaning that bamboo is the major food plant but other plants are also regularly consumed in nature and "obligate specialist" meaning that bamboo is the sole food plant accounting for more than 95% of the lemur's diet.
