This hypothesis has been tested in different forests of Madagascar. Leaf selection of all folivorous femus species was studied in relation to leaf chemistry. Except for two populations ofLepilemur subspecies all other folivorous lemur species (including two other subspecies ofLepilemur) select leaves with high concentrations of easily extractable protein or low concentrations of fiber, or both. This confirms the prominent role of these two components in leaf selection by folivorous lemurs. The average quality of mature leaves in a given forest, expressed as the ratio of protein to fiber concentrations, is positively correlated with the biomass of folivorous lemurs. This confirms the hypothesis tested and suggests rather uniform selection processes for arboreal folivorous primates across the world.
