Our results provide new evidence of the underexplored dietary ecology of
François’ langurs in the fragmented limestone habitat. By documenting
the foraging data from unique geographical populations using
instantaneous scanning sampling methods, we qualitatively assessed the
flexibility and adaptability of François’ langurs. The data revealed
that the François’ langurs’ diet has a high degree of flexibility with
seasonal variations, which could be advantageous for adapting to current
habitat changes. In addition, the François’ langurs’ diet showed a high
degree of selectivity, suggesting that their diet was highly dependent
on important species in the habitat.
