Previous studies of Trachypithecus species indicated that they were selective feeders that
concentrated on relatively few food species/items. From January to December 2005, I …

Primate home range size and habitat use are affected by resource availability, which may
change seasonally. Limestone langurs (Trachypithecus genus), including the Critically …

Comparative studies of the diet of the same species in different habitats, and over the long
term, are essential to understanding a species' behavioral and ecological plasticity …

The six limestone langur taxa of Southeast Asia inhabit the rugged limestone karst
mountains, although the reason for their current restriction to this habitat is unclear. From …
