Habitat Type and Group Identity Influence Activity Budgets in White-Handed Gibbons (Hylobates lar) in Two Habitat Types in Western Thailand.

ABSTRACT: Activity patterns reveal important information about how primates cope with challenging ecological conditions. This study investigates behavioral variation in white-handed gibbons (Hylobates lar) living at the ecological extreme of their range in a heterogeneous landscape in western Thailand. We spent 13 months studying 4 groups at Khao Nang Rum Wildlife Research Station in Huai Kha Khaeng Wildlife Sanctuary, where gibbons are found living in both evergreen and savannah habitats, both of which we describe as poor-quality habitat. Given specific phenological properties (e.g., predominance of deciduous species) of the savannah habitat, we predicted that food resources would be less available in the savannah habitat compared to the evergreen habitat, making the savannah an even lower quality
