Population densities of Hylobates agilis in forests with different disturbance histories in Ulu Muda Forest Reserve, Malaysia.

ABSTRACT: Small ape habitat throughout Malaysia is rapidly being lost, degraded, and fragmented, and the effects of these changes on the abundance on this taxon are currently unknown. This study assessed the group density of Hylobates agilis in virgin forest, previously logged forest (1960s-1990s), and recently logged forest (2015-2017) of the Ulu Muda Forest Reserve (UMFR), Kedah, Malaysia. We conducted fixed-point active acoustic triangulation at nine survey areas to estimate group density. We used vegetation "speed plots" and satellite imagery to quantify habitat characteristics and used model selection to identify ecological predictors of group density variation. The estimated group density of H. agilis in UMFR was 4.03 ± 0.14 groups km^-2 , with an estimated total of 2927 ± 102 groups
