Abstract

Primate behavior can be responsive to the different ecological pressures associated with different habitats, as well as to the effects of direct and indirect anthropogenic disturbance. The karst forest ecosystem of South Sulawesi (Indonesia) represents one of the few intact forests available for residual populations of the moor macaque, but our understanding of its habitat use is limited. In the present study, this gap in knowledge was addressed by observing the activity and habitat use of two groups of moor macaques and by assessing the suitability of different habitats in the karst forest. Through a fine-scale vegetation analysis of 1 ha of forest in Bantimurung Bulusaraung National Park, we identified the presence of two distinct habitats that differ in terms of forest structure and composition. The karst plain forest (KPF) provided a greater abundance and diversity of food resources than the karst tower forest (KTF). In addition, anthropogenic disturbance was high in the KPF but low in the KTF. Behavioral data collected via group scans indicate that the macaques devoted more time to feeding activities when in the KPF, suggesting an ability to adjust their feeding behavior to meet their nutritional needs. However, the larger of the two groups used the food-rich KPF more than expected, implying that the KTF may represent a valuable refuge for the smaller group, as it is a less risky portion of its home range. The results of this study therefore provide novel information on the ecology of moor macaques and their habitats that can inform conservation planning for remnant populations.
