| description | <p>This paper presents the findings of a study conducted on the Eastern Hoolock Gibbon <em>Hoolock leuconedys</em> in Mehao Wildlife Sanctuary and outside to the south of the park, Arunachal Pradesh, India investigating the daily path length (DPL) and home range used by the species in two forest areas with different disturbance gradients. The four habituated groups of <em>H. leuconedys</em> in fragmented and contiguous forest areas, two groups in each of the forest types, showed considerable variation in their DPL ranging from 6.59m to 1019.01m with a mean distance of 192.75m (SE = ±26.48) in 73 full day observations. Although the mean DPL was recorded with very little variation across the seasons in both the forest types, it was significantly different from fragmented forest. Similarly, the home range size also varied among the groups and was estimated as the maximum for Group D (24.62ha) followed by Group E (16.28ha) in contiguous forest and Group B (2.49ha) and Group A (1.09ha) in fragmented forest. Also, there was a distinct seasonal pattern of home range used by all the study groups with largest seasonal home range in monsoon and pre-monsoon season in fragmented and contiguous forest respectively. The DPL and home range of <em>H. leuconedys </em>in Arunachal Pradesh has been highly affected by forest fragmentation and/or canopy discontinuity which makes the species vulnerable to hunting, predation by feral dogs and hawks and ultimately local extinction. Thus, the findings of the present research evoke the question of long term survival of the species in fragmented forests.</p><div> </div> |
