How Disturbed are the Disturbed Ones ? Impacts of Anthropogenic Stressors on the Socio-Ecological Interactions of Terai Gray Langur (Semnopithecus hector) in Shivalik Hills

Abstract

Animals respond to the changes in their habitats numerically and behaviourally. Alterations caused by anthropogenic stresses, like habitat degradation, fragmentation, urbanisation, changes in land use patterns, etc., changes the ecology of most species. Understanding the patterns adopted by these species to successfully survive and reproduce in such habitats is of utmost importance. This study tried to understand the impacts of human disturbance on the socio-ecology of Terai Gray langurs in Shivalik landscape, by comparing the ecology of langur troops inside the protected forest with the troops in disturbed forest. Four troops of Terai Gray langur, of comparable sizes, two in each treatment were selected.
