The Endangered Javan slow loris (Nycticebus javanicus), is a small nocturnal primate endemic to Java. A population was recently located in a severely human-dominated ‘talun’ habitat in West Java. For the first time, we followed wild javan slow lorises with radio-tracking. Facing the loss of habitat due to anthropogenic disturbance, information on behaviour and ecology can help to investigate how slow lorises are surviving and adapting in such a human-dominated area.
During this study, 5-minute instantaneous observation samples were used to record the behavior of 7 Javan slow lorises. Observations occurred between 1800 and 0000 over a 3 month period. We collected the lorises height in the tree, substrate size and type was recorded during the observations. Non-parametric Chi-square test used to explore behaviors and vertical substrate use (substrate height).
Substrate height use varied significantly during different activities (0-15 m). Lorises performed most of their activities in 1-5 m (53,51%) and least in < 1 m height (3,29%). Interestingly, even least used, inactive, travel, forage and alert behavior also recorded in this height (< 1 m). Our data showed that inactive, forage and alert occured mostly in bamboo, while travel mostly in bushes. Lorises also observed crossing on artificial substrate (wire) and the ground.
The result revealed the ability to utilize varied substrate height. Lorises in talun plantation use < 1 m height for inactive behavior despite of its vulnerability of potential predator presence. Nonetheless, this behavior only occured inside bamboo substrate which providing protection due to its high density. It reveals that they are adaptating to live in human-controlled habitats. Local awareness would provide a safer environment to these lorises in the long term.[/et_pb_text][/et_pb_column][et_pb_column type=”1_3″ _builder_version=”3.12.2″ parallax=”off” parallax_method=”on”][/et_pb_column][/et_pb_row][/et_pb_section][et_pb_section fb_built=”1″ admin_label=”Subscribe” _builder_version=”3.12.2″ background_color=”rgba(0,0,0,0.37)” use_background_color_gradient=”on” background_color_gradient_start=”#D883F8″ background_color_gradient_end=”#352DBE” background_color_gradient_direction=”96deg” background_color_gradient_start_position=”29%” background_image=”http://18.104.22.168/~sccs/public_html/wp-content/uploads/2018/09/5-1.jpg” background_blend=”overlay” custom_margin=”|||” custom_padding=”0||0||true|false” global_module=”309″ saved_tabs=”all”][/et_pb_section]]]>
