Figure 3 with 3 supplements
Estimates of associations between 17 terrestrial mammals across camera trapping stations with different human modifications in the Yarlung Zangbo Grand Canyon.
Associations are shown for the region’s (a) minimum (Lower), (b) mean (Moderate), and (c) maximum (Higher) human modifications.
Figure 3—figure supplement 1
95% confidence intervals of residual associations between species pairs at lower human modification level.
* denotes significant associations (i.e. p<0.01).
Figure 3—figure supplement 2
95% confidence intervals of residual associations between species pairs at moderate modification level.
* denotes significant associations (i.e. p<0.01).
Figure 3—figure supplement 3
95% confidence intervals of residual associations between species pairs at higher modification level.
* denotes significant associations (i.e. p<0.01).

Figure 5 with 1 supplement
Density distributions of encounter time between successive detections of species pairs (in log-transformed days) in low- and high-human modification (a) and human presence (b) habitats, and differences in time-to-encounter between species pairs in low- and high-human modification (c) and human presence (d) habitats.
The solid vertical lines in (c) and (d) represent mean differences, and the dashed vertical lines indicate 95% confidence intervals.
