FIGURE 1  Map of the study site and location of the three study populations. Blue lines represent roads. (A) The region circled in red represents high disturbance habitat, the region circled in yellow represents low disturbance habitat, and the region circled in green represents minimally-disturbed natural habitat. (B) Area of the high disturbance habitat. Black rectangles represent garbage dumps. Green pushpins represent the location of reproductive burrows. (C) Area of the habitat with minimal disturbance (natural habitat). Pink pushpins represent the location of reproductive burrows. The white line in the figure is a makeshift road in the wetland and is generally abandoned by residents, and they prefer the road marked with a blue line. (D) Area of the low disturbance habitat. Blue pushpins represent the location of reproductive burrows.
FIGURE 2  Statistics on the intensity of different human activities within each habitat across the observation period (the number of automobiles, motorcycles, and stray dogs were periodically counted and then compared in t-test directly to illustrate the diversification of intensity). *p < 0.05, **p< 0.01.
FIGURE 3   Statistics on (A) number of burrows per breeding pair in the three habitats, (B) distance between adjacent reproductive burrows (IRBD), and (C) distance between all burrows (IABD) in the three habitat conditions. *p < 0.05, **p< 0.01.
FIGURE 4  Statistics on flight initiation distance of individuals (A) and home range size (B) of breeding pairs in three habitats. *p < 0.05, **p< 0.01.
FIGURE 5  Burrow site selection of breeding pairs in the three habitats. (A) The location and number of reproductive burrows by habitat. (B) The volume of mounds selected as reproductive burrow sites by habitat. (C) The distance of reproductive burrow to the nearest road by habitat. *p < 0.05, **p< 0.01.
FIGURE 6  The shape and size of mound selected as den site in different habitats. (A) natural mound in natural habitat. (B) natural mound in high disturbed habitat. (C) constructed mound in natural habitat. (D) constructed mound in high disturbed habitat. (E, F) hill in low disturbed habitat. The white arrows in the pictures illustrate the cage (80 cm in height) as the reference and the black arrow in figure B is the road next to a reproductive burrow (HDH 13: Supporting Information FIGURE S2).
