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).
