In Dornogobi, ID3 used the area alongside a railroad from 
October 2002 to April 2003, then moved south-westward 
approximately 140 km in liner distance and stayed around there 
until July 2003 (Figure 4). ID3 went back to the area where it 
had been captured by September 2003. ID4 moved northwest 
approximately 80 km in liner distance along the railroad in late 
November 2002 and stayed there until mid-April. Then ID4 
went south-eastward approximately 100 km in liner distance 
and stayed there after that. The cumulative distances moved 
over a year were 1112 km and 1011 km and the maximum 
distances moved during one week were 80 km in late March and 
79 km in late November for ID3 and ID4, respectively. The 
gazelles used the eastern areas along the railroad in winter and 
the southern and south-westward areas in summer in their 
annual range (Figure 5).

3.2 Seasonal patterns of NDVI in the summer and winter 
ranges 
NDVI values in each range demonstrated seasonal change, with 
highest values between June and September and the lowest 
values between December and February in Omnogobi (Figure 
6) and Dornogobi (Figure 7). During winter, NDVI of all ranges 
except winter range of ID4 decreased to nearly or below 0. 
In Omnogobi, NDVI of the summer range was higher in 
summer, while it was lower than that of overall average from 
October to November (Figure 8). In contrast, NDVI of the 
winter ranges was lower than that of overall average almost 
throughout the year. However, it was higher from October to 
December (Figure 8). 
In Dornogobi, NDVI of the winter ranges was higher than that 
of the summer ranges and overall average almost throughout the 
year (Figure 9). Seasonal changes of relative NDVI of the 
summer ranges were slight, however, NDVI values were higher 
in summer and lower in winter than overall average (Figure 9).
