In South Korea, Gekko japonicus has been observed persistently since the first report by Stejneger in 1907. Researches on the distribution, reproduction, and food items of G. japonicus have conducted, while studies on spatial ecological niche were not executed yet. We have investigated the home range and movement pattern of G. japonicus using radio-tracking method. This study was performed for 33 days from Jun 8 to July 10, 2018 near the cable car building, toilet building and woods in Geumgang Park (N 35°13′, E 129°04′), Dongnae-gu, Busan. The 17 geckos, 9 males and 8 females, were captured and, after attaching the transmitter package, the geckos were released at the collection sites. Gekko japonicus used trees and buildings as microhabitats at a ratio of 46.6% : 53.6%. The geckos moved significantly farther distance when they were on the trees (10.0±0.8 m) than when in the buildings (4.1±0.5 m). But it was not different between sex. For about one month, the average home range of G. japonicus was MCP: 644.8 m2, Kernel 50: 128.3 m2 and Kernel 95: 916.4 m2 and the size was not different between sex. During the research period, G. japonicus used about 27 × 27 m as core ecological area and used 64 × 64 m as a home range. Our results could be helpful to further understand the microhabitat use of G. japonicus and for its effective management.
