Abstract
Home ranges represent the space where individuals eat, mate and shelter. In calling anurans it generally incudes a territory with a calling site. There are two competing treefrog species on the Korean Peninsula, the endangered Suweon Treefrog (Dryophytes suweonensis) and the common Japanese treefrog (D. japonicus). These two species are known to have a significant impact on each other’s behaviour, and here we test for variations in home range and displacement distance. Data was collected through HDF tracking for 26 D. japonicus and 6 D. suweonensis, aiming at 72 h tracking per individual. We determined that despite the absence of variation in the two species’ home range, there was a significant variation in mean average displacement, with D. japonicus moving more than D. suweonensis. This result matches with our expectation as D. japonicus has been demonstrated to be bolder and more exploratory, and also uses a larger variety of microhabitats between two calling periods. These results are important in the larger framework of D. suweonensis conservation and the determination of the ecological space of these two species.
