JNU Prof. Oh Hong-sik (Department of Biological Education in College of Education, Graduate School of Convergence Science and Technology Cooperation) and his team said, “In order to conduct research on the ecological interaction mechanism of wild animals throughout Jeju Island, the team installed and analyzed a camera trap (unmanned sensor cameras). As a result, the team found that the activity pattern of siberian roe deer shows a very high overlap with sika deer in time and space than other mammals (Jeju weasel, badger, wild boar, etc.) and verified that it shows statistically significant results.”

This study was published in <Mammalia (March 2023, first author Maniram Banjade, postdoctoral researcher)> of the internationally renowned journal on mammalian research (SCIE), on the title of 'Spatiotemporal overlap between Siberian roe deer (Capreolus pygargus tianschanicus) and sympatric mammalian species on Jeju Island'. , South Korea’

Roe deer and sika deer belong to the Artiodacyla family and the Cervidae family. Professor Oh’s team identified two subspecies of deer that inhabit Hallasan Mountain last year. In addition, by analyzing the maternal lineage structure, the correlation between the inflow route and the group was found and reported in an international journal.

Professor Oh Hong-sik said, “The results of this study show that the activity patterns of roe deer, which are endemic to Jeju, and sika deer, which are artificially introduced alien organisms, are very similar seasonally and spatially. Therefore, it suggests that competition among the species may occur in the habitat. sika deer have a larger body type and a wider range of activities than roe deer, so they are very likely to dominate the competition. Therefore, administrative and financial support should be made in order to continuously monitor activity patterns between the two species and prevent damage to native species by exotic organisms. It is necessary to understand the ecological interactions between wild animals of the same species and establish a system to evaluate and manage the ecosystem so as to preserve biodiversity.”
