Abstract
Invasive species have been introduced through increased global exchange and demand for rare flora and fauna, posing risks of disrupting ecosystems and reducing biodiversity. This study analyzes the habitat conditions of invasive species Lactuca scariola L. and Aster pilosus Willd using the RCP 4.5 and RCP 8.5 climate change scenario to predict their potential distribution. Using Nationwide Survey of Non-native Species in Korea from 2016 to 2021, occurrence data for both species were collected. Bioclimatic variables based on data from the Korea Meteorological Administration were generated according to the climate change scenario. Using these bioclimatic variables, altitude data, and occurrence data, MaxEnt models were built, and the results showed that all models had high explanatory power with AUC values above 0.8. Both species are likely to be distributed in low-altitude areas. Additionally, potential distributions indicated that both species would have a wider distribution across Korea under the RCP 8.5 scenario compared to the RCP 4.5 scenario. Lactuca scariola L. is expected to be primarily distributed in cultivated areas, including the Seoul metropolitan area, the west coast, and Gyeongsang Province in the 2030s and 2050s, while Aster pilosus Willd is expected to be mainly distributed in Gyeonggi Province, the Jeolla coastal area, and the southern coast.
