| Abstract |
Climate change is expected to exert a large impact on the spatial distribution of insects, yet limited analyses are available for assessing the influences of climate change on the distribution of Libellula angelina (Odonata: Libellulidae), which hindered the development of conservation strategies for this critically threatened dragonfly species. Here, a consensus model (BIOCLIM, GAM, MaxEnt and Random Forest) and niche analysis approach were applied to predict the dynamic change of potential distribution areas and ecological niche for L. angelina under future climate change. Meanwhile, the important environmental variables affecting the potential distribution of L. angelina were identified. The results demonstrated that the potential distribution pattern and ecological niche of L. angelina will not shift significantly in face of future climate change, but its highly suitable area in southern Beijing (China), the western and southern South Korea, and the southern Honshu Island (Japan) will decrease constantly. Further analyses indicated that the human influence index (23.8% of variation) is the highest factor in predicting the potential distribution of L. angelina, followed by the precipitation of warmest quarter (18.4% of variation). Based on the obtained results, we suggest that extensive cooperation among the countries (China, South Korea and Japan) be advocated to formulate the international conservation strategies, especially more attention and conservation efforts should be paid in those high-suitability areas of L. angelina to gain better protection efficiency, and proper artificial ecological restoration measures (e.g., creating suitable habitats, establishing additional natural wetlands, and raising citizens’ awareness) should also be exerted.
Implication for insect conservation: Our results indicate that there is no significant change in the location of the suitable habitat for L. angelina confronted with climate change, but the total area would constantly decrease due to human activities. Therefore, we should make more conservation efforts in those highly suitable areas, including Aosen and Hanshiqiao parks in China, Gangwon do and Doowoong parks in South Korea, and Chichibu Tama Kai and Ise-Shima parks in Japan, especially we should pay much attention to the anthropogenic impact such as human population and land use there. |
