Potential Suitable Area of Invasive Species Cryptomonas sp. under Climate Change Scenarios in China Sea Areas

Alien invasive algae along with ship ballast water have posed a serious threat to China’s marine ecological security. A clear understanding of the geographical distribution species and their response climate change can provide scientifi c basis for prevention control. In this study, combined environmental variables data, MaxEnt was used predict potential trend Cryptomonas sp. in four major sea areas China current, 2040s (2031-2050) 2090s (2081-2100), reveal dominant factors affecting distribution, analyze migration trends centroids highly suitable area, clarify key control areas. Results showed that: 1) The most important variable Temperature. Range (bio24). 2) Under current condition, suitability index whole area Yellow Sea, northern East corresponding Jiaxing, Ningbo, Dongying, Weifang Zhangzhou, special attention should be paid sp.. 3) scenarios total an increasing trend. 4) 2090s, centroid would generally move southeast or southwest. Bohai Sea moving different latitudes directions under scenarios. north. These indicated that may adapt by changingtheir
