Status, mechanism, suitable distribution areas and protection countermeasure of invasive species in the karst areas of Southwest China

Biological invasion is one of the major threats to global biodiversity attracting a primary focus scientific attention. During past decades, due diversity and peculiarity species, coupled with vulnerable ecosystem, karst areas have received more Numerous investigations studies confirmed that in Southwest China are suffering from biological invasions under intensified human activities climate change they caused. Despite some fundamental research on invasive species has been conducted understand distribution areas, mechanism response ecosystem still lack sufficient knowledge. In this paper, we summarized habitat characteristics status invasions. This paper comprehensively analyzed results development trends China, so as promote relevant areas. We found were increasing years. also revealed possible including competition, mutualism, allelopathy phenotypic plasticity by summarizing Moreover, was described aspects community, genetic levels, etc. By comparing area, common strong fecundity rapid growth rate, environmental adaptability, high existing simulated predicted species. Overall, three suitability covering Chinese southwest Karst which include southern Yunnan-Guizhou Plateau, foothill area Min-Yue-Gui Yunnan. It worth noting Sichuan Basin higher risk compared its surrounding mainly because Therefore, suggest general survey alien should be carried out soon possible, focusing suitable for early warning. addition, establish database strengthen monitoring evaluate impact key maintain stability cave fragile ecosystem.
