主　　题：Alexandrium minutum MaxEnt,habitat suitability environmental variable potential distributions 

摘      要：Alexandrium minutum from the China Sea produces a range of toxins and causes damage to the local ecosystems and *** is essential to understand environmental factors affecting potential *** distributions of *** in the China Sea were predicted based on maximum entropy modeling,and dominant environmental variables were studied through analyses of variable contributions and response *** results showed that highly suitable areas were mainly located in the southwest of the Yellow Sea,the Laizhou Bay,and north of Haizhou *** coast of the South China Sea was predicted as a low-suitability area,and the coast of the East China Sea as an unsuitable *** temperature of the coldest month(T_min)had the largest drop in permutation importance but a low percent *** probability of presence of *** increased with increasing concentration of nitrate(NO3−)and annual mean temperature(T_ann)over a wide range of *** response curves decreased with increasing concentration of phosphate(PO43−)and ratio of NO_(3)^(−)to PO_(4)^(3−)(N_P_ratio)when PO_(4)^(3)−is above 0.049μmolL^(-1) and N_P_ratio above 4,indicating that low values of PO_(4)^(3−) concentration and N_P_ratio favour the occurrence of *** a predictor,the variance of annual temperature(T_Var)had the highest percent contribution and ***_(4)^(3−) was predicted to have much more information than the other variables,and exhibited the second largest drop in permutation importance and percent *** T_Var and PO_(4)^(3−) are the most important dominant predictor variables.
