Abstract:
Objective To explore the geographic pattern of morphologic variation within snail populations across the mainland of China. Methods Twenty-one snail populations from the different regions were collected, and Shannon-Winer index and Euclidean distances within populations were used to analyze the spatial distribution of morphologic variation of Oncomelania hupensis. Results Longitude correlated significantly with Shannon-Winer index and Euclidean distances within populations, and the correlation coefficients were 0.719(P
