Relationship between allotopic and syntopic vertical positions of all Notropis and Cyprinella congeners. Syntopic data were scaled down to fit the number of observations accumulated in allotopic trials. Gray bars represent allotopic trends while hollow bars represent syntopic trends. P values of all allotopic and syntopic trials are displayed in Tables 1 and 2. 50
