Determination of suitable sex for morphological comparison in populations of Aphanius dispar using geometric morphometrics

摘要: Figure 1:(a) female and (b) male Aphanius dispar. Defined landmark points to extract the body shape data:(1) anterior-most point of the snout tip on the upper jaw,(2) dorsal edge of the head, perpendicular to the center of eye,(3) dorsal edge,(4) center,(5), ventral edge,(6) anterior-most and (7) posterior end of eye,(8) ventral edge of the head perpendicular to the center of eye,(9) anterior and (10) posterior ends of the dorsal fin base,(11) postero-dorsal end of the caudal peduncle at its connection to the caudal fin,(12) postero-ventral end of the caudal peduncle at its connection to the caudal fin,(13) posterior and (14) anterior ends of the anal fin base,(15) dorsal and (16) ventral origin of the pectoral fin, and (17) posterior end of the opercle.
