Khansaa S. Farman | Emaduldeen A. Almukhtar
Abstract: Geometric morphometric techniques are widely used in systematic biology and represented as direct quantification and analysis of variation in biological shape and size, in present investigation were analyzed the variation in shell size and shape of Physa acuta in lotic and lentic ecosystem in Diyala River Basin, results indicated a significant differences in size of shell but no significance appeared in shell shape and the centriod size of the individual in lotic system larger than lentic system with absolute difference between them up to 6.96.
Keywords: Geometric Morphometric, landmarks, lotic, lentic, Physa acuta
