چکیده
This study was conducted to survey the phenotypic plasticity in five populations ofMosul bleak (Alburnus mossulensis). Hence, a total number of 219 speciemens weresampled from Gamasiab, Karoon, Kashkan, Khersan and Sepidbarg rivers usingelectrofishing equipment. The left side of specimens were photograped using a digitalcamera with six megapixle resolation. Then, the outline curve was drawed usingTpsDig2 and resampled with 150 point in equal distances on 2D pictures. TPS datawas converted to a readable file for EPA analysis in EFAWIN software. EPA analysiswas carried out with choosing 17 shape harmonics (with two constants and fourcoefficients per harmonic) and removing non-shape data using EFAWIN software.Data were analysed by PCA and CVA/Manova analysis using Past software. Theresults showed a significant differences between populations, but Sepidbarg one interms of body shape (P< 0.05), dividing studied populations into three groups. Basedon differences in environmental charactrestics of populations habitats, the observedmorphological difference can be as result of their adaption to different environmentalconditions.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
