چکیده

به منظور مقایسه ریخت‌سنجی جمعیت‌های تیله‌خوس(Capoeta capoeta) ، 713  قطعه ماهی از ۳۲ رودخانه حوضه خزر، ارومیه و هریرود مورد بررسی قرار گرفت. نمونه­ها پس از صید، توسط محلول گل میخک ۱٪ بیهوش و در فرمالین ۱۰% تثبیت و به آزمایشگاه انتقال یافتند. تصایر دیجیتال با استفاده از دوربین هشت مگاپیکسلی با شرایط یکسان تهیه و با استفاده از نرم‌‌افزار Tpsdig2لندمارک گذاری شدند. روی همگذاری لندمارک‌ها با استفاده از تحلیل پروکراست و حذف تغییرات غیرشکل با نرم‌افزار TpsRelwانجام شد. نتایج تحلیل متغیرهای کانونی نشان داد که تفاوت معنی‌داری بین جمعیت‌های سه حوضه وجود دارد و جمعیت هریرود کاملاً از جمعیت ارومیه تفکیک شد. جمعیت خزر با هر دو جمعیت همپوشانی نشان داد. تحلیل خوشه‌ای جمعیت‌ها با ضریب کوپرنیک 818/0، جمعیت‌های مورد مطالعه را به دو گروه اصلی تقسیم کرد، خزر و هریرود در یک گروه و ارومیه در یک گروه مجزا که نشان دهنده شباهت بیشتر حوضه خزر و هریرود به همدیگر است. فاصله جغرافیایی و تفاوت‌های زیستگاهی می‌تواند علت این امر باشد، با این وجود برای نتیجه‌گیری دقیق‌تر نیاز به مطالعات مولکولی می‌باشد.

چکیده [English]

In order to compare the geometric morphometrics of teilehkhus (Capoeta capoeta) populations, 713 specimens from 32 rivers in Caspian Sea, Urmia and Harirud basins were examined. Specimens were anesthetized in 1% clove oil solution after catching by a seine net and fixed in 10% formalin and transfered to laboratory for further studies. The specimens were photographed in a sililar condition by a Cannon 8MP and land marked in Tpsdig2 software. Superimposition of the landmarks was performed by Procrustes analysis to eliminate non-shape variations in TpsRelw. The Canonical Variate Ana;ysis (CVA) results of geometric morphometry showed significant differences among the populations and Harirud population was fully separated from Urmia populations. Caspia Sea population overlapped the both other populations. The Cluster Analysis (CA) grouped Harirud and Caspian Sea populations as a separate group from Urmia population, indication a more similarity between the Harirud and Caspian Sea populations. However, for more details, molecular studies are needed.
