چکیده
چکیده. هدف از مطالعه حاضر بررسی تغییرات شکلی ناحیه سر در جمعیت‌های دامنه شمالی و دامنه جنوبی گونه Clinopodes flavidus در ارتفاعات البرز با استفاده از روش ریخت‌سنجی هندسی بر پایه لندمارک بوده است. به این منظور تعداد 17 لندمارک و شبه لندمارک روی ککسواسترنیت چنگال‌های سمی و هفت لندمارک و شبه لندمارک روی تارسانگولوم چنگال‌های سمی با استفاده از نرم افزار TpsDig2 قرار داده شد. داده‌های حاصل از لندمارک پس از تحلیل پروکراست با شیوه‌های آماری چند‌متغیره شامل تحلیل تجزیه مؤلفه‌های اصلی (PCA) و تحلیل متغیرهای کانونی (CVA) با استفاده از نرم افزارهای PAST و MorphoJ مورد بررسی و مقایسه قرار گرفتند. نتایج نشان داد که تفاوت معناداری بین شکل ککسواسترنیت چنگال‌های سمی میان جمعیت‌های این گونه در منطقه البرز وجود دارد (p<0.001). این مطالعه قابلیت استفاده از روش ریخت‌سنجی هندسی بر پایه لندمارک را برای تمایز جمعیت‌های مختلف Clinopodes flavidus در منطقه البرز نشان می­ دهد.

چکیده English

The aim of this study was to determine the variations among cephalic plates of individuals in two populations of Clinopodes flavidus in Alborz Mountains, by means of landmark-based techniques of geometric morphometrics. Therefore, 17 landmarks and semi-landmarks on the coxosternite of poison claw and seven landmarks and semi-landmarks on the tarsangulum of poison claw were selected using TpsDig2 software. Data of landmarks, after procrust analysis, were subjected to various multivariate analyses, such as Principle Component Analysis (PCA) and Canonical Variate Analysis (CVA) by means of PAST and MorphoJ softwares. The results obtained demonstrated that shape variations in coxosternite were significantly different among various populations (p<0.001). This study revealed the usefulness of landmark-based geometric morphometrics in the differentiation of various populations of Clinopodes flavidus in Alborz Mountains.
