چکیده مقاله :

چکیده زمینه و هدف: در این مطالعه خصوصیات ریخت‌شناسی دو جمعیت از ماهیان آفانیوس( Aphaniusdispar) در دو چشمه گوگردی اهرم و دالکی واقع در استان بوشهر با استفاده از ویژگی‌های ریخت‌شناسی موردبررسی و مقایسه قرار گرفت. روش بررسی: درمجموع 60 قطعه ماهی که شامل 30 قطعه در هر چشمه با تور مخروطی صید گردید. در نتایج ریخت سنجی ابتدا داده‌ها با استفاده از فرمول بکام استاندارد شدند، سپس از آزمون‌های تجزیه به مؤلفه‌های اصلی (PCA) و تحلیل تابع متمایزکننده (DFA) و آزمون کلاستر (CA) قرار گرفت. همچنین از آزمون Wilks´ Lambda به‌منظور مقایسه تفاوت‌های مشاهده‌شده در گروه‌های موردمطالعه استفاده شد. یافته‌ها: از بین 78 فاصله تراس آنالیز شده، 42 فاصله تفاوت معناداری را بین جمعیت های ماهی آفانیوس در رودخانه‌های اهرم و دالکی نشان دادند (P<0.05). جمعیت‌های موردمطالعه را می‌توان با اختلاف ریخت‌شناسی به خصوص در پیش مخرجی، ارتفاع بدن، فاصله باله سینه‌ای نسبت به باله شکمی، فاصله باله شکمی نسبت به باله مخرجی، طول ساقه دمی، طول سر، پیش شکمی، طول پشتی و پیش چشمی از هم متمایز کرد. بحث و نتیجه‌گیری: احتمالاً تفاوت‌های مورفولوژیکی این دو جمعیت نشان‌دهنده دو ذخیره مجزا در این دو چشمه است.

چکیده انگلیسی:

Abstract Background and Objective: I this study, morphological characteristics of two populations of Aphanius dispar from two sulfur springs of Ahram and Dalaki in Bushehr were compared investigated. Method: Totally sixty specimens, 30 from each spring, were caught by cone net. The morphological results were first standardized by Beckham equation and then investigated by principal component analysis (PCA), discriminant function analysis (DFA) and clustering analysis (CA). Wilks' Lambda test was used to compare the differences observed in the studied groups. Findings: Among the 78 truss intervals analyzed, 42 intervals showed a significant in the populations of A.dispar in Ahram and Dalki rivers (P<0.05). The studied populations are distinguished especially by pre anal, body height, distance from pectoral fin to ventral fin, distance from pectoral fin to anal fin, caudal peduncle length, head length, pre orbital, pre ventral and dorsal length. Discussion and Conclusion: Apparently, the morphological differences between the two populations signifies distinct stocks in the studied rivers.
