چکیده

قورباغه مردابی ridibundus sensulato  Pelophylax در خانواده  Ranidae قرار دارد. در این مطالعه 56 نمونه از جمعیت های مناطق دیشموک، دهدشت و لیکک در تابستان و بهار 99-98 جمع آوری و مورد مطالعه ریخت شناسی و ریخت سنجی قرار گرفتند. در نمونه های جمع آوری شده هفت ریخت مختلف از این گونه شناسایی گردید. بیش ترین فراوانی متعلق به ریخت یک بود. بر اساس تحلیل های انجام شده، میانگین تمامی 15 صفت ریخت سنجی بررسی شده در نمونه های دیشموک بیش تر از مناطق دیگر ثبت شد. نتایج آزمون t-test نشان داد که دو ریختی جنسی در جمعیت های مورد مطالعه وجود دارد. براساس آزمون آنالیز واریانس تفاوت بین گروه ها در هر دو جنس نر و ماده معنی دار بود و جدایی بین جمعیت نرها در تمامی صفات به جز قطر افقی چشم و در ماده ها نیز در همه صفات مشاهده شد. هم چنین نتایج  تحلیل های آماری نشان داد که دیشموک تا حدودی از دو منطقه دیگر متفاوت بوده که می تواند به شرایط جغرافیایی متفاوت و ارتفاع بالاتر این منطقه مرتبط باشد. هر دو تابع در تحلیل ممیزی معنی دار بودند. در مجموع در نرها 84 درصد و درماده ها 87/1 درصد از نمونه ها به طور صحیح در گروه خود قرار گرفتند.

چکیده [English]

Pelophylax ridibundus sensulato belongs to the family Ranidae. 56 specimens from Dishmook, Likak and Dehdasht areas were collected in spring and summer (2019-2020). Seven different morphs of this species were identified. The highest frequency was related to morph one. َAccording to the analysis, the mean values and standard deviations of all morphometric characters of Dishmook' samples are higher  than the other two regions. Respect to t-test, sexual dimorphism was observed. Analysis of variance showed significant differences between the studied groups in both male and female frogs. Separation between male populations in all traits (except horizontal diameter of eye) was observed. Separation between female populations in all characters was also observed. Based on discriminant analysis, both functions were significant. Statistical results showed that frogs of Dishmook are somewhat different from the other two regions that can be related to different geographical conditions and higher altitude. Overall 84% of males and 87.1% of females were placed in their expected groups.
