چکیده
Algae are one the primary producers in food web on the earth. Algae have many applications in assessment and evaluation of water quality in rivers and any other aquatic ecosystems. Among the algae, diatoms have a very important role in river water quality assessment because they response to any physical, chemical and biological changes in those aquatic ecosystems. This study was focused on the diatom flora of the Mordagh river and the effects of the ecological and climatic factors on biodiversity and frequency. In order to study, the samples were collected in ۴ sites during four different seasons in ۲۰۱۹-۲۰۲۰.Samples were treated with hot H۲O۲ (۳۵%) and HCl (۳۵%) to remove the organic materials and clean up the frustules of the diatoms. In this study, physicochemical factors such as PH, DO, EC were measured. Diatoms were identified using light microscope. The results showed that the most dominant taxa in the river were Nitzschia amphibia, Diatom vulgaris, Gomphonema sp. Furthermore, the results showed that Nitzschia amphibia had high dispersal in spring due to high precipitation whilst Diatoma vulgaris had high dispersal in autumn due to low flow in the river. This study is very substantial and important in diatom flora of Iran.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.
