Abstract AR
درس التوزيع و التنوع للأحياء القاعية Meibenthos في رواسب جنوب بحر قزوين و حددت علاقتها بالعوامل البيئية.
جمعت عينات الرواسب فصليا من 12 محطة (تتراوح أعماقها ما بين 5 و 10 و 20 و 50 م) خلال عام 2012.
قيست درجة الحرارة و الملوحة و الأوكسجين الذائب و الأس الهيدروجيني أثناء جمع العينات و بجهاز CTD (التوصيلية، درجة الحرارة و العمق)، فضلا عن قياس حجم الدقائق و المادة العضوية الكلية و كربونات الكالسيوم.
تراوحت درجة حرارة الماء (9.

تم التعرف على 40 نوعا ينتمون إلى 29 جنسا من 25 عائلة من المجموعات الحيوانية الأربعة: Foraminifera و Crustacea و Worms و Mollusca، وقد شوهد Ammonia beccariicaspica من الأنواع الشائعة في جميع المحطات.
اعتبر العمق عاملا مهما في توزيعMeibenthos.
قيس الحد الأعلى و الأدنى لمؤشر شانون بعمق (5 و 50 متر)، فقد تراوح بين (0.

Abstract EN
Biodiversity and distribution of benthic Meiobenthos in the sediments of the Southern Caspian Sea were studied in order to introduce and determine their relationship with the environmental factors.
From 12 stations (ranging in depths from 5, 10, 20 and 50 meters), sediment samples were gathered for four seasons (2012).
Temperature, salinity, dissolved Oxygen and pH were measured during sampling with CTD (conductivity, temperature and Depth).
Percentage grain size and total organic matter and calcium carbonate were measured.
The average water temperature ranged from 9.
52 to 23.
93 ͦC, dissolved Oxygen from 7.

From the 4 groups of animals (Foraminifera, Crustacea, Worms and Mollusca), 40 species belonging to 29 genera of 25 families were identified Ammonia beccarii caspica, was the common species in all sampling stations.
Depth was an important factor in the distribution of meiobenthos.
Mean of maximum and minimum Shannon index were measured at depth of 5m and 50 m and were in the order of 0.
93 and 0.
43, respectively.
Account of Shannon and Peilou's index showed that this area is under pressure and is not steady.
