Abstract

تنتمي رتبة متفرعات القرون Cladocera إلى شعيبة القشريات Crustacea و صف غلصميات الأرجل Branchiopoda , حيث تشكل هذه الكائنات مع صف مجذافيات الأرجل Copepoda وشعبة الدواريات Rotifera معظم بلانكتون المياه العذبة، والتي تشكل بدورها حلقة رئيسية ووسطى في السلاسل الغذائية للأسماك.

أجرينا ولأول مرة دراسة تصنيفية لهذه الرتبة في المجرى السفلي لنهر الكبير الشمالي قرب مدينة اللاذقية ,والتي تعد مساهمة في تحديد التنوع الحيوي المائي السوري ، وقد تم تصنيف سبعة عشر نوعا تابعة إلى اثني عشر جنسا منتمية بدورها إلى خمس فصائل.

وتم تسجيل خمسة عشر نوعا منها لأول مرة في سوريا وهي :

The order of the Cladocera belongs to the Subphylum  of the Crustacea, class of the Branchiopoda  where these beings form with class of the copepoda,and phylum  of the rotifera most of the fresh water plankton, which in turn forms a basic and medium link in the fish  Food chains.

We have for the first time classified this order in the lower riverbed of the North Grand River near the city  of Lattakia, this study is considered a contribution to determining the Syrian biodiversity.Classification has been done on seventeen species related to the twelve genera which in turn belong to five families.

For the first time in Syria , fifteen species have been registered and they are:

 

A. guttata , A.rustica , chy.sphaericus , G.testudinaria, L.quadrangularis, P.aduncus, Di. Brachyurum , B.longispina , Ma.laticornis , I.spinifer , D.longispina, C.quadrangul , C.pulchella , C.rigudi , C.rotunda.
