Abstract AR
تمت دراسة الحيوانات القاعية الموجودة في خور اكبان في الفترة ما بين كانون ثاني و حزيران 2007.
و تم كذلك دراسة تراكيز المعادن الثقيلة و تشمل الرصاص و الحديد و الزنك و النحاس و الكروميوم.
و توضح التحاليل الكيميائية أن المحطة رقم 2 فيها أعلى النسب من المعادن باستثناء الحديد و الزنك حيث كان أعلى ما يمكن في المحطة رقم 1.
و قد تم جمع 1135 حيوانا في تلك الفترة تنتمي إلى 19 نوعا من الحيوانات القاعية في أربع مجموعات و هي الرخويات و تشمل 92.51 %.
بينما تشمل الحشرات و القشريات و عديدة الأشواك 1.94 % و 2.29 % و 3.26 % على الترتيب.
اختلف مقياس التنوع بين المحطات و كان أعلاها في المحطة رقم 1.
و تبين من مؤشر سورسن أن التشابه في الأنواع بين المحطات كبير.
Abstract EN
The macrobenthic fauna in bottom sediments of Ekpan Creek was studied from January to June 2007.
Analyzed heavy metals were Lead, Iron, Zinc, Copper, and Chromium.
Variations in chemical parameters showed that station 2 had the highest values recorded in all parameters except for Iron and Zinc, where they were higher at station 1.
A total of 1135 individual organisms were recorded.
Nineteen (19) macroinvertebrate taxa belonging to four major groups were identified.
Mollusca were the most dominant and constituted 92.51% density occurrence, while insecta, crustacean, and polychaeta constituted 1.94, 2.29, and 3.26% respectively.
Diversity varied at the study stations, with the highest taxa richness recorded at station 1.
Mollusca were positively significantly correlated with lead (P < 0.05, r = 0.836), and Zinc (P < 0.05, r = 0.96).
Sorenson index indicates similarity in species composition between the stations.
