English Abstract
The protozoa community of the water and sediment at Tigris river bank in Baghdad city was studied from January to October 2012.
A total of 180 samples have been collected at monthly interval of 9 samples from each of the water surface and soil at the east bank of river Tigris at three sites in Baghdad.
Some physical-chemical properties of water were determined, the ranges of these properties water temperature (T) from 10 to 30 C ͦ, hydrogen ion concentration (pH) from 7 to 7.9, electrical conductivity (EC) from 430 790 μs/cm, dissolved oxygen (DO) from 4.9 to 14 mg/L, nitrate (NO3 -1) from 1.085 to 8.9 mg/L and phosphate (PO4 -3) from 3 to 222.7 μg/L.
Among these factors temperature, NO3 -1 and PO4 -3 appeared to be the most effective factors on protozoan community.
During the study period total of 115 protozoan taxa were recorded from the water and sediment samples through microscopic examination for live specimens, most of these taxa were considered to be new records to Iraqi protozoan’s communities.
From the water 112 taxa were extracted, (63 of cilites, 25 of flagellates and 24 of sarcodines).While 22 taxa were extracted from the sediment, (12 of ciliates and 5 of each flagellates and sarcodines).
The mean population density in the water was 117216.7 ind/L-1, of these 1601140, 1083760 and 846750 ind /L-1 were counted from sites 1, 2 and 3 respectively.
The mean indices of diversity in the water were ranged from 8.948 at S2 during October and 0.268 at S1 during January.
The ciliata comprised the main group in the both habitat (water and sediment).
Dominant protozoan species of water were Aspidisca sp., Abstract----------------------------------------------------------------------------------------------------------------------- Cinetochilum sp., Coleps hirtus, Cyclidium sp.
of ciliata and Pseudochlamys patella of sarcodina.
Among the 22 protozoan taxa recorded from the sediment three protozoan taxa (Pleuronema marinum, Pleuronema setigera, Uronema marinum) were recorded from the sediment only, while the remaining 19 species were found in the both habitat (water and sediment).
