The phytoplankton composition of five selected stations at the upper region of the Euphrates River, Iraq, was studied monthly during 1993. A total of 135 taxa were identified, and 43 species were common at all stations. Diatoms were the dominant group (65.2%), followed by green (12.5%) and blue-green algae (8.9%). More than 37% of the identified species belong to the three genera Nitzschia, Cymbella and Scenedesmus . Nine species were newly recorded for the Iraqi flora. The total cell numbers ranged between 0.25 × 10 6 − 45.82 × 10 6 cells/l. Highest cell numbers were found at the most northerly station. Cell counts were dominated by diatoms (77.1%) with two peaks during spring and autumn seasons. The seasonal variations of the dominant species were discussed. |
