Prevalence Study of Cyanophyta Algae in the Main Branch of the Tigres River and its Association with the Nation's Changing Climate
In the current study, 274 phytoplankton species belonging to 82 genera were identified from samples collected at five distinct sites along the Al-Gharaf River in the Thi-Qar Province of southern Iraq. Among these, Cyanophyta (blue-green algae) species outnumbered other non-diatom species by 20.07%. Sampling was monthly conducted over the course of a year, covering a stretch of approximately 59 kilometers. The abundance and distribution of phytoplankton were clearly influenced by both temperature and site-specific environmental conditions. Seasonal variations played a significant role: the highest abundance of algae was recorded at Site 4 during the summer, while the lowest densities were observed at Sites 1 and 3 during the winter. These findings highlight the impact of climatic and spatial factors on the frequency and density of blue-green algae, emphasizing the importance of considering seasonal dynamics in ecological assessments of freshwater systems.
