Use Remote Sensing Techniques to Study Epiphytic Algae on Phragmites australis in Um El-Naaj Lake, Mysan Province, Southern Iraq

Abstract

Abstract The aim of this study was to determine the quality and quantity composition of epiphytic algae of Phragmites australis in Um El-Naaj lake. Samples were collected from six Stations from November 2018 to October 2019. During this study, a remote sensing techniques was used to monitor the Community of epiphytic algae through storage and management data the geographic information system (GIS) program. The satellite images of the Landsat 8 satellite of the OLI which used to create visual images that facilitate the interpretation of the study area to identification and presence of these species and control their spread. The total number 306 species of epiphytic algae recorded during the study period were, belong to 61 genera. Seasonal variations in total number of species also noticed during the current study, Bacillariophyceae recorded 52.28%, with (160 species of 28 genera), Classes of Chlorophyceae and Cyanophycea recorded 12.67% (39 species of 20 genera 11) and 11.76% (36 species of 12 genera) respectively, while Classes of Fragilarphyceae recorded 14.37% ( 44species of 7genera), Coscinodisphyeceae recorded 13.59% (11 species, 7 genera). Then class of Euglenophyceae with 3.59%., Finally Chrysophyceae, Dinophyceae, and Rhodophyceae recorded 0.32% with 1 species of 1genera as they were present.
