“…Values of physical-chemical parameters showed variations in the current study among four sites over ten months. WT ranged from 14.200 °c in Al-Mansoury during January and 33.900 °c in Al-Sada during July, while ranging between 15.100-32.900°c in Al-Baraka and Al-Dawody respectively.WT recorded no Significant differences in all sites p >0.05. some species appeared in the hot months such as Nitzschia palea, and Oscillatoria princeps, and some species appeared in the cold months such as Gomphosphaeria semen-vitis, Dicloster acuatus because WT is important for the physiology, behavior, distribution, survival, growth, and reproduction processes 31,32 . The solubility of gases and salts in water is influenced by temperature, this is a confirmed negative correlation between WT and DO (r= -0.603) which is a significant component.…”

“…phytoplankton recorded during intermittent periods include Gomphosphaeria semen-vitis, Dicloster acuatus, Tetrastrum heteracanthum, and Dictyocha fibula have a strong positive correlation with NO3and PO4 because these nutrients limiting factors for the growth of phytoplankton. On the other hand, these species include a strong negative correlation with WT and EC, WT is important for the physiology, behavior, distribution, survival, growth, and reproduction processes 31,32 . The Shannon diversity indicator is widely used to determine diversity that considers both the number and evenness of species in a community.…”

Biodiversity is one of the important biological factors in determining water quality and maintaining the ecological balance. In this study, there are 223 species of phytoplankton were identified, and they are as follows: 88 species of Bacillariophyta and were at 44%,70 species of Chlorophyta and they were at 29 %, 39 species of Cyanophyta and they were at 16 %, 12 species of Euglenozoa and they were at 4 %, four species of Miozoa and they were at 3 %, and, Phylum Charophyta and Ochrophyta were only eight and two species, respectively and both of them were at 2%. The common phytoplankton recorded in the sites studied include Nitzschia palea, Scenedesmus quadricauda, Oscillatoria princeps, and Peridinium bipes, These species recorded a significant positive correlation with Ec, Sio3, and WT. Phytoplankton including Gomphosphaeria semen-Vitis, Dicloster acuatus, Tetrastrum heteracanthum, and Dictyocha fibula, recorded a significant positive correlation with NO3, PO4, DO, and PH. Water temperature ranged between 14.200 -33.900 ºc in Al-Mansoury and Al-Sada respectively. Electrical conductivity ranged between 2.790 -11.900 ms/cm in Al-Sada and Al-Mansoury respectively. PH ranged between7.750-8.600 in Al-Dawody and Al-Mansoury respectively. Dissolved Oxygen (DO) ranged between 5.950 -13.000 mg/l in Al-Dawody and Al-Mansoury respectively.WT recorded negative correlation with pH (r= -0.591), NO3 -2 (r= -0.463) and DO (r= -0.603). Nitrate ranged between 0.570-12.200 µg /l in Al-and Al-Sada respectively. Phosphate ranged between 0.003-0.154 µg/l, in Al-Dawody and Al-Mansoury respectively. Silicate ranged between 51.200-198.600 µg /l in Al-Baraka and Al-Dawody respectively. Shannon -Weiner index (H`) ranged between 2.275-3.162 in Al-Dawody and Al-Mansoury respectively. Simpson index ranged between 0.856-0.950 in Al-Mansoury and Al-Sada respectively, while the Evenness index was 0.514-0.933 in Al-Dawody and Al-Baraka respectively. Shannon-Weiner index (H`) recorded a significant positive correlation with the Simpson index .

“…In an aquatic environment where water flow is weak, floating algae dominate, with its species’ composition often determined by environmental factors ( Mashwani 2020 ). The microalgae present in the Jiri marshes were mainly composed of Bacillariophyta and Streptophyta ( Ali et al 2019 ; Garduño-Solórzano et al 2020 ). While it is known that Chlorophyta tends to dominate in other aquatic environments ( Amorim and Moura 2021 ), our results suggest that environmental differences determined the dominant microalgal groups.…”

The diversity indices of eukaryotic microalgal groups in the Jeonglyeongchi, Waegok, and Wangdeungjae marshes of Mount Jiri, Korea, were measured using Illumina MiSeq and culture-based analyses. Waegok marsh had the highest species richness, with a Chao1 value of 828.00, and the highest levels of species diversity, with Shannon and Simpson index values of 6.36 and 0.94, respectively, while Wangdeungjae marsh had the lowest values at 2.97 and 0.75, respectively. The predominant species in all communities were Phagocata sibirica (Jeonglyeongchi, 68.64%), Aedes albopictus (Waegok, 34.77%), Chaetonotus cf. (Waegok, 24.43%), Eimeria sp. (Wangdeungjae, 26.17%), and Eumonhystera cf. (Wangdeungjae, 22.27%). Relative abundances of the microalgal groups Bacillariophyta (diatoms) and Chlorophyta (green algae) in each marsh were respectively: Jeonglyeongchi 1.38% and 0.49%, Waegok 7.0% and 0.3%, and Wangdeungjae 10.41% and 4.72%. Illumina MiSeq analyses revealed 34 types of diatoms and 13 types of green algae. Only one diatom (Nitzschia dissipata) and five green algae (Neochloris sp., Chlamydomonas sp., Chlorococcum sp., Chlorella vulgaris, Scenedesmus sp.) were identified by a culture-based analysis. Thus, Illumina MiSeq analysis can be considered an efficient tool for analyzing microbial communities. Overall, our results described the environmental factors associated with geographically isolated mountain marshes and their respective microbial and microalgal communities.

“…The goal of the current study is to have advance knowledge of the distribution of algae in these aquatic habitats. More recently, a number of algal new record study was added to Iraqi algal flora [13][14][15][16][17][18][19] . Algae depend on a variety of environmental parameters, including temperature, pH, and others, to grow and reproduce…”

A study of non-diatom algal species composition in twelve sites from Greater Zab River path within Erbil Province, was carried out from April 2021 to January 2022 with monthly sample collection in twelve studied sites. Among them site 4,5,6,7 and 9 are the first for algal study in this area. The 112 different species of algae belong to 33 genera, 25 families, 13 orders and 4 divisions have been identified. The predominant genera included Spirogyra and Cosmarium 17, 8 taxa respectively. 13 taxa were new recorded to Iraqi Kurdistan algal flora and 9 of them were new recorded to Iraqi algal flora: Botryosphaerella sudetica, Muriella magna, Gloeotaenium loitlesbergianum, Apiocystis brauniana, Anabaena oscillarioides, C. distentum, C. tutum, C. contractum var. minutum, kirchneriella irregularis, Oedogonium suecicum f. australe, Coelastrum indicum, Oocystis lacustris, and Pediastrum braunii. Also, there were three new genera for Iraqi algal flora which including: Botryosphaerella, Muriella and Apiocystis. A brief description as well as the measurement is given for each species. Water temperatures ranged from 17.3 to 20.08 ºC, hydrogen ion concentration and electrical conductivity value ranged from 7.44 to 7.88 and 433.20 to 721.56 μS.cm-1 for all studied sites respectively. The aim of this study is to identify algal taxa in studied sites.
