The study was conducted to compare the distribution and composition of the Molluscs community in 4 ecosystems (4 sites) in southern of Iraq, namely: (Site 1)- in Euphrates River at Al-Madinah city, (Site 2)- in Shatt Al-Arab at Al-Sharsh area, (Site 3)- in the Garmat Ali River at Al-Mashib area and Site 4- in the Al-seba area. Samples were collected from study sites during a period of January to August 2019. (11) species from the class Gastropoda and (4) species from the class Bivalves, species were predominated in most of the study months which are species: Melenodies nodosa, Bellamya bengalensis and Melanopsis turbculata from Gastropoda and two of the species are bivalve: Corbicula fluminalis and Limnoperna fortunei (Dunker, 1857), and the last species, L. fortunei, was recorded in the current study for the first time in freshwater of Iraq. The total biodiversity values of Molluscs at the Euphrates River at Al-Madinah area (Site. 1), Al-Sharsh area (Site 2), Al-Mashib area (Site 3) and Al-seba area (Site 4) were 3.1, 2.9, 2.4, 1.8, respectively, and It was noted that the highest seasonal densities of the species in the current study were recorded in the winter season, reaching 1013, 905, 762 and 639 individuals / m2 in four sites, respectively.
Shatt Al-Arab River is an important inlands river in Iraq, It is considered an important source of fresh and water for the city of Basrah, as it is used for drinking and orchards irrigation also used for industrial and commercial purposes. Sampling was carried out monthly from November 2019 to December 2020 from Shatt Al-Arab River. The present study made records nine of algae species for the first time in Iraq. Represented by six species of Chlorophyta (Eremosphaera tanganyikae, Microspora wittrockii, Monoraphidium komarkova, Mychonastes pusshpae, Scenedesmus similagineus and Spongiococcum tetrasporum), one species of Cyanophyta (Pseudanabaena catenata), one species of Dinophyta (Impagidinium paradoxum), and one species of Euglenophyta (Strombomonas verrucosa).
The present study was made to observe the effect of phenolic extract isolated from the green alga Chara vulgaris on the larval stage (Cysticercus) of Taenia taeniaeformis in mice infected in the laboratory compared with two sets of control and Albendazole drug. It found The phenolic extract, after 3 days of treatment has more effect on the larval stage of T.taeniaeformis from Albendazole drug.The lowest average number of live larvae was 3.75 larvae at concentrations of 0.065 and 0.115 mg/kg of the phenolic extract and the highest average was5 larvae at the concentrations of 0.015 and 0.2 mg/kg of phenolic extract and Albendazole, respectively, while the lowest average number of dead larvae reached 2.5 larva by the same two concentrations.The highest average reached 6 larvae at the concentration of 0.115 mg/kg of phenolic extract, while the lowest percentage of dead larvae was 33.33% at the concentration of 0.015 and 0.2 mg/kg of phenolic extract and Albendazole, respectively.The highest percentage (61.53%) at the concentration of 0.115 mg/kg of the phenolic extract.The higher therapeutic efficiency was (63.96%) at the concentrations 0.065 and 0.115 mg/kg of the phenolicextract and the lowest the rapeutic efficiency (51.59%) was at the concentration of 0.015 and 0.2 mg/kg of the phenol and Albendazole, respectively.
The specific concentration of radioisotopes of Potassium 40K; Cesium 137Cs and Radium (224Ra ,226Ra, 228Ra) have been identified for soil, sediment, fish samples (Liza abu, Liza klunzingeri, Brachirus orientalius, Tylosurus crocodilus, Cyprinus carpio and Acanthopagrus arabicus) and kladophora as well as snails in the stations: Qurmat Ali; Al sadir Teaching Hospital; Umm Qasr Port and and Arabian Gulf 1 in 2016. The present study aims to detect the impact of both Chernobyl reactor explosion, Fokushima reactor destruction and the oil industries in the study region environments. The results of the soil and sediment analysis showed that there is an impact of Chernobyl accident. There are observed concentrations for the 137Cs; in addition to the effect of the oil industries in the soil, sediments, and Acanthopagrus arabicus fish and Kladophora crusbate plant. This was proved by measuring the concentrations of Radium isotopes in the amounts above the allowable rates globally and locally. The results of the current study showed that the rates of Potassium 40 were the most prominent in fish samples and the Kladophora crusbate plant, which represents the predominant radiation activity and it is within the permitted natural range. The results of this study can be considered as a basis for monitoring of the future changes.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
