Ecological studies were carried out to explore the floristic composition of its community type and assess the factors that affect its invasion to the study area. Furthermore, proximate analysis, mineral composition, phytochemical screening and GC/MS analysis of secondary metabolites were studied to explore the nature of compounds present and evaluate its potential uses. Forty-seven weed species related to 21 families were recorded in C. benghalensis community type. Poaceae, Asteraceae and Brassicaceae were the most important families. Portulaca oleracea, Cyperus rotundus, Dactyloctenium aegyptium and Euphorbia heterophylla were the common associates. Therophytes were the most frequent life-form (78.7%). The chorological analysis showed the prevalence of paleotropical, cosmopolitan and Mediterranean taxa. A canonical correspondence analysis (CCA) indicated that pH, cations (calcium, potassium, sodium and magnesium), anions (bicarbonates, sulphates and chlorides), soil texture (sand, silt and clay) and organic matter were the most effective soil variables for the distribution of C. benghalensis and its associated species in the study area. The highest values of succulence and mean leaf surface area were recorded in mango orchards, while the highest shoot length and phytomass were registered in the habitats of crop fields. The results also indicated that this plant is a valuable source of nutritional, mineral and phytochemical compounds; hence it can be used as potential source of relatively low-cost, palatable forage for livestock and might be of a very important medicinal value and should be explored further to extract new drugs. It should not be included in the harmful weeds.","PeriodicalId":42145,"journal":{"name":"Catrina-The International Journal of Environmental Sciences","volume":"35 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89269108","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study is to investigate the effect of some eco-friendly materials like waste agriculture extracts in order to reduce uses of chemical fungicides and to maintain sustainable development. Three experiments were conducted in the Laboratory, Greenhouse and Field. Neem cake, orange peels and rice straw were used to obtain eco-friendlynaturalfungicides while Sumi-8 was used as a chemical fungicide and as a control. Three species from wheat cultivars, T.S.S, Morocco and Misr1 were used. Eco-friendlynaturalfungicides were applied as soak, foliar and applied together at the same time. Greenhouse and field experiments data showed that all natural extracts inhibited spore germination. Maximum inhibition reached to 100% by using neem cake and rice straw extracts followed with orange peels extract. In field experiments data showed that wheat yield was the highest using neem extract as soak + foliar application. The increase in wheat yield reached to 41.3% compared to Sumi-8 fungicide as healthy control. Also the results showed an increase in the percentage of carbohydrates, proteins, and wheat gluten, which is one of the main characteristics of the wheat quality. In conclusion these extracts can be used instead of chemical fungicide to cost effective, use safe and non-polluting environment.","PeriodicalId":42145,"journal":{"name":"Catrina-The International Journal of Environmental Sciences","volume":"31 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80843029","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both concentrations of chitosan nanoparticles caused deleterious effects on germination and seedling growth criteria. Germination was greatly reduced in both concentrations as compared to control (distilled water). The magnitude of decrease was much pronounced with the higher concentration of chitosan nanoparticles (0.1%). On the other hand, the lower concentration of CsNPs (0.05%) increased the content of total phenols and the activities of antioxidant enzymes (catalase, ascorbate peroxidase, peroxidase and polyphenol oxidase) as compared with those of the control seedlings. This might indicate that the relatively low concentration of chitosan nanoparticles enhanced the defense system of seeds by increasing total phenols and antioxidant enzyme activities.","PeriodicalId":42145,"journal":{"name":"Catrina-The International Journal of Environmental Sciences","volume":"21 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77545065","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The highest abundance of groupers were recorded in Ras Nasrani (76 SE±2.08) and Ras Um Sid (71 SE±2.0). There was no significant difference of groupers abundance between depths of 5 m and 15m in all of the studied sites. Based on their ecological behavior, groupers were divided into separate groups, and abundance was investigated for each group. Abundance of the cryptic and roving groupers was higher than that of the large mobile groupers, in all of the studied sites. While cryptic and roving grouper included both abundance and rare species, large mobile groupers species were all rare. The pattern of occurrence for the three different groups was repeated in all sites, except for Abu Galum MRPA where no large mobile grouper was recorded, probably due to over fishing. Diversity of groupers in all of the studied sites increased with the increase of abundance.","PeriodicalId":42145,"journal":{"name":"Catrina-The International Journal of Environmental Sciences","volume":"34 5 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77707755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The \"Kc\" and (Kn) factor was studied monthly and according to size classes, where females usually outnumbered males. The total average of Kc for sexes combined was 1.428 (SE.± 0.4134), this value is indication of a good condition. The value for both Kc and Kn increased in line with increased fish size until the size 31.4, and then decreased in value. On the other hand, both condition factors showed fluctuations among months, where the lowest value was recorded during August (within spawning season). The back calculation method was used to determine the age and growth for E. fasciatus. According to Bhattacharya method eight age group were verified growth parameters L∞=36.75 cm (TL), K= 0.35 year -1 and t0= -0.41121 were derived from Ford and Walford method.

Results of the main effect of the initial ramet size indicated positive effects of large ramet on obtaining better plug plant vegetative and rooting characteristics than medium or small size ramets. Results of the main effect of medium types showed that both M1 and M2 produced plug plants with better leaf petiole length, leaf fresh weight (FW) and Dry weight (DW) and crown diameter than M3, but root dry mass was not affected by medium types. Plug transplant grown on M3 had better contents of chlorophyll and carotenoids in their leaves than those on M1 or M2. Nutrient analysis of plug plant leaves indicated that plug plants grown on M1 had more P, K, Fe and Cu, and those on M2 had more N, Ca and Mn, while plug plants derived from M3 had more Mg and Zn. Results also indicated that plug transplants were not different in some vegetative and rooting characters among the different strawberry cultivars, especially in number of leaves per transplant, leaves FW and DW, crown DW and root DW, while root length was better in transplants of cv. 'Festival' than 'Tudla' and 'Sweet Charlie'. Leaves of plug plants in cv. 'Tudla' recorded higher chlorophyll and carotenoids than 'Festival' and 'Sweet Charlie' and also had more N, P, and K contents. Generally results indicated that optimum plug transplant production and growth was obtained by the culture of large size ramets in trays filled with any of the tested medium types and cultivars. These results indicated the possibility of producing large number of strawberry plug transplants in Egypt using soilless, suspended growing system as alternative to their production in field nursery to avoid the hazardous effects of soil fumigation and pesticide use.","PeriodicalId":42145,"journal":{"name":"Catrina-The International Journal of Environmental Sciences","volume":"32 1","pages":""},"PeriodicalIF":0.3,"publicationDate":"2019-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76334823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The influence of Sargassum sp., Corallina mediterranea, and Avicennia marina on RO membrane mineral scaling was evaluated using gypsum as a model scalant. Antibacterial properties for three marine extracts from Sargassum sp., C. mediterranea, and Avicennia marina were investigated with Gram-positive bacteria (ArthrobactersulfureusYACS14, Staphylococcus aureus) and Gram-negative bacteria (VibrioanguillarumMVM425, Escherichia coli). The antimicrobial results were detected for the two selected extracts as the most potent extracts (ethyl acetate, methanol crude extracts of the Avicennia marina leaves). Data showed that ratios of 3 and 5% recorded the highest suppression percentages (100%) for all tested bacteria including bacterial community collected from Eastern Harbor. On the other side, data confirmed that the anti-scalant properties by 100 ppm of Avicennia marina leave extract giving 85% of scale inhibition.
