Total eight forest species were planted on coal mine overburdens aged 2, 3 and 5 years located in nearby areas of Korba, India. Sissoo (Dalbergia sissoo), Peltaphorum (Peltaphorum ferrugineum) and Bamboo (Dendrocalamus strictus) were best in harboring highest number of AMF. The mean root colonization in tree species was increased 61.98% in 3 years and 110.23% in 5 years compared with the species of 2 year. The dominant AMF were Acaulospora scrobiculata and Rhizophagus irregularis in 2 year overburdens and Funneliformis mosseae, Gigaspora and Sclerocystis in older overburdens and forest soil. The diversity index of AMF was found 1.80, 2.14 and 2.49 in 2, 3 and 5 year overburdens respectively while the diversity index of other soil fungi was found 1.61 in 2 years, 1.73 in 3 year and 2.10 in 5 year aged of overburdens compared to natural forest (2.21). Total 11, 25 and 29 ground species were recorded from 2, 3, 5 year overburden respectively and 25 species from the site of natural forest. The root colonization in ground vegetation was found 28.03%, 31.86% and 39.43% in 2, 3 and 5 year old re-vegetated overburden respectively in comparison to natural forest (29.08%). The status of soil pH and phosphorus was also ameliorated in older dumps.","PeriodicalId":14383,"journal":{"name":"International Journal of Scientific Research in Environmental Sciences","volume":"109 1","pages":"289-300"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84143960","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}

Batch mode experiments were carried out to study the effects of shaking speed, contact time, adsorbent dosage, and pH. Furthermore, equilibrium adsorption isotherms and kinetics were investigated. In the optimum operation condition, about 96.9 and 95.5 removal percentage of colour was obtained at 200 rpm shaking speed, 6 hr contact time and 0.2 g AC dosage. The experimental data were analyzed by the Langmuir, and Freundlich models of adsorption. The adsorption isotherm data were fitted well to Langmuir isotherm. The kinetic data has been analyzed using a pseudo-first-order, pseudo-second-order equation and intraparticle diffusion equation. The experimental data fitted very well the pseudo-second-order kinetic model with R 2 > 0.99. Consequently, the adsorption of MB onto the AC driven from sugarcane bagasse has a great potential to be used textile waste water treatment.","PeriodicalId":14383,"journal":{"name":"International Journal of Scientific Research in Environmental Sciences","volume":"78 1","pages":"301-307"},"PeriodicalIF":0.0,"publicationDate":"2014-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76864141","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 formol-ether concentration method was used to examine the samples. Data revealed an overall parasitaemia of 18 (18.0%). The size classes 301-400mm, 201-300mm and >169-200mm had 5(55.6%), 12(15.2%) and 1(11.1%) respectively while the size class 0.05), however the females had 11(20.4%) and the males had 7(15.2%) of their respective populations. Site specific endoparasitaemia showed that the gastro-intestinal tract harboured the highest (38.9%) parasitic load, while the kidney had the lowest (5.6%). The heart had (33.3%) and the blood and liver had (11.1%) parasitic load each. Fourteen (14) parasite species from 5 phyla were recovered from the fish samples namely: Protozoa - Coccidia sp. and Thelohanellus piriformis; Platyhelminth - Ascocotyle ceolostoma, Sanguinicola inermis, Sanguinicola armata, Atalostropion sp., Silurotaenia siluri, Tetrochetus coryphaenae, Biacetabulum appendiculatum and Tetraonchus monenteron; Nematoda - Strongyloides sp.; Acanthocephala - Acanthocephalus lucii and Neoechinorhynchus rutili; and Crustacea - Alebion elegans. Endoparasitaemia in the sampled population was influenced by the physico-chemical properties of the water body which is greatly affected by the intrusion of salt into the river due to its tidal conditions. However, the relatively high endoparasitaemia in the gastro-intestinal tract was associated with the nutrient rich ambience of the intestine which may allow easy establishment and multiplication of parasites.","PeriodicalId":14383,"journal":{"name":"International Journal of Scientific Research in Environmental Sciences","volume":"35 2 1","pages":"250-260"},"PeriodicalIF":0.0,"publicationDate":"2014-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89627949","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}

Blood samples were obtained from 180 apparently healthy cattle from three abattoirs (Bodija, Akinyele and Olorunsogo), using standard field and laboratory techniques. An overall parasitemia of 6.67% accounting for 12 positive cattle out of 180 cattle examined was recorded. Abattoir-specific prevalence indicated 3.33%, 2.22% and 1.11% for Bodija, Akinyele and Olorunsogo abattoirs respectively. The three species of parasites identified showed prevalences of 3.81%, 2.22% and 0.56% for Trypanosoma brucei, Babesia bigemina and Theileria parva respectively.

This study is an attempt to assess the sub lethal effects of dimethoate, an organophosphate insecticide on gill morphology, ventilation rate, oxygen consumption and electrolyte levels of common carp (C. carpio). Healthy juvenile fishes were exposed to a sub lethal concentration of 0.96 mg/l (60% of 96 h LC50) of dimethoate; and at 24, 48 and 96 h exposure blood and gill tissues were collected, oxygen consumption and ventilation rate was determined. The changes in the gills of exposed fish were characterized by epithelial hyperplasia, lifting and degeneration of respiratory epithelium, lamellar bending and curling, fusion and disintegration of secondary gill lamellae. The degree of damage showed direct correlation with the duration of exposure. The electrolyte levels also fluctuated, levels of calcium decreased and phosphate levels increased during the exposure. Oxygen consumption and ventilation rate showed significant decrease at all exposure durations. The study demonstrates high sensitivity of fish gills to dimethoate, at short term and sub lethal exposure.","PeriodicalId":14383,"journal":{"name":"International Journal of Scientific Research in Environmental Sciences","volume":"24 1","pages":"192-198"},"PeriodicalIF":0.0,"publicationDate":"2014-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86924998","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 experiments were laid out using RCBD with three replications. The results from combined analysis of variance in both normal and stress conditions indicated that there were significant differences among genotypes with regard to all studied traits which were due to high variation among the genotypes. It was found that the activity of enzymes including SOD, GPX and CAT were increased under drought stress conditions, so that tolerant genotypes had more changes in enzyme activity. On the other hand, MDA, Dityrosine and 8-oHdg were increased under stress conditions where sensitive genotypes had stronger enzyme activity. Calculations of the correlation coefficients among the studied traits under both stress and normal conditions also indicated that there were negative and significant differences between antioxidant activity, lipid, protein, and DNA decadence. Finally, with regard to all traits, it was revealed that in normal conditions genotypes 18 and 19 were the best performing lines, whereas the genotype 14 was least adapted line. Therefore, genotypes 18 and 19 showed higher levels of resistance to water stress and the genotype 15 was more sensitive to the drought conditions. The results also indicated that selecting more tolerant genotypes under stress conditions was the way to overcome water deficit stress under terminal drought conditions.","PeriodicalId":14383,"journal":{"name":"International Journal of Scientific Research in Environmental Sciences","volume":"44 7 1","pages":"209-219"},"PeriodicalIF":0.0,"publicationDate":"2014-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77729445","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}
