However, the mean SUVA of the DOC was 0.55 +/- 0.33 L mg(-1) m(-1), showed a comparatively low aromaticity among wetlands. Significant variations of DOC concentration and their SUVA were both found under different spatial scales. The results showed that both the concentration and aromaticity of the DOC are influenced by the water table in the peatland. The significant difference of the DOC concentration among the three types of wetland showed the influence of plant growth on the DOC in the soils, and the SUVA indicated the different sources of the DOC in the different wetlands. The results also indicated that the DOC concentrations in stream water are consistent to the proportion of peatlands in the corresponding catchment.","PeriodicalId":11598,"journal":{"name":"Ekoloji","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70622194","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}

In this study, two types of soils were selected, first not exposed (NE) to Imazamox previously and the second Imazamox treated peanut soil (P). The recommended field dose [(RFD), 40 g L -1 active ingredient], 2 × RFD, and 4 × RFD of this herbicide were added to the NE and P soil. The microbial activities of the soils were measured by carbon and nitrogen mineralization under two different humidity conditions [60% and 80% of field capacity (FC)]. Carbon mineralization was determined by the CO 2 respiration method at 30°C over 45 days. Mineralization ratios (%) of carbon in all herbicide doses of P humidified at 60% and 80% FC were significantly higher than all the other dose–humidity combinations of NE soils (P<0.001). Despite the NH4-N, there were significant differences between the NO3-N contents of these two soils (P≤0.05). These results showed that nitrate producing bacteria were still very sensitive to foreign compounds added to the soils. These results suggest that soil microorganisms consumed the Imazamox as C and/or N sources without being effected by different humidity conditions.","PeriodicalId":11598,"journal":{"name":"Ekoloji","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70622245","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}

For this purpose, the A. aquaticus samples are collected by choosing three stations along the Saricay Creek, some of whose regions are exposed to domestic and industrial pollution. Sampling stations are chosen from regions that are interpreted as polluted or clean according to the heavy metal content and physico-chemical parameters where the A. aquaticus individuals live. After the determination of species is performed, the heavy metal (Cu, Fe, Cd, Pb, and Zn) and biomarker (Na+/K+-ATPase, Glutathione, and TBARS) analyzes were made. According to the water quality analysis, S3 was the most polluted station, S2 was a moderately polluted station, and S1 was determined as a clean station. A considerable increase in the amount of glutathione (GSH) was detected in the S2 and S3 stations in parallel with the increase of pollution. However, there were no statistical differences in the TBARS levels as an indicator of lipid peroxidation and Na + /K + -ATPase enzyme activity. The significant increase (three-fold) of the GSH levels in the polluted areas indicates that water pollution causes oxidative stress in the A. aquaticus species.

Sampling took place monthly at four stations between December 2006 and December 2007. During the study period, a total of 58 taxa of which 52 were used as active taxa in the numerical analysis (relative abundance>1%) were from four algal classes, Cyanophyceae, Dinophyceae, Bacillariophyceae, and Euglenophyceae. In general, the most important groups were diatoms and dinoflagellates in terms of species numbers and abundance. The mean Shannon-Weaver’s diversity index (H') and Pielou evenness index (J') values were 2.35 and 0.83, respectively. An abundance of the bloom of certain phytoplankton species, especially Cylindrotheca closterium and Navicula sp., was thought to be the cause of the low diversity index and evenness values. Although nitrogen was thought to be limiting in temperate regions, phosphorus was a limiting factor on the phytoplankton growth in the Homa Lagoon because of the correlation between the abundance and N/P ratio. The relationship between the phytoplankton communities and 10 environmental variables were researched using a canonical correspondence analysis (CCA). According to the Monte Carlo unrestricted permutation test, the temperature and nitrate concentration were the most important variables in accounting for species distribution.","PeriodicalId":11598,"journal":{"name":"Ekoloji","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70621406","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}

In this study, the effect of growth medium of natural hazelnut husk compost enriched with organic fertilizer at different ratio on cultivation of garden cress was researched. Organic fertilizer was added to hazelnut husk compost (adjusted to by volume 5%, 10%, 15% and 20%) in the manner that nitrogen would be 1%, 2%, 3% and 4% by using the nitrogen content of growth medium as a base. Natural hazelnut husk was accepted as a control application. In the study which was coordinated as a pot trial, each pot was examined as a replication and the study was carried out according to randomized parcels base design with three replications. In the study, seed plantings (2 g/m2) were made in two different seasons; spring and autumn. Autumn planting was made in 10 September 2008 and spring planting was made in 28 April 2009. Plants were harvested two times for each two seasons. After harvest was finished, plant yield, leaf width, leaf length, vitamin C and leaf color (chroma, hue) values were determined. In the study, organic fertilizer applications statistically increased yield and leaf quality. In terms of yield value, 2% N application with 2052 g/m 2 gave the highest yield. Yield and leaf width values were higher in the first harvests. All fertilizer applications increased garden cress width and length. Amount of vitamin C increased 80% according to the control in 2% N application. Fertilizer addition created more green leaves on plants. Usage of organic fertilizer added natural hazelnut husk in the cultivation of garden cress is important in terms of both plant yield and quality improvement, and environmental sustainability.","PeriodicalId":11598,"journal":{"name":"Ekoloji","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2014-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70621116","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}
