A habitat-riparian index system (HIS) is a newly developed metric to estimate stream naturalness in Korea. In this study, we focus on a predictive assessment of the HIS associated with stream integrity, and then aim to evaluate essential features of the stream integrity in conjunction with ambient land use patterns obtained from geographical information system (GIS). Concerning the stream health assessment, we applied a decision-tree model to the HIS prediction. As a results, the best models of the decision-trees exhibited a 72.2% accuracy in prediction of the stream health index, and also a 65.8% accuracy in classifying river catchments. A hierarchical structure of the decision tree models in effect, was able to identify and classify more influential land use patterns that could reflex stream integrity. We highlight that GIS-involved analyses and approaches accommodates a wide variety of benefits in a rapid assessment of ecological data associated with field measurements. Furthermore, such methodological applications will be able to become an effective alternative for efficient ecological health assessment in streams and rivers.","PeriodicalId":11598,"journal":{"name":"Ekoloji","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70623563","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}

Carbon (C) mineralization was measured with the CO2 respiration method at 28°C over 30 days. The nitrogen (N) mineralization was also measured in vitro both in the soils with the two parent materials of Ceratonia and Pinus under controlled conditions (42 days, 28°C and 80% of field capacity). There were significant differences between the two parent materials for both Ceratonia and Pinus in terms of the carbon mineralization ratio (%) in all sampling periods except for July 2012 for Ceratonia. These results might be clarified with the effects of different parent materials and plants. Interactions between incubation time, incubation time × plant were significant (P= 0.007 and P= 0.001 levels), respectively for the microbial respiration. The contents of NO3-N were higher than those of NH4- N in all soils. With these results it might be explained that environmental factors in both soils for NO3-N are quite suitable for the microbial activities of both Pinus and especially Ceratonia.","PeriodicalId":11598,"journal":{"name":"Ekoloji","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70623839","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}

Soil fauna samples were extracted with a modified Berlese-Tullgren funnel and stored in 70% ethanol. A total of 26 taxons of microarthropods were identified in the oak stand and Scots pine plantation. The mean annual number of microarthropods per square meter was 42.851 for the oak stand versus 42.276 for the Scots pine plantation. The Collembola and Acarina are the two dominant taxa in numbers constituting 94% and 93% of all soil microarthropods of the native oak and Scots pine plantation, respectively. The Shannon diversity index (H') of microarthropods in the Scots pine site (1.72) was found significantly (P=0.008) higher than those of the native oak (1.57).

It is the second largest lake in Turkey. The lake is located within the boundaries of three cities, Aksaray, Konya, and Ankara. With-in the study area, there are 64 residential areas. Tuz Lake is located in a closed basin and has a geologically tectonic origin. The Lake and the surrounding areas were declared as an area of natural importance in 1992 and consequently as a Special Environmental Protection Area(SEPA), in 2000 was designated as the largest in the country with 7,414 km². The aim of this study was to determine the habitat types in the study area according to the European Nature Information System (EUNIS) and identify the changes in these habitat types for the last 20 years using the Geographic Information Systems (GIS) and Remote Sensing (RS) techniques. As a result, 12 EUNIS habitat types and the changes in these habitats for the year 1987 and 2007 were determined. Habitat types for 1987 and 2007 remained the same (12) but, the Surface Running Waters (C2) habitats in 1987 were transformed into small–scale ornamental and domestic garden areas (I2.2) in 2007.

Two blast trials, one with a classical drill cuttings stemming method and new plaster stemming method were carried out and the environmental and ecological effects were measured in terms of vibration and air shock and observed flying rock. The results were evaluated in terms of environmental and ecological values. In the one series of blast tests, the blast cost was reduced to 16 % by increasing the burden and spacing distance for the unit volume rock. In this way, 21% more blast area and the 21% more rock was obtained with the same hole-drilling. It means that lesser drilling and lesser blasting results in lesser environmental and ecological effects for obtaining the unit volume rock.\u0000Blast trial with plaster stemming produced less oversize material. For instance, +30 cm size fragments reduced to 5.4 % compared to 37.7 % in the conventional method of classical drill cutting stemming. In the next process, both the product can be broken and ground more profitable and especially the dust problem and other grinding and breaking induced environmental and ecological damage will be reduced. Therefore, it is expected that the new stemming method will commonly be preferred in the future. Using the new plaster stemming method, in spite of the 88 m measuring distance, vibration, and air shock values increased in the Peak Particle velocity (PPV) value from 12.0 mm/s to 17.8 mm/s and in the air shock value from 132 dB to 132.9 dB by directing more blast energy to rock breakage. Firstly in spite of it being seen as a disadvantage, it is not a disadvantage because of the total work (lower specific charge and specific drilling). In other words, we can obtain the same rock with lesser drilling and lesser explosives. In addition, these increased values were small and under the permitted limit of blast damage criteria in spite of the short measuring distance. Within the blasting area especially the birds, mammals, plants, as well as other living organisms can be affected. In terms of reducing the bad effects of blasting on the biological diversity, the new method provides successful and encouraging results because of a lower specific charge and specific drilling.","PeriodicalId":11598,"journal":{"name":"Ekoloji","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70623047","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}
