As a result, effective large-scale conservation is relying more on regional modeling and assessment. These regional approaches allow for evaluation of resource conditions over large areas and often have multiscale capabilities allowing examination of conditions at finer scales, within limits (Prior-Magee et al. 2007, National Fish Habitat Board, 2010, McKenna and Johnson 2011, McKenna et al. 2015). Data management and analysis limitations, as well as the scale of the problems to be addressed, require these broad-scale efforts to assume uniform average habitat conditions and/or species assemblages or populations within stream reaches (McKenna et al. 2006, Sowa et al. 2007, Kanno et al. 2014). Stream reaches (in the Great Lakes Region) are typically small (< 3 km) rarely exceeding 10 km. They may be clearly defined on a map by upstream and downstream confluences and are often the minimum reporting units for broad scale analyses. The National Hydrography Database (NHD) is widely used as a geographic foundation of these analyses and is an effective information management and analysis tool, allowing for association of local and broad-scale habitat and biological information with each stream reach within a region or the entire nation (Huang and Frimpong 2016). The NHD stream network consists of confluence-to-confluence stream reaches that range widely in length and vary with spatial resolution (e.g., 1: 100,000 or 1: 24, 000).","PeriodicalId":39335,"journal":{"name":"Open Ecology Journal","volume":"10 1","pages":"1-12"},"PeriodicalIF":0.0,"publicationDate":"2017-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42387139","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}

Merr and Tephrosia apollinea (L) Pers. Equally important was our investigation to quantitatively compare different germination parameters used for seed germination studies. The results showed that the final germination was highest for both species under chipping (CHIP), sand paper (SP) and 20 to 90 minutes in concentrated sulfuric acid (SA20 to SA90). Rubbing in sand (SAND) and water-soaking (SOAK) showed lower germination percentages. Mean germination time (MGT) was highest after 50 minutes in sulfuric acid (SA50) for both C. persica and T. apollinea. The coefficient of velocity of germination (CVG) was highest when seeds were treated with sulfuric acid during 30 minutes (SA30) for C. persica (56.1%) and during 60 minutes (SA60) for T. apollinea (66.8%). For the germination index (GI), chipping and all SA exposures (except 90 minutes) revealed high means for both C. persica and T. apollinea, while SP also resulted in high germination index for C. persica. The mean rate of seed germination was highest under sand rubbing and distilled water (0.9 and 0.8, respectively) for C. persica and under SA20 (1.3), for T. apollinea. The germination rate index (GRI) for C. persica was highest under CHIP, SP, and SA20 to SA60. Timson Germination Index (TGI) showed high values for most pre-treatments. The highest TGI recorded was 45.6% for SA30. As for the correlation between the germination parameters, it is recommended that final germination percent coupled with germination index are used as germination parameters. They do not require complex calculations, while they complement each other in giving a representative evaluation of seed germination.","PeriodicalId":39335,"journal":{"name":"Open Ecology Journal","volume":"9 1","pages":"13-21"},"PeriodicalIF":0.0,"publicationDate":"2016-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68056109","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 nosZ gene encoding the enzyme that reduces nitrous oxide to dinitrogen was utilized in this research, as molecular marker for denitrifying communities into low oxygen waters of Prado reservoir. Our objective was to analyze and compare the composition (richness and abundance) of nosZ-type denitrifiers in relationship with physicochemical variables (oxygen, pH, temperature, nitrate, nitrite and ammonium) in three areas of this dam: Isla del Sol, Lozanía and Tomogó which are distant and have different anthropogenic influences. For this, we performed DNA extraction, amplification, 454 pyrosequencing and phylogenetic analysis of nosZ gene. The Chao1 estimator and Shannon index were used for compare richness and diversity of nosZ gene; and the relationship between compositions of operational taxonomic units (OTU) with physicochemical variables was established by canonical correspondence analysis (CCA). In the reservoir 45 nosZ-OTUs to species level (80% similarity) were detected. Lozanía had the highest number of OTUs (25) and greatest diversity (SCHAO1: 35; H: 2.0), compared to the other areas sampling. The phylogenetic analysis showed the presence of many OTUs (28 of 45) with low similarity to Proteobacteria group and high similarity with sequences of environmental clones reported previously. The CCA showed that the nosZ-community composition of Prado dam was related with low pH (6.2), oxygen (0.01mg / L) and nitrate (<0.25 mg / L) recorded in the water column.","PeriodicalId":39335,"journal":{"name":"Open Ecology Journal","volume":"25 1","pages":"1-12"},"PeriodicalIF":0.0,"publicationDate":"2016-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68056067","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}

Population monitoring is challenging due to the vast expanse of the species ranges, tight budgets and limited availability of suitable fixed winged-aircraft. Consequently, many current population estimates are based on pragmatically designed ground-bound transect surveys. Although, ample literature exists on how to design surveys in an ideal world, little effort has been made to demonstrate the potential and limitations of a time-series of ground-bound transect surveys under real world constrains. Since 2003 we have been monitoring the two sympatric steppe ungulates, Asiatic wild ass (“khulan”, Equus hemionus) and goitered gazelles (“gazelle”, Gazella gutturosa), in the Great Gobi B Strictly Protected Area in south-western Mongolia using ground-bound line transects. Both species showed clear species-specific seasonal variation in group sizes which seem related to birthing and mating periods. Data on annual recruitment were impeded by the long flight distances and the difficulty to reliably identify and count young of the year. Distribution of khulans and gazelles showed clear speciesspecific seasonal patterns and highlighted the importance of two oasis complexes. Population estimates of 33 surveys covering 10,383 km2 were highly variable even between consecutive surveys and had huge 95% confidence intervals (khulan: range: 1,707 to 45,040, gazelles: range: 2,564 to 10,766) making them unsuitable to obtain robust baseline population estimates. Although our individual surveys were poor measures of population abundance, they provided important data on group sizes and species distribution and are presently used for Bayesian hierarchical trend modelling and species specific habitat suitability analysis. The ground surveys are relatively inexpensive as compared to aerial surveys and thus can be conducted at short temporal intervals, engaging park staff and researchers with local people thereby helping mutual understanding, information transfer, and detection of illegal activities.","PeriodicalId":39335,"journal":{"name":"Open Ecology Journal","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68056056","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 fragile nature of high latitudes is extremely vulnerable to human impacts. The negative effects are caused not only by plants and factories located in the northern latitudes but also by far away plants in Central Europe, America, and Asia. As a result, pollutants migrating to the Arctic significantly affect the environmental situation in the northern regions of the planet. In order to improve the environmental situation in the Arctic, environment quality has to be managed properly in all regions of the world. This article is focused on the analysis of the situation in the Arctic region of Russia, namely in the North of the Russian Plain. Starting from the 1980's, Russia has conducted environmental monitoring of the snow cover to determine critical pollutant loads on natural ecosystems across the country. A large amount of data has been accumulated allowing to carry out an in-depth analysis of the pollution of atmospheric precipitations and snow cover with acid-forming compounds. This article summarizes the results of research conducted from 1982 to 2013, including: 1) pollutant emission trends compared to available atmospheric air monitoring data, 2) spatial distribution of acidified precipitation occurrences, 3) neutralization probability, 4) calculation of sulphur deposition loads compared to the reference values proposed as criti- cal loads by the European Monitoring and Evaluation Program (EMEP)","PeriodicalId":39335,"journal":{"name":"Open Ecology Journal","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68054734","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}

This task can be fulfilled by developing an adequate systems analysis methodology where the gas industry is seen as a complex graph decomposed into separate subsystems for further investigation. Formulation of gas industry sus- tainable development strategy aimed at finding and validating the optimum balance between gas production and consump- tion and ensuring harmonious and synchronous development of the industry subsystems, cannot be completed without a relevant methodology. While developing the methodology, it is critical to apply geo-information systems, in which by synthesizing various data, can display the entire information on the long-term gas industry development programs. To es- timate cost-effectiveness of gas industry sustainable development strategy fundamental principles are applied. They in- clude modeling of cash flows associated with implementation of different projects and the need to consider fluctuations in the field of development costs and results generated in different periods of time using discounted cash flows. Since sys- temic risks management is a multi-stage iterative process with a corresponding risks analysis as its core component risks should be assessed and managed in consistency with multiple scenarios of the gas industry development. And, finally, the strategy implementation requires assessment of the geo-ecological risks associated with interaction of the 'gas industry- environment' system and quantitative methods for identifying and assessing the probability of risk occurrence.","PeriodicalId":39335,"journal":{"name":"Open Ecology Journal","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2015-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68056486","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}
