Abstract Purpose Owing to their topographic location and nutrient rich soils, riparian forests are often converted pastures for grazing. In recent decades, remnant cleared grazing have been restored with native species. The impacts of such land-use changes on soil fungal communities unclear, despite the central roles that fungi play in key ecosystem processes. We investigated how taxonomic func...
Nature conservation requires classification of vegetation types for site assessment and assignment. Species-rich floodplain meadows are a declining habitat in Britain Europe yet their has been based on just few samples fails to describe community response environmental change adequately. European classification, opposite, from the wide geographical range with no data/analysis supporting choices...
The abundance and diversity of archaeal assemblages were analyzed in soils collected from Gyorae Gotjawal forest, Jeju, Korea. Gotjawal soil refers to soil derived from a lava-formed forest, characterized by high organic matter content, fertility, and poor rocky soil. Using domain-specific primers, archaeal 16S rRNA gene sequences were PCR amplified for clone library construction, and a total o...
A method is proposed to transform the red and near infrared data into a soil index in order to map soil features. The index maximises soil variation and helps improve soil feature mapping while it suppresses spectral response from vegetation cover. Geo-statistical analysis of fi eld data, on the other hand, helps understand spatial dependency pattern and map it, which may not be directly visibl...
The impacts of fragmentation and recreational use on the hemiboreal urban forest understorey vegetation and the microbial community of the humus layer (the phospholipid fatty acid (PLFA) pattern, microbial biomass and microbial activity, measured as basal respiration) were examined in the greater Helsinki area, southern Finland. Trampling tolerance of 1) herb-rich OMT, 2) mesic MT, and 3) sub-x...
Climate change, initiated by increasing greenhouse gas emissions leads to serious ecological and economic problems especially in developing countries. The potential carbon sinks are analyzed by a combination of different remote sensing based products for three countries (Ghana, Togo, Burkina Faso). In order to derive these information, the following analysis need to be done: Firstly, the net pr...
Agricultural yields can be predicted from detailed multi-year remote sensing image sequences using measured features of vegetation conditions. In this paper, the dependency between the moment of prediction and the accuracy of the forecast is studied. The linear model is selected as a basic approach of yield forecasting. Then, the model is extended with non-linear components (factors) in order t...
myths are reflective of human concerns and needs during ancient times. by reviewing them, it turns out that many human problems today, have a historical background. among the main themes of ancient mythologies, fertility and reproduction have various representations in ancient civilizations. the purpose of this paper was to review myths and common symbols of fertility and reproduction in ancien...
This paper’s working hypothesis is that the indigenous farming practices of Timorese farmers are those most suitable and adaptable with regard to these farmers’ circumstances. Intensive acceleration land conversion in Java lead a reduction favorable cropland degradation soil biology. To meet demand for food production, unfavorable areas outside Java, including marginal semi-arid on Timor Island...
Air is our main contact with the environment in which wefind ourselves. Every day, we breathe in 15 kg of air; that’s more than our daily food intake. Air, in cities and confined environments where houses are really close together, consists of particles of different sizes charged of chemical pollutants. The finer particles will come into contact with the alveoli and will allow some pollutants g...
