Land degradation and discontinuation of ecosystem services (ES) are a common phenomenon that causes socio-economic environmental problems in Ethiopia. However, dearth information is known about how ES changing from the past to future with regard land use cover (LULC) changes. This study aimed at estimating values based on LULC changes central Maximum likelihood classifier cellular automata-arti...
Genetic transformation is a natural process during which foreign DNA enters a cell and integrates into the genome. Apart from its relevance for horizontal gene transfer in nature, transformation is also the cornerstone of today's recombinant gene technology. Despite its importance, relatively little is known about the factors that determine transformation efficiency. We hypothesize that differe...
The concept of the city's landscape is connected with the objectivity and subjectivity of that city. Therefore, in order to manage this concept at night, in addition to functional-physical manifestations of the city, we should focus on the perceptual issues of citizens, which may have roots in their ancient identity, religion and customs. By accepting this hypothesis, a suitable model for night...
Transformation of natural land cover (LC) into modified LC has become inevitable due to growing human needs. Nevertheless, landscape transformational patterns during reclamation of mine damaged lands remain vague. Our hypothesis was that post-mining landscapes with different ages since dumping become more diverse in LC transformation over time. The aim was to study the impact of landscape recla...
Analyzing spatial and temporal changes in landscape patterns is an important aspect of landscape ecology. We used satellite imagery and ERDAS Image software, calculated landscape indices, and quantified landscape transformation processes to determine the nature and magnitude of landscape structural changes within an upland area of the Taishan Mountains in Shandong province, eastern China. We us...
Ongoing landscape transformation is one of the major causes behind disappearance of traditional landscapes, and lead to species and resource loss. Tree in paddy fields in the northeast of Thailand is one of those traditional landscapes. Using three different historical time layers, we acknowledged the severe deforestation and rapid urbanization happened in the region. Despite the general thinki...
First-principles calculations are presented for parent B2 phase and martensitic B19 and B190 phases in NiTi. The results indicate that both B19 and B190 are energetically more stable than the parent B2 phase. By means of ab initio density functional theory, the complete distortion–shuffle energy landscape associated with B2? B19 transformation in NiTi is then determined. In addition to accounti...
Transformation of the glaciated isthmus between Sørkapp Land and the rest of Spitsbergen since 1900 is described. The landscape-seascape dynamics depends on the glacial recession determined by climate warming after the Little Ice Age (i.e., since the beginning of the twentieth century, and especially since the 1980s). The isthmus has been narrowed from 28 km in 1899-1900 to 6.2 km in 2013, and ...
urban growth and associated landscape transformation has been a major driver of local, regionaland global environmental change. the conversion of urban greenery to impervious landscapes has been identifiedas a key factor influencing the distinctive urban heat and associated consequences. due to the often highdemand for space in urban areas, creation and preservation of urban greenery as heat si...
The unique geography and climatic condition determines the landscape environment characteristics of mountain village in western China. In recent years, with the fast development of the urban-rural integration and urbanization process, the traditional rural landscape is gradually transiting to the modern rural landscape. In the course of transformation, the natural patches and semi-natural patch...
