Remote sensing and GIS (geographical information systems) are very important methods for assessment of changes and development of ecosystems in the landscape level. This article deals with applying of remote sensing and GIS methods to assessment of ecosystems in agricultural landscape in the Horňácko region, extending to the White Carpathians Mountains Protected Landscape Area (Czech Republic)....

Neutral landscape models have many applications in ecology, such as supporting spatially explicit simulations, developing and evaluating indices. However, current approaches provide few options to produce large landscapes with controlled composition fragmentation We introduce flsgen (Fragmented Landscape Generator), a new neutral generator that addresses this limitation by providing high level ...

Quantifying landscape pattern and its change is essential for the monitoring and assessment of ecological consequences of land use change and human interference. The changing characteristics of landscape structure in the Haihe River Basin (HRB), China, during 1990 to 2000 were detected by using satellite remote sensing based land use data. Key landscape indices were selected to characterize the...

There is a long-standing quest in landscape ecology for holistic biodiversity metrics accounting multi-taxa diversity heterogeneous habitat mosaics. Passive acoustic monitoring of may provide integrative indices allowing to investigate how soundscapes are shaped by compositional and configurational heterogeneity mosaic landscapes. We tested the effects dominant on across large range landscapes ...

introduction conservation and management of landscapes and beautiful sceneries is one of the necessities of establishing and maintaining the protected areas. analysis of landscape visual quality has an important place in landscape planning and designing. in this way, reviewing effective criteria and discovering the simple patterns which affect the landscapes is the most important step of modeli...

The concepts of treewidth and tree-decomposition on graphs generalize those of the trees. It is well established that when restricted to instances with a bounded treewidth, many NP hard problems can be solved polynomially. In this paper, we study the treewidth of the NK landscape models. We show that the NK landscape model with adjacent neighborhoods has a constant treewidth, and prove that for...

Although a number of digital terrain analysis techniques were developed since the early 90ies terrain information is not utilized enough in landscape research even if topography is a key variable in a wide range of environmental processes. One explanation of this situation is the two-dimensionality of the main paradigm in landscape ecology, namely the patch-corridor-matrix model. Calculations o...

to apply scientific and proper management of rangeland ecosystems, having information on health and functions indices of ecosystem is required. using landscape function analysis, the present study deals with assessing and comparing of ecological indices in northern and southern landscapes, darehkonari khashab of gachsaran. length and width for ecological patches in northern landscapes  in speci...
