The aim of the research is to analyse the landscape structure changes from the end of the Soviet times in 1974– 1986 until 2005 when market economy existed in Lithuania. The changes of landscape structure were observed in 100 sample areas (squares) each of them having 2.5 km area and distributed in different landscape types. The changes in sample areas (squares) with determination of land cover...

Epiphytes are strongly affected by the population dynamics of their host trees. Owing to the spatio-temporal dynamics of host tree populations, substantial dispersal rates--corresponding to high levels of gene flow--are needed for populations to persist in a landscape. However, several epiphytic lichens have been suggested to be dispersal-limited, which leads to the expectation of low gene flow...

Increasing habitat fragmentation poses an immediate threat to population viability, as gene flow patterns are changed in these altered landscapes. Patterns of genetic divergence can potentially reveal the impact of these shifts in landscape connectivity. However, divergence patterns not only carry the signature of altered contemporary landscapes, but also historical ones. When considered separa...

sarygamesh basin one of the bulhary chay tributary take place in moghan plain, northeastern azarbyjan area in iran and south edge of kora- araz zone. aims of this research are study specificities and geomorphic evolution of sarygamesh basin, survey rivers work on structure and geologic formation, and corresponding hydrographic with earth structure. toward above aim is used to litologic, structu...

Landscape connectivity combines a description of the physical structure of the landscape with special species’ response to that structure, which forms the theoretical background of applying landscape connectivity principles in the practices of landscape planning and design. In this study, a residential development project in the southern United States was used to explore the meaning of landscap...

Ecologists can be overwhelmed by the number of metrics available to quantify landscape structure. Clarification of interrelationships and redundancy is needed to guide metric selection and interpretation for the purpose of landscape monitoring. In this study we identified independent components of classand landscape-level structure in multiple landscapes in each of three large and geographicall...
