Disturbed deciduous forests with impoverished soils, a limited seed bank, or genetically degraded forest sites, may require active restoration (Joyceet al.2001). This process is needed when conditions cannot allow for natural regeneration to occur. Large areas extensively exploited for agriculture, for...

detection of radiationTime-dependent DFT (TD-DFT), CIS, and CASSCF calculations of the excited singlet states of diphenylacetylene demonstrate the existence of a low energy crossing between the initially excited pipi* state (1 B-1(1u) in D-2h) and the dark pisigma* state (1 (1)A(u) ...
(for example, building roads through a forest). Fragmentation generally leads to small, isolated patches of hospitable habitat. Smaller habitats support fewer species and smaller populations, which are at greater risk of inbreeding and local extinction. The theory of island biogeography predicts that ...
In many parts of Korea, forest vegetation near industrial complexes began to show symptoms of decline in the 1970s, when active industrialization was begun (National Institute of Environmental Research, 1981; Lee, 1992). These symptoms also appeared in urban areas that have experienced chronic air...
Forest restoration through reintroduces tree species lost, especially fast growing dipterocarp is implemented to curtail degraded logged-over forest and improve the soil fertility through organic material application is important, but only few information is available on restoration of degraded forest. The...
Land degradation is a serious threat to agriculture which is adversely affecting the soil functions and productivity, while degraded soils stretch up to 6 billion ha worldwide. The population of the world is increasing day by day and agricultural land is declining due to degradation. It is estima...
