In forests, termites serve as “soil engineers,” translocating mineral soil to the surface, constructing macropores to improve water infiltration, increase soil minerals and organic carbon, facilitate the growth of microbes and affect the growth of vegetation. The future productivity of a forest site therefore depends to some degree on termite activity. termites could reduce the probability of f...

poplar trees are appropriate species for plantation and forest rehabilitation because of fast growing and high wood yield, as well as adaptability to unfavorable climate. salinization of soil and high temperature are the inhibitory factors in khuzestan province. populus euphratica is a tree species that tolerates soil salinity and high temperature. acclimatization of cut seedling of three popul...

Tropical forests are major contributors to the terrestrial global carbon pool, but this pool is being reduced via deforestation and forest degradation. Relatively few studies have assessed carbon storage in degraded tropical forests. We sampled 37,000 m(2) of intact rainforest, degraded rainforest and sclerophyll forest across the greater Wet Tropics bioregion of northeast Australia. We compare...

The purpose of this study was to investigate the impacts of forest-based activities on the conditions of the Ganaveh woodland in the southern Zagros, Iran, and to suggest strategies for improving the implementation of forest resource management plans. Woodland inventory data was gathered in 2003, accompanied with data from interviews in 2008, were used in this study. The results show that there...

In British Columbia, soil rehabilitation aims to restore productivity to forest roads, landings, and trails that are no longer needed for access, and to areas that have suffered unavoidable or accidental damage as a result of forestry operations. Soil rehabilitation is an important component of management strategies to maintain or enhance timber supply in the working forest. Restoring productiv...

This review explores the ecological and silvicultural impacts of ice storms on forests in the southern United States. Different environmental factors like weather conditions, topography, vegetation, stand density, and management practices influence the degree of glaze damage a particular forest may experience. Additionally, the frequent contradictions in the relationships between these factors ...

Soil microbial community characterization is increasingly being used to determine the responses of soils to stress and disturbances and to assess ecosystem sustainability. However, there is little experimental evidence to indicate that predictable patterns in microbial community structure or composition occur during secondary succession or ecosystem restoration. This study utilized a chronosequ...

BACKGROUND Resources for home care rehabilitation are limited, and many home care clients who could benefit do not receive rehabilitation therapy. The interRAI Contact Assessment (CA) is a new screening instrument comprised of a subset of interRAI Home Care (HC) items, designed to be used as a preliminary assessment to identify which potential home care clients should be referred for a full ass...
