In order to know about essence of forest and grassland ecosystem and provided theory for forest mixed with grassland. The result shows that:The function of plant absorption influences severely the soil available N. The variety of N content of T.tomentosa and L.multiflorum is the same. The N ...
Many ecosystems can be viewed as lying within a continuum between grassland and forest, where ground coverage by woody plants (trees and shrubs) ranges from non-existent to complete. Patterns of energy, water, and biogeochemistry are often heterogeneous between canopy patches beneath woody plants and...
flooding, hurricanes, etc) are frequent. A pyric climax refers to an ecosystem that never reaches the potential climax vegetation defined by climate because of frequent fires. The ecotone, a boundary, between grasslands and forests, is a pyric climax, and only with fire suppression...
Forests provide a plethora of ecosystem services and are indispensable to the anthroposphere and the biosphere1,2,3,4,5,6. However, forests consume water for physiological functioning and growth, thus they might potentially deplete Earth’s water resources7,8,9,10. Conceptually, forest communities...
Comparisons were made among Douglas-fir forest, aspen (broad leaf deciduous) forest and wheatgrass (C 3 ) grassland for ecosystem-level water-use efficiency (WUE). WUE was defined as the ratio of photosynthetic CO 2 assimilation rate and evapotranspiration (ET) rate. The ET data measured by ...
The purpose of this thesis was to classify and describe low-elevation grassland and shrubland vegetation, mid-elevation woodland and forested vegetation, and high elevation alpine vegetation associations of the Beartooth Mountains study area and to compare newly derived associations with existing habitat ...
example, while afforestation of Irish peatlands and grasslands of high conservation value was considered detrimental for bird biodiversity, in the case of intensively managed grassland, afforestation can lead to higher densities of bird species of conservation concern (Graham et al.2017). Such nuanced...
past 10 years, while 11 million hectares of grassland were improved and more than 800,000 hectares of wetlands were added or restored. From the tree planting programs to the world's largest artificial plantation, the Saihanba mechanized forest farm, China has been striving ...
