Conservational management practices in grasslands have been considered one of the efficient options to enhance the soil organic carbon (SOC) accumulation. However, the SOC changes after the conservational management practices vary significantly under different grassland vegetation types and the environmental conditions. At present, it is not clear how the SOC accumulation changes along the soil...

Pollen analysis suggests that in central South Island the late Otiran landscape on both sides of the Main Divide was dominated by grassland. An outstanding exception is the presence of Nothofagus menziesii forest at Blue Spur Road, Hokitika. The grassland persisted from about 26000 years to about 12000 years ago and during this time there was little variation in the character of the vegetation....

and abandonment is causing considerable woodland expansion in many mountainous areas of Europe, with potential repercussions on conservation-sensitive species typical of open habitats. We examined the potential impact of such changes on an alpine golden eagle population, by estimating the ranges potentially used by the eagles for foraging through different techniques (concentric circles of diff...

Iran is a mountainous country. Hezar Mt., is an isolated mountain with the highest peak of 4465 m (above sea level) located in southeast of Iran. This paper aims to provide a general overview of alpine phytodiversity of Hezar Mt. Alpine regions are above timber-line which is dependent on the climate, slopes and human activities. The timberline at Hezar Mt., is varying from 3200 m (North slope) ...

Root turnover is an important carbon flux component in grassland ecosystems because it replenishes substantial parts of carbon lost from soil via heterotrophic respiration and leaching. Among the various methods to estimate root turnover, the root's radiocarbon signature has rarely been applied to grassland soils previously, although the value of this approach is known from studies in forest so...

Soil erosion in the Three-River Headwaters (TRH) region has continued to intensify recent decades due human activities and climate change. To reverse this situation, Chinese central government launched Subsidy Incentive System for Grassland Conservation (SISGC). As a sign of effectiveness SISGC implementation, dynamic changes soil can provide timely feedback decision makers managers. The Revise...

Community dominant plants and their ecological niche research is the focus of community ecology research. To explore characteristics desert relationship between them soil factors in Qaidam Basin, to provide a basis for construction plant communities sustainable management natural resources Basin. Taking 13 Qinghai Province as objects, this paper analyzed species based on physical chemical prope...
