Nitrogen (N) addition is an important nutrient strategy for alpine grassland in northwestern China to improve productivity livestock needs. A field experiment was conducted a semi-arid investigate the effect of N rates on soil N2O emissions over growing seasons 2017 and 2018. Treatments included six (0, 10, 30, 60, 120, 240 kg ha?1 y?1), which were applied before each season. The fluxes increas...

Season snow cover plays an important role in vegetation growth alpine regions. In this study, we analyzed the spatial and temporal variations seasonal start of growing season (SOS) grasslands preliminarily studied mechanism by which affects SOS changes modifying soil temperature (ST) moisture (SM) spring. The results showed that significant interannual trends SOS, end date (SED), days (SCD), ST...

The Source Area of the Yellow River is located in the mosaic transition zones of seasonally frozen ground, and discontinuous and continuous permafrost on the northeastern Qinghai–Tibet Plateau. Vertically, permafrost is attached or detached from frost action. The latter can be further divided into shallow (depth to the permafrost table 8 m), deep (>8 m) and two-layer permafrost. Since the 1980s...

In Taiwan, intensive forest fires frequently cause serious degradation, soil erosion and impacts on alpine vegetation. Post-fire succession often induces the substitution of by grassland. Alpine silver grass (Miscanthus transmorrisonensis Hay.) Yushan cane (Yushania niitakayamensis (Hay.) Keng f.) are two main endemic species emerging post-fire These play a major role in recovery vegetation con...

The northern Tibetan Plateau is the most traditional and important semi-nomadic region in Tibet. The alpine vegetation is sensitive and vulnerable to climate change and human activities, and is also important as an ecological security in protecting the headwaters of major rivers in Asia. Therefore, the Tibetan alpine grasslands have fundamental significance to both Mainland China and South Asia...

Changes in climatic conditions along geographical gradients greatly affect soil nutrient cycling processes. Yet how climate regimes such as changes in temperature influence soil nitrogen (N) and phosphorus (P) concentrations and their stoichiometry is not well understood. This study investigated the spatial pattern and variability of soil N and P availability as well as their coupling relations...

Since 2007, the Silvretta Archaeological Project in the high Alps on the Swiss-Austrian border has been investigating the prehistoric origins of alpine pasture economy. In an area of about 540 km2 more than 20 well-preserved archaeological sites associated with alpine pastoralism have been recorded, the earliest of them dating to the Iron Age (Reitmaier (ed.), 2012; Walser and Lambers, 2012). A...
