Direct and indirect influences of 8 yr of nitrogen and phosphorus fertilization on Glomeromycota in an alpine meadow ecosystem.
TLDR
The findings highlight the importance of soil fertility in regulating both plant and glomeromycotan communities, and emphasize that high fertilizer inputs can reduce the biodiversity of plants and AM fungi, and influence the sustainability of ecosystems. Expand
Effect of fencing and grazing on a Kobresia-dominated meadow in the Qinghai-Tibetan Plateau
Grazing is one of the most important factors influencing community structure and productivity in natural grasslands. Fencing to exclude grazers is one of the main management practices used to protectExpand
Herbivores and nutrients control grassland plant diversity via light limitation
TLDR
Testing the hypothesis that herbaceous plant species losses caused by eutrophication may be offset by increased light availability due to herbivory demonstrates that nutrients and herbivores can serve as counteracting forces to control local plant diversity through light limitation, independent of site productivity, soil nitrogen, herbivore type and climate.

Grassland productivity limited by multiple nutrients
TLDR
It is suggested that multiple-nutrient constraints must be considered when assessing the ecosystem-scale consequences of nutrient enrichment, and significant variations in the type and degree of nutrient limitation are pointed to. Expand
Seed mass and germination in an alpine meadow on the eastern Tsinghai–Tibet plateau
TLDR
It was evident that seed mass and germinability were strongly related to phylogeny, and it was suggested that correlates of ecology and phylogeny should be taken into account in comparative studies on seedmass and germination among species. Expand
The effects of long-term fertilization on the temporal stability of alpine meadow communities
TLDR
It is concluded that the presence of highly productive species that have stabilizing properties dominate fertilized assemblages and enhance ecosystem stability. Expand
Geographic variation in seed mass within and among nine species of Pedicularis (Orobanchaceae): effects of elevation, plant size and seed number per fruit
TLDR
In Pedicularis, elevation, plant size and seeds per fruit are all correlated with MISM among populations across species; this result calls into question the conclusions of studies that have detected geographic variation in MISM without controlling for variation in intrinsic factors. Expand
Impacts of altitude and position on the rates of soil nitrogen mineralization and nitrification in alpine meadows on the eastern Qinghai–Tibetan Plateau, China
Alpine and tundra grasslands constitute 7% world terrestrial land but 13% of the total global soil carbon (C) and 10% of the global soil nitrogen (N). Under the current climate change scenario ofExpand
Identifying response groups of soil nitrifiers and denitrifiers to grazing and associated soil environmental drivers in Tibetan alpine meadows
TLDR
This approach demonstrates the usefulness of the concept of response groups to better characterize and understand (de)nitrifier response to grazing. Expand
The effects of enclosures and land-use contracts on rangeland degradation on the Qinghai–Tibetan plateau
Rangeland degradation on the Qinghai–Tibetan Plateau is a growing concern, often attributed to climate change and overgrazing. A minority of researchers have suggested instead that degradation may beExpand
