Spatial distribution of fungal communities in a coastal grassland soil
In grasslands, saprotrophic fungi, including basidiomycetes, are major decomposers of dead organic matter, although spatial distributions of their mycelial assemblages are little described. The aim of this study was to characterise the scale and distribution of saprotrophic fungal communities in a coastal grassland soil using terminal restriction fragment length polymorphism (T-RFLP). Soil fung...
متن کاملPrecipitation and aridity index regulating spatial patterns of vegetation production and species diversity based on alpine grassland transect, Tibetan Plateau
31 Although the relationship between the aboveground net primary production (ANPP) and species 32 diversity (SR) have been widely reported, there is considerable disagreement about the fitting 33 patterns of SR–ANPP, which has been variously described as ‘positive’, ‘negative’, ‘unimodal’, 34 ‘U-shaped’ and so on. Not surprisingly, the effect-factors including precipitation, aridity index and 3...
متن کاملVariation of soil hydraulic properties with alpine grassland degradation in the Eastern Tibetan Plateau
Ecosystems in alpine mountainous regions are usually more vulnerable and easily be disturbed by environmental change globally. Alpine swamp meadow, a unique grassland type in the eastern Tibetan Plateau which provides important ecosystem services to the upstream and downstream regions of international rivers of Asia even the world, is undergoing severe degradation, which can dramatically alter ...

Effects of permafrost degradation on alpine grassland in a semi-arid basin on the Qinghai--Tibetan Plateau
Permafrost on the Qinghai–Tibetan Plateau (QTP) has degraded over the last few decades. Its ecological effects have attracted great concern. Previous studies focused mostly at plot scale, and hypothesized that degradation of permafrost would cause lowering of the water table and drying of shallow soil and then degradation of alpine grassland. However, none has been done to test the hypothesis a...
