Biological soil crusts affect small-scale spatial patterns of inorganic N in a semiarid Mediterranean grassland
The influence of biological soil crusts (BSCs) on the small-scale spatial distribution of inorganic nitrogen (N) in drylands is largely unknown, despite their known impact and importance on the N cycle in these environments. We evaluated how perennial plants and BSCs affected small-scale spatial patterns of soil inorganic N (ammonium and nitrate) availability in a semiarid grassland from Spain....

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 کاملSpatial patterns of soil dC reveal grassland-to-woodland successional processes
Many grasslands and savannas around the world have experienced woody plant encroachment in recent history. In the Rio Grande Plains of southern Texas, subtropical woodlands dominated by C3 trees and shrubs have become significant components of landscapes once dominated almost exclusively by C4 grasslands. In this study, spatial variation of soil dC to was used to investigate patterns of transfo...
متن کاملArtificial root exudates and soil organic carbon mineralization in a degraded sandy grassland in northern China
Plant root exudates contain various organic and inorganic components that include glucose, citric and oxalic acid. These components affect rhizosphere microbial and microfaunal activities, but the mechanisms are not fully known. Studies concerned from degraded grassland ecosystems with low soil carbon (C) contents are rare, in spite of the global distribution of grasslands in need of restoratio...
