Fire in Semi-Arid Shrublands and Woodlands: Spatial and Temporal Patterns in an Australian Landscape
Semi-arid landscapes are of interest to fire ecologists because they generally located in the climatic transition zone between arid lands (where fires tend be rare due lack fuel, but enhanced following large rainfall episodes) and more mesic regions activity tends severe deficits). Here we report on characteristics contemporary regimes operating a semi-arid region inland south-western Australia...
Soil biogeochemical processes have the potential to impact water quality in source areas of diversion projects. This study aimed explore differences biochemical and mechanisms at microaggregate scale for different land use types area China's Middle Route South-to-North Water Diversion Project. The compared four typical types—forests, shrublands, terraces, cultivated land—by characterizing micro...
Fire is recognized to be an important disturbance in many ecosystems worldwide, although desert are not generally thought of as being prone fire, primarily because the lack a continuous fuel bed. However, likelihood catastrophic fires some systems increasing due spread exotic species, which can grow open. A second factor fire risk may extreme rainfall events caused by climate warming that lead ...

Communities of plants, biological soil crusts (BSCs), and arbuscular mycorrhizal (AM) fungi are known to influence soil stability individually, but their relative contributions, interactions, and combined effects are not well understood, particularly in arid and semiarid ecosystems. In a landscape-scale field study we quantified plant, BSC, and AM fungal communities at 216 locations along a gra...
