Impacts of shrub encroachment on ecosystem structure and functioning: towards a global synthesis.
It was revealed that encroachment had mixed effects on ecosystem structure and functioning at global scales, and that shrub traits influence the functional outcome of encroachment.
Biological Soil Crusts: Ecology and Management
In the technique for fiberizing glass by the use of a centrifugal spinner delivering glass streams into an attenuating blast, a novel spinner construction is provided, and provision is also made for
Disturbance and Recovery of Biological Soil Crusts
Disturbance can profoundly affect the cover, species composition, and the physiological functioning of biological soil crusts. The disturbances we discuss include air pollution; exposure to oil,
Plant Species Richness and Ecosystem Multifunctionality in Global Drylands
A global empirical study relating plant species richness and abiotic factors to multifunctionality in drylands, which collectively cover 41% of Earth’s land surface and support over 38% of the human population, suggests that the preservation of plant biodiversity is crucial to buffer negative effects of climate change and desertification in dryland.
Microbiotic soil crusts: a review of their roles in soil and ecological processes in the rangelands of Australia
Microbiotic crusts are assemblages of non-vascular plants (mosses, liverworts, algae, lichens, fungi, bacteria and cyanobacteria) which form intimate associations with surface soils. They play a
Decoupling of soil nutrient cycles as a function of aridity in global drylands
Any predicted increase in aridity with climate change will probably reduce the concentrations of N and C in global drylands, but increase that of P, suggesting the provision of key services provided by these ecosystems could be negatively affected.
A global atlas of the dominant bacteria found in soil
This study narrows down the immense number of bacterial taxa to a “most wanted” list that will be fruitful targets for genomic and cultivation-based efforts aimed at improving the understanding of soil microbes and their contributions to ecosystem functioning.
Dryland ecohydrology and climate change: critical issues and technical advances
Drylands cover about 40 % of the terrestrial land surface and account for approximately 40 % of global net primary productivity. Water is fundamental to the biophys- ical processes that sustain
Germination and seedling establishment of two annual grasses on lichen-dominated biological soil crusts
The results clearly demonstrate that lichen-dominated biological soil crust can inhibit germination and root penetration, but the extent of these effects depends on the composition of the crust.
Structure and functioning of dryland ecosystems in a changing world.
This synthesis highlights the importance of biotic attributes (e.g. species richness) in maintaining fundamental ecosystem processes such as primary productivity, illustrates how N deposition and grazing pressure are impacting ecosystem functioning in drylands worldwide, and highlights the role of the traits of woody species as drivers of their expansion in former grasslands.
