Analysis of a 30-year rainfall record (1967-1997) in semi-arid SE Spain for implications on vegetation
In order to understand the behaviour of ecosystems in semi-arid areas, rainfall must be analysed over time. For this reason, statistical methods were applied to a rainfall time-series (1967–1997) inExpand
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.

Ecology and functional roles of biological soil crusts in semi-arid ecosystems of Spain.
The growing body of research on BSCs available from semi-arid areas of Spain is reviewed, highlighting its importance for increasing the authors' knowledge on this group of organisms and how it can be use to guide management and restoration efforts. Expand
Do changes in rainfall patterns affect semiarid annual plant communities
Abstract Question: Climate change models forecast a reduction inannual precipitation and more extreme events (less rainydays and longer drought periods between rainfall events),which may haveExpand
Seed Bank and Understorey Species Composition in a Semi-arid Environment: The Effect of Shrub Age and Rainfall
Understorey vegetation in patches of Retama sphaerocarpa shrubs in semi-arid environments is dependent on the overstorey shrub life history and the eAect of the canopy on understorey species diversity in the field and its relationships with the soil seed bank is investigated, suggesting that the soil Seed Bank is rather uniform and that the shrub canopy strongly selects which species appear in theunderstorey.

The influence of competition between lichen colonization and erosion on the evolution of soil surfaces in the Tabernas badlands (SE Spain) and its landscape effects
ARTICLE I NFO Badlands often contain a mosaic of soil surface types with contrasting hydrological behaviour which drives their short term geomorphic evolution. The Tabernas badlands, in semiarid SEExpand
Changes in biocrust cover drive carbon cycle responses to climate change in drylands.
The dramatic reduction in biocrust cover with warming will lessen the capacity of drylands to sequester atmospheric CO2, and may act synergistically with other warming-induced effects, such as the increase in soil CO2 efflux and the changes in microbial communities to alter C cycling in drylands, and to reduce soil C stocks in the mid to long term.

Crust Composition and Disturbance Drive Infiltration Through Biological Soil Crusts in Semiarid Ecosystems
Soil crusts influence many soil parameters that affect how water moves into and through the soil, and therefore, critically influence water availability, erosion processes, nutrient fluxes, andExpand
European small portable rainfall simulators: A comparison of rainfall characteristics
Small-scale portable rainfall simulators are an essential research tool for investigating the process dynamics of soil erosion and surface hydrology. There is no standardisation of rainfallExpand
Soil–geomorphology relations in gypsiferous materials of the Tabernas Desert (Almerı́a, SE Spain)
A detailed pedological study in an apparently homogeneous badlands area of gypsiferous mudstones in the Tabernas Desert (Almeria, SE Spain), with an annual precipitation of 200 mm, has been shown toExpand
