Wild cereals have been harvested all over the world by hunter-gatherer with evidences as much in South America as in Australia, North America and Subsaharian Africa. In some places there are still used for human consumption. ...

In arid and semi-arid ecosystems that are frequently classified as water limited, it is unclear how spatial and temporal variability of vegetation and climate could affect microbially-mediated soil processes. Our objective ...

In arid and semi-arid regions, the climatic impact on lakes is especially critical, as they are scarce and play an important role as a primary source of the water supply. However, in some extended regions with those climatic ...

The biodiversity–ecosystem function literature provides a useful framework to examine many processes associated with species diversity in ecology. One such context is the maintenance of biodiversity by facilitation in arid ...

Debris flows triggered from rapid melt of seasonal snow, and/or ice within the active layer have not been studied in periglacial areas of the semi-arid Andes. Therefore, through a representative watershed we investigated ...

There is a wide consensus that arid and semi-arid environments are highly variable in space and time. The most frequent approaches to describe and analyze arid and semi-arid rangelands are based on the usage of averages ...

An integral, glacial and periglacial, inventory of the cryosphere in the Atacama region in Chile was carried out to estimate the amount of frozen water reserves in this arid to hyper-arid region. The inventory was carried ...

Detecting droughts as early as possible is important in avoiding negative impacts on economy, society, and environment. To improve drought monitoring, we studied drought propagation (i.e., the temporal manifestation of a ...

While considerable attention has been devoted to how precipitation modulates net primary productivity in arid and semi-arid ecosystems, the emergence of multi-faceted controls on carbon (C) turnover suggests that there is ...

Patch‐size distribution and plant cover are strongly associated to arid ecosystem functioning and may be a warning signal for the onset of desertification under changes in disturbance regimes. However, the interaction ...
