The authors reconstructed May–September precipitation over the Asian continent (58–558N, 608–1358E) back to AD 1470 on the basis of tree-ring data, historical documentary records, ice core records, and the few long-term instrumental data series available in the region. They employed the method of Regularized Expectation Maximization (RegEM) and applied it to 44 subregions within the continent. ...

the aim of this paper is to project extreme precipitation events in an arid and a semiarid station. in order to project climate change based on general circulation models (gcms), we have applied lars-wg[1] downscaling tool. this stochastic weather generator down-scaled the climate of two synoptic stations using hadcm3 model and a2 emission scenario for 2040. we extracted extreme precipitation e...

Shallow-rooted grasses and deep-rooted shrubs dominate arid ecosystems where nitrogen is concentrated in the upper layers of the soil and water is distributed throughout. Analysis of mineral nitrogen and absorption patterns using a tracer indicated that shrubs in Patagonia absorbed nutrients from the lower, relatively nutrient-poor layers of the soil. Are they, consequently, at a competitive di...
