Chaotic and Nonlinear Behavior of Arid Ecosystems to Outgoing Drivers
, although emerging new landscape are consequence of crossing critical transitions. Intrinsic and extrinsic thresholds can lead to effects that cascade among systems. The nonlinear response of ecosystem to environmental perturbation identifies by bifurcation...

Plant biodiversity monitoring and ecosystem management : A case study in Zayanderood riverside
Ecosystem management has become a keyword for describing new approaches to maintaining biodiversity in natural ecosystems and protected areas . Riverside areas are one of these ecosystems and because of their high biodiversity are focal points...
History of research on salt-affected lands of Iran: present status and future prospects : Halophytic Ecosystems :
Iran covers a total area of about 165 Mha in southwest Asia. Approximately 16% of the total land surface of the country..................
Polyphenol accumulation drives the dynamic of soil organic matter along snowmelt gradients in alpine tundra
Soils of arctic and alpine ecosystems sequester large amount of organic carbon, and the impact of climate forcing on these carbon stocks is a key issue in global carbon cycle studies. However, our understanding of the factors controlling Soil...
Decoupling of soil nutrient cycles as a function of aridity in global drylands
The biogeochemical cycles of carbon (C), nitrogen (N) and phosphorus (P) are interlinked by primary production, respiration and decomposition in terrestrial ecosystems1. It has been suggested that the C, N and P cycles could become uncoupled under...
