Abstract The Amazon is hypothesized to reach an irreversible ‘tipping point’ when deforestation slows the hydrological cycle sufficiently that tropical forest ecosystems cannot be sustained. However, inception of such a tipping point has not been supported by observations and relevant links between atmospheric moisture recycling are poorly understood. Here we show reduction in evapotranspiratio...

groundwater drought is a natural hazard that develops when groundwater systems are affected by climatical drought, when climatical drought occures, first groundwater recharge, later groundwater levels and groundwater discharge decrease. the origin of drought is a deficit in precipitation and that takes place in all the elements that comprise the hydrological cycle (flow in the rivers, soil mois...

Using the climate change experiments generated for the Fourth Assessment of the Intergovernmental Panel on Climate Change, this study examines some aspects of the changes in the hydrological cycle that are robust across the models. These responses include the decrease in convective mass fluxes, the increase in horizontal moisture transport, the associated enhancement of the pattern of evaporati...

a r t i c l e i n f o a b s t r a c t The isotopic composition of precipitation (δ P) is one of the most widely used and informative terrestrial paleoclimate proxies. δ P integrates a series of hydrological processes; therefore, any interpretation of paleohydrology using δ P requires a thorough understanding and quantification of the full hydrological cycle. In this paper, we use modern data to...

mirnas are endogenous small noncoding rnas that can regulate many cellular processes. different expression levels of several mirnas have been detected in glioblastomas. function of mirnas and targets have been well studied in recent years. according to these studies, the role of mirnas in glioblastoma pathogenesis have been defined. mirnas have affected many processes in gbm such as apoptosis, ...
