How much terrestrial precipitation is used by vegetation and how runs off, represents central issues in hydrologic science, ecology, climate change, even geopolitics. We present a theory for the water balance to predict fractional change streamflow due given changes temperature precipitation. The involves single parameter whose value derived under conditions of neither energy- nor water-limitat...

Abstract While the relationships between dry land surface conditions, heat, and aridity have been well‐established, few studies addressed whether global warming will affect ability of wet conditions to moderate high temperatures atmospheric aridity. Using Coupled Model Intercomparison Project Phase 6 models, we demonstrate that absolute changes in monthly maximum temperature distribution during...

Lichens play crucial roles in sustaining the functioning of terrestrial ecosystems; however, diversity and ecological factors associated with lichenised soil fungi remain poorly understood. To address this knowledge gap, we used a global field survey including information on fungal sequences topsoils from 235 ecosystems. We identified 880 phylotypes across nine biomes ranging deserts to tropica...

The present study aims to use remote sensing techniques and geographic information systems (GIS) in monitoring detecting droughts the steppe regions (Tiaret city as a model) during period (2002-2022). In pursuit of this aim, some indicators were used, such surface temperature index (LST), soil moisture (SMI), standardized difference vegetation (NDVI), aridity (AI). Depending on Terra satellite'...

Minimum data length is vital to guarantee accuracy in hydrological analysis. In practice, it sometimes determined by the experiences of hydrologists, leading selection acceptable minimum an arguable issue among hydrologists. Therefore, this study aims investigate impact on parameter estimation and model performance, especially for data-scarce regions. Using four primary datasets from river basi...
