Drought entails important effects on tree physiology, which may result in short- to long-term radial growth decreases. While the majority of studies have focused on annual drought-related variability of growth, relatively little is known about sustained growth decreases following drought years. We apply a statistical framework to identify climatic factors that induce abrupt growth decreases and...

Assessing incidence and trends of droughts floods can provide essential information for better water resource management, particularly in the context ongoing climate change. The present study has examined prevalence drought flood events Godavari basin, India, last four decades using Standardized Precipitation Evapotranspiration Index (SPEI) 3 months 9 months, their Mann–Kendall’s test Sen’s slo...

Drought is an extremely dangerous natural hazard that causes water crises, crop yield reduction, and ecosystem fires. Researchers have developed many drought indices based on ground-based climate data various remote sensing data. Ground-based are more accurate but limited in coverage; while the cover larger areas poor accuracy. Applying data-driven models to fuse multi-source for reproducing co...

BACKGROUND Typhoid fever remains a worldwide problem, but it is particularly common in Southeast Asia, including Indonesia. The causative agent Salmonella Typhi is known to have significant genome plasticity. METHODOLOGY This study describes genetic fingerprints using restriction fragment length polymorphism with SpeI of chromosomal DNA and pulsed-field gel electrophoresis (PFGE) of S. Typhi ...

A new multiscale Standardized Precipitation Evapotranspiration Index (SPEI) dataset is provided for a reference period (1960–1999) and two future time horizons (2040–2079) (2060–2099). The historical forcing based on combined climate observations reanalysis (WATer global CHange Forcing Dataset), the projections are fed by Fast Track experiment of Inter-Sectoral Impact Model Intercomparison Proj...

The current study was conducted to compute SPI and SPET drought indices due to their multi-scale concept and their ability to analyze different time-scales for selected meteorological stations in Karoon Basin. Regionalization of SPI and SPEI Drought indices based on clustering analysis was another aim of this study for hydrological homogenizing. Accordingly, to run test through data and determi...

The genomic structure and the restriction maps were studied in 24 Brucella strains isolated from marine mammals. From SpeI restriction profiles, the strains could be ascribed to three clonal groups, each corresponding to a specific host. Cross contamination between exclusively terrestrial and exclusively marine hosts is unlikely suggesting the divergence of the different species of the genus Br...

Abstract The increasing divergence/disagreement between the meteorological drought indicators, majorly due to changing climate conditions, has disputed their pertinency in monitoring and modeling of events. In present study, we attempted quantify divergence widely used indices such as standardized precipitation index (SPI), evapotranspiration (SPEI), newly developed net (SNEPI) traced evolution...

Machine learning (ML)-based models are popular for complex physical system simulation and prediction. Lake is the important indicator in arid semi-arid areas, to achieve proper management of water resources a lake basin, it crucial estimate predict dynamics, based on hydro-meteorological variations anthropogenic disturbances. This task particularly challenging regions, where scarcity poses sign...
