A meteorological drought study is performed using monthly time scale data from three separate locations in southern Sindh, Pakistan. Rainfall and temperature have been used to identify the drought. These were transformed into indices known as standardized precipitation evapotranspiration index (SPEI) (SPI), which derived (the Hargreaves equation). In this study, two are compared for stations Ch...

Abstract Impacts of climate warming on forests vigour are forecasted to increase in magnitude. Yet it remains unclear how stand characteristics and competition modulate the relationship between tree growth gross primary production with drought. Here, we studied spatial variation density, basal area height modulates (Basal Area Increment, BAI growth), summer NDVI, as well their responses drought...

An 81-year-old male with myasthenia gravis developed a cutaneous infection with Mycobacterium marinum, which apparently resolved following local heat therapy. Five months later, the patient developed new skin lesions and pancytopenia. M. marinum was isolated from his bone marrow. Pulsed-field gel electrophoresis was performed to determine if the skin and bone marrow isolates were clonally relat...

We analyzed potential land degradation processes in semiarid regions worldwide using long time series of remote sensing images and the Normalized Difference Vegetation Index (NDVI) for the period 1981 to 2011. The objectives of the study were to identify semiarid regions showing a marked decrease in potential vegetation activity, indicative of the occurrence of land degradation processes, and t...

Within the context of climate change, it is of utmost importance to quantify the stability of ecosystems with respect to climate anomalies. It is well acknowledged that ecosystem stability may change over time. As these temporal stability changes may provide a warning for increased vulnerability of the system, this study provides a methodology to quantify and assess these temporal changes in ve...

We established polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and diagnostic PCR based on cytochrome C oxidase subunit I (COI) barcodes of Bungarus multicinctus, genuine Jinqian Baihua She (JBS), and adulterant snake species. The PCR-RFLP system utilizes the specific restriction sites of SpeI and BstEII in the COI sequence of B. multicinctus to allow its cleavage ...

Several studies have assessed droughts and vegetation considering climatic factors, particularly El Niño-Southern Oscillation (ENSO) at different latitudes. However, there are knowledge gaps in the tropical Andes, a region with high spatiotemporal variability. This research analyzed relationships between droughts, vegetation, ENSO from 2001–2015. Meteorological drought was using Standardized Pr...

Machine learning (ML) methods have shown noteworthy skill in recognizing environmental patterns. However, presence of weather noise associated with the chaotic characteristics water cycle components restricts capability standalone ML models modeling extreme climate events such as droughts. To tackle problem, this article suggests two novel hybrid based on combination machine (ELM) algorithm (WC...

Considering that the relationships between agrometeorological drought indices and impact of agricultural in Slovenia are not yet well understood, aim this study was to make an indicative evaluation success selected indices, addressing topsoil layer vegetation condition, detecting agriculture. In study, performance two established indices—the SPEI (standardised precipitation evapotranspiration i...
