Soil loss through erosion and its subsequent deposition is considered as an important challenge for watersheds. In this paper, attempt has been made to integrate the Revised Universal Loss Equation, rainfall climatology from merged IMD gauge-TRMM (1998–2015) soil hydraulic parameters delineate highly susceptible zones of Kosi River Basin (KRB), Bihar, India assessment watershed prioritization. The are calculated by using ROSETTA model. Afterwards, analytical hierarchy process based on...
Traces of mercury present in the ambient air has led world to talk about pollution environment that consequently resulted introduction Minamata Convention (MC) on Mercury, an international treaty mercury. It was signed 10th October 2013 Japan became effective from 16th August 2017. The is a global aims protect human health and anthropogenic emissions its compounds. MC recognizes as pollutant concern considering be capable long-range transport, persistent, bioaccumulate, which ultimately...
The present investigation aims to study the diversity of ciliates from different habitats in and around Delhi, India, correlation this with soil quality {agricultural lands (site 1 2), dump yards 3 4), sewage treatment plant 5), residential land 6), landfill 7) barren 8)}. Various physicochemical parameters samples were studied analysed for texture, interstitial water, pH, conductivity, total organic carbon, matter, nitrogen phosphorous content, using standard protocols. Seventeen ciliate...
Abstract The study is conducted to examine the climate change impact on rice Crop Water Requirement (CWR) and Net Irrigation (NIR) using NASA Earth Exchange Global Daily Downscaled Projection (NEX-GDDP) coupled with CROPWAT 8.0 model. maximum temperature (Tmax), minimum (Tmin), rainfall projections for baseline (years 1981–2015) future 2030 2040) under Representative Concentration Pathway (RCP) 4.5 were derived from NEX-GDDP. To reduce bias, linear scaling (LS) modified difference approach...
Globally, heavy metals are the major pollutants present in both terrestrial and aquatic ecosystems.Increase their concentration due to various anthropogenic activities is a matter of concern.Higher these known be toxic non-biodegradable nature.Eukaryotic microorganisms, ciliates can used as cellular tools assess study mechanisms overcome metal toxicity.Here we discuss, at level, effect toxicity on growth rate, behavioural morphological changes ciliates.At molecular stress genes like hsp70,...
The freshwater bodies of India are highly biodiverse but still understudied, especially concerning ciliates. Ciliates constitute a significant portion eukaryotic diversity and play crucial roles in microbial loops, nutrient recycling, ecosystem maintenance. present study aimed to elucidate ciliate three sites the Delhi region India: Okhla Bird Sanctuary (OBS), Sanjay Lake (SL), Raj Ghat pond (RJ). This represents first investigation into taxonomic richness ciliates using high-throughput DNA...
Pulses play a pivotal role in contemporary agriculture, influencing food security and climate change mitigation. Blackgram (Vigna mungo L.), with its nutritional richness adaptability, addresses malnutrition contributes to soil fertility. This study focuses on enhancing blackgram productivity Bundelkhand, Uttar Pradesh, addressing challenges through tailored variety selection balanced nutrient management. The experiment, conducted 2022, evaluated three varieties (Azad-3, IPU 10-26, 11-2) NPK...
Tetmemena saprai n. sp. was isolated from fresh-water samples collected Okhla Bird Sanctuary, Delhi, India and described based on its morphology, morphogenesis molecular markers, namely the small-subunit (SSU) rRNA gene internal transcribed spacers (ITS1-5.8S-ITS2). The morphological features of T. are as follows: colourless; rigid body with no cortical granules; water expelling vesicle about 15 µm in size, located below adoral zone membranelles near left margin; size 125–140 × 50–60 μm live...
The authors have analyzed twentieth-century precipitation extreme events from the climatic models participating in phase 5 of Coupled Model Intercomparison Project (CMIP5) generated by NASA (NEX-GDDP). This study is focused on long west flowing perennial Mahi River Basin (MRB) has great ecologically and economically significance basin India. A quantified using Expert Team Climate Change Detection Indices (ETCCDI) index. most suitable Global Models (GCMs), INMCM-4, MRI-CGCM3 ensemble mean...
Abstract The escalating issue of heavy metal pollution is a global concern, primarily due to its toxic and persistent nature, further exacerbated by continuous surge in concentrations above recommended thresholds. This study examines the spatial-temporal dynamics water quality along Yamuna River through physicochemical parameters, analysis, advanced approaches such as Heavy Metal Pollution Index (HPI) & Ecological Risk (ERI), multivariate statistical techniques (Principal Component...
