Genetic variation of reef-building polychaete Sabellaria chandraae in the south-eastern Arabian Sea based on mitochondrial COI gene
(2019)The honeycomb worm Sabellaria chandraae is the most common reef-building polychaete in the intertidal area along the south-eastern Arabian Sea. We used the mitochondrial cytochrome c oxidase subunit I (mtCOI) gene to examine ... -
Genetic variations in marine natural population - Measurement and utility in resource management and conservation: A review
(NISCAIR, CSIR, 1998)A number of molecular and biochemical tools which can be applied to the identification of species and the detection of genetic variation within species have been developed in recent years. All these methods rely on the ... -
Genome analysis of Marinobacter phage AS1 suggests its close interactions with host Marinobacter sp.
(2019)Marinobacter comprises a widespread and ecologically significant genus of marine bacteria with vast metabolic capabilities. However, very few reports on phages infecting this genus exist. In this study, we isolated and ... -
Genomic investigations provide insights into the mechanisms of resilience to heterogeneous habitats of the Indian Ocean in a pelagic fish
(Nature Publishing Group, 2021)The adaptive genetic variation in response to heterogeneous habitats of the Indian Ocean was investigated in the Indian oil sardine using ddRAD sequencing to understand the subpopulation structure, stock complexity, ... -
Genotoxic potency of mercuric chloride in gill cells of marine gastropod Planaxis sulcatus using comet assay
(Springer, 2015)In vivo and in vitro exposures were used to investigate the genotoxicity of mercuric chloride (HgCl<sub>2</sub>) to the marine snail, Planaxis sulcatus. The comet assay protocol was validated on gill cells exposed in vitro ... -
Genotoxicity of cadmium chloride in the marine gastropod Nerita chamaeleon using comet assay and alkaline unwinding assay
(Wiley, 2015)This paper presents an evaluation of the genotoxic effects of cadmium chloride (CdCl<sub>2</sub>) on marine gastropod, Nerita chamaeleon following the technique of comet assay and the DNA alkaline unwinding assay (DAUA). ... -
Genotoxicity of cadmium in marine diatom Chaetoceros tenuissimus using the alkaline Comet assay
(Springer, 2006)Genotoxic effects of Cadmium on phytoplankton Chaetoceros tenuissimus have been evaluated using DNA damage by comet assay. Cadmium concentrations ranging from 2.4 to 10 mg/L were used to evaluate the effects. Results showed ... -
Genotoxicity of two heavy metal compounds: lead nitrate and cobalt chloride in Polychaete Perinereis cultrifera
(Springer, 2017)The present study explores the in vivo and in vitro genotoxic effects of lead nitrate, [Pb(NO3)2] a recognized environmental pollutant and cobalt chloride (CoCl2), an emerging environmental pollutant in polychaete Perinereis ... -
Genus Haloptilus (Copepoda: Calanoida) from the Equatorial Region of the Indian Ocean
(Indian Association for Limnology and Oceanography, 1980) -
Geo-scientific investigations of gas-hydrates in India
(Indian National Science Academy, 2012)The best solution to meet India's overwhelming energy requirement is to tap the nuclear and solar power to the maximum extent possible. Another feasible major energy resource is gas-hydrates (crystalline substances of ... -
Geochemical and diatom records of recent changes in depositional environment of a tropical wetland, central west coast of India
(Springer, 2015)Two mudflat sediment cores collected from a sub-channel (S-61) and the main channel (S-60) of a tropical wetland, along central west coast of India, were investigated for recent changes in depositional environment using ... -
Geochemical and geological constraints on the composition of marine sediment pore fluid: Possible link to gas hydrate deposits
(Elsevier, 2012)Pore water sulfate consumption in marine sediments is controlled by microbially driven sulfate reduction via organo-clastic and methane oxidation processes. In this work, we present sediment pore fluid compositions of 10 ... -
Geochemical and isotopic signatures of surficial sediments from the western continental shelf of India: Inferring provenance, weathering, and the nature of organic matter
(Society for Sedimentary Geology, 2013)Bottom sediments from thirteen transects sampled mainly at depth contours of 30, 100, and 200 m along the western continental margin of India, falling in two offshore sectors from Dwaraka to Goa and Cape Comorin to Goa, ... -
Geochemical and mineralogical analysis of stone anchors from west coast of India: Provenance study using thin sections, XRF and SEM-EDS
(Elsevier, 2010)Stone anchors have been recovered along the Indian coast as a part of the maritime archaeological studies at the National Institute of Oceanography (NIO), Goa, India. Study of stone anchors provides clues to understand the ... -
Geochemical characterisation of major and trace elements in the coastal sediments of India
(Springer, 2010)Thirty-five surface sediment samples from the Indian continental shelf were recovered offshore from the mouths of the major rivers (Brahmaputra, Ganges, Narmada, Tapti, Godavari, Krishna and Cauvery) discharging into the ... -
Geochemical characteristics of basalts from Andaman subduction zone: Implications on magma genesis at intraoceanic back-arc spreading centres
(2019)This study reports new petrological and geochemical data for the ocean floor volcanic rocks dredged from the back?arc basin of the Andaman Sea and elucidates their geochemical characteristics and petrogenetic aspects to ... -
Geochemical characteristics of gold bearing boninites and banded iron formations from Shimoga greenstone belt, India: Implications for gold genesis and hydrothermal processes in diverse tectonic settings
(Elsevier, 2016)This paper is the first documentation of boninites from the Kudrekonda Formation of Shimoga greenstone belt (SGB) in western Dharwar Craton (WDC), India and the occurrence of native gold in the associated quartz veins. We ... -
