Involvement of inducible nitric oxide synthase (iNOS) in immune-functioning of Paphia malabarica (Chemnitz, 1782)
(Elsevier, 2019)In recent years, the role of inducible nitric oxide synthase (iNOS) isoform has been widely studied because of its immunological relevance in higher organisms as well as invertebrates including bivalves. However, little ... -
Community structure of benthic amphipods in four estuaries of northwest India
(Elsevier, 2019)This is the first comprehensive study of the community structure and spatial-temporal distribution of amphipods in estuarine sediments of northwest India. Specifically, amphipods from Ulhas, Amba, Kundalika and Savitri ... -
Variability of organic nitrogen and its role in regulating phytoplankton in the eastern Arabian Sea
(Elsevier, 2019)The relative importance of organic nitrogen (ON) and inorganic nitrogen (IN) as nitrogen sources for the phytoplankton communities were studied through a seasonal time series of nitrogen species in the eastern Arabian Sea. ... -
The ballast effect of lithogenic matter and its influences on the carbon fluxes in the Indian Ocean
(European Geosciences Union, 2019)Data obtained from long-term sediment trap experiments in the Indian Ocean in conjunction with satellite observations illustrate the influence of primary production and the ballast effect on organic carbon flux into the ... -
The first record of active methane (cold) seep ecosystem associated with shallow methane hydrate from the Indian EEZ
(Springer India, 2019)Here we report the discovery of cold-seep ecosystem and shallow methane hydrates (2-3 mbsf) associated with methane gas flares in the water column from the Indian EEZ for the first time. The seep-sites are located in the ... -
Sea level-controlled sediment transport to the eastern Arabian Sea over the past 600 kyr: Clay minerals and SrNd isotopic evidence from IODP site U1457
(Elsevier, 2019)Long marine sequences deposited in the Arabian Sea are suitable to study the orbital sensitivity of sediment dynamics from a source-to-sink perspective. The clay mineralogy and SrNd isotopic compositions have been analyzed ... -
A Printable Device for Measuring Clarity and Colour in Lake and Nearshore Waters
(Multidisciplinary Digital Publishing Institute- MDPI AG, Basel, Switzerland, 2019)Two expanding areas of science and technology are citizen science and three-dimensional (3D) printing. Citizen science has a proven capability to generate reliable data and contribute to unexpected scientific discovery. ... -
In vivo DNA damage in gill, haemolymph and muscle cells of whiteleg shrimp Litopenaeus vannamei on exposure to organophosphorus pesticide
(Inter-Research Science Center, Oldendorf/Luhe, Germany, 2019)In response to growing worldwide market demand, intensive shrimp farming, particularly of whiteleg shrimp Litopenaeus vannamei, has expanded tremendously. The present study investigated induced DNA damage in gill (GL), ... -
Pyrrole-Derived Alkaloids of Marine Sponges and Their Biological Properties
(Elsevier, 2019)Marine sponges remain an unambiguously significant source of secondary metabolites from marine invertebrates. It is estimated that more than 15,000 compounds have been discovered from marine sources, and new compounds are ... -
Evaluation of the reanalysis wind over the Indian Ocean across the seasonal reversing wind pattern
(NISCAIR-CSIR, India, 2019)Present study show the similarity as well as contradictory event among the four different wind data based on monthly, seasonally and annual wind pattern over Indian Ocean. All the four reanalysis wind sources exhibit almost ... -
Significant seasonal contrast in the Arabian Sea during deglaciation: Evidence from oxygen isotopic analyses of individual planktic foraminifera
(Elsevier, 2019)The variation of stable isotopes between individual shells of planktic foraminifera of a given species and size may provide short-term seasonal insight into past sea surface temperature (SST) and salinity (SSS). In this ... -
Impact of the Indian Summer Monsoon variability on the source area weathering in the Indo-Burman ranges during the last 21-kyr - A sediment record from the Andaman Sea
(Elsevier, 2019)The paleomonsoonal variations and their impact on the weathering patterns in the source regions of sediments of the Andaman Sea were investigated from a 21-kyr sedimentary record using environmental magnetic, clay mineralogical ... -
Extended distribution of Phtisica marina Slabber, 1769 (Crustacea: Amphipoda): first observation of alien Caprellid in the coastal waters of Indian subcontinent
(Regional Euro-Asian Biological Invasions Centre - REABIC, Helsinki, Finland, 2019)Phtisica marina, originally described by Slabber, 1769 from Netherlands, is one of the most abundant caprellid amphipod species reported from numerous regions around the globe and is primarily associated with fouling ... -
Spatiotemporal variation of alkaline phosphatase activity in coastal waters off Trivandrum
(Elsevier, 2019)Phosphatase is an extracellular enzyme which releases inorganic phosphate (Pi) from dissolved organic phosphate and indirectly organic carbon as nutrients for aquatic communities. Here, we have examined spatiotemporal ... -
Role of sulfur-oxidizing bacteria on the ecology in tropical mangrove sediments
(Elsevier, 2019)Mangroves are unique ecological niches for microorganisms which play major roles in biogeochemical cycles and in nutrient recycling. Sulfur compounds are primarily utilized by sulfur-oxidizing bacteria (SOB) and sulfate-reducing ... -
Metagenomic analysis of tarball-associated bacteria from Goa, India
(Elsevier, 2019)The beaches of Goa state in India are frequently polluted with tarballs, specifically during pre-monsoon and monsoon seasons. Tarballs contain hydrocarbons, including polycyclic aromatic hydrocarbons, which pose significant ... -
Gas transfer velocities of CO2 in subtropical monsoonal climate streams and small rivers
(European Geosciences Union, 2019)CO2 outgassing from rivers is a critical component for evaluating riverine carbon cycle, but it is poorly quantified largely due to limited measurements and modeling of gas transfer velocity in subtropical streams and ... -
Surface wave dynamics off Mumbai coast, north-eastern Arabian Sea
