Evaluation of single and joint effect of metabolites isolated from marine sponges, Fasciospongia cavernosa and Axinella donnani on antimicrobial properties.
(Elsevier, 2014)The biochemical mechanisms that marine sponges have developed as a chemical defense to protect themselves against micro and subsequent macrobiofouling process might comprise a potential alternative for the preventing attack ... -
Design and synthesis of marine natural product-based 1H-indole-2,3-dione scaffold as a new antifouling/antibacterial agent against fouling bacteria.
(Elsevier, 2014)Marine organisms such as seaweeds, sponges and corals protect their own surfaces from fouling by their high anesthetic, repellant, and settlement inhibition properties. Within the marine ecosystem, evolution has allowed ... -
Diseases of corals with particular reference to Indian reefs
(India: IUCN, 2012)Diseases are one of the factors that change the structure and functioning of coral-reef communities as they cause irreversible damage to the corals Reports on coral diseases describe the etiological agents responsible for ... -
Temporal variations in the wind and wave climate at a location in the eastern Arabian Sea based on ERA-Interim reanalysis data.
(European Geosciences Union, 2014)Temporal variations in wind speed and significant wave height (SWH) at a location in the eastern Arabian Sea are studied using ERA-Interim reanalysis data from 1979 to 2012. A shallow water location is selected for the ... -
Spatiotemporal distribution in phytoplankton community with distinct salinity regimes along the Mandovi estuary, Goa, India.
(Scientific and Technological Research Council of Turkey, 2014)Seasonal variations in the composition and abundance of phytoplankton were investigated fortnightly at 3 different regions along the Mandovi estuary from June 2007 to May 2008 in relation to salinity and nutrients. A total ... -
Abrupt climate-induced changes in carbonate burial in the Arabian Sea: Causes and consequences.
(American Geophysical Union, 2014)We present high-resolution records of aragonite contents and pteropods abundance in two sediment cores (SK 17 and MD 76–131) within the Oxygen Minimum Zone (OMZ) of the eastern Arabian Sea. We show large increases in ... -
Marine and semi-synthetic hydroxysteroids as new scaffolds for pregnane x receptor modulation.
(MDPI Publishing, 2014)In recent years many sterols with unusual structures and promising biological profiles have been identified from marine sources. Here we report the isolation of a series of 24-alkylated-hydroxysteroids from the soft coral ... -
Multi-hazards coastal vulnerability assessment of Goa, India, using geospatial techniques.
(Elsevier, 2014)The state of Goa in West India has a 105 km long coastline with beaches and cultural heritage sites of significant importance to tourism. The increasing incidence of tropical cyclones in the Arabian Sea in recent decades ... -
Spectral wave characteristics off Gangavaram, Bay of Bengal.
(Springer, 2014)Spectral wave characteristics were studied based on waves measured for 1 year during 2010 off Gangavaram, Bay of Bengal. Maximum wave height of 5.2 m was observed on 19 May 2010 due to the influence of cyclonic storm LAILA. ... -
Stone anchors of India: Findings, classification and significance.
(APCONF 2014 Organizing Committee, 2014)Various types of stone anchors have been observed during inshore and offshore explorations along the east and west coasts of India. The earliest stone anchors of India have been recorded from the Harappan sites (3rd ... -
Benthic mineralization and nutrient exchange over the inner continental shelf of western India.
(European Geosciences Union, 2014)The western Indian continental shelf is one of the most productive coastal systems of the world ocean. This system experiences extreme changes in its oxygen regime, being normoxic from November to May and suboxic ... -
Intra- and inter-seasonal variability of nutrients in a tropical monsoonal estuary (Zuari, India).
(Elsevier, 2014)A study was conducted to understand the intra- and inter-seasonal variability of dissolved oxygen and nutrients in a tropical monsoon estuary (Zuari in Goa, India). We adopted a dual sampling approach with (a) daily or ... -
Early- to late-Holocene contrast in productivity, OMZ intensity and calcite dissolution in the eastern Arabian Sea
(SAGE Publications, 2014)The Oxygen Minimum Zone (OMZ) is a potential source of CO<sup>2</sup> to the atmosphere, and the extensive OMZ spread to 1.37 × 10<sup>6</sup> km<sup>2</sup> in the Northern Arabian Sea would be an important contributor ... -
Recent developments towards the synthesis of Varitriol: An antitumour agent from marine derived fungus Emericella variecolor.
(Bentham Science Publishers, 2014)Marine natural products are recognized as a fruitful source of drug development due to their rare structural entities and diverse biological activities, and consequently, publicized number of metabolites as new medicines. ... -
Nitrate reducing activity pervades surface waters during upwelling.
(Elsevier, 2014)Nitrate reducing activity (NRA) is known to be mediated by microaerophilic to anaerobic bacteria and generally occurs in the sub-surface waters. However, we hypothesize that NRA could become prominent in the surface waters ... -
Interactions of bacteria with diatoms: Influence on natural marine biofilms.
(John Wiley & Sons, 2014)Interactions between microfouling components influence the biofilm community and the cascading events, thus playing an important role in the biofouling process. Bacteria and diatoms are among the dominant forms reported ... -
A comparative study on mesozooplankton abundance and diversity between a protected and an unprotected coastal area of Andaman Islands.
(Springer, 2014)The study was carried out to understand the variability in phytoplankton production (Chlorophyll a) and mesozooplankton diversity from two different shallow coastal regions of south Andaman viz. Port Blair Bay (PBB), the ... -
Structure-function elucidation of a new alpha-Conotoxin, Lo1a, from Conus longurionis.
(American Society for Biochemistry and Molecular Biology, 2014)Alpha-Conotoxins are peptide toxins found in the venom of marine cone snails and potent antagonists of various subtypes of nicotinic acetylcholine receptors (nAChRs). nAChRs are cholinergic receptors forming ligand-gated ... -
Diversity, occurrence and socio-economic aspects of snappers and job fish (Family: Lutjanidae) fisheries from Gulf of Mannar region, south-east coast of India.
(CSIR-NISCAIR, 2014)Survey were conducted in nine fish landing centres (Pamban South, Mandapam South, Keelakarai, Ervadi, Vembar, Tharuvaikulam, Thirespuram, Tuticorin and Amalinagar) along the Gulf of Mannar region to assess the diversity, ... -
Organic enrichment and benthic fauna–Some ecological consideration.
(NISCAIR, 2014)In the present study, synoptic data on the structure of macroinfauna and total organic content of sediment collected from different sources were analyzed to look for patterns of association consistent with conceptual model ...
