Remote sensing application for delineating coastal vegetation - A case study
(Current Science Association, Bangalore, 1997)Remote sensing data has been used for mapping coastal vegetation along the Goa Coast, India. The study envisages the use of digital image processing techniques for delineating geomorphic features and associated vegetation, ... -
Length and weight relationship of laboratory reared penaeid prawn Penaeus monodon (Fabricius) (Crustacea: Penaeidae)
(NISCAIR, CSIR, 1997)A parabolic relationship was obtained while studying the length-weight relationship of the postlarvae of Penaeus monodon. The b value (multiplying constant) showed that in the laboratory reared penaeid prawns, length-weight ... -
Diurnal variation in zooplankton in the Zuari Estuary, west coast of India
(Marine Biological Association of India, 1997)Variations in zooplankton biomass and population density in relation to the prevailing hydrographical conditions were studied in Zuari Estuary, Goa. The physico-chemical parameters showed limited variations. Zooplankton ... -
Influence of bacterial exopolymers and the adult extract of Balanus amphitrite and Cthamalus sp. on cyprid metamorphosis of Balanus amphitrite
(US Office of Naval Research, 1997)Settlement of barnacle, a major fouling organism is believed to be controlled to a great extent by substratum characteristics such as, presence of conspecific adults or "gregariousness" inducing factors. Exopolymers secreted ... -
Descriptions of five new species of Haplostylus (Mysidaceae crustacea) from South West Australia
(Cambridge University Press, 1997)The genus Haplostylus Kossmann was separated from the genus Gastrosaccus Norman to accept those species in which the endopod of the third pleopod of the male is uniarticulate. Bacescu (1973), Hatzakis (1977), Fenton (1990) ... -
Studies on the associates and parasites of zooplankton from southwest and southeast coasts of India
(Marine Biological Association of India, 1997)Associates and parasites of zooplankton from southwest and southeast coasts of India were studied. Among the epizoic forms two species of ciliates infesting copepods were new records from Indian waters. Eight species of ... -
Benthic disturbance and monitoring experiment in the Central Indian Ocean Basin
(Int. Society of Offshore and Polar Engineering, Colorado, USA, 1997)Environmental impact assessment studies for deep-sea manganese nodule mining have been initiated in the Central indian Ocean Basin since 1995. As a part of the first phase for collecting the benthic baseline data, echosounding, ... -
Anaerobic sulfide-oxidation in marine colorless sulfur-oxidizing bacteria
(Springer, 1997)Colorless sulfur-oxidizing bacteria are ubiquitous in Indian waters and have the ability to oxidize sulfide under anaerobic conditions. These bacteria can not only mediate the sulfur cycle oxidatively but also the nitrogen ... -
Population characteristics and mass culture of Macrostomum orthostylum Braun 1885 (Macrostomida: Turbellaria)
(Oxford and IBH, 1997)Population characteristics and mass culture of a brackish water turbellarian Macrostomum orthostylum were studied in the laboratory. Adult M. orthostylum has a maximum length of 1.5 mm and can survive for a maximum period ... -
Ecology of hydromedusae from Bombay Harbour - Thana and Bassein Creek estuarine complex
(NISCAIR, CSIR, 1997)Species composition, abundance, seasonal variation and distribution of Hydromedusae were carried out during October 1985 to September 1986. Thirty four species belonging to twenty two genera were recorded from this region. ... -

Larvicidal activity of some marine macrophytes against Artemia salina
(Society of Biosciences, 1998)Petroleum ether (PE) and chloroform (C) soluble fractions of methanolic extracts of nine different macrophytes viz. mangroves (Derris heptaphyla, Salvadora persica, Sonneratia caseolaris and Clerodendrum inerme), seaweeds ... -
Influence of divalent cations and pH adsorption of a bacterial polysaccharide adhesin
(Elsevier, 1998)Hyphomonas MHS-3 elaborates a diffuse capsular material, primarily composed of polysaccharide, which has been implicated to serve as the holdfast of this prosthecate marine bacterium. A purified polysaccharide (fr2ps) from ... -
CO sub(2) and N sub(2) O fluxes from the northern Indian Ocean
(Narosa, New Delhi (India), 1998)The CO sub(2) and N sub(2)O in the north Indian Ocean were measured and their fluxes were evaluated. Samples were collected from the Arabian Sea and the Bay of Bengal. The water samples were analysed for dissolved oxygen, ... -
Renieramycins H and I, two novel alkaloids from the sponge Haliclona cribricutis Dendy
(NISCAIR, CSIR, 1998)The known alkaloid, mimosamycin 1, along with its moon- and di hydroxy derivaties, 4-hydroxy mimosamycin 2 and 1, 4-dihydroxymimosamycin 3 and two new dimeric alkaloids: namely renieramycins H and I 4 and 5 have been ... -
Riverine input of chlorinated hydrocarbons in the coastal pollution
(The Pennsylvania Academy of Science, Easton, PA, USA, 1998)This chapter presents an overview of the contamination of the coastal ecosystem of the North Sea, Arabian Sea, Bay of Bengal, East China Sea, Atlantic Sea, Aegean Sea, East Java Sea, Australian coast and the Mediterranean ... -
Studies on the secondary metabolites from the Indian gorgonian Subergorgia suberosa: Isolation and characterization of four analogues of the cardiotoxin subergorgic acid
(American Chemical Society, 1998)Chemical investigation of the methanol extract of the Indian Ocean gorgonian coral Subergorgia suberosa resulted in isolation and identification of four novel compounds 2-5. Structural investigation revealed compound 1 to ... -
A heteroaromatic acid from marine sponge Suberites vestigium
(NISCAIR, CSIR, 1998)The 4-Methyl- pyrazole-3(5)-carboxylic acid has been isolated from the buttanol fraction of marine sponge, Sunerites vestigium for the first time. The methanol extract of the sponge exhibits in vitro antihistaminic activity. ...
