Health status of the coastal waters of Mumbai and regions around
(Bookwell, New Delhi, India, 2000)The coastal marine environment of Mumbai, Maharashtra, India and regions around receives the domestic wastewater generated of around 1800 million litres per day (mld), mostly untreated. In addition, a large number of ... -
Comparative toxicity of water soluble fractions of four oils on the growth of a Microalga
(Walter de Gruyter, Berlin, 2000)Toxic effects of water soluble fractions (WSF) of four different fuel oils on a microalga. Tetraselmis gracilis, were examined and compared. On applying different concentrations of WSF, a decrease in cell population was ... -
A comparative study on growth performance and biochemical composition of mixed culture of Isochrysis galbana and Chaetoceros calcitrans with monocultures
(Elsevier, 2000)The growth performance, biochemical composition and nutritive value of the mixed culture of Isochrysis galbana and Chaetoceros calcitrans, grown in batch cultures under laboratory conditions was compared with those in ... -
Fungi from marine habitats: Application in bioremediation
(Elsevier, 2000)This paper synthesizes the work done on decolourization of bleach plant effluent and synthetic dyes using fungi from marine habitats. Three fungi obtained from marine habitats removed up to 60-95% of Kraft paper mill bleach ... -
Annual cycle of metabolites in relation to breeding and feeding in Ambassis commersoni in Goa waters
(Society of Biosciences, 2000)Seasonal variations in moisture, proteins, carbohydrates, lipids and ash content in both the sexes of Ambassis commersoni were studied separately over an annual cycle (1989-1990). The results indicate that percentage of ... -
Parthenogenetic reproduction of Diaphanosoma celebensis (Crustacea: Cladocera): influence of salinity on feeding, survival, growth and neonate production
(Springer, 2000)Effect of salinity on the feeding rate and parthenogenetic reproduction of asexual females of the cladoceran Diaphanosoma celebensis Stingelin was studied. Short-term (10 h) grazing experiments were conducted using Isochrysis ... -
Distribution of deep-sea benthos in the proposed mining area of Central Indian Basin
(Taylor and Francis, 2000)During the first stage of the project work on the Indian Deep-Sea Environment Experiment (INDEX), the abundance and distribution of deep-sea benthos were surveyed in the Central Indian Basin for the collection of baseline ... -
Response of meiofauna to immediate benthic disturbance in the Central Indian Ocean Basin
(Taylor and Francis, 2000)Twenty-four stations (12 each, during pre- and postdisturbance studies) 5300 to 5330 m deep between 10 degrees 01 and 10 degrees 03'S latitude and between 75 degrees 59' and 76 degrees 02'E longitude were sampled to study ... -
Thraustochytrid protists as a component of marine microbial films
(Springer, 2000)Although ubiquitous in the marine environment, the presence and importance of thraustochytrid fungoid protists in primary film formation of freshly immersed surfaces in the sea have not been investigated. Thraustochytrids ... -
Benthic disturbance and impact experiments in the Central Indian Ocean Basin
(Taylor and Francis, 2000)As a part of the Environmental Impact Assessment studies for nodule mining, a long-term program has been initiated in the Central Indian Basin. Multidisciplinary studies on geological, biological, physical and chemical ... -
Some aspects of integrated coastal zone management in India
(Indian Institute of Remote Sensing, Dehradun (India), 2000)The coastal zone which lies roughly between the seaward margin of the continental shelves (to a depth of about 200 m) and the inland limits of the coastal plains (to a similar height of 100 m in altitude) encompasses the ... -
Antibacterial activity of the sponge Ircinia ramosa: Importance of its surface-associated bacteria
(Springer, 2000)Variations in the antibacterial activity of the sponge Ircinia ramosa were evaluated during two collection periods (January and May) against vicinity fouling bacteria (VFB) and sponge surface-associated bacteria (SAB). The ... -
Epibiotic community of the horseshoe crab Tachypleus gigas
(Springer, 2000)Horseshoe crabs act as moving substrata for simple to complex communities of small marine organisms. Amplexed adult pairs migrate for breeding once every 2 weeks from deep waters towards nearshore waters during highest ... -
Population genetics of drifting (Calanus spp.) and resident (Acartia clausi) plankton in Norwegian fjords
(Cambridge University Press, 2000)Kaartvedt distinguished between drifting and resident plankton and hypothesized that the latter were distinguished by their ability to maintain their horizontal position in desired habitats (Kaartvedt, 1993). In this study, ... -
Detection of luciferase gene sequences in nonluminescent bacteria from the Chesapeake Bay
(FEMS, 2000)A 745-bp luxA fragment was amplified from Vibrio harveyi (UM 1503), radiolabeled, and used as a probe to detect and quantify luxA genotypes in culturable bacterial populations from the Chesapeake Bay. DNA samples from 53 ... -
Fluxes of diatoms in the Dona Paula Bay, west coast of India
(Cambridge University Press, 2000)Sediment traps were deployed at a station in the Dona Paula Bay, Goa, India to collect sedimenting particles at weekly intervals from November to May during 1995-1997. Sedimented particles were analysed for total diatom ... -
Constituents of Chondria armata
(Pergamon, 2000)A novel long chain fatty ester, pentyl hentriacontanoate 1 and an orange red pigment, caulerpin 2 have been isolated and characterised from a red alga Chondria armata. The pigment caulerpin hitherto known to be a constituent ... -
Use of a chiA probe for detection of chitinase genes in bacteria from the Chesapeake Bay
(FEMS, 2000)PCR primers specific for the chiA gene were designed by alignment and selection of highly conserved regions of chiA sequences from Serratia marcescens, Alteromonas sp., Bacillus circulans and Aeromonas caviae. These primers ... -
