Evidence of binary division in mature central capsules of a collosphaerid colonial radiolarian: Implications for shell ontogenetic patterns in modern and fossil species
(Coquina Press, 1998)Evidence is presented from fossil shells and living species of the colonial radiolarian Acrosphaera that maturer central capsules with shells can produce daughter central capsules and shells by binary fission. These data ... -

Structural characteristics of marine sedimentary humic acids by CP/MAS sup(13)C NMR spectroscopy
(Ifremer/ CNRS/ IRD/ Editions scientifiques et medicales Elsevier SAS. Tous droits reserves, 1998)Humic acids from sediments of different depositional environments have been studied by solid-state sup(13)C NMR and the results compared with the traditional wet chemical analysis. Results obtained are well in agreement ... -
Species composition, abundance and distribution of hydromedusae from Dharamtar estuarine system, adjoining Bombay Harbour
(Council of Scientific and Industrial Research, New Delhi, 1999)Species composition, abundance and distribution of hydromedusae from Dharamtar estuarine system, adjoining Bombay Harbour, Maharashtra, India were investigated during 1984-1985. Twenty six species belonging to 19 genera ... -
New record of the sympatric distribution of two Asian species of the horseshoe crab
(Current Science Association, Bangalore, India, 1999)The co-existence of two species of horseshoe crabs Tachypleus gigas and Carcinoscorpius rotundicauda along the Orissa and West Bengal Coast, India is reported. The study revealed that the two species were sympatric. The ... -
Zooplankton community of Bhayandar and Thane salt pans around Bombay
(Council of Scientific and Industrial Research, New Delhi, 1999)The zooplankton community of the salt pans of Bhayandar and Thane was studied based on the contribution of microzooplankton and meso-macrozooplankton. Population of microzooplankton was about 4 times more in Bhayandar as ... -
Marine fungi: A critique
(American Society for Microbiology, 1999)Obligate marine fungi, those which grow and sporulate exclusively under marine conditions, have received all the attention from marine mycologists. Fungi originating from freshwater, or terrestrial environment and capable ... -
Understanding marine microbes - Trends and future diections
(Indian National Science Academy, New Delhi (India), 1999)Microbes which form an integral part of any ecosystem including the marine ecosystem are represented by groups such as viruses, bacteria, fungi, diatoms, algae, protozoa etc. These being fundamental blocks of an ecosystem ... -
Distribution of hydromedusae from the exclusive economic zone of the west and east coasts of India
(Council of Scientific and Industrial Research, New Delhi, 1999)Distribution and abundance of hydromedusae from the exclusive economic zone of the west and east coasts of India is carried out based on zooplankton collections (on board FORV Sagar Sampada) during the period 1985-1990. ... -
Socioeconomic significance of mangroves for coastal people of India: A changing scenario
(Int. Soc. for Mangrove Ecosystems, Okinawa, Japan, 1999)The importance of mangrove ecosystems with particular reference to the coastal population of India has been realised recently. Natural calamities like cyclones, floods, famine, siltation and erosion are directly related ... -

Studies on experimental culture of a marine ciliate Fabrea salina
(Oxford and IBH, Calcutta, 1999)Studies were conducted on the culture of a marine ciliate, Fabrea salina in the laboratory condition. Three types of inert feed; commercial yeast, fermented wheat bran and fermented rise bran were tested to study their ... -
Abundance, viability and culturability of Antarctic bacteria
(Department of Ocean Development, New Delhi, India, 1999)The viability of total number of bacteria decide the mineralisation rate in any ecosystem and ultimately the fertility of the region. This study aims at establishing the extent of viability in the standing stock of the ...
