Nitrogen uptake by size-fractionated phytoplankton in mangrove waters
(Inter Research, 2005)Seasonal changes in the uptake of nitrogenous nutrients (nitrate, nitrite, ammonium and urea) in 2 size fractions (netplankton: 20 to 200 Mu m; and nanoplankton: 0.8 to 20 Mu m) were studied in relationship to the phytoplankton ... -
Extracellular polysaccharide production by Thraustochytrid protists
(Springer, 2005)Four strains of marine stramenopilan protists, the thraustochytrids, were studied for their ability to produce extracellular polysaccharides (EPSs). Observations by light and scanning electron microscopy revealed the ... -
Manganese oxidation by bacterial isolates from the Indian Ridge System
(Springer, 2005)The abundance and activity of culturable manganese-oxidizing bacteria were assessed from near-bottom water samples of the tectonically active Carlsberg Ridge. Retrievable counts as colony forming units (CFU) on dilute ... -
Biological characteristics of Central Indian Basin waters during the southern summer
(Taylor and Francis, 2005)Phytoplankton biomass, taxonomy, primary productivity, and photosynthetically available radiation (PAR) were studied as part of baseline data collection for prospective nodule mining in the Central Indian Basin during the ... -
Butyltin compounds in the oyster, Saccostrea cucculata, from the West Coast of India
(Springer, 2005)Oganotins, especially tributyltin (TBT) compounds, are used in a wide range of applications including stabilizers in the PVC industry, plastic additives, industrial catalysts, insecticides, fungicides, bactericides, wood ... -
Response of DNA, proteins, lipids and antioxidant enzymes as measure of toxicity to mercury exposures in green mussel Perna viridis
(Asian Fisheries Society Indian Branch, 2005)Studies on exposures of gills of green-lipped mussel Perna viridis to sublethal levels of mercury (Hg) indicates that oxidative stress marker like lipids peroxidation and protein carbonyl content increase. With the exception ... -
The biology of the Arabian Sea and Bay of Bengal
(Angkor, India, 2005)This article focusses on the variability in physics and chemistry of the region and investigate its influence on the biology. This article is largely based on the recent observations made during the India JGOFS and BOBPS ... -
Molecular evidence for long-distance colonization in an Indo-Pacific seahorse lineage
(Inter Research, 2005)Mitochondrial control region (mtDNA CR) diversity within and among 6 seahorse populations associated with the Indo-Pacific Hippocampus kuda complex (H. kuda from India, Malaysia, Indonesia and the Philippines, H. fuscus ... -
Biofilm diatom community structure: Influence of temporal and substratum variability
(Taylor and Francis, 2005)Diatoms, which are early autotrophic colonisers, are an important constituent of the biofouling community in the marine environment. The effects of substratum and temporal variations on the fouling diatom community structure ... -
Rise of the dormant: Simulated disturbance improves culturable abundance, diversity, and functions of deep-sea bacteria of Central Indian Ocean Basin
(Taylor and Francis, 2005)The abundance of baroduric bacteria from nine sediment cores (0-10 cm below sea floor) was examined for their response to simulated benthic disturbance in the Central Indian basin (CIB). While the total counts of bacteria ... -
A tendem mass spectrometric approach for determining the structure of molecular species of ceramide in the marine sponge, Haliclona cribricutis
(IM Publications, 2005)Ceramides are important intracellular second messengers that play a role in the regulation of cell growth, differentiation and programmed cell death. Analysis of these second messengers requires a sensitive and specific ... -
Potential impact of sand mining on macrobenthic community at Kalbadevi Beach, Ratnagiri, West coast of India
(Allied, India, 2005)The intertidal area at Kalbadevi, Ratnagiri has been identified as one of the potential sites for placer minerals along the west coast of India. Considering the prospects of commercial mining, benthic sampling was conducted ... -
Evaluation of trophic state and plankton abundance from the environmental parameters of Visakhapatnam Harbour and near-shore waters, east coast of India
(Scientific Publishers, 2005)The present work describes the nutrient indices of the Visakhapatnam harbour and near-shore waters. The inner channels of Visakhapatnam harbour are considered to be eutrophic while near-shore waters (coastal and inshore ... -

Mesozooplankton of the Arabian Sea: Patterns influenced by seasons, upwelling, and oxygen concentrations
(Elsevier, 2005)The intensive study of the Arabian Sea during the 1990s included mesozooplankton investigations by the Netherlands, United Kingdom, Pakistan, India, Germany and the United States. Several major discoveries resulted. First, ... -
Seasonal variations in carbon biomass of bacteria, thraustochytrids and microzooplankton in the northern Arabian Sea
(Elsevier, 2005)As a part of the JGOFS-India Programme, abundance of heterotrophic bacteria (Hbac; 0-2000 m), thraustochytrids (0-2000 m), microzooplankton (0-200m occasionally up to 300 m) as well as bacterial growth rates (0-500 m) were ... -
A predictive regression model for the geochemical variability of iron and manganese in a coral reef ecosystem
(Taylor and Francis, 2005)This article focuses on the influence of nutrient forms (nitrogen/phosphorous forms) and parameters like pH and organic carbon in the distributional characteristics of two important trace metals, viz. iron and manganese, ... -
Response of sedimentary nucleic acids to benthic disturbance in the Central Indian Basin
(Taylor and Francis, 2005)Information on the response of nucleic acids (i.e., DNA and RNA) to simulated benthic disturbance was obtained from samples collected from eight sediment cores (0-10 cm) located in the Central Indian Basin (CIB). In general ... -
