Daily variations in pathogenic bacterial populations in a monsoon influenced tropical environment
Changing climatic conditions have influenced the monsoon pattern in recent years. Variations in bacterial population in one such tropical environment were observed everyday over two years and point out intra and inter ...
Penicillin-mediated changes in viable benthic diatom assemblages – insights about the relevance of bacteria across spatial and seasonal scales.
(CSIRO Publishing, 2014)
Penicillin, a beta-lactam antibiotic, cannot affect diatoms directly but does so through bacteria. Its effects on viable benthic diatom assemblages in a tropical environment were evaluated across spatial (intertidal sandflat, ...
Influence of darkness on pigments of Tetraselmis indica (Chlorodendrophyceae, Chlorophyta)
In the photic zone, phytoplankton experience diurnal variation in light intensity. However, prolonged exposure to aphotic condition influences their physiological state. Pigment composition is a useful biomarker to decipher ...
Occurrence of cyanobacteria - diatom symbiosis in the Bay of Bengal: Implications in biogeochemistry
(Current Science Association, 2010)
Diazotrophs (N sub(2) fixing organisms), mainly belonging to cyanobacteria, form a major group of phytoplankton in nutrient poor oligotrophic oceans. These organisms support non-diazotrophic phytoplankton community and ...
Asymmetric cell division and its role in cell fate determination in the green alga Tetraselmis indica
(Indian Academy of Sciences, 2015)
The prasinophytes (early diverging Chlorophyta), consisting of simple unicellular green algae, occupy a critical position at the base of the green algal tree of life, with some of its representatives viewed as the cell ...
Guidance on Port Biological Baseline Surveys (PBBS)
(GEF-UNDP-IMO GloBallast Partnerships, IOI, NIO, IUCN, 2014)
This publication has been prepared by GBP, IOI, CSIR-NIO and IUCN in order to serve as guidance to those who are planning to carry out a port biological baseline survey, in particular in the context of Ballast Water ...
Spatial distribution of dinoflagellates from the tropical coastal waters of the South Andaman, India: Implications for coastal pollution monitoring
Dinoflagellate community structure from two semi-enclosed areas along the South Andaman region, India, was investigated to assess the anthropogenic impact on coastal water quality. At the densely inhabited Port Blair Bay, ...
Phytoplankton community structure in relation to environmental factors from the New Mangalore Port waters along the southwest coast of India
(Springer International Publishing, 2018)
Seasonal and spatial phytoplankton distribution in relation to environmental factors was investigated in New Mangalore Port, a major port along the west coast of India. A well-mixed water column characterized the non-monsoon ...
Biofouling Community Structure in a Tropical Estuary of Goa on the West Coast of India
(ASEAN Committee on Science and Technology (COST), 2018)
Biofouling community structure was studied in a tropical monsoon-influenced Mandovi estuary in Goa, west coast of India. Monthly, seasonal and yearly observations on biofouling on polyvinyl chloride (PVC) panels immersed ...
