Mercury in sediments of Ulhas estuary
(Elsevier, 2003)Hg levels in water, suspended particulate matter and sediment of the Ulhas estuary are under considerable environmental stress due to the indiscriminate release of effluents from a variety of industries including chlor-alkali ... -
Nitrite-induced enhancement of toxicity of phenanthrene in fish and its implications for coastal waters
(Elsevier, 2003)Coastal areas are prone to varying degrees of anthropogenic chemical contamination. In many coastal environments experiencing reducing conditions in the water column, nitrite is produced as a result of denitrification. ... -
Evaluation of mangrove ecosystem of India for assessing its vulnerability to projected climatic changes
(World Wide Fund for Nature-India, 2003)Mangrove habitats of ecological and socio-economic significance, forms thrust area under coastal zone management programme of the country. Global warming is expected to result in the global sea level rise affecting various ... -
Response of benthic fauna to different pollutants: Some case studies and relevance of benthos to environmental impact assessment
(Discovery Publishing House, 2003)With rapid rate of urbanization, industrial growth and varieties of anthropogenic changes, the use of biological parameters as monitors of environment is being increasingly appreciated. As compared to plant, the animal ... -
Numerical analyses of soft bottom macroinvertebrates to diagnose the pollution in tropical coastal waters
(Springer, 2003)Soft bottom benthic organisms especially polychaetes are known to adapt as r or k selected strategies to different gradients of pollution. This will result in changes of benthic community structure from that of normal ... -
Coastal vegetation: Patterns in a tourist region
(Tata Energy Research Institute, India, 2003)None of the coastal areas under study possess the rich sand dune flora characteristic of an undisturbed beach. The status of dune vegetation in tourism villages has been deteriorating as compared to that in the developing ... -
Distribution and diversity of marine flora in coral reef ecosystems of Kadmat Island in Lakshadweep archipelago, Arabian Sea, India
(Smithsonian Institution, 2003)The coral reef of Kadmat Island of Lakshadweep was assessed for its biological components along with relevant hydrological characteristics. Corals were represented by 12 species, the most dominant being Acropora and Porites. ... -
Seasonal shift in net ecosystem production in a tropical estuary
(American Society of Limnology and Oceanography, 2003)Net ecosystem production was examined in the Mandovi and Zuari estuaries (southwestern India) and the adjoining coastal waters for a period of 1 yr (January to December 1998). The study period encompassed premonsoon, ... -
Environmental pollution detection and bioremediation by marine bacteria
(Discovery Publishing House, 2003)Microorganisms, in particular bacteria, play far more important ecological roles in natural environments than their small sizes would suggest. The environment for bacteria is everything that surrounds and sustains them ... -
Unusual rise in mercury-resistant bacteria in coastal environs
(Springer, 2003)A sharp rise in mercury-resistant bacteria (MRB) capable of tolerating very high concentration of Hg was observed over the last 3-4 years in the coastal environs of India. While none or negligible colony-forming units (CFU) ... -
The seagrasses of India
(University of California Press, 2003)The major seagrass meadows in India exist along the southeast coast (Gulf of Mannar and Palk Bay) and in the lagoons of islands from Lakshadweep in the Arabian Sea to Andaman and Nicobar in the Bay of Bengal. The flora ... -
Procedure for studying population genetic aspects of marine organisms using biochemical techniques
(Central Institute of Fisheries Education, India, 2003)Starch gel electrophoresis is being used in laboratory at the NIO for separation of enzymes (isozymes/allozymes), general proteins and hemoglobins of fish species. This technique is also applicable to other organisms. ... -
Coral reef ecosystem
(SAGE, India, 2003)Briefly discuss coral reefs in general and the Indian reefs in particular. While the ecology, growth forms and distribution of the reefs are well known and need only be mentioned briefly, the constraints to their sustainability ... -
Status of a seagrass ecosystem: An ecologically sensitive wetland habitat from India
(The Society of Wetland Scientists, 2003)Seagrasses in shallow sheltered regions of estuarine, brackish, and marine environments are of productive and ecological importance. The major seagrass meadows in India exist along the southeast coast (Gulf of Mannar and ... -
Benthic life on the tropical sandy shore: Miramar beach a case study
(Discovery Publishing House, 2003)Sandy beaches are a dynamic environment in equilibrium, where sand, water and air are in motion, absorbing the energy of the waves and constituting one of the most important aspects of the coastline. Though sandy beaches ... -
Bacterial growth efficiency in the tropical estuarine and coastal waters of Goa, southwest coast of India
(Springer, 2003)Bacterial growth efficiency (BGE) is an index of organic carbon passing through bacteria in an aquatic system. BGE values of natural bacterioplankton assemblages were measured in tropical estuarine and adjacent coastal ... -
Environmental influences on the trawl catches in a bay-estuarine system of Goa, west coast of India
(Elsevier, 2003)The degree of relationship between trawl catch and environmental variables was assessed in a bay-estuarine system of Goa, west coast of India using multivariate techniques. The demersal fish assemblage was dominated by the ... -
Barnacle larval destination: piloting possibilities by bacteria and lectin interaction
(Elsevier, 2003)Modulation of metamorphosis in barnacles in response to cues of biological origin is established. The bacteria associated with the barnacles also have a role in such modulations. We isolated the bacteria, Pseudomonas ... -
