Assimilation potential of water column biota: Mesocosm-based evaluations
(Tata Energy Research Institute, India, 2003)This chapter presents a generalized picture of various aspects of assimilation by native biota and underscores the importance of safeguarding the environment from excessive discharge of nutrient-rich effluents, even though ... -
Bacterial growth efficiency in a tropical estuary: Seasonal variability subsidized by allochthonous carbon
(Springer, 2007)Bacterial growth efficiency (BGE) is a key factor in understanding bacterial influence on carbon flow in aquatic ecosystems. Intra-annual variability in BGE, and bacteria-mediated carbon flow in the tropical Mandovi and ... -
Bacterial response to contrasting geochemistry in the sediments of central Indian Ocean basin
(Regional Research laboratory, Bhubaneswar, 2005)The latitudinal differences in geochemical and physiographic nature could evoke varied biological/microbiological response in the deep-sea benthic ecosystem of the Central Indian Ocean. Sediment cores have been examined ... -
Bioaccumulation of toxic metals by fish in a semi enclosed tropical ecosystem
(Taylor and Francis, 2006)Concentrations of Zn, Cd, Pb, and Mn in different tissues of 17 species of fish from a tropical estuary (Cochin backwaters) are presented. The metal electivity index (MSI) was found to be a better tool compared with the ... -
Bottom dwelling animals: Benthos
(WWF for Nature-India, 2004)The beaches of Goa are predominantly sandy, and occupy about 4000 ha of area along the north-south coastline. An important component of the sandy beaches in Goa re the sand dunes in the supralittoral region. The coastal ... -
Characterization and Ecophysiological Observations on Coastal Sand Dune Vegetation from Goa, Central West Coast, India
(University of Pune, 2011)Coastal Sand Dune flora (CSD) forms a specialized group of plants commonly referred as psammophytes. Goa has limited natural resources including beaches and sand dunes. The state is globally known for its tourism activities, ... -
Coastal ecosystem and environmental aspects of placer mining
(Allied, India, 2004)The world demand for mineral raw material is expected to increase more than threefold with the increase in population and the industrilization. Though, India's mineral resources generally appear to be sufficient to meet ... -
Cochin backwaters: A sad story of manipulation
(The Royal Swedish Academy of Sciences, 1997)Cochin backwaters, along the south west coast of India have been altered several times for various causes and the system has undergone tremendous environmental changes as a consequence developmental activities and associated ... -
Coliform and human pathogenic bacteria in tourism affected water bodies in North Goa
(Anon, 2002)Microscopic bacteria, which are diverse and preponderant in all ecosystems, sense changes in any environment fast because of their ability to metabolize a variety of chemical substances for their nutrition and growth. In ... -
Contribution of Phytoplankton Photosynthesis to a Mangrove Ecosystem
(Indian Association for Limnology and Oceanography, 1980)Primary production in a fringing mangrove ecosystem was measured using two techniques. The first estimated gross oxygen production and community metabolism based on the diel difference in dissolved oxygen concentrations. ... -
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 ... -
Coral reefs - Specialized ecosystems
(Anna University, India, 1990)This paper discusses briefly some aspects that characterize and differentiate coral reef ecosystems from other tropical marine ecosystems. A brief account on the resources that are extractable from coral reefs, their ... -
Deterioration in the biodiversity of copepods in sewage laiden creeks of Mumbai coast, west coast of India: A statistical approach.
(Council for Innovative Research, 2014)The coastal waters of Mumbai is known to receive copious amount of waste from the adjacent creeks and bays. Effluents from various industries including nuclear and thermal power stations are discharged into the Mumbai ... -
Ecology of the marine protists, the Labyrinthulomycetes (Thraustochytrids and Labyrinthulids)
(Urban & Fischer Verlag, 2002)The Labyrinthulomycetes, comprising Thraustochytrids and Labyrinthulids, are marine osmoheterotrophic straminipilan protists which have been isolated from a variety of habitats all over the world. The limited knowledge on ... -
Effect of shallow-water venting in Azores on a few marine biota
(Station Biologique de Roscoff, 2006)The 1000 m high D. Joao de Castro seamount lies in the middle of the Azores Archipelago (Portugal) on the hyperslow-spreading Terceira rift in the Atlantic. Hydrothermal vents were found near the top of the seamount and ... -
Environmental impact assessment - A management tool for conservation of large marine ecosystems
(Fishery Survey of India, 2004)Coastal development includes a variety of activities which will have significant impact on marine ecosystem especially in the shallow nearshore areas. The stress relevant to coastal zone emerge from hinterland activities, ... -
