Marine biosphere reserves - Need of the 21st century
(Academy of Environmental Biology, 1991)Worldwide awareness for the creation of Marine Biosphere Reserves has increased considerably due to the human depredation in many coastal areas and natural changes. Many important and unique plant and animal species have ... -
Echinoside-B from the Lakshadweep sea cucumber Actinopyga mauritiana (Quoy and Gaimard)
(NISCAIR, New Delhi, 1991)Brine-shrimp assay guided purification of the methanolic extract of the sea cucumber Actinopyga mauritiana yields echinoside-B as a major toxic constituent. The compound has been characterized based on its spectral data. -
Heterotrophic utilization of extracellular products of phytoplankton in a tropical estuary
(Cambridge University Press, 1991)Bacterial uptake of algal exudates has been estimated in a tropical estuary, Dona Paula, Goa, India, where the seasonal fluctuations in hydrographic and nutrient parameters as well as dissolved organic matter concentrations ... -
Seagrass habitat complexity and macroinvertebrate abundance in Lakshadweep coral reef lagoons, Arabian Sea
(Springer, 1991)Macrofauna of seagrass community in the five Lakshadweep atolls were studied and compared. The associated epifaunal and infaunal taxa comprising nine major taxonomic groups, showed significant differences in the total ... -
Subsurface chlorophyll maxima in the north-western Bay of Bengal
(Cambridge University Press, 1991)The depth profiles of phytoplankton pigments in the north-western Bay of Bengal are generally characterizEd. by a subsurface chlorophyll maximum. The occurrence of subsurface chlorophyll maxima is discussed in relation to ... -
Distribution and biomass estimation of shell-boring algae in the intertidal area at Goa India
(International Phycological Society, 1991)The distribution and frequency of shell-boring green and blue-green algae in the intertidal at Goa, India were studied. The green alga Gomontia sp. and the blue green algae Hyella caespitosa Bornet et Flahault, H. gigas ... -

Seasonal fluctuations in the occurrence of Cladocera in the Mandovi-Zuari estuarine waters of Goa
(NISCAIR, New Delhi, 1991)Annual fluctuations in environmental features were noticeable particularly in the concentration of salinity and nutrients. The cladocerans showed a wide range of salinity tolerance and exhibited positive correlation with ... -
Yeasts from the sediment samples of the EEZ along the southwest coast of India
(Marine Biological Association of India, 1991)Fiftyeight yeast isolates were obtained from the benthic sediment samples of 19 stations during R.V. Gaveshani Cruise No. 187 of the Exclusive Economic Zone along the southwest coast of India. The depths ranged from 20 to ... -
Ecological considerations in the assessment of marine fisheries

Socio-economic significance of mangroves in India
(International Society for Mangrove Ecosystems, Okinawa, Japan, 1991)Mangrove ecosystem is considered ecologically and economically important perhaps due to its high productivity. However, due to the lack of proper scientific knowledge as well as the rapid increase in various developmental ... -
Zooplankton of the lagoons of the Laccadives: diel patterns and emergence
(Cambridge University Press, 1991)Zooplankton populations in the water column increased substantially at night in four lagoons of the Laccadives. Epibenthic forms emerging into the water column during night, as well as non-epibenthic forms such as calanoid ... -
Population ecology and community structure of sub-tidal soft sediment dwelling macro-invertebrates of Konkan, west coast of India
(NISCAIR, New Delhi, 1991)Population density of benthos varied from 350 to 29,975 m super(-2) (X = 4325, SD = + or - 5939) in the study area. The fauna was mainly composed of Polychaeta (76.96%), Crustacea (4.93%), Echinodermata (4.36%) and other ... -

Estimates of high absolute densities and emergence rates of demersal zooplankton from the Agatti Atoll, laccadives
(American Society of Limnology and Oceanography, 1991)Direct sampling of the sandy substratus of the Agatti Lagoon with a corer showed the presence of vary high densities of epibenthic forms. On average, densities were about 25 times higher than previously estimated with ... -
Bathymetric distribution of Pleuromamma (Copepoda, Calanoida) species in the Indian Ocean
(ICAR, New Delhi, 1991)Based on the analysis of 204 zooplankton samples from the stratified depths in the Indian Ocean collected during the International Indian Ocean Expedition (IIOE), the distribution of the genus Pleuromamma indica, P. gracilis, ... -
