A note on the Pavonina flabelliformis D'Orbigny (benthic foraminifera) from the Arabian Sea
(Association of Korean Geoscience Societies, 1994)The detailed study of the inner shelf surface sediments off Karwar (India) revealed the occurrence of a benthic foraminiferal species Pavonina flabelliformis. This is the first report of this species in the Arabian Sea. ... -
Annual Variations in Zooplankton from a Polluted Coastal Environment
(Indian Association for Limnology and Oceanography, 1980)Seasonal changes in the composition and distribution of zooplankton from the coastal waters of Trivandrum were studied. The study indicated that the effluent discharged from a nearby titanium dioxide factory did not affect ... -
Carbohydrate-degrading bacteria closely associated with Tetraselmis indica: Influence on algal growth
(Inter-Research, 2012)The interactions between the algal species Tetraselmis indica and strains of bacteria are examined. Three bacterial strains were isolated and sequence analysis of the 16S rDNA indicated that the organisms belong to the ... -
Distribution of foraminifera in the lagoons of certain Islands of the Lakshadweep Archipelago, Arabian Sea
(CSIR-NISCAIR, 1987)A total of 107 foraminiferal species belonging to 29 families and 48 genera have been identified from the lagoonal sediments of Agatti, Kavaratti, Suhelipar, and Minicoy atolls of Lakshadweep. The fauna is dominated by ... -
Distribution, factor analysis and ecology of benthic foraminifera within inner shelf regime of Vengurla-Bhatkal sector, West Coast, India
(Geological Society of India, 1987)One hundred and two taxa of benthic foraminifera are reported from the neritic environment (15-60 m) of Vengurla - Bhatkal area. Q-mode factor analysis reveals 6 important foraminiferal assemblages accounting for 92% of ... -
Ecological evaluation of two prawn culture fields in the Cochin Backwater based on premonsoon diurnal observations
(Marine Biological Association of India, 1995)Extensive low lying areas of the Cochin Backwater peripheries at its lower reaches are bunded into interconnected ponds for paddy-cum-prawn culture. Results of a study of two representative ponds are reported. The ponds ... -
Ecological studies of Ulva reticulata Forsskal in Chapora bay (Goa)
(Indian Association for Limnology and Oceanography, 1986)The patchy occurrence of Ulva reticulata Forskal along the west coast of India lead to its ecological studies. The total annual yield of . reticulata calculated for 3800 sq. m. area of the bay amounts to 6.74 tonnes wet ... -
Ecological Studies on the Seasonal Production of the Edible Oyster, Crassostrea Madrasensis (Preston) in Cochin Backwater, Kerala
(Indian Association for Limnology and Oceanography, 1981)Seasonal variation in the standing crop of intertidal oyster Crassostrea madrasensis at Ramanthuruth and Vallarpadom in the Cochin backwater for the period July 1974 to December 1975 showed that the maximum yield (whole ... -
Ecology and trophic preference of picoplankton and nanoplankton in the Gulf of Mannar and the Palk Bay, southeast coast of India
(Elsevier, 2013)The Gulf of Mannar (GoM) and the Palk Bay (PB) are two least studied marine environments located between India and Sri Lanka. The environmental and smaller plankton (0.2–20 mu m) data from 30 locations in the GoM and PB ... -
Ecology of the Coexisting Copepod Species in Cochin Backwaters
(Indian Association for Limnology and Oceanography, 1980)Association between the common copepod species of Cochin backwaters were analysed. Grouping of the low saline and medium saline species generally stood separate from the high saline species. A high degree of correlation ... -
Ecology of the wood-boring bivalve Martesia striata (Pholadidae) in Indian waters
(Academic Press, 1999)Martesia striata is one of the dominant wood-boring organisms found in Indian waters. Incidence of this organism in the Zuari estuary (Goa) was evaluated by exposing wooden panels (Mangifera indica) to the marine environment ... -
