Marine biodiversity and ecosystem functioning: A perspective
Raghukumar, S.; Anil, A.C. (Indian Academy of Sciences, 2003)Biodiversity and community structure are now recognized to be important determinants of ecosystem functioning. In this regard the marine ecosystem has been studied to a much lesser extent compared to the terrestrial. This ... -
Marine fungi: A critique
Raghukumar, S.; Raghukumar, C. (American Society for Microbiology, 1999)Obligate marine fungi, those which grow and sporulate exclusively under marine conditions, have received all the attention from marine mycologists. Fungi originating from freshwater, or terrestrial environment and capable ... -
Mechanism of the biological response to winter cooling in the northeastern Arabian Sea
Madhupratap, M.; PrasannaKumar, S.; Bhattathiri, P.M.A.; DileepKumar, M.; Raghukumar, S.; Nair, K.K.C.; Ramaiah, N. (Macmillan, 1996)The Arabian Sea is one of the most biologically productive ocean regions, mainly due to the upwelling of nutrients during the summer (southwest) monsoon. But the northern Arabian Sea continues to sustain fairly high ... -
Molecular evidence of fungal signatures in the marine protist Corallochytrium limacisporum and its implications in the evolution of animals and fungi
Manohar, C.S.; Raghukumar, S.; Kasbekar, D.P.; Raghukumar, C. (Elsevier, 2006)Fungi, animals and single-celled organisms belonging to the choanozoans together constitute the supergroup Opisthokonta. The latter are considered crucial in understanding the evolutionary origin of animals and fungi. ... -
Morphology and physiology of the marine straminipilan fungi, the aplanochytrids isolated from the equatorial Indian Ocean
Damare, V.S.; Raghukumar, S. (NISCAIR, CSIR, 2006)While thraustochytrids, a group of unicellular marine straminipilan protists, have been found to be abundant in the water column, little is known of aplanochytrids. These constitute one of the 3 groups belonging to the ... -
Occurrence of the Tharaustochytrid, @iCorallochytrium limacisporum@@ gen. et. sp. nov. in the coral reef lagoons of the Lakshadweep Islands in Arabian Sea
Raghukumar, S. (Walter de Gruyter, Berlin, 1987)A new thraustochytrid protist, @iCorallochytrium limacisporum@@ gen. et sp. nov. is described from the waters of the coral reef lagoons of Agatti, Kavaratti and Bingaram belonging to the Lakshadweep group of islands in the ... -
Occurrence of thraustochytrid fungi in corals and coral mucus
Raghukumar, S.; Balasubramanian, R. (NISCAIR, New Delhi, 1991)Occurrence of thraustochytrid fungi in corals, fresh coral mucus and floating and attached mucus detritus from the Lakshadweep Islands in the Arabian Sea was studied. Corallochytrium limacisporum Raghukumar, Thraustochytrium ... -
Physical forcing of biological productivity in the northern Arabian Sea during the northeast monsoon
PrasannaKumar, S.; Ramaiah, N.; Gauns, M.; Sarma, V.V.S.S.; Muraleedharan, P.M.; Raghukumar, S.; DileepKumar, M.; Madhupratap, M. (Pergamon, 2001)Time-series observations at a nominally fixed location in the northern Arabian Sea (21 degrees N, 64 degrees E) during the Northeast Monsoon (winter, February) of 1997 showed the prevalence of cold sea-surface temperatures ... -
Preliminary studies on the association between zooplankton and the stramenopilan fungi, Aplanochytrids
Damare, V.S.; Damare, S.R.; Ramanujam, P.; Meena, R.M.; Raghukumar, S. (Springer, 2013)The relationship of the marine heterokont stramenopilan protists, the aplanochytrids, with the zooplankton was studied in coastal waters. The aplanochytrids were fed to the zooplankton specimens and observed for grazing ... -
Relevance of biofilm bacteria in modulating the larval metamorphosis of Balanus amphitrite
Khandeparker, L.; Anil, A.C.; Raghukumar, S. (Blackwell Publishing, 2006)Balanus amphitrite, on its larval metamorphosis. The effect of multispecies bacterial film was also assessed. The production of different molecules by the bacteria was influenced by the nutrient media under which they were ... -

Seasonal variations in carbon biomass of bacteria, thraustochytrids and microzooplankton in the northern Arabian Sea
Ramaiah, N.; Raghukumar, S.; Gauns, M.; Madhupratap, M. (Elsevier, 2005)As a part of the JGOFS-India Programme, abundance of heterotrophic bacteria (Hbac; 0-2000 m), thraustochytrids (0-2000 m), microzooplankton (0-200m occasionally up to 300 m) as well as bacterial growth rates (0-500 m) were ... -
Spatial and temporal distribution of fungi and wood-borers in the coastal tropical waters of Goa, India
Vishwakiran, Y.; Thakur, N.L.; Raghukumar, S.; Yennawar, P.L.; Anil, A.C. (Walter de Gruyter Berlin, 2001)Marine wood-degrading fungi are believed to contribute to the settlement and growth of wood-borers in the sea. However, little information is available on the association between species of these two groups of organisms. ... -
