Algal blooms: a perspective from the coasts of India
DeSilva, M.S.; Anil, A.C.; Naik, R.K.; DeCosta, P.M. (Springer, 2012)Algal blooms have been documented along the west and east coasts of India. A review of bloom occurrences in Indian waters from 1908 to 2009 points out that a total of 101 cases have been reported. A comparison of the bloom ... -
Dinoflagellate community structure from the stratified environment of the Bay of Bengal, with special emphasis on harmful algal bloom species
Naik, R.K.; Hegde, S.; Anil, A.C. (Springer, 2011)Harmful algal blooms (HABs) have been documented along the coasts of India and the ill effects felt by society at large. Most of these reports are from the Arabian Sea, west coast of India, whereas its counterpart, the Bay ... -
First report of toxic Prorocentrum rhathymum (Dinophyceae) and its pigment composition from coastal waters of the eastern Arabian Sea
Naik, R.K.; Damare, S.R.; Yapa, K.K.A.S.; DeCosta, P.M.; Roy, R. (2018)Prorocentrum rhathymum,a toxic dinoflagellate, was isolated for the first time from coastal waters of the eastern Arabian Sea. Batch cultures were grown and cell pellets were extracted in methanol for analysis of algal ... -
Karlodinium veneficum in India: Effect of fixatives on morphology and allelopathy in relation to Skeletonema costatum
Naik, R.K.; Chitari, R.R.; Anil, A.C. (Current Science Association, 2010)Dinoflagellates form an important component of marine and freshwater phytoplankton. They are a remarkably diverse and complex group with various modes of nutrition and ability to produce toxins, and are major contributors ... -
Phytoplankton community structure at the juncture of the Agulhas return front and subtropical front in the Indian Ocean sector of Southern Ocean: Bottom-up and top-down control
Naik, R.K.; George, J.V.; Soares, M.A.; Devi, A.; Anilkumar, N.; Roy, R.; Bhaskar, P.V.; Murukesh, N.; Achuthankutty, C.T. (Elsevier, 2015)The juncture of the Agulhas Return Front (ARF) and Subtropical Front (STF) in the Indian Ocean sector of Southern Ocean (SO) is characterized by high mesoscale turbulence, which results in sporadic, short lived phytoplankton ... -
Primary description of surface water phytoplankton pigment patterns in the Bay of Bengal
Naik, R.K.; Anil, A.C.; Narale, D.D.; Chitari, R.R.; Kulkarni, V.V. (Elsevier, 2011)Spatial and temporal variations in surface water phytoplankton pigment distribution in the Bay of Bengal were studied during the spring intermonsoon (SpIM, February–April) and the commencement of the summer monsoon (CSM, ... -
Primary productivity in the Karwar Bay, Karnataka, west coast of India
Naik, U.G.; Naik, R.K.; Nayak, V.N. (MKK Publication, 2006)The measurement of primary production is of great importance because of its significance to the problems of aquatic ecology and fishery management. The interaction of light intensity, temperature and nutrient levels ... -
Response of bacteria and phytoplankton from a subtropical front location Southern Ocean to micronutrient amendments ex-situ
Ramaiah, N.; Jain, A.; Meena, R.M.; Naik, R.K.; Verma, R.; Bhat, M.; Mesquita, A.; Nadkarni, A.; D`Souza, S.E.; Ahmed, T.; Bandekar, M.; Gomes, J. (Elsevier, 2015)The effects of micronutrient amendments such as cobalt (Co), copper (Cu), iron (Fe) and their mixture (Co+Cu+Fe) on bacterial abundance, phytoplankton, bacterial community (BC) composition were examined at a subtropical ... -
Response of polar front phytoplankton and bacterial community to micronutrient amendments
Jain, A.; Meena, R.M.; Naik, R.K.; Gomes, J.; Bandekar, M.; Bhat, M.; Mesquita, A.; Ramaiah, N. (Elsevier, 2015)In a shipboard microcosm experiment we manipulated cobalt (Co), copper (Cu), iron (Fe), and Fe+Co availability in surface water samples collected during austral summer of 2013 from a Polar front (PF) location in the Indian ... -
Skeletonema (Bacillariophyceae) in Indian waters: A reappraisal
Naik, R.K.; Sarno, D.; Kooistra, W.H.C.F.; DeCosta, P.M.; Anil, A.C. (NISCAIR, CSIR, 2010)The planktonic diatom genus Skeletonema is common in Indian coastal waters. Recent taxonomic studies have uncovered high diversity in this genus, and it is expected that several species occur also in the highly diverse ...
