    Regeneration and abnormality in benthic foraminifer Rosalina leei: Implications in reconstructing past salinity changes 

    Kurtarkar, S.R.; Nigam, R.; Saraswat, R.; Linshy, V.N. (Universita' degli Studi di Milano, 2011)
    A laboratory culture experiment has been conducted to assess the response of marginal marine benthic foraminifer Rosalina leei to salinity and associated pH changes. Live specimens of Rosalina leei were subjected to a range ...

    Hydrographic changes in the Agulhas Recirculation Region during the late Quaternary. 

    Naik, Dinesh K.; Saraswat, R.; Khare, N.; Pandey, A.C.; Nigam, R. (European Geosciences Union, 2014)
    The strength of Southern Hemisphere westerlies, as well as the positions of the subtropical front (STF), Agulhas Current (AC) and Agulhas Return Current (ARC) control the hydrography of the southwestern Indian Ocean. ...

    Need of paleoclimatic reconstructions to understand natural and anthropogenic climatic hazards 

    Nigam, R. (National Institute of Oceanography, India, 2008)
    To formulate the future plans for guarding against the furies of the nature, either due to natural or anthropogenic climatic disasters, understanding of paleoclimatic fluctuations, particularly of the Holocene is of immense ...

    Foramgeographical affinities of the west and east coasts of India: An approach through cluster analysis and comparison of taxonomical, environmental and ecological parameters of Recent foraminiferal thanatotopes 

    Katha, P.K.; Bhalla, S.N.; Nigam, R. (ONGC, India, 2000)
    Q-Mode cluster analysis of one hundred sixty species of Recent foraminifera from twenty nine Recent littoral-thanatotopes from 4000 km long coastal-stretch of India reveals that its west and east coasts belong to two ...

    Distributional pattern of benthic foraminiferal morpho-groups in the shelf region off Mangalore: Environmental implications 

    Khare, N.; Sinha, R.; Rai, A.K.; Nigam, R. (NISCAIR, CSIR, 1995)
    The foraminiferal population in 45 surface sediment samples (20-86 m water depth) off Mangalore, Karnataka, India, was divided into benthic and planktonic assemblages. Within the benthic community based on the external ...

    Effect of salinity induced pH/alkalinity changes on benthic foraminifera: A laboratory culture experiment 

    Saraswat, R.; Kouthanker, M.; Kurtarkar, S.R.; Nigam, R.; Naqvi, S.W.A.; Linshy, V.N. (Elsevier, 2015)
    The salinity of coastal waters in the vicinity of seasonally fresh water fed estuaries changes tremendously and reportedly affects the living calcite secreting organisms like foraminifera, as well as their dead remains. ...

    Does mining pollution affect foraminiferal distribution in Mandovi estuary, Goa, India? 

    Nigam, R.; Nayak, G.N.; Naik, S. (Museum d'histoire naturelle de Geneve, 2002)
    A total of 10 surface sediment samples were collected in the premonsoon season in 1990 from the Mandovi estuary, Goa, India. Study revealed presence of 14 species of foraminifera. The foraminiferal data is of special ...

    Can benthic foraminiferal morpho-groups be used as indicators of paleomonsoonal precipitation? 

    Nigam, R.; Khare, N.; Borole, D.V. (Academic Press, 1992)
    A technique is proposed for the quick and easy assessment of paleomonsoonal precipitation through the study of morphological groups of foraminifera in a shallow water (20 m water depth) sediment core collected off Karwar, ...

    Relict faunal testimony for sea-level fluctuations off Myanmar (Burma) 

    Panchang, R.; Nigam, R.; Raviprasad, G.V.; Rajagopalan, G.; Ray, D.K.; Hla, U Ko Yi (The Palaeonlological Society of India, 2008)
    The distribution and ecological significance of the relict benthic foraminiferal assemblage found in the study area off Myanmar is discussed here. Of the 126 surface sediments studied for foraminiferal content, relict ...

    Assessing the effect of calcein incorporation on physiological processes of benthic foraminifera 

    Kurtarkar, S.R.; Saraswat, R.; Nigam, R.; Banerjee, B.; Mallick R.; Naik, Dinesh K.; Singh, D.P. (Elsevier, 2015)
    Rosalina sp. was incubated in seawater spiked with calcein (5 mg/l to 20 mg/l calcein), a dye proposed as efficient marker to tag newly formed calcite, to understand its effect on benthic foraminifera. The experiment was ...
