    Recent foraminifera along west coast of India: Restrospect, perspect and prospect 

    Nigam, R.; Khare, N. (Indian Academy of Geoscience, 1995)
    An immense quantum of work on foraminifera is being carried out in Indian waters by various research centers and universities. However, a thorough review of the foraminiferal studies from Indian waters is yet to be amde. ...

    Revealing monsoonal variability of the last 2,500 years over India using sedimentological and foraminiferal proxies 

    Khare, N.; Nigam, R.; Hashimi, N.H. (Springer-Verlag, 2008)
    A 2-m-long, shallow-water sediment core, representing the last 2,500 years, collected from the tropical Arabian Sea from the inner shelf (22 m water depth) off Karwar (Karnataka, India) near the mouth of the Kali River, ...

    Microenvironments and anomalous benthic foraminiferal distribution within the neritic regime of the Dabhol-Vengurla sector (Arabian Sea) 

    Setty, M.G.A.P.; Nigam, R. (Universita' degli Studi di Milano, 1980)
    An anomalous distribution of benthic Foraminifera within the neritic regime at a few stations indicates the existence of microenvironments. The vertical distribution is marked by the restricted occurrence of @iCibicides@@ ...

    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 ...

    Benthic foraminifera as pollution indices in the marine environment of west coast of India 

    Setty, M.G.A.P.; Nigam, R. (Universita' degli Studi di Milano, 1984)
    Two ecosystems affected by acidic pollutants (Thana Creek, Bombay and inshore area of Trivandrum, Kerala) and two other ecosystems affected by alkaline pollutants (Cola Bay, Goa and inshore area of Karwar, Karnataka) were ...

    Proloculus size variation in Recent benthic foraminifera: Implications for paleoclimatic studies 

    Nigam, R.; Rao, A.S. (Elsevier, 1987)
    Ratios of dimorphic (microspheric/megalospheric) forms of Foraminifera are affected by temperature and hence are useful in paleoclimatic studies. In some cases, however, it is not possible to distinguish between the dimorphic ...

    Reproductive behaviour of benthic foraminifera: A key to palaeoclimate 

    Nigam, R. (Indian Academy of Sciences, Bangalore, 1988)
    Many benthic foraminiferal species exhibit dimorphism associated with reproduction. The two resultant forms are known as microspheric and megalospheric forms. Culture studies, though limited in number, show that ratios of ...

    Influence of estuaries on shelf foraminiferal species 

    Nigam, R. (CSIR-NISCAIR, 1988)
    Dabhol-bhatkal stretch of the west coast of India is marked by a number of estuaries. Cavarotalia annectens is selected to monitor the influence of these estuaries on the inner shelf foraminiferal fauna. The percentage ...

    Benthic foraminifers as indices of diversity and hyposalinity in a modern clastic shelf regime, off Bombay, India 

    Setty, M.G.A.P.; Nigam, R. (New Delhi: Oxford & IBH, 1985)
    A tidally energized clastic shelf regime at 25-45 m depth off Bombay-Daman composed of silty sand, silty clay, and clay fractions is located between a sand bar and the coast. The sand bar, running parallel to the coast, ...

    Ecological regime and distribution of Virgulinella spp. in the inshore sediments of western India 

    Nigam, R.; Setty, M.G.A.P. (Elsevier, 1982)
    @iVirgulinella@@ Cushman, 1932 was distinguished as a subgenus from @iVirgulina@@ d'Orbigny, 1826 (non @iVirgulina@@ Bory, 1823 = @iFursenkoina@@) on the basis of the development of numerous small arched sutural openings ...
