Micropalaeontological proxies for understanding palaeoclimate
(National Institute of Oceanography, India, 2007)
Does temperature affect dimorphic reproduction in benthic foraminifera? A culture experiment on Rosalina leei
(Indian Academy of Sciences, 2000)
The possible effects of environmental factors on the dimorphic mode of reproduction in benthic foraminifera have been reported in the literature. Published observations based on field samples have indicated an inverse ...
Application of foraminifers in ecotoxicology: Retrospect, perspect and prospect
In view of the extensive use of foraminifers for the pollution monitoring especially their unmatched utility in deciphering the temporal variation in the type and concentration of pollutants at a given location, the ...
Otoliths in continental shelf and slope surficial sediments off Saurashtra, Arabian Sea, India and their significance
(New Academic Publishers, Delhi, 2001)
Otoliths are a viable and underutlized paleoceanographic tool. In India a considerable amount of work has been done on otoliths of the fresh water fishes, however no significant report is available for marine otoliths. In ...
Experiment to decipher the effect of heavy metal cadmium on coastal benthic foraminifer Pararotalia Nipponica (Asano)
(Palaeontological Society of India, 2013)
The response of benthic foraminifer Pararotalia nipponica to heavy metal cadmium is observed in laboratory experiment. The results indicate that under a given set of conditions, heavy metal cadmium is deleterious to benthic ...
Mean proloculus size, delta super(13) C and delta super(18) O variations in recent benthic foraminifera from the west coast of India and their climatic implications
(Indian Society of Earth Sciences, Calcutta, 1993)
The interrelationship between mean proloculus size (MPS), delta super(18) O and delta super(13) C vatiations in benthic foraminiferal species Rotalidium annectens and their relation with temperature (T) and salinity (S) ...
How will Benthic Foraminifera Respond to Warming and Changes in Productivity-: A Laboratory Culture Study on Cymbaloporetta plana
(John Wiley & Sons, 2019)
Anthropogenic activities are likely to cause global warming. Global warming will affect marine productivity and thus food availability for marine organisms. Both the seawater temperature and food availability affect benthic ...
Deglaciation in the tropical Indian Ocean driven by interplay between the regional monsoon and global teleconnections
High resolution climate records of the ice age terminations from monsoon-dominated regions reveal the interplay of regional and global driving forces. Speleothem records from Chinese caves indicate that glacial terminations ...
Benthic foraminifera are protozoa, which evolved during Cambrian and at present are found living in all possible marine environments. Their single cell is enclosed in a microscopic calcareous or agglutinated shell called ...
Foraminifers as indicators of marine pollution: A culture experiment with Rosalina leei
In order to develop a viable foraminiferal proxy for heavy metal pollutants, juvenile specimens of Rosalina leei were subjected to different mercury concentrations (0 -180 ng/l). Initially considerable growth was observed ...
