Proloculus size variation in Recent benthic foraminifera: Implications for paleoclimatic studies
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 ...
Graphic pattern of foraminiferal dominance in nearshore region of central west coast of India
(Indian Association for Limnology and Oceanography, 1979)
Within the inner neritic zone (0-55 m depth) along the central west coast of India, some foraminiferal groups such as @iAmmonia, Elphidium, Trochammina, Bulimina, Bolivina, Nonion, Nonionella@@ and Florilus@@ individually ...
Foraminiferal assemblages and their use as indicators of sediments movement: a study in the shelf region off Navapur, India
Factor analysis of 60 species of foraminifera from 13 stations off Navapur, reveals three major assemblages - Ammonia annectens, Ammonia papillosus-Asterorotalia dentata and Ammobaculites persicus assemblages. These ...
An aberrant Spiroloculina sp. from Recent sediments off Bombay-Daman, west coast of India
(Indian Association for Limnology and Oceanography, 1983)
A case of an abnormal two apertured Spiroloculina sp. was encountered in a sample from 90 m depth off Bombay-Daman. This was a case of regeneration/repair
Benthic foraminifera as pollution indices in the marine environment of west coast of India
(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 ...
Reproductive behaviour of benthic foraminifera: A key to palaeoclimate
(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 ...
Living benthonic foraminifera in a tidal environment: Gulf of Khambhat (India)
Living benthonic foraminifera from the top one centimeter layer from 23 surface sediment samples have been studied. Samples were collected from the tidally affected inner shelf off the Daman Bombay sector of the Arabian ...
Ecological regime and distribution of @iVirgulinella@@ spp. in the inshore sediments of western India
@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 ...
Influence of estuaries on shelf foraminiferal species
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 ...
Distribution, factor analysis and ecology of benthic foraminifera within inner shelf regime of Vengurla-Bhatkal sector, West Coast, India
(Geological Society of India, 1987)
One hundred and two taxa of benthic foraminifera are reported from the neritic environment (15-60 m) of Vengurla - Bhatkal area. Q-mode factor analysis reveals 6 important foraminiferal assemblages accounting for 92% of ...
