Figure 2.5. Foraminifera (mean proloculus, frequency of R. annectens ,frequency of
angular-asymmetrical forms) concentrations in cores taken offshore from Kali River
in Western India. The abundance of R. annectens increases and the mean proloculus
size decreases during droughts (from Nigram et al ., 1995).
