Abstract
Investigation of foraminifera assemblage through thirtyt-wo surface samples along the transect in Itapitangui river mangrove
was done in july / 89. Foraminiferal fauna composed mainly of Ammotium salsum, Arenoparrella Mexicana, Haplophragmoides
wilberti, Miliammina fusca and Trochammina inflata occur on mangrove area of Cananeia-Iguape estuary-lagoon system at bottom
salinity range from 6 to 30, bottom temperature range from18 -9°C and organic carbon percentage values range from 0.47 to 5.7.
The low diversity pattern of foraminiferal population inhabiting the mangrove area of Itapitangui River and the lack of foraminiferal
zonation is similar to that encountered in mangroves from all over the world.
In July 1989, a survey of foraminifera zoning was carried out by means of thirty-two surface samples along a transect in
the Itapitangui river mangrove, Cananéia-Iguape estuarine-lagoon system. The foraminifera fauna found is mainly composed of
Ammotium salsum, Arenoparrella mexicana, Haplophragmoides wilberti, Miliammina fusca and Trochammina inflata. This fauna
has been found in muddy and sandy sediments where the bottom salinity ranges from 6 to 30, the bottom temperature ranges from
18oC to 19oC, and the organic carbon content ranges from 0.47% to 5.70%. The diversity pattern of the foraminifera population
inhabiting the Itapitangui river mangrove area and the absence of zonation of foraminifera species are similar to those found in the
mangroves worldwide.
