Abstract

The paper describes the variations in ecological parameters and their possible
role on vertical distribution of meiobenthic communities in the estuarine marshy
environment at Goa. The investigations conducted during post monsoon season
suggest that hydrobiological parameters are regulated by local attributes
such as land use pattern and coastal processes. Further, the variation in environmental
characteristics had direct relationship with meiobenthic population
density and its variations. Among biological parameters the sediment Chlorophyll
a (Chl a) was found to be closely related with meiobenthic density (r=
0.89: p<0.001). The fauna showed higher concentration at 0-2 cms layer. Subsequently,
as the depth increased, there was significant decrease in the density of
meiobenthic organisms. Another conspicuous observation made in the present
study was abundant supply of organic carbon up to a depth of 5 cm.
